Once you have a 3D printer, you need to get some filament. Filament is the material that creates the objects on your 3D printer. It comes on a spool and feeds into the 3D printer, melting to create the object you’re printing. PLA filament is recommended for beginners due to its ease of use and affordability. Some recommended PLA brands include Filamentum, Proto Pasta, Polymaker, TH3D, and Coex 3D.
Next, you’ll need to assemble your 3D printer. Follow the manufacturer’s manual that came with your 3D printer to set it up, including software or slicer setup and configuring your 3D printer for the first print. Most 3D printers these days come mostly assembled and take around 30 minutes to set up.
Once your 3D printer is set up and you have your filament, you need to choose your first 3D model to print. Many websites offer free and paid models, such as Thingiverse and MyMiniFactory. You can also create your own 3D models using CAD software like Tinkercad, Blender, SketchUp, or Fusion 360.
After selecting a 3D model, you’ll need to prepare it for printing using slicing software. Slicing software converts your model into a file that the printer can read by slicing it into layers. Most slicers have built-in profiles for common printers, making setup easier.
With your model sliced, you’re ready to start printing. Save the file to an SD card and insert it into your printer, then follow the printer’s instructions to begin the print. Monitor the print progress and make adjustments as needed.
Once the print is finished, remove it from the build plate, remove any excess material or support structures, and admire your finished 3D print. With a little knowledge and the right tools, you can create amazing 3D objects and embark on your journey into 3D printing.
How Does 3D Printing Works
A conventional printer can print images or text on paper, but a 3D printer has the capability to produce tangible objects. This means that with a 3D printer, you can create virtually any object you desire. It’s not surprising that in the future, the 3D printer market will likely evolve to the point of constructing buildings. Understanding the workings of a 3D printer is aided by 3D animation, but I will provide some insights into the key components of this remarkable technology that can help you establish a successful business.
A 3D printer features a nozzle with a diameter typically ranging from 0.2mm or more. The smaller the diameter of the nozzle, the higher the quality and clarity of the resulting object. Typically made of brass or stainless steel, the nozzle extrudes plastic in a semi-liquid form, with a temperature ranging between 200 to 300 degrees Celsius. This melted plastic, known as filament, is composed of pure polymer with a low melting temperature.
To heat the filament, a heat block is positioned above the nozzle, containing a thermostat to regulate temperatures within the range of 200 to 300 degrees Celsius. A thermocouple is installed to monitor the temperature accurately. The nozzle is tightly secured to one side of the heat block, while a heat break is positioned on top to prevent heat from rising excessively. A heat sink, attached to a part of the heat break, aids in dissipating excess heat, supplemented by a cooling fan to prevent overheating during prolonged operation.
Occasionally, prolonged printing sessions may cause filament to melt within the heat sink, obstructing the passage of new filament, a phenomenon known as “heat creep,” necessitating cleaning of the heat sink. To facilitate the extrusion process, a stepper motor applies forward force to the filament, utilizing a gear mechanism to guide filament movement.
The stepper motor operates with high torque, utilizing a step angle of 0.9 degrees, allowing for precise control. This motor is commonly utilized in robotics due to its reliability and accuracy.
Before commencing 3D printing, objects are designed within 3D software, such as Tinkercad or Blender. These software tools are extensively covered in our 3D animation course, offering comprehensive instruction in modeling and animation techniques. Once the object is designed, it is loaded into the 3D printer’s system.
The 3D printer reads the file, adjusts the nozzle, activates the motors, and heats the plastic within the heat block. Objects are constructed on the printer’s bed, where the hot plastic is extruded from the nozzle. The bed is controlled by a stepper motor, moving in the Y-axis, while a separate stepper motor controls the movement of the head unit in the X-axis.
For vertical movement in the Z-axis, another stepper motor, attached to a threaded rod, raises or lowers the head unit. This comprehensive control in all three axes enables the 3D printer to fabricate objects with precision, mirroring the capabilities of human craftsmanship.
During printing, the nozzle continuously extrudes melted plastic, layer by layer, until the object is completed. This additive printing technique, known as fused deposition modeling, ensures minimal waste and high efficiency. A tube connects the extruder to the head unit, transmitting pressure to ensure proper filament extrusion.
The potential of 3D printing is immense, with projections indicating significant market growth. As the technology advances, it will likely find applications in various industries, including aerospace, construction, and healthcare. To fully leverage the capabilities of a 3D printer, proficiency in 3D modeling and animation is essential, underscoring the importance of comprehensive training programs like our 3D animation course. While the field of 3D animation offers considerable opportunities, the integration of 3D printing provides an additional avenue for future success.
3D Printing Technology – The Future of Manufacturing
3D – You must have heard this term before. You might have watched a 3D movie at some point. Doesn’t everything feel so real? It’s like you’re not watching a movie but seeing a real thing. It feels as if you can reach out and touch it. It’s like an experience that leaves a long-term impact on your mind. Now this technology has also come into printing. Until now, whatever we printed came out on paper, whether it was black and white or colored photocopies or images. But in 3D printing, that thing is exactly copied. It’s as if you printed a car, it comes out exactly like that, which you can touch and feel as if you’ve got a toy in your hands. Have you ever been to a shopping complex and seen a model of the apartment complex kept at the entry point?
The same model is a 3D model. Nowadays, when the concept of big projects is prepared, it is shown exactly as it will look when it’s ready through 3D models to engineers, planners, or companies for better understanding, so that people get clarity. Suppose you draw a glass and then get a 3D model of it made, people can hold that glass in their hands and see it. That’s the work of a 3D printer. This technology is in high demand nowadays. If you’re a science student, you’ll understand it better, and if not, then in this documentary by Team T, we’ll explain it to you in simple language and discuss every angle of it. So, stay with us till the end. Let’s describe 3D very easily. You might have seen life hack videos these days, they are flooding social media, they also appear on your timeline. In these videos, you must have seen that a liquid comes out of a pen-type thing and quickly dries up and becomes hard.
So, whatever thing you made with it becomes like a structure. 3D printing works in the same way. Whatever machine or software it works with, a robotic mechanism makes that thing, then you take it out and use it as you like, whether you use it for decoration, as a showpiece, or fulfill your purpose. Understanding the origin of 3D printing technology is also necessary. Charles Hull is the inventor of stereolithography, which is the first commercial rapid prototyping technology, commonly known as 3D printing. This technology is used in sports shoes, aircraft components, artificial limbs, artworks, musical instruments, clothing, and almost every sector nowadays, where the product is prepared after making its model.
Charles Hull was involved in developing UV curable resins to make lamps. When he first thought about this method while working on it, he thought of curing photo-polymer resin using UV light and joining it. Then in 1986, he became the co-founder of 3D Systems Company and commercialized his technology along with the STL file format, which was capable of translating CAT software data for 3D printers. Today, 3D Systems is continuously innovating with its technology because 3D printers have become a growing hobby in today’s market, which is being used on a large scale. Hull, who has a degree in engineering physics from the University of Colorado, has received The Economist’s Innovative Award for his contribution to 3D printing technology.
3D printing is said to be the future of manufacturing. Let’s understand it in simple language. There was a time when having a telephone connection at home was a big deal.

If made using traditional assembly lines, it would require more time and investment. Since acquiring Morris Technologies in 2013, the company has been utilizing this technology for large-scale production. They have over 300 3D printers and have set a target to produce nearly 1 million additive parts.
Another global brand after General Electric is Boeing. You must have heard of Boeing or traveled on its aircraft. Most airplanes are made by Boeing. Boeing has been using 3D printing for a long time, having already produced more than 20,000 3D printed parts for military and commercial planes. The company also supports additive manufacturing programs at the University of Sheffield and the University of Nottingham, where aerospace engineering is taught using 3D printing technology. Now let’s come back to India. Indian toy industry should also adopt 3D printing technology on a large scale. If you are familiar with Hindu mythology, you will know that there is no better example of this technology than the divine cow that fulfills every wish or the wish-fulfilling tree. It’s clear that what you input into 3D printing is the same output you receive, in the desired shape and size.
The history of toys in the Indian subcontinent is linked to the Indus Valley Civilization and has now become a multi-billion dollar industry. Since the advent of plastic toys in India, this industry has been reaching new heights. The Indian toy market has a market cap of nearly 50 crores with an injection of about 2250 crores. The demand for Indian toys overseas is increasing, and there is an expected 25% growth in the Indian toy market from 2017. It was predicted in 2017 that the 3D printing industry worldwide will earn approximately $9 billion annually.
Therefore, toy manufacturers should see it as an opportunity to take the toy manufacturing process to global standards using 3D printing technology. Even today, the Indian toy industry is advancing on traditional methods, while the trend is towards custom-made products. We now spend a lot of time selecting toys in toy stores, and most children are attracted to foreign toys and cartoon characters because they look so attractive. So, even though toys made from 3D printing are expensive, the profit that should belong to our country’s manufacturers goes abroad. Talking about the advantages of 3D printing in the Indian industry, compact desktop printers are now available, eliminating the need to buy heavy manufacturing machines and requiring less space to occupy.
If printers start to be used, the demand in the market will increase, so the companies manufacturing them will start making cheaper printers themselves. In such cases, children often say that they want a certain toy, and if they don’t find it in the toy shop, they become sad and upset. In such a situation, seeing it being made with their own eyes will be a different experience. So, even if you can’t afford a 3D printer, you can design your desired toy using a 3D printing pen. This will also enhance children’s creativity. 3D printing pens are available online in the range from 4 to 5000, making it easy for you to prepare your structure at home. How is 3D printing technology being used in education? When we talk about 3D printing technology, children of the 80s and 90s were reading everything from maps to life science lessons in books until they finished their schooling.
In those days, there was some lack in learning and understanding. But nowadays, children are watching on projectors. There are smart classrooms where online teaching takes place, and to enhance children’s understanding, 3D printed objects are being explained abroad. Not only that, in geography class, critical geographical structures’ models are being used for better understanding. In science class, if the teacher has the same-to-same human organs in their hands, children will also take more interest in studying. Maintenance of 3D printed objects is also less, and they last longer. Similarly, in medical studies, 3D printed body parts, human skeletons, and dental structures are being used extensively.
Many times, it happens that a lot of money has to be spent on traditionally made things. For science projects, if students themselves try to make them, it’s a very hard job, while 3D printed models will be cheaper and can be forwarded as well. Similarly, instead of showing historical figures in pictures, students will read holding them in their hands, so they will be more interested in subjects like history, which are not boring at all. Many children say that students’ interest can increase, meaning that 3D printing technology can increase students’ interest. If you have questions like how much 3D printing machines will cost in your country and whether they are affordable, you will get the answer here. In terms of purpose, the price of 3D printing machines in India varies. If you check online, you will find that.
Hiring charges, warranty period, raw material costing, you need to know everything. It’s essential for you to understand the types of 3D printers we’re talking about so that you can understand what they’re used for and what their features are. This will give you an idea of why 3D printers are so expensive. So let’s start by talking about stereolithography.
Stereolithography, also known as SLA, is an original industrial 3D printing process. SLA printers work to produce high levels of detail, smooth surface finish, and products that can withstand a lot. Stereolithography is mainly used in the medical industry to create anatomical models and microfluidics. For such tasks, 3D Systems’ Viper projects and the iPro 3D printer model are considered better. The next type of 3D printer is Selective Laser Sintering, or SLS. In Selective Laser Sintering, solid plastic and nylon-based powders are melted together. Because parts made from SLS are made of real thermoplastic material, they are strong and durable, suitable for tough testing and easy to fit due to their flexibility.
The EP 140 3D printer is considered suitable for this work. Another type of 3D printing process is PolyJet PolyJet technology allows you to produce production with different materials and colors. If you are making a single model and using strong plastic material, then you should choose Selective Laser Sintering or SLS. This is more economical. But if you are making prototypes using overmolding or silicone rubber design, then PolyJet technology can save you money. This speeds up the prototype development cycle.
The next type of 3D printer is Digital Light Processing, or DLP. DLP is quite similar to stereolithography, but instead of a digital light projector screen, UV lasers are used in SL. This means that DLP printers can build all layers at once, making the model ready quickly. This process is suitable for low-volume production and uses plastic parts. In addition to these, there is also MultiJet Fusion and Fused Deposition Modeling technology for 3D printing.
Let’s talk about metal 3D printing processes. You heard that right. There is also Direct Metal Laser Printing. This means that metal is melted and shaped. Direct Metal Laser Printing is a technology used to design metal parts, also known as DMLS, meaning that metal parts are made using metal 3D printing. New possibilities have emerged with DMLS. The advantage of DMLS is that it uses less metal. It is easy to design internal channels for making lightweight parts. DMLS is capable of both prototyping and production. DMLS is also beneficial for the medical industry because it is suitable for complicated IIE. That’s not the only 3D printing process. Another one is Electron Beam Melting, or EBM. In this process, electron beams are used, controlled by electromagnetic coils.
Electron beams melt metal powder, which is then used to create necessary prototypes and designs. The temperature inside depends on how much metal is used. Currently, the United States is the world leader in this 3D printing technology, with the largest installed base of 3D printers in the US alone generating 35% of global additive manufacturing revenue in 2020. After the US, the UK has become a good base for using 3D printers, and every day, investment in 3D printing technology is increasing here. After the UK, Germany has also become aware of 3D printing technology. It was 24% in 2016 and reached 81% in 2019. The country leads in the medical sector, and the government also has good support. So far, we have read or heard that 3D printers are being used to make tools, components, limbs, skeletons, and even toys.
But now, a company called Cell Bricks is engaged in making human organs using 3D printing technology, which will be used for organ transplants. Because there is a shortage of organ donors worldwide, the shortage of organs is always there. Lutz Kloke, founder of Cell Bricks, says that whoever needs an organ will go to the lab, where their body cells will be taken, and they will be grown in the lab. Bricks will gradually build structures, and organ development will be done from there. There is also a bio 3D printer in Cell Bricks’ lab where tissues are made. However, some experts also say that Cell Bricks’ effort is good, but it is still in the research stage, and it is a bit difficult to attract investors now. So 3D printing technology is a multidimensional technology, and there is still much work to be done, but it’s true that it has changed the perspective of manufacturing technology.

Why 3D printing is vital to success of US manufacturing
Your 3D printer is building layer by layer, lap by lap, going around, constructing the structure. So instead of cutting something away, you’re actually adding something up. I don’t think Michelangelo could fathom a 3D printer. If you want innovation in the United States, you’ll need manufacturing in the United States. Digital manufacturing accelerates innovation, no question. Right now, we need to create more machines because the demand is insane. We’ve got to return to our roots, and our roots are our manufacturers and doers.
It’s a simple logical process, but it represents a revolution far beyond the wildest dreams of 18th-century man. Manufacturing in America used to be a loud, dirty, messy business. But this is not your grandfather’s factory. We’re going to explore additive manufacturing, previously known as 3D printing, and see what it means for the American economy, the workforce, and the future of supply chains. The 3D printing market is forecast to triple in size to $44.5 billion between 2022 and 2026.
I believe that as economies become less global and somewhat more local, technologies like this will change the way we think about manufacturing. I think we may be about to enter a new golden age of technological investment and innovation. That’s because legacy industries like manufacturing, transport, logistics, and healthcare are all ripe for technological innovation.
Additive manufacturing is already used in various industries, from art to automotive to aerospace. After all, why would you have complex supply chains if you can make components on-site, building precision parts quickly and reliably layer by layer?
We start our journey at Xometry, based outside Washington, DC. It’s a great example of how technology can shake up traditional manufacturing. One thing that always amazes me is how many machines and how few people there are in modern factories. We’ve got all these 3D printing manufacturers in our marketplace, and they’re running 24 hours a day, literally, because these machines are largely automated. Entrepreneur Randy Altschuler saw a chance to use the “long tail of the internet” to link buyers to all kinds of manufacturers in a way that hadn’t been done before.
And there are all sorts of opportunities for people to sell their goods via the internet. That wasn’t true in manufacturing. Even in boom times when manufacturing is seemingly exploding, we always have 20 percent excess capacity right here in the United States. So we can tap into that capacity at any given time. The idea was to use the Xometry platform to optimize access, price, and lead times for customers while also giving manufacturers an opportunity to fill excess capacity.
There are hundreds of thousands of small manufacturers in the United States; there’s over 600,000. And 75 percent of them have fewer than 20 employees. These are local mom-and-pop manufacturers that historically have depended completely on their local customers. They have limited sales and marketing budgets. Maybe they have a website, maybe none at all. Xometry is primarily an online manufacturing marketplace, and 3D printing is still only a small part of that marketplace. But they do have their own additive facilities. In this machine, they’re making a custom part in polycarbonate for a major automotive company. Over here, a Darth Vader mask. Tell us a little bit about what’s happening in one of the machines.
In 3D printing, you’re actually adding up material to produce something, so the waste is minimal. And it enables you to achieve geometries that aren’t possible in traditional manufacturing. So in this case, you’ve got a nozzle that’s extruding two different kinds of plastic material to produce this part. And so a customer has created a 3D CAD file, basically an electronic schematic of what they want with all the details, and the software is interacting with the machine to give the instructions for the nozzle to extrude the plastic in a way to produce that part. You can’t imagine that being cut on a traditional machine. Very different from the old-fashioned manufacturing you usually think about.
There’s something else about localized manufacturing and 3D printing in particular: it’s nimble. Parts can be made fast, and designs can be changed fast. In fact, the same machine can make all kinds of different parts. This is what you’d usually consider a desktop 3D printer. So this is something that I may have at my own shop in my house to make some parts. In this case, we’re printing PLA, which is a low-temperature material used for rapid prototyping. And Xometry’s platform, this is a low-cost, quick way to get your shape. Do you remember when you went from a film camera to a digital camera? I can now, at low cost and high speeds, iterate my design before it’s a product and work out some kinks very early in that, just like you could with a digital camera, picking the right shot and moving forward.
And it allows me to not just develop my product faster, but develop it better. I’m curious how being able to do this speeds up the production cycle. And does it allow you to innovate more quickly? Absolutely. And we’re seeing that day after day. And I’ve been in this industry for about 15 years. 3D printing was just something you did. It was kind of expensive. And now it’s part of every single production. Every single product being developed, if it’s not in the thing, it’s probably used somewhere in the making of that thing. So you can increase diversity, and more people can do it, cut the supply chain, and sort of move fast, fail quickly, and innovate? Absolutely, yeah. It’s an awesome tool. Manufacturing complex parts on demand, on location, cutting out complex international supply chains.
So what’s the catch? Why hasn’t 3D printing gone more mainstream already? Well, the problem is that there are really big challenges. There’s the cost of the equipment, the challenge of integrating existing manufacturing systems with these new technologies, reliability, and also how to develop a skilled workforce. In the past, the reality hasn’t lived up to the hype. At one point, we all thought we’d be making parts at home. But that hasn’t happened. But the 3D printing industry is growing by around 20 percent year on year. And although it’s only a small fraction of overall US manufacturing, I believe that means there’s huge opportunity. And there are big rewards, too. Covid and the war in Ukraine underline the need for supply chains that are resilient, not just efficient, while the chip war with China has put the emphasis on supply chain security.
3D printing technology is incredible. It can reduce parts and lead times by as much as 90 percent, slash material costs by 90 percent, and cut energy use in half. That all helps lower the cost of making goods here in America.
Everything around us, except the food that we grow and ourselves, is manufactured. Every object that’s manufactured has an incredible story. So I like to tell my students to think about the journey of every manufactured object and use that as a vehicle to understand the fundamentals of manufacturing and the implications of manufacturing for our society.
Empowering Innovation and Prototyping:
3D printing, which has become famous for the thriving maker community who create everything from specialized dice to custom prosthetics, has grown into an industry with a global market value of 18.3 billion in 2020. In the US alone, the market size is expected to reach 3.6 billion dollars in 2023, with an anticipated annual growth of 20% for the next five years. That’s serious money.
3D printing is no longer just for rapid prototyping and custom one-offs but is becoming a legit full-scale manufacturing method since the cost of machines has become so affordable. It is feasible for businesses to operate hundreds of machines churning out production-grade parts 24/7. These newer printers have started to disrupt the manufacturing industry as they can produce some parts up to 100 times faster than conventional machining and laser processes, which, in turn, reduces costs for consumers.
Quick and affordable access to 3D printing has enabled businesses in nearly every industry to innovate through rapid prototyping and design iterations. The low cost compared to traditional manufacturing reduces the risk associated with developing new products and enables design thinking. Starting in the early 2000s, a perfect storm allowed the industry to explode. Twenty years after being issued the original design patents, they started to expire, making it fair game for everyone to use the technology. This allowed the rise of the RepRap project, an open-source initiative to create 3D printers that could print more 3D printers. This lowered the cost of entry barrier and, along with other improvements to computing, allowed anyone to innovate with 3D printing.
With so many different people working with affordable 3D printers, innovation skyrocketed, with the hobby community rapidly improving and refining the technology to be comparable, and perhaps even surpassing, commercial printers at a fraction of the cost. Some innovations from the open-source community include high-speed and multi-material printing, as well as advances in slicing software. A few organizations, such as Prusa Labs, were able to take advantage of the open-source software model and apply it to physical hardware. This combination of radical technological innovation and new business models led to architectural innovation with the creation of the consumer 3D printing industry, of which Prusa Labs is now an industry leader.
The aerospace industry is known for safety, quality, and precision, which creates a barrier to entry. This is why it is such a big deal that companies such as General Electric are investing big into 3D printing. GE’s latest turbofan engine, the GE9X, has more than 300 additive-manufactured parts, including fuel nozzles and low-pressure turbine blades, both of which are extremely difficult and expensive to manufacture with other methods. These new turbine blades are stronger and lighter than traditional blades, giving the engine a 10% fuel efficiency boost over its predecessor. Other jet engine companies have been rapidly adopting 3D printing technology to remain competitive, with early adopters such as GE.
Not to be outdone, both SpaceX and NASA have started to use 3D printing to enable innovation in space. SpaceX has experimented with 3D printed parts in their SuperDraco thrusters, while NASA has sent 3D printers into space to test the ability to print replacement parts and tools without resupply missions. This capability will reduce the uncertainty of sending astronauts off-planet without proper support and will be instrumental for long-term missions on the moon and Mars.
Back on Earth, even the medical industry isn’t immune to disruption from 3D printing. The ability to print low-cost custom-made prosthetics and other medical devices has enabled medical researchers to engage in design thinking as they look to manufacture custom tools and experiment with new styles of limb replacement. Further disruptions will occur as researchers start to print biomaterials, particularly in the organ donation area. In the future, perhaps instead of relying on organ donations, 3D printing may cause an architectural change by printing organs using a person’s own cells, which could lower the risk of rejection or the need for lifetime immunosuppressive medications.
Another great example is the hearing aid industry, which transitioned to nearly 100% 3D printed hearing aids in just 500 days. Custom-fit, made-to-order hearing aids are produced in a single day thanks to SLA technology. Hearing aid businesses that failed to make the transition were driven out of the industry, as the 3D printed hearing aids are more comfortable, cheaper, and produced much faster than the original methods.
One unexpected area that could be subject to disruption is the housing industry. Increasing weather volatility due to climate change resulting in more extreme weather events combined with skilled labor shortages and other external factors may create new opportunities for 3D printed housing. Already being used in Mexico to create houses for low-income workers, these homes could disrupt low-cost or disaster relief housing due to the high speed and low cost needed to create the homes. When combined with the ecological advantages of less waste, these homes can provide a diffusion entry point for further development.
Who hasn’t dreamed of having a Star Trek replicator in their house, where you could step up and order anything? While still in its infancy and only being used in molecular kitchens or fancy bakeries, 3D printing of food offers the first step towards this dream. While it is unlikely to revolutionize restaurants or the takeout industry anytime soon, it does have a chance to create radical innovation in space exploration by providing tastier meals with more variety on long-term missions to Mars and beyond. It also has the potential to create positive disruption in the nutrition industry by lowering the cost and producing healthier, more nutritious food for everyone. Who doesn’t want a seven-layer cheesecake on demand, especially if it’s healthy?
3D printing is poised to revolutionize manufacturing in nearly all industries. The capabilities enable new business models such as make-to-order, crowdsourcing, and open-source design. The technology can produce faster, better, and customized products. Printing can be done nearly anywhere and frees companies and individuals from costly tooling and manufacturing facilities. I don’t know about you, but I’m very excited to see where 3D printing takes us and how it will continue to disrupt many aspects of our lives.
What 3D Bioprinting Is and How It Works
3D bioprinting, also known as bioprinting, is a relatively new technology that, in theory, would allow humans to fabricate nearly any tissue or organ from scratch. The fundamental idea behind bioprinting is quite similar to that of ordinary 3D printing, in which a material, usually plastic, is printed one layer at a time. However, instead of plastic, bioprinters use bioink, usually composed of cells suspended in a special gel known as a hydrogel, which helps to protect, nourish, and hold the cells together.
Some bioinks use a single type of cells, while others contain multiple types of cells, or multiple bioinks are used side by side, each with a different cell type. There are three categories of bioprinting that I will be discussing here, which differentiate in the method by which they turn the bioink into a specific shape. Note that due to the fact that this is an emerging technology, the exact name and classification of various methods vary from source to source. The concepts, however, are universal. I choose to group the various bioprinting methods into the following categories: extrusion-based bioprinting, droplet-based bioprinting, and energy-based bioprinting.
Extrusion-based bioprinting is similar to what most people would think of when they think of conventional 3D printers. It involves forcing continuous filaments of a material through a nozzle in a controlled manner to create a 3D structure. The material is bioink, which, as I said before, usually consists of cells and a hydrogel. The filaments are forced through a nozzle by either pneumatic pressure, which is basically air pressure, or mechanically derived pressure, which comes from things like pistons or screws. The bioink must be stabilized quickly or else it will not retain its shape. The bioink can be stabilized in a number of ways, largely depending on the hydrogel that is being used. For example, during printing, the bioink can be stabilized by spraying a mist with a cross-linking agent dissolved in it. By the way, cross-linking just means linking one polymer chain to another, and this is done to stabilize the bioink.
In contrast, droplet-based bioprinting deposits discrete volumes or droplets of bioink onto a surface. Droplet-based bioprinting methods include inkjet-based bioprinting, micro-valve-based bioprinting, and laser-induced forward transfer bioprinting. As with extrusion-based bioprinting, the bioink must be quickly stabilized in order for the structure to retain its shape, and the exact manner in which this is accomplished depends on the hydrogel being used.
Inkjet-based bioprinting shares a lot in common with traditional inkjet printing. Here’s how it works at a high level: a pulse of pressure is used to eject a droplet of bioink.
The pulse of pressure can be generated in one of two ways:
using thermal mechanisms or piezoelectric mechanisms. In the thermal mechanism, a small surface of the bioink is heated and vaporized to create a bubble, which occupies a larger space than the liquid bioink did, creating pressure forcing a droplet of bioink out of the nozzle. Once the bubble collapses, a bit of bioink is sucked from the reservoir, refilling the chamber, and the process is repeated. In the piezoelectric mechanism, an electric current is applied to a piezoelectric actuator, causing the chamber to deform slightly, forcing a droplet of bioink out of the nozzle. By the way, a piezoelectric actuator is a device that responds to an electric current by stretching and bending. Then, when the electric current to the piezoelectric actuator ceases, the shape returns to normal, and a bit of bioink is sucked from the reservoir, refilling the chamber, and the process is repeated.
Micro-valve-based bioprinting involves small valves that can be accurately opened and closed with electromagnets to deposit droplets of bioink, which is under pressure, usually pneumatic pressure, meaning air pressure. Laser-induced forward transfer bioprinting uses lasers to accurately position cells on a substrate or the place where the tissue will lie. Laser-induced forward transfer bioprinting consists of a laser, a focus lens, a ribbon, and a substrate. The ribbon could contain a sheet of transparent quartz glass with a very thin gold coating and a coating of bioink. When the laser reaches the gold, it heats it and greatly expands it, propelling a very small amount of bioink to the substrate, which will have been coated with hydrogel to dampen the kinetic energy of the droplet of bioink. This laser is quite precise, and hence, this method is also quite precise.
Finally, in energy-based bioprinting, a focused energy source, often a laser, is used to selectively solidify or stabilize a bioink. This method differs from extrusion-based bioprinting and droplet-based bioprinting in that the bioink is already in place. Perhaps the most notable method of energy-based bioprinting is stereolithography. In stereolithography, a laser is employed to selectively harden a small amount of bioink, which contains a light-sensitive hydrogel. This substance lies on a platform that is then moved away from the laser by a small amount. If in doing so, the platform is immersed into bioink, then a fresh coat of bioink will flow on top of the now hardened layer of bioink. Or, if the platform has side walls, then a fresh layer of bioink can be coated separately. This process is repeated, eventually leaving you with a solid 3D structure once the liquid bioink is washed away.
Each category of bioprinting has its own pros and cons. I won’t bore you with all the specifics; however, as an example, laser-induced forward transfer bioprinting is precise and has a high printing resolution. Nevertheless, it is expensive, cumbersome, and time-consuming. Hence, different methods are used for different needs.
Interestingly, there are approaches being developed that combine different bioprinting methods in order to maximize efficiency. Maximizing efficiency is crucial for bioprinting certain structures, like organs. In general, organs must be printed quite quickly, and yet they have certain parts that contain lots of details that consequently require bioprinting with a high resolution. Other parts don’t need to be printed with such precision, and time can be saved by not printing at such a high resolution. So, by combining certain methods that print slowly with a high resolution with those that print quickly with a lower resolution, one can optimize the bioprinting process.
While these bioprinting methods are based on 3D printing, living things develop and change over time. Hence, bioprinting can often be thought of as 4D bioprinting, where the cells in the printed tissue proliferate, interact, and change in various ways over time. In fact, certain chemicals are often added to the bioink to influence the behavior and development of cells. Also, over time, hydrogel is meant to slowly degrade and be replaced by the native extracellular matrix. The extracellular matrix is the non-living material that cells secrete, which fills the spaces between cells, protects cells, and holds. home
