The different 3D printing processes explained: extrusion, curing, sintering, and more

There are several different processes used to create three-dimensional objects.  Let’s continue our dive into the world of 3D printing and look at the different 3D printing processes: extrusion, curing, sintering, and others.

Extrusion

Extrusion is one of the most popular 3D printing processes and this is the method that you’re likely most familiar with. It is used in Fused Deposition Modeling (FDM) printers, which are widely available and affordable, and used by most 3D printers at home. The process works by heating and extruding a filament of plastic, which is then deposited layer by layer to create an object. One of the main advantages of FDM is its low cost, as the process uses common and inexpensive filaments such as ABS and PLA. FDM is also known for its wide material compatibility and ease of use. However, one of the main disadvantages of FDM is that the printed objects may have a lower resolution and a rougher surface finish when compared to other processes.

Curing

Curing is another popular 3D printing process. It is used in Stereolithography (SLA) and Digital Light Processing (DLP) printers. The process works by curing a liquid resin with a UV light, which solidifies the resin layer by layer to create an object. SLA and DLP are known for their high resolution and precision, but they are more expensive than FDM 3D printers.  One of the main disadvantages is that the process can be more time-consuming and require more post-processing work, as the objects need to be cleaned, cured, and sanded, which naturally results in a more expensive process.

Sintering

Lasers are cool! Sintering is a type of 3D printing process that uses a laser to fuse together powdered materials to create an object, most commonly used in Selective Laser Sintering (SLS) printers. One of the main advantages is its ability to create complex geometries and print with a wide range of materials, including metals, ceramics, and even glass. However, the process can be more time-consuming and the parts may have a rougher surface finish.

Other innovative processes of 3D Printing

Other 3D printing processes include Multi Jet Fusion (MJF), Binder Jetting, and Material Jetting. These processes use different techniques and materials to build objects. MJF uses a combination of heat, pressure, and a fusing agent to fuse together a bed of powdered materials. MJF is known for its high precision and material compatibility but it is relatively new in the market. 

Binder jetting uses a liquid binder to bind together a bed of powdered materials. Binder Jetting is known for its fast printing speed and good surface quality, but it needs post-processing work. 

Material jetting uses a print head to deposit droplets of material layer by layer. Material Jetting is known for its high resolution and material compatibility, but it is relatively expensive.

As we’ve seen, there are many different 3D printing materials and processes available, such as extrusion, curing, sintering, and other processes. They all have their own advantages and disadvantages, and it's important to define the specific needs of a project before deciding on the right process.

Future Possibilities for 3D Printing

Bioprinting

3D printing technology has grown considerably over the last decade and is beginning to revolutionize a number of industries. However, there are still many potential future developments in 3D printing technology that could have even greater impact. Let’s look to the future and discuss a few of the most promising areas of development, such as bioprinting, nanoprinting, and others.

One of the most exciting areas of development in 3D printing technology is bioprinting. Bioprinting is the process of using 3D printing technology to create living tissue and organs. One of the most significant implications of bioprinting is its potential impact on the healthcare industry. The technology is already being used to create small structures such as blood vessels and heart tissue, and in the future, it is expected to be used to create entire organs, such as livers and kidneys. This could potentially alleviate the shortage of organ donors and reduce the need for organ transplants.

Nanoprinting

Another area of development in 3D printing technology is nanoprinting. Nanoprinting is the process of using 3D printing technology to create structures at the nanometer scale, and has huge potential to impact the electronics industry. The technology is already being used to create small structures such as transistors and solar cells, which could potentially lead to the creation of faster, more efficient, and more powerful electronic devices. In the future, it is expected to be used to create even smaller structures, such as DNA and proteins. Experts expect the global nanoprinting market is expected to continue its rapid growth.

Multi-Material Printing

A third area of development in 3D printing technology is multi-material printing. Multi-material printing is the process of using 3D printing technology to create structures using multiple materials at the same time. The technology is already being used to create structures using a combination of metals, plastics, and ceramics, and in the future, it is expected to be used to create structures using a wider range of materials, such as wood and glass. Multi-material printing has great potential to impact the manufacturing industry. It has the potential to revolutionize the way we create and produce things. For example, this could potentially lead to the creation of more complex and customized products.

While 3D printing technology is still in its developmental infancy (and is underutilized!), there are many potential future developments that could have even greater impact. Bioprinting, nanoprinting, and multi-material printing are some of the most promising areas of development that are expected to revolutionize how we create and produce things. Bioprinting has the potential to revolutionize healthcare, nanoprinting has the potential to revolutionize electronics, and multi-material printing has the potential to revolutionize manufacturing. As technology continues to evolve, we can expect to see more companies adopt it and create new and innovative products. These developments will likely open up new possibilities and opportunities for innovation and growth.

Ethical and regulatory considerations surrounding 3D printing 

The new innovations in 3D printing technology are exciting, but not without controversy. One of the most significant ethical questions surrounding 3D printing at home is the potential for the creation of weapons, such as guns. It is controversial that anyone with the right type of 3D printer can print a weapon, raising concerns about the safety and security of society. 

There are also concerns about the potential for 3D printed items to be used for illegal activities, such as counterfeiting or piracy. 

Additionally, the tech of Bioprinting and Nanoprinting must contend with deep philosophical dilemmas. Just because we can, does it mean we should? 

On top of that, there are legal and ethical questions to consider. Currently there is a lack of regulation surrounding bioprinting and its applications, which could lead to legal disputes over issues such as patent infringement and liability for injuries caused by bioprinted products. 

We also must consider the legal concept of intellectual property. Bioprinting technology is still in its early stages of development, and there is a risk of companies and researchers patenting biological materials, which could limit access and stifle innovation. 

What about Intellectual Property rights? There is a risk of companies and researchers patenting biological materials, which could also limit access and stifle innovation (and is quite likely already happening). 

Additionally, there are concerns about the environmental impact of 3D printing, as the materials and process used may not be sustainable. 3D Printers at home pretty much exclusively use a plastic-derived filament, and with the current controversy around microplastics, it may not be the slam dunk solution we once thought it was.

Ethical considerations of bioprinting

Bioprinting technology has the potential to revolutionize the way we create and replace living tissue and organs. This could potentially alleviate the shortage of organ donors and reduce the need for organ transplants. Bioprinting can also be used in the field of cosmetic surgery and wound healing as it can be used to create cartilage, skin, and bone tissue.

But bioprinting is not without controversy. Bioprinting involves handling living cells, which can pose risks of contamination and infection. There are also concerns about the long-term safety and efficacy of bioprinted tissues and organs. Many long-term studies need to be performed on 3D printed transplants before I’ll consider it for myself!

There are also ethical issues surrounding human tissue: Bioprinting technology could potentially be used to create human organ tissue or even whole organs. This raises ethical issues around the use of human tissue for medical research and organ replacement.

Bioprinting is not limited to human tissue, and scientists are already working on bioprinting animals, which raises additional ethical questions about the treatment of animals and the welfare of the bioprinted animals themselves. Could we theoretically bioprint a dog customized to have the exact traits we desire, and assemble it piece by piece?

Ethical considerations of nanoprinting

Nanoprinting technology has the potential to revolutionize the way we create electronic devices and circuits. As discussed earlier, the technology is already being used to create small structures such as transistors and solar cells, and in the future, it is expected to be used to create even smaller structures, such as DNA and proteins, which could potentially lead to the creation of faster, more efficient, and more powerful electronic devices.

However cool this may sound, it is not without potential controversy. There are a number of safety, environmental and societal concerns related to nanoprinting. For example, Nanoparticles can be highly reactive and potentially toxic, and there are concerns about the long-term safety and health risks associated with exposure to these materials. Imagine getting a 3D printed heart transplant that results in cancer (or an increase of microplastics in your blood). 

Environmentally speaking, the release of nanoparticles into the environment could have unintended consequences, such as pollution of air and water, and damage to ecosystems. We’ve already seen the staggering volume of microplastics everywhere but have yet to face the consequences (which are likely headed our way). 

Additionally, nanoprinting could lead to the development of new technologies and products that could have significant impact on society. It is important to consider the potential unintended consequences of these developments. 

Take the military industrial complex for example. There are valid ethical concerns surrounding the use of nanotechnology in military applications. Nanoprinting could be used to create new weapons and military technologies, which raises further ethical questions about the use of these technologies to kill people in warfare. 

There is also societal controversy surrounding the use of nanotechnology in surveillance, privacy, and human rights. The development and use of nanotechnology in areas such as could have a significant impact on civil liberties and human rights, and it is important to consider these implications.

Ethics of multi-material printing

Multi-material printing technology has the potential to revolutionize the way we create and produce things. Structures are already being printed using a combination of metals, plastics, and ceramics, and in the future, it is expected to be used to create structures using a wider range of materials, such as wood and glass. This could potentially lead to the creation of more complex and customized products. 

The use of 3D printing technology in construction can have a positive impact on the industry as it could reasonably reduce the time and cost of construction, increase precision, and open up new design possibilities. Using 3D printing in the aerospace industry can also lead to the reduction in weight and increase in strength of parts, leading to more fuel-efficient aircrafts.

However, because the market lacks regulation, people may be rightly concerned about moving into a 3D printed house. No reasonable person would want to move into a 3D printed home that has a risk of collapse. A 3D printed house must pass code enforcement inspections just like a traditional home, after all.

In the field of fashion, 3D printing technology is being used to create clothing, shoes and accessories. This could lead to a downward trend in sweatshop manufacturing. However, it could also automate people out of a job. 

Conclusion
