Does A 3D Printer Use Ink?

by 3Dprintingadvice

In case you have not heard about it, the innovative technology of 3D printing is the future. It can print anything from buildings to appliances.

What is not clear to those that want to use it is if it uses ink or not. Therefore, I will like you to know what a 3D printer uses to do its printing. The question here now is:

Does A 3D Printer Use Ink?

Does A 3D Printer Use Ink?

The answer is: yes it does. According to researchers, they have produced the latest kind of platform for 3D printing that can use ink. Scientists call the invention “Flink,” which means active living ink. Unlike in the past when 3D printers used plastics and powdery metals for ink, this new invention uses living bacteria.

As a result, you can now create tiny biochemical factories. You can say that the 3D ink is pumping with life due to the bacteria which it contains. In short, with this ink, a 3D printer can produce living components which can degrade toxins.

Also, these living materials can facilitate organ transplants. Moreover, the former elements used in place of ink can only produce artificial bones or super strong steel. However, they can’t produce biocompatible materials which require maximum flexibility. This particular 3D ink can print any material that is bacteria based. Also, it can print elastic based materials. Furthermore, researchers can now print any 3D structure at one run with the 3D printer ink on these materials.

However, the output you get depends on the bacteria species that the ink contains. Also, the process you follow can also help to produce the biologically needed materials. These materials can break down high-purity cellulose or toxic substances you can use in biomedical appliances. 

What is 3D Printer Ink Made Of?

The ink for the 3D printer is derived from different bacteria which offers different functions. Their function is to produce different concentrations of bacteria to enable the production of objects that have different properties. Furthermore, the structure of the ink comes from a particular biocompatible hydrogel. This specific hydrogel comprises various components. Such as: pyrogenic silica, hyaluronic acid, and long-chain sugar molecules.

What scientists do with these compounds is to mix the culture medium to help the bacteria in ink. As a result, the ink bacteria will now have all the requirements for life. Thus, when researchers use hydrogel as a base, they can now add the bacteria that have the appropriate range of properties.

With the output, you can now print any structure in 3D as you may wish. However, during the development process of the ink, the researcher should make sure that the ink is liquid enough to pass through a printer nozzle.

If not, the bacteria’s mobility will be affected. Moreover, if the ink is stiff, it will become more difficult to move them. Also, the cellulose secretion will become lesser.

On the other hand, the ink shouldn’t be too fluid. If the ink happens to be too fluid, you cannot print sturdy structures because they will collapse under pressure. It should be just strong enough to make the objects printed carry the weight of the preceding layers.

Is 3D Printer Ink Expensive?

The materials that are used for 3D printing are not the same or equal. As a result, the 3D printer ink cost may not be the same. If you are going for the regular 3D printing filaments like the ABS or PLA filament, they may not be expensive.

However, when you go in for the special inks, they may cost four times more than others. Just with every other thing you may want to buy on earth, you will havemany options. The prices also vary due to many different reasons.

You are likely to choose from the ugly, the bad, and the good. If you are still an amateur in this field, you may find it confusing. However, with proper guidance, you can find it easy. 

Tips for Choosing 3D Printer Ink

  • Big Name Brands – If you are looking for big name brands, you are likely to spend more. But if you go for the ones that are locked in brands, you can buy affordable ones. 
  • The Material Content of the Ink – The material used for the ink is also a factor in the pricing. If the materials contained in ink is more exotic, it is likely to cost more. But for lesser materials like the ABS or PLA, you can get a lower price.
  • The Colorants – If you go for the ink with little amounts of color, they are likely to be cheaper since their colors are effectively free. However, if you go in for deeper colorants, I believe they will likely come with a cost. 
  • The Packaging and Roll – How the roll of the ink or its packaging is done carries additional money. So you should check your budget and decide which one to pick.

Overall, the 3D printer ink may be on the high side in comparison to others, yet it is affordable. Moreover, with the ink, you are sure of a successful output without drawbacks or mistakes. Furthermore, the output quality will never be in question. 

Where to Buy 3D Printer Ink?

There are so many outlets where you can buy a 3D printer ink, such as Amazon.com. You can also go to the manufacturer’s page of the particular 3D printer ink you want to use. 


Traditionally a 3D printer cannot use any form of ink. They may only use solid powder or liquid ink. Even its modelling can only be achieved with plastic which it does by pushing molten plastic from a tiny nozzle. Although these compounds can print out super strong objects, they still have their limitations.

However, due to the latest innovations in technology, a 3D printer can now use ink. This is all due to the embedded bacteria. Moreover, due to the use of this ink, the application of the 3D printing has become more diverse.

A 3D inkjet printer is different from all the other printers available today. For instance, its objects are constructed in three dimensions. The model of a 3D printer is produced layer by layer. That is why the entire process is called 3D printing or rapid prototyping. The 3D inkjet printer enables a cost-effective, flexible, and fast printing.

Moreover, it allows for the creation of simple and more complex 3D structures or objects. 3D printers are used for additive manufacturing. This is a manufacturing process where the printer can print 3D structures by depositing layers upon layers. However, it will be according to the structure’s digital model.  

Furthermore, you can construct these structures right from your Computer-Aided Design data. You don’t need to look for tools to achieve this fete. The 3D inkjet printer originates from the family of technologies called SFF {Solid Freeform Fabrication}.  

With this printer, you can now construct complicated structures or objects in an economical and fast way. These structures would have been impossible to achieve in the past, but with this technology, it becomes easy.  

The most common procedure for this type of fast prototyping is to apply powders of metal, plaster, epoxy, bio-plastic, polyester, or polyurethane. All of these elements in a 3D inkjet printer is dynamic. What the 3D printer will do is to print out these materials in layers of powder and form them into a particular object.

However, the design for the structure will be according to the CAD file. Unlike other printers which are available today, are easy to operate, to install, affordable, and portable. Moreover, you can easily use this printer to create complex structures even in your home.
