What Is Polyjet 3D Printing Technology?

polyjet 3d printing technology
Polyjet is a term for 'polymer jet setting,' a 3D printing approach based on the jetting principle. In 2000 Objet-Geometries created the first 3D printer that used this technology, owning the patent for Polyjet.
In 2011 Stratasys obtained Objet-Geometries. Stratasys has since used the term PolyJet for the range of content jetting 3D printers. Many manufacturers of 3D printers, including 3D Technologies, do have printers which use jetting engineering. Such machines are not labeled PolyJet, because the term is held by Stratasys.

Working Of Polyjet 3d Printing Technology

PolyJet follows the very same general concept as 3D printers for jetting content. Various jetting points are now at the heart of this engineering that transmit carefully controlled flows of a photopolymer to the build plate.

The polyjet 3d printing process is also very much easy to use. With the help of polyjet 3d printing materials, it can be used easily. Photopolymers are a category of plastic resin which has aspects of a liquid basis. Whenever a photopolymer is subjected to illumination it changes its material characteristics. In the situation of photopolymer resins used during 3D printing, UV exposure allows the liquid resin to toughen. The degree to which this curing process is achieved will depend on the nature of the UV light behind it and the duration of the resin’s exposure to UV radiation.

There are also a number of polyjet 3d printing advantages. As other 3D printing methods, polyjet 3d printing technology begins with a 3d object that is printed using a slicer program. The jetting faces therefore replicate every level generated by slicer software as they convey the photopolymer content. Even the carriage upon which jetting points are mounted includes an assortment of Ultraviolet radiation which treat the photopolymer material layers when they reach the build platform. If a layer’s processing is complete, the build platform pulls away from the jetting points to enable the next surface to print. This method is replicated until after replication of the entire template.

Applications of Polyjet 3D Printing Technology

The success of polyjet 3d printing technology may be distant from that of other 3d printing techniques such as FDM or SLA. It has, nevertheless, built a reputation in industries that respect the unparalleled amount of precision and flexibility offered by the platform. The below are some of PolyJet’s most high-profile 3D printing implementations:

The polyjet 3d printing cost is very less. The polyjet 3d printing process is also very much easy to use. PolyJet 3D printing technology is most widely used in fast manufacturing. While it is possible to use almost any 3D printing technique to build models, PolyJet is the chosen process for those who emphasize precision and amount of sophistication.
PolyJet’s multi-material versatility also ensures it can produce designs which are more practical in nature. Designs with rigid parts and adjustable joints would no more have to be designed individually with PolyJet. PolyJet 3d printing materials are also outstanding choices for design models used in the production of architectures and products. PolyJet not only maintains a greater amount of detail from the 3D models, but its items are also more physically pleasing without any need for time-consuming and laborious completion.
In the healthcare field, 3D printing is also used to construct realistic versions of 3D images of the vital organs of persons. This helps physicians and other clinical personnel identify and treat patients. Since PolyJet printers are so accurate, even these 3D printed prototypes can be used to design surgical techniques.
One of PolyJet 3D printing’s most unique uses in the healthcare sector is for the development of dental molds. Doctors used plaster-based material in the old days to make molds in a method that takes a lot of expertise, is time-consuming and leads in an often uncomfortable patient satisfaction.
Doctors will also use a mixture of 3D modelling and PolyJet printing to make the surgical molds much simpler and faster. It can also be claimed that prototypes tested in 3D are more realistic than models made using a more old-fashioned techniques. These molds will help doctors build their clients with more accurate crowns, caps, and brackets without requiring them to hurt too much.
As per the availability of suitable components, PolyJet is among the most flexible 3D printing methods. There are the normal 3D printing materials such as ABS or PP and there are also rubber-like, translucent, high-temperature and econ-compatible products. With the correct array of materials, 3D printing equipment and instructional supports are available and are completely suitable for use by children.

Pros and Cons of Polyjet 3D Printing Technology

The polyjet 3d printing process is very much uncommon and mainly found in certain environments which are mainly professional. The polyjet 3d printing cost is also much higher than the normal 3d printing and 3d printers. Still there are certain polyjet 3d printing advantages and disadvantages associated with it.


Excellent Detail

The incredibly fine jetting heads used in PolyJet 3D printers ensure excellent precision. Inside PolyJet ‘s capacities, specifics as small as 16 microns or 0.016 millimeters. This level of precision is in comparison with laser-based 3D printing technologies such as Selective Laser Sintering ( SLS). The precise precision of PolyJet is higher, by at most a whole percentage, relative to FDM and SLA.

Provides options for multiple colors

The photopolymer resin which is expelled by the jetting heads is deposited in capsules somewhere within the system. A PolyJet 3D printer includes a huge amount of jet points and can be connected to various cartridges by different classes. This implies that, despite needing to make time-consuming tool adjustments, a simple print may be produced of various photopolymer products or colors.The most apparent advantage of this is that it ensures you can pretty quickly create multicolored designs with a PolyJet 3D printer. This is something that is not feasible with SLA or SLS technologies, and permissible in FDM only to a restricted extent.

Great Selection of Materials

Stratasys has continued to grow a magnificently wide variety of suitable raw resources considering the extremely advanced design of the photopolymer content used in PolyJet 3D printers. For now there are over 100 different PolyJet substances like ABS, PC, and Nylon varieties among many others.


Requiring Support Structures

Unlike powder-based printing processes, where a template has elongated characteristics, PolyJet would involve the incorporation of support systems. That just doesn’t take a lot of time as most slicer apps will do this seamlessly for you. It requires a large amount of material though and improves the time required to complete processing a given 3D pattern.

Photopolymer Resin Vulnerable to Light and Heat Degradation

Photopolymers are susceptible to either light or heat type, by nature. Also liable for the natural degradation of photopolymers is just the same process which converts liquid resin to solid plastic. This implies items manufactured with PolyJet manufacturing are not intended for long-term use particularly in outdoor environments. This property also questions the appropriateness of PolyJet prints for designs which are supposed to have durable or practical characteristics. They can be solid when rendered freshly, however over period these physical properties can become weakened.

Buying Guide

  • Know the thing before printing: Always make sure to have a clear idea about what you are printing. This is one of the biggest considerations of buying a 3D printer.
  • Good features: The printer that you will be buying should have proper features. There must be best as well as safety features available.
  • Proper resolution: The 3D printer that you are buying should have proper resolution. That is very much important for good quality printing.
  • Price: Price is also an important factor. A number of options are available in the market and they all fall within a great affordable range.
