PolyJet 3D Printing

How does PolyJet 3D Printing work:

The Polyjet (a.k.a. Multijet Modeling) technique was developed by the company Objet Geometries Ltd.. Objet was founded in 1998 by Rami Bonen, Gershon Miller and Hanan Gotaiit. After about ten years, the company presented the first multi-material 3D printer. In 2012, the first PolyJet 3D Printing system with more than 100 combined materials was introduced by Objet Ltd. In the same year, Objet merged with the industry giant Stratasys.

PolyJet 3D Printing is similar to inkjet document printing, but instead of jetting drops of ink onto paper, PolyJet 3D printers jet layers of liquid photopolymer onto a build tray and instantly cure them with UV light. The layers build up to create a precise 3D model or prototype. Along with the selected model materials, the PolyJet 3D printer also jets a gel-like support material specially designed to uphold overhangs and complicated geometries. It is easily removed by hand or water. The most advanced PolyJet system, the J750 Printer, combines diverse 3D printing materials in one model by jetting multiple materials simultaneously (in full color). This means the user can selectively position multiple materials in one printed prototype and even combine two or three materials to create composite models with distinct, predictable properties.

 


PolyJet 3D Printing Materials:

There are plenty of materials available for this technology. We offer 4 standard materials. Besides the ‘pure’ materials, it is possible to ‘blend’ materials during the print process. As an example, Tango with a shore hardness of around A25 can be mixed during the print process with traces of Vero, to create a digital material with a final shore hardness of A 50 or higher. Based on this method, soft materials can be created with a shore hardness range from ~A25 – 95.

 

VeroBlack / VeroGray / VeroBlue: Rigid, high-resolution and all-purpose plastic, one of the most popular prototyping materials


Utilizing the PolyJet process, the Vero materials have good overall properties. With an extremely high resolution layer slice (0.0006″), models have smooth contour surfaces and the appearance of production parts, with very little post-processing.  Rigid PolyJet parts are great for producing accurate, high resolution small and medium prototypes, that require the finest features and detail. Parts as small as 0.0125″ can be produced with an incredible level of detail. Ideal for accurate; visual and conceptual models. Parts created with the PolyJet process can be sanded primed and painted for presentation, or used as RTV mold masters.

Uses:

  • Bottles and Containers
  • Packaging
  • Connectors
  • Small Fine Feature Parts
  • Medical Devices and Small Housings

Advantages:

  • Opaque white parts look near production
  • Extremely high detail
  • Rigid & Durable
  • Great fine features & smooth contour curves
  • Great for molds and patterns

 

VeroClear: Transparent material that simulates PMMA


VeroClear is a transparent material that simulates PMMA (polymethyl methacrylate), commonly known as acrylic. Like PMMA, VeroClear is used as an alternative to glass and is ideal for concept modeling and design verification of clear parts such as eyewear, light covers and medical devices. It offers strength, stiffness, elongation and impact resistance, and the ability to blend with other materials for a range of opacities, hues and hardness. VeroClear enables visualization of internal components and features, and simulation of glass ideal for form and fit testing of see-through parts.

Uses:

  • Form and fit testing of see through parts, like glass consumer products, eye wear, light covers and cases
  • Visualization of liquid flow
  • Medical applications
  • Artistic and exhibition modeling

Advantages:

  • Outstanding versatility
  • Excellent fine feature detail
  • Ideal for simulating PMMA

TangoPlus / TangoBlackPlus / TangoGray: Tango and TangoPlus simulate thermoplastic elastomers with flexible, rubber-like qualities


Tango and TangoPlus simulate thermoplastic elastomers with flexible, rubber-like qualities. Ideal for testing and verifying visual, tactile and functional applications such as grips, gaskets and footwear. Tango produces soft, flexible prototypes that require shock absorption, vibration dampening or a non-slip surface. Blend Tango with other PolyJet Photopolymers for different hardness, elongation and tear resistance levels.

Uses:

  • Rubber surrounds and over molding
  • Soft-touch coatings and nonslip surfaces
  • Knobs, grips, pulls, handles, gaskets, seals, hoses and footwear
  • Exhibition and communication models

Advantages:

  • High elongation at break
  • High tensile strength
  • Outstanding versatility
  • Excellent detail visualization
  • Can combine with rigid materials to create rubber-like digital materials with varying Shore A values, colors and opacities.

 

Rigur: an advanced simulated polypropylene


Rigur, an advanced simulated polypropylene, offers durability and a smooth finish. 3D print precision prototypes that look and behave like polypropylene. Rapidly create models to test form, fit and function for snap-fit assemblies, living hinges and durable housings and packaging.

Uses:

  • Reusable containers and packaging
  • Flexible, snap-fit applications and living hinges
  • Toys, battery cases, laboratory equipment
  • Loudspeakers and automotive components

Advantages:

  • Versatility
  • Fine details
  • Superior toughness
  • Smooth surfaces
  • Print precision prototypes that look and behave like polypropylene

PolyJet 3D Printing Design Guide:

Engineers and Designers who are planning to produce PolyJet 3D Printed parts benefit greatly from the extreme design freedom that this process affords with materials like VeroBlack. Unlike traditional manufacturing processes like injection molding and CNC machining where there are limits on what features can be designed into a part due to cost, set up, or tooling restrictions. PolyJet 3D Printing is an additive manufacturing process and therefore you are only limited by your imagination and a few very basic guide lines.

Here is a link to our PolyJet 3D Printed Part Design Guide, it will offer you useful design tips for this 3D printing process  as well as answers to many frequently asked questions about about the PolyJet 3D printing process:
