PolyJet

Create smooth, highly accurate parts in a wide range of materials with PolyJet 3D printing.

PolyJet Technology

PolyJet, short for Polymer Jetting, is an inkjet process for 3D printing and was created by Objet Geometries around 1998. In 2011, Objet merged with Stratasys. Also known as Objet, PolyJet creates smooth and accurate parts because the PolyJet process is one where very small layer sizes are printed. The PolyJet process also offers the widest range of materials (from rigid to elastic). There are even materials that specialize in printing rapid molds and tools that are typically good for 10-100 parts depending on size, geometry, and molding material.

Most PolyJet parts are used for fit and function prototypes, over-mold samples, full multi-colored marketing models, and medical models. Movie effects, medical models, consumer goods, automotive and electronic components are industries that typically use PolyJet parts.


PolyJet 3D Printing Process

Polyjet Digital ABS

Polyjet works by simultaneously jetting drops of photopolymer materials that solidify when exposed to UV light. This is repeated in microscopic layers over and over until the part and build are complete. Multiple materials and/or colors can be jetted at the same time to create multi-material printed parts or multi-colored printed parts. The end result is a solid 3D model.

PolyJet Advantages

  • Highly accurate with fine details
  • Smooth finish
  • Ease of use
  • Multi-Materials (ex. Over-mold Samples)
  • Multi-Colored
  • Economy of scale

PolyJet Best Uses

  • Design checks
  • Rapid tooling
  • Full color marketing models
  • Full color figurines
  • Medical models
  • Over-molded samples

PolyJet Materials

PolyJet 3D printing materials offer some of the widest range of material offerings. Materials range in durometer from 20A elastic to 90D rigid, can be printed in full-color models as well as high temperatures. Here are some of the most popular materials:

  • Digital ABS (ABS-like)
  • Vero (rigid multi-color)
  • Durus (PP-like)
  • Tango (rubber-like)
  • Rigur (PP-like)
  • High Temperature

Polyjet Printer

PolyJet 3D printing has been around for over 20 years and has evolved to larger build platforms, up to 20” x 15” x 8” (500mm x 380mm x 200mm) while building in finer build layers of 0.00055”, which allows for greater detail, accuracy and finish. Some machines can print up to 6 different materials (elastic or rigid, opaque or clear) at once to create prototypes in multiple colors, different textures, transparencies and durometers.

PolyJet Design and Build Guidelines

Each 3D printing technology is a little different, here are standard guidelines to consider when choosing PolyJet as your 3D printing process:

  • Build Layers = 0.00118” to 0.00055”
  • Minimum Wall Thickness & Feature Size = 0.030”
  • Standard Finish = Level 1 Support Removal Finish (see more available custom finishes)
  • Standard Lead Time = 3-5 days
  • Tolerances = +/- 0.005” for first inch then +/- 0.002” per inch thereafter
  • Inserts = Install in post-processing with adhesives or press-fit
  • Holes = Build holes and threads into model for print and chase or ream in finishing

What Our Partners Are Saying

I have partnered closely with TTH for over a year, and working with them has been a wonderful experience. Their entire team is always pleasant to work with, their project managers are incredibly knowledgeable, and their attention to quality and timeliness is best in class. I simply cannot recommend them highly enough for any project big or small.

Design Without Restriction

See how we partnered with Vitamix and Carbon to redefine what's possible. We took a legacy, six-piece, injection-molded part design and turned it into a new, one-piece, 3D-printed part.
