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 3D printing 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 3D 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. The Technology House has the resources to manufacture 3D printed parts and prototypes with Polyjet technology for your projects.
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 3D Printing Advantages
PolyJet Best Uses
Not sure which additive manufacturing process is best for your application? See the other processes we offer (e.g., Carbon DLS, stereolithography (SLA), selective laser sintering (SLS), fused deposition modeling (FDM), HP Multi Jet Fusion (MJF)) and materials (metals, plastics/composites) to produce parts with custom finishes that are closer to production-ready.
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:

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

Most of my 30 year career has been spent finding vendors that meet my Cost, Service, and Quality requirements. The number of suppliers that can meet those criteria for a sustainable period of time are few. TTH is one of those companies. The management team at TTH is always willing to work with us to improve efficiency and offer solutions that exceed our expectations. If you are looking for a partner, not just a supplier, the team at TTH will not disappoint.

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.
Our integrated approach to design, prototyping, and production allows you to bring your concept to market faster and more cost-effectively than virtually anyone else.
