with PolyJet 3D Printing (PJ)

Get Colorful Demonstration Models and High-Fidelity Prototype Parts — Fast

Do you need to produce prototype parts that help you take your designs to the next level, with unmatched quality? Do you need to create colorful demonstration models that help explain concepts or validate a design? Or parts that combine multiple finishes – without overmolding and other expensive processes?

PolyJet 3D printing is one of the most versatile additive manufacturing technologies available today from Fathom’s industrial 3D printing service. It enables the production of highly accurate parts with different durometers, from rigid to rubber-like consistencies, multi-color, transparent and translucent materials – all in a single build. It also enables several materials to be printed simultaneously, simulating overmolding. And it can be used to build work holding jigs, forms and end-of-arm tooling where tight tolerances are a must.

How Does PolyJet 3D Printing Work?

PolyJet is photopolymer-based jetting process that distributes fine material droplets, layer-by-layer, onto a build platform. It can print multiple materials plus a support material at the same time. A flash of UV light immediately cures the material droplets.

PolyJet is known for its ability to print striking colors and ultra-fine details. By combining photopolymers in different concentrations and structures, it can simulate plastics, rubber and other materials, with textures and patterns that aren’t possible with any other 3D printing method. That enables you to create incredibly detailed prototypes and models that incorporate a variety of material properties and aesthetics.

At the end of the build process, the part is ready for use. No post-processing is required. The gel-like support material can be removed using a water jet, eliminating the need for time-consuming support structure removal.

How Polyjet 3D printing works

Applications of PolyJet 3D Printing

Rapid and Functional Prototypes // Create smooth, detailed prototypes with ultra-fine details and surface textures that simulate the aesthetics of your product.

Visual Aids and Models for Presentation // Because PolyJet 3D printing can combine different materials, colors and transparencies, it’s a favorite technology for creating detailed, realistic medical and dental models.

Complex Parts with Precise Dimensions // PolyJet has a minimum layer thickness of 16 microns. Its ability to capture tiny details with a high degree of dimensional accuracy is like nothing you’ve seen before in the world of additive manufacturing.

Manufacturing Tools // PolyJet isn’t just for printing pretty models. It can also be used to build molds, jigs and fixtures where dimensional accuracy is a key requirement.

Flexible Parts that Simulate Traditional Elastomers // PolyJet 3D printing service is perfect for printing gaskets, seals and housings – where elastomer-like characteristics are a must.

Industries where PolyJet parts are used include:

  • Medical
  • Dental
  • Consumer products

What Does PolyJet 3D Printing Make Possible?

Design Freedom // Choose from thousands of colors and hundreds of materials to bring your product ideas to life.

Simplify your Part Production // PolyJet printers have multiple print heads that can lay down multiple materials with different durometers and a support material at the same time, within a single part build. In other words, a PolyJet printed part can contain sections that are hard and soft. The effect is similar to overmolding but is less expensive and much faster.

Don’t Sweat the Details // Most 3D printing technologies deposit or sinter a layer of material at a time. In contrast, Polyjet lays down droplets of photopolymer to build your parts. The layers are incredibly thin, which means your parts can contain ultra-fine details, rendered with a fidelity and accuracy that other types of 3D printing can’t equal.

Fast Part Production // For smaller build volumes, PolyJet is a relatively fast 3D printing process. Plus, parts don’t require curing. Removal of support structures is quick and easy. You can get your parts in as little as one day!


Versatile and Fast // From prototypes and colorful models to end-use parts, Fathom’s PolyJet printing service does it all. It can print them quickly, giving you more time to design, test and perfect your designs.

Excellent Level of Detail // PolyJet can print layers as thin as 16 microns. That means parts produced using it can contain an extraordinary amount of detail and an excellent surface finish.

Support for Digital Materials // PolyJet printers can mix up to six resins, which gives designers, engineers and your industrial 3D printing service unprecedented creative opportunities to fine-tune their part designs and material characteristics.

Transparent Options // PolyJet can print transparent materials that enable the production of transparent and translucent parts.

Fast Removal of Support Material // The gel-like support material used by PolyJet is water soluble. It can be dissolved using a water jet. This eliminates the need for time-consuming post-production processes and results in a smoother part finish than some other 3D printing processes.

Strong Parts // PolyJet can produce sturdy parts that have good tensile strength.


Cost // The materials required for PolyJet printers tend to be more expensive than those for many other types of 3D printing.

Part Size Limitations // PolyJet isn’t suitable for printing larger parts.

Support Structure // Even though PolyJet uses a gel-like support structure, adding it contributes to longer total part printing times.

Not for Long-term Use // Exposure to heat, sunlight and humidity can cause photopolymers to lose some strength and durability.

What Can PolyJet be Paired With?

PolyJet is a unique technology in the additive manufacturing space. It’s unmatched in its ability to produce fast, colorful prototypes. Because it’s a photopolymer, it tends to deteriorate over time. That limits its ability to be paired with other technologies.

PolyJet is sometimes used to create work holding fixtures where precise positioning of a product being manufactured is a must. Over time, these fixtures will deteriorate. But a manufacturing engineer can easily print a new one to replace it.

PolyJet parts can be post-machined to meet specific tolerances. They can also be bonded to other assemblies, such as fiberglass panels.

Alternatives to PolyJet

If precise tolerances aren’t required, FDM and SLS are viable alternatives for creating jigs and fixtures,

SLA can be used for both functional prototypes and parts, which makes it a potential alternative to Fathom’s PolyJet printing service.

Multi-Jet Fusion (MJF) can produce complex geometries with excellent surface finishes, similar to PolyJet.

Traditional Technologies That Can Benefit from PolyJet

Many types of visual aids and models are now made by hand using clay, screen printing, labels and other time-consuming and often expensive manual techniques. These models can be produced much faster using PolyJet 3D printing. Inks are available in thousands of colors and can be controlled at the voxel level. It can also print a variety of surface textures. That means you can create sophisticated prototypes that exactly match the look and feel of your brand.

Prototype parts are made using a variety of techniques. Having a tool built to produce a handful of prototype injection molded parts could take weeks. CNC machining prototype parts requires time-consuming machine and work holding tool setups and a skilled operator. In contrast, Fathom’s PolyJet printing service can be used to print prototype parts in a matter of hours.

PolyJet Materials Available

PolyJet 3D printing uses photopolymers that can simulate different material properties ranging from rubber to rigid and transparent to opaque. Some materials are very hard and are heat resistant. Others have the feel of a rubber or elastomeric material that can flex, bend and act as a seal.

Digital materials expand the possibilities by blending two or more base resins to create thousands of material combinations. Customers can achieve full color capabilities, translucencies, Shore-A values, and other properties for maximum realism in product designs.

Case Study //
Guillermo del Toro’s

Guillermo del Toro’s creative vision for his movie, Pinocchio, required a new style of puppet fabrication. The use of stop animation required strict continuity for the mechanically-operated puppets, especially for the shapes and colors of Pinocchio’s nose, head and eyes. Fathom produced thousands of variations of these components using PolyJet and developed a workflow and quality-control process to meet the moviemaker’s unique needs.
