PolyJet 3D is a 3D printing technology known for its customizable material properties and excellent surface finish. It works by jetting UV curable resin onto a build tray in a process that is somewhat similar to inkjet printing. PolyJet 3D printing offers one of the most advanced industrial 3D printing solutions available, producing parts with incredible precision and speed. It also supports a wide variety of build materials.

Advantages of PolyJet

Efficiency

Eliminates the multi-stage processes of traditional manufacturing, such as tooling, milling, and creating molds.

Material Selection

Offers a vast material selection with a range of properties, as well as the ability to print multiple materials and simulate overmolds.

Complex Geometry

Creates complex shapes with a high degree of precision that would otherwise be impossible to build via traditional manufacturing processes.

Rapid Turnaround

Because PolyJet 3D can create complex and multi-material parts in a single operation, significantly less build time is needed vs. traditional manufacturing. We can have parts to you in as fast as 1 day.

Rubber-like Flexibility

PolyJet 3D can build vastly different part geometries, unlike traditional processes that would necessitate a complete retooling of an assembly line to produce a different part.

Overview: What is PolyJet?

The Basics of PolyJet

PolyJet 3D is a 3D printing technology known for its customizable material properties and excellent surface finish. It works by jetting UV curable resin onto a build tray in a process somewhat similar to inkjet printing. PolyJet 3D printing offers one of the most advanced industrial 3D printing solutions available, producing parts with incredible precision and speed. It also supports a wide variety of build materials.

How PolyJet Works

PolyJet 3D printed parts are built using photopolymer liquid resin. The printer places layers of photocurable resins onto a build tray in extremely fine layers. As the layers are placed, they are simultaneously cured via exposure to an ultraviolet (UV) light, solidifying them into solid material matching the programmed CAD file. This process repeats itself layer by layer until the entire part has been constructed. In the case of parts with complex geometries, support structures are added to the part to ensure a successful build and then manually removed during the finishing process.

Benefits of PolyJet 3D Printing

PolyJet is known for its customizable material properties and excellent surface finish, creating prototypes that are both detailed and smooth. PolyJet allows manufacturers to customize material properties, and supports various photopolymer options that can simulate a variety of different end-use materials. Combined with PolyJet’s high accuracy to CAD files and it’s overmold capabilities, this manufacturing process is a favorite for rapid prototyping.
