Overview: How PolyJet 3D Printing Works?

The Basics of PolyJet 3D Printing

PolyJet is a 3D printing technology that builds parts by jetting thousands of photopolymer droplets onto a build platform and solidifying them with a UV light. It’s one of the fastest and most accurate 3D printing technologies that produces smooth, accurate parts, prototypes and tooling.

Benefits of PolyJet 3D Printing

3D printing benefits
  • Create smooth, detailed prototypes that convey final-product aesthetics.

  • Produce accurate moulds, jigs, fixtures and other manufacturing tools.

  • Achieve complex shapes, intricate details and delicate features.

  • Incorporate the widest variety of colors and materials into a single model for unbeatable efficiency.

Features of PolyJet 3D Printing



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

Complex Geometry

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

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.

Material Selection

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

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 days.



Photopolymers are not stable over time and most resins don’t have balanced impact/heat resistance.

Scale Effect

The unit cost and lead time will not be reduced as much as casted or molded parts.

PolyJet 3D Printing Applications

With SLA, the prototype can be made using nylon material with great functionality. Fast turnaround makes it a good choice for functional prototyping.
Customized Products
The speed and versatility of SLA let variable production of customized gifts/samples for different users become possible.
Batched Products
SLA can be applied to make high-quality small batched products from 1-10,000 units, ideal for small businesses that wishes to test the market’s reaction to their newly developed products.
