What is Polyjet 3D printing?

Polyjet 3D printing is a versatile process that produces accurate, high-resolution parts in a vast range of materials.

The process laminates UV curing resin layers down to 16 micron layers thick, creating complex geometries from functional, purpose-designed materials.

For a project that needs smooth and accurate parts in a short time frame, Polyjet is a top contender. It is a powerful 3D printing technology that produces parts with multiple materials in the same piece for prototypes and tooling through resin deposition – jetting a photopolymer onto a platform and solidifying it with UV light. It’s one of the most accurate 3D printing technologies, and it’s one that IPF has been utilising since 2004.

How does Polyjet 3D printing work?

The PolyJet printers themselves consist of a material reservoir, a build platform with an elevator, and a carriage on which UV lights and jetting print heads are mounted. First, photopolymer resin is moved through the reservoir to be heated so it reaches the desired viscosity. Then the carriage moves across the X-axis, above the build platform. As it moves, the print heads build up the layers of resin by selectively and accurately jetting resin, in droplets, onto the build platform. Immediately, they are cured and solidified by the UV lights. After a single layer is completed, the build platform moves down one layer in height to do the next one, and so on.

What are the benefits of Polyjet Printing?

PolyJet 3D printers can be made to work with different materials, including bio-compatible, flexible, and transparent resins. With its multiple print heads, this technology has the added advantage of being able to use multiple materials at once within a single build or part. For instance, You can combine rigid and flexible materials within the same part where you need overmoulds, seals, gaskets and non-slip surfaces, or with a part needing supports, the support material can be built up at the same time as the main material.

Materials range in performance and can be from 30 Shore A to 85 Shore D hardness. Overhanging areas use a jelly-like support material that is jetwashed away post-print. This leaves no visible support marks and allows for very complex geometries.

  • Combine multiple materials within the same part
  • High-quality surface finish
  • High precision components with complex geometry
  • Extensive multi-material, rigid/flexible, combinations (and multicoloured) to mimic overmould products
  • Intricate details
  • Medical approved materials
  • Soluble, ‘no witness’, support material
