What Makes PolyJet a Smart Choice for 3D Printing?

Benefits of PolyJet

The benefits of PolyJet in prototyping

PolyJet is a 3D printing technology which is used in the prototyping and additive manufacturing of parts, tools assemblies and components which:

  • Have physical or mechanical properties requiring the use of more than one material in a single build
  • Must be hard enough to be drilled or tapped
  • Need aesthetic finishing, for instance smoothing and painting

With high accuracy and microscopic layer resolution, it can produce complex geometries and thin walls using a broad range of materials.

At Prototype Projects, PolyJet services are offered alongside our other 3D printing processes – SLA, SLS and FDM. We use a Stratasys Objet 260 Connex 3 multi-material 3D Printer.

Its triple-jetting technology allows us to combine materials and – as a result – to achieve a range of properties and finishes.

What is PolyJet used for?

PolyJet is an ideal 3D printing choice where more than one material will be used one over another, in a technique known as overprinting.

With many material combinations to choose from, PolyJet allows the design engineer to integrate a wide range of material aesthetics and properties such as opacity, colour and flexibility into a part or assembly.

In general, PolyJet can be used to produce:

  • Small runs of prototypes and production parts quickly and cost effectively
  • Parts and components which combine several different materials
  • Presentation parts where end-finish quality and aesthetics are very important, and which may require sanding and painting
  • Precision parts to 0.1mm accuracy where fine detail is required
  • Ultra-thin layers, down to 16-micron thickness, ideal for over printing
  • Geometrically complex parts and components
  • Parts needing drilling or tapping

Polyjet Materials

Prototype Projects offers materials capable of producing parts with the following properties:

  • Rigid opaque
  • Transparent
  • Simulated polypropylene
  • Rubber-like – Shore A 27 > 95
  • Thermal resistance
  • Surface finish smoothness

Each part is manufactured with either a primary material or a primary and secondary material.

Where two materials are used, they are mixed to generate different levels of tensile strength, elasticity, flexural strength and temperature durability.

Example uses of PolyJet include:

  • Fittings and valves
  • Electronic components and connectors
  • Electronic packaging
  • Master patterns
  • Form and fit models
  • Realistic anatomical models
  • Presentation models
  • Flexible, rubber-like models
  • Medical devices
  • Automotive parts

Final thoughts

Overall, as a 3D printing technology for prototyping and additive manufacturing, PolyJet offers a versatile range of options for designers of parts which will be made of multiple materials with challenging physical or mechanical properties and intricate geometric characteristics.

It represents a good choice for designers working on concept models and parts with a range of flexibilities, from rubber-like products to rigid assemblies, and parts where fine details, textures and features are required.
