The benefits of PolyJet in prototyping
- 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
Prototype Projects offers materials capable of producing parts with the following properties:
- Rigid opaque
- 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
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.
