What is PolyJet 3D Printing?
PolyJet is a 3D printing process which is used for rapid prototyping and additive manufacturing. It is a highly versatile process which offers a cost-effective and fast way to achieve aesthetically appealing prototype parts, at pre-production stage.
Did you know?
The PolyJet 3D printing process is unique among 3D printing technologies for its range of complex printers which are capable using multiple materials simultaneously to build a single part.
How does PolyJet work?
We use a Stratasys Objet 260 Connex 3 multi-material 3D Printer. The printer’s triple-jetting technology makes it possible to use a combination of materials and – as a result – a range of properties and finishes.
Small droplets of photopolymer material are sprayed on to the build platform where they are instantly cured using ultraviolet light. The part outline takes shape in layers from the platform upwards.
When should PolyJet be used?
PolyJet is ideal for 3D parts where more than one material will be required; for instance, where a layer of a part needs to be softer and more flexible than another layer. These layers can be ‘over printed’ in different materials to give a range of properties, features, thicknesses and harnesses.
Why use PolyJet?
PolyJet is a popular rapid prototyping technology. It is one of the most versatile of all the RP processes.
Used widely in the automotive, aerospace, consumer goods, electronics and medical sectors, the PolyJet process can produce highly accurate parts.
Benefits of the process include:
- Speed: Small numbers of parts can be produced quickly.
- Multi-material parts: multiple materials can be used in printing of a single part on a single job, producing a range of part properties.
- End-product match: due to the range of materials and multi-material capabilities of the process, parts can be matched precisely to the look and feel of complex products.
- Precision: ultra-thin 16-micron layer printing delivers fine detail parts with smooth surfaces, thin walls and complex shapes to 0.1 mm accuracy.
- Broad range of part properties:
- Rigid to flexible properties
- Thermal resistance
- High level of feature complexity
- Smooth surface finish
- Ultra-thin layers ideal for over printing
- Parts can be drilled and tapped, sanded and painted
What materials are available?
The PolyJet materials we use allow us to offer parts with the following properties:
- Rigid opaque
- Simulated polypropylene
- Rubber-like – Shore A 30 > 95
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.
What dispatch options are available for PolyJet parts?
We offer four dispatch levels for PolyJet parts:
- Express: dispatch next working day
- Standard: in 3 working days
- Economy: in 5 working days
- Super-Economy: in 10 working days
What finishing options are available for PolyJet parts?
PolyJet parts can be spray painted. The build supports are removed from PolyJet parts.
