About Heat Resistant Plastic

Heat Resistant Plastic can simulate the thermal performance of engineering plastics, combining heat resistance with precision and a beautiful surface finish.

This material enables you to test form, fit as well as thermal function at 63–67 C (145-153 F) upon removal from the printer and at 75-80 C (167-176 F) after thermal post treatment. Thanks to the heat resistance, it’s also recommended for exhibition models that need to endure strong lighting conditions.

Example parts

Heat Resistant Plastic

Strengths

Design rules to remember when printing with Heat Resistant Plastic

SLS design rule: Embossed and engraved details

Embossed and engraved details

Recommended: 0.5 mm

For embossed and engraved details, we recommend a minimum line thickness of 0.5 mm and a depth of 0.5 mm.

Tip: if you are putting text on your design, use a bold sans-serif font for readability, such as Arial Bold.

SLS design rule: Minimum detail size

Minimum detail size

Recommended: 0.2 mm

PolyJet is one of the 3D Printing processes with the highest accuracy; up to 0.2 mm is enough to create clearly visible details.

SLS design rule: Minimum feature size

Minimum feature size

1 MM

Thin wires or unsupported features have to be at least 1 mm thick, as the material requires post-processing where smaller features could break.

SLS design rule: Moving or interlocking parts

Moving or interlocking parts

Recommended: 0.4 mm clearance between parts

A powerful feature of PolyJet is that you can have moving and interlocking parts printed in one session. With that said, we recommend keeping a minimum space of 0.4 mm between each of the designed surfaces.

SLS design rule: Wall thickness

Wall thickness

Recommended: 1 mm

The model's wall must be thick enough to support the model. We recommend working with a wall thickness of 1.0 mm or more for larger objects.

SLS design rule: Water soluble supports

Water soluble supports

PolyJet printers use a water soluble support structure specially designed to support complicated geometries during the print process. It leaves no residue and does not influence the visual properties of the final print.

Heat Resistant Plastic is printed using PolyJet technology

PolyJet 3D printing is similar to inkjet printing, but instead of jetting drops of ink onto paper, these 3D printers jet layers of liquid photopolymer onto a build tray and cure them instantly using UV light. The results are fully cured objects that can be handled and used immediately.

Using 16-micron – that’s thinner than a human hair! – layers, you can produce functional prototypes with astonishingly fine details and precision, making PolyJet your ideal choice for realistic prototypes, as well as form, fit, and functional testing. Choose from a full range of materials and incorporate a wide variety of color and material properties into your designs.
