High Temp Resin is designed for functional prototyping in high heat applications. Understand the technical specifications and best uses.

he most notable property of this material is its Heat Deflection Temperature, which is the temperature at which a material will deform under a specified load. For High Temp, the heat deflection temperature is 289 °C @ 0.45 MPa.

High Temp is ideal for applications requiring the part to stand up to high temperatures with minimal loading. The material has almost no flex, however, so snap fits and living hinges are not suited for printing with High Temp Resin.

Design tips

Maximum bounding box

145 × 145 × 175 mm

Minimum bounding box

X, Y,Z > 5 mm ( for separated parts)

Minimum embossed detail

0.1 mm high & wide mm thick

Minimum engraved detail

0.1 mm high & wide

Minimum unsupported wall thickness

0.6 mm

A supported wall is connected on two or more sides. An unsupported wall is one connected to other walls on less than two sides. Walls in your model should be thicker than or equal to the minimum measurements suggested to ensure your model makes it through printing and cleaning. Walls that are too thin are prone to warping in the printing processing, or may break when we remove it from the printer and clean it. Walls and wires close to or slightly above the guidelines may still be rejected based on the geometry. For example, extra long wires or walls protruding from an object may be damaged during cleaning. Our production team will communicate with you if the design is too weak with tips on how to strengthen it.

Minimum supported wall thickness

0.3 mm

Minimum supported feature size

0.6 mm

Minimum unsupported feature size

1 mm

A geometry considered a wire when its thinner in both unconnected directions than its length. When a geometry is thicker than 0.9 mm in one direction, it will fall under the wall guidelines. Wires that are under our suggested minimums are prone to breaking in the cleaning process, or warping.

Escape hole diameter

Single Escape Hole Diameter
4.0 mm
Multiple Escape Hole Diameter
2.0 mm

Hollow parts of your product are filled in with a waxy support material, which is melted out before we ship your product. If escape holes are not large enough, this wax will remain inside the product.

A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.
