Heat Deflection Temperature
HSHT fiberglass has a heat deflection temperature of 150° C (302° F).
HSHT is 29x more impact resistant than ABS and more than 100x more impact resistant than PLA.
HSHT fiberglass has the ability to deflect nearly twice as much as carbon fiber and return to its original shape when unloaded.
HSHT-reinforced Onyx, PLA, and ABS are each heated to 300 F. Unlike typical 3D printed parts, Onyx reinforced with HSHT fiberglass material retains its rigidity.
When To 3D Print With HSHT Fiberglass Material
With superior heat resistance and a flexural strength that is second only to carbon fiber, HSHT fiberglass is ideal for applications requiring high heat and impact resistance or high elasticity.
- Welding fixtures
- Thermoset molds
- Mold inserts
Humanetics, a supplier of crash test dummies, 3D prints long-lasting, cost-effective thermoset molds with HSHT fiberglass-reinforced Onyx. Printing the mold on a Markforged X7 offers reliable tooling with massive cost savings: it is 100x less expensive and 5x times faster than traditional methods.
