Helios RGD525 HT


Helios RGD525 HT

Helios RGD525 HT combines heat resistance with exceptional dimensional stability. The material can simulate the thermal performance of engineering plastics and is ideal for testing applications such as hot-air flow or hot-water flow in pipes and faucets. Objet High Temperature material has a heat deflection temperature of 63–67 °C (145-153 °F) upon removal from the printer. Thermal post treatment in a programmable oven can increase this to 75-80 °C (167-176 °F).
