With a heat deflection temperature of 140°C straight out of the machine, 3D parts printed in EnvisionTEC’s HTM140 mold material can be directly vulcanized in rubber, eliminating the need for a metal master. The high-temperature material is designed to withstand both the heat and pressure of vulcanizing without losing dimensional stability. It also is suited for a variety of applications that require thermal resistance, such as items to be metallized or tested for hot air; hot-water applications; and for making tools for small-run injection molding.
Build time with the mold material is 1" in less than 90 min. at 35 micron resolution in Z. It is available for all the company’s Perfactory and Ultra models.
Editor PickCan Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
