Green-AeroSM tooling has developid a rapid toolmaking process. The company uses a vacuum-casting technique and ceramic tooling material adapted from the metal foundry industry. In addition, the master no longer limits the tooling approach—since it is removed before tool hardening it can be made from almost any material, including an FDM or SLA model, original part, or medium-density tooling foam. The tools may be washed out, even after high-temperature exposure, for trapped-tooling applications.
