3D Printing With Sacrificial Tooling Material

ST-130 simplifies the production of hollow composite parts as complex tools can be 3D printed and easily dissolved after curing, eliminating the need for secondary processes like mold making.


3D printing with ST-130 produces prototypes that are able to withstand the heat and pressure of autoclave curing with material that is engineered and tested specifically for sacrificial tooling. Use ST-130 to accelerate the development and production of composite structures as it prints with a permeable triangle fill pattern designed to optimize build speed, conserve material, and dissolve quickly.
