Build complex, hollow composite parts faster with ST-130 model material, ST-130_S support material and optimized tips. ST-130 simplifies the production of hollow composite parts. Complex tools can be 3D printed and easily dissolved after curing, eliminating secondary processes like mold making, while accelerating your composite lay-up work. Engineered and tested specifically for sacrificial tooling, ST-130 withstands the heat and pressure of autoclave curing. And it 3D prints with a permeable triangle fill pattern to cut build time, conserve material, and dissolve quickly. ST-130 model material and ST-130_S support material work with Fortus 450mc and Fortus 900mc.
