ST-130 Soluble Tooling

ST-130 is a soluble tooling material engineered for sacrificial composite tooling. Print a closed-cell mandrel, lay carbon fiber over it, cure the part, and dissolve the mandrel out in a detergent wash tank, returning a hollow composite part impossible to produce with traditional molding.
