ST-130 main use is for making sacrificial 3D printed composite tools for hollow core parts like tubes, manifolds and ducts.  ST-130 is capable of autoclave cure and is typically used with a standard triangle fill pattern to promote fast dissolution, optimize build speed, and conserve material. It’s particularly advantageous for making complex hollow composite shapes, which would normally require multipiece clamshell molds that produce seams in the part. Molds made with ST-130 let you create seamless, single-piece parts in one lay-up operation. This solution provides increased ease of use, improved part yield and quality – is ideal for automotive, aerospace and sporting goods industries.
