Somos® TetraShell™

DSM Somos TetraShell software converts solid 3D design files into lightweight, hollow models that can be 3D printed using stereolithography to create high-quality patterns for investment casting or lost wax casting. As well as being well suited for creating prototypes, these 3D-printed patterns are ideal for tool validation and for casting small series of metal components.

Why work with Materialise Manufacturing?

Pairing TetraShell software with Materialise's stereolithography expertise lets you create high-quality, 3D-printed patterns for your investment casting or lost wax casting projects, eliminating the need for time-consuming and expensive tool production. With our patented Mammoth printers, you can even print patterns up to two meters long in a single build, reducing the risk of surface flaws.
