Until recently, hollow-build stereolithography (SL) software has been restricted primarily to making investment-casting patterns. A software module, TetraShell from DSM Somos, Elgin, Ill., lets users build structurally stronger parts with varying skin thicknesses. Users construct parts using patented TetraLattice supports from the Milwaukee School of Engineering.

Varying skin thickness reduces overall part mass, thereby reducing the amount of material needed. The technology reduces the density of metal-clad composite structures and large, light thick-sectioned parts. TetraShell works with Materialise’s Magics software and can be used on all current SL equipment.
