Ultracur3D® ST

High Impact
Reactive Urethane Photopolymer

Ultracur3D® ST

Ultracur3D® ST (high impact product line) is a medium-viscous, highly reactive photopolymer for 3D printing applications resulting in tough multipurpose parts. It can be used to produce high performance functional parts by using stereolithography (SLA), digital light processing (DLP) or liquid crystal display (LCD) machines. Ultracur3D® ST has been designed to fulfil even the highest demands regarding accuracy, precision of details and mechanical strength. Where existing 3D printing materials often reach their limitations, our Ultracur3D® ST product line comes into play.
