A new white epoxy-acrylate stereolithography (SL) material is said to combine easy processability with robust, ABS-like properties and long-term durability.
A new white epoxy-acrylate stereolithography (SL) material is said to combine easy processability with robust, ABS-like properties and long-term durability. Developed by Huntsman Advanced Materials, East Lansing, Mich., RenShape SL 7585 photopolymer is suited for building accurate master models and prototypes, including parts with snap-fit closures, on all solid-state SL equipment. This resin is formulated to release bubbles before processing, which increases throughput. It also changes color from clear amber to white as it is exposed to laser light. Fully cured properties include a Shore hardness of 84D, tensile strength around 8000 psi, and notched Izod impact strength of 0.68 ft-lb/in.
