DRY STEREOLITHOGRAPHY

Abstract

Dry stereolithography is a new and patented process that uses thermoplastic photopolymers in film or sheet/plate form instead of liquid photopolymer resins and does not require support structures during the build process. The process generally relates to the use of dry photopolymers to make a 3D printed object formed from individually and selectively exposed dry photopolymer layers of the same or gradually varying shape. Suggested markets for dry stereolithography are outlined. Photopolymer plates/sheets/films as raw materials are environmentally friendly.
