Photosensitive compositions useful in three-dimensional part-building and having improved photospeed

摘要

A method useful for stereolithography that yields enhanced photospeed, as well as a photocurable polymer composition well adapted for use with same, are disclosed. A preferred combination includes 1,2-dimethoxy-2-phenyl acetophenone, benzophenone, and triphenyl phosphine combined with a polyurethane (meth)acrylate oligomer.
