Photostereolithographic process.

摘要

A method of generating three-dimensional objects comprising applying light of wavelength 450-550 nm by a stereolithographic technique to a photopolymerisable resin composition comprising: (a) a compound having at least one polymerisable unsaturated bond per molecule and a free radical photoinitiator, and/or (b) a compound capable of cationic polymerisation and a cationic photoinitiator, said photopolymerisable resin composition also containing a compound of which the wavelength of maximum absorption is in the range 400-600 nm. m
