摘要: A method of investment casting utilizes a pattern produced by stereolithography in which three-dimensional specimen is provided light cure ethylenically unsaturated liquid material. The composition constituted the material admixture with an inert low thermoplastic weakens when heated within mold used process to prevent thermal expansion from cracking mold.
