Ink set for optical molding and manufacturing method of Photoforming article

摘要

Problem to be solved: to use a support material having excellent removal ability of the support material and a high degree of independency, and to provide an optical forming ink set for obtaining a light shaping material having good dimensional accuracy, excellent in soft strength, and excellent tensile strength, and a Photoforming material made using the photoset ink set, and Problem to be solved: to provide a method of manufacturing a Photoforming product using the Photoforming ink set.The ink set for Photoforming isComposition for model materialTG is an ethylenically unsaturated monomer (a) of 20 to 120An ethylene unsaturated monomer (b) of TG and below 65 to 20A two functional acrylate oligomer (c) of 800-10000 andInitiator (d),AndThe content of the acrylate compound more than 2 parts by weight is less than 15 parts by weight;Composition for support materialA water-soluble monofunctional ethylenic unsaturated monomer (a) of 19 to 80 mass parts and polyalkylene glycol (b) having a molecular weight of 15 to 75 mass parts containing 300-3000 oxybutylene groupsContains.Diagram
