Title:
多様な硬化機構を有する材料からのポリウレタン三次元物体製造方法
Document Type and Number:
Japanese Patent JP6720092
Kind Code:
B2
Abstract:
A method of forming a three-dimensional object using CLIP (continuous liquid interface printing) is carried out by (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling said build region with a polymerizable liquid, said polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component (e.g.., a second reactive component) and is different from said first component (e.g., that does not contain a cationic photoinitiator, or is further solidified by a different physical mechanism, or further reacted, polymerized or chain extended by a different chemical reaction) in particular an epoxy resin precursor; (c) irradiating said build region with light through said optically transparent member to form a solid polymer scaffold from said first component and also advancing said carrier away from said build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, said three-dimensional object and containing said second solidifiable component (e.g., a second reactive component) carried in said scaffold in unsolidified and/or uncured form; and (d) concurrently with or subsequent to said irradiating step, solidifying and/or curing (e.g., further reacting, further polymerizing, further chain extending), said second solidifiable component (e.g., said second reactive component) in the three-dimensional intermediate to form said three-dimensional object.
