Active energy ray-curable resin composition for three-dimensional model supporting material
An object of the present invention is to provide a shape supporting support material which can be efficiently removed after molding in addition manufacturing and an active energy ray-curable resin composition used for forming the support material. An active energy ray-curable resin composition containing the ionic monomer (A), the nonionic water-soluble monomer (B), the nonpolymerizable compound (C), and the photopolymerization initiator (D), and/or the polyfunctional monomer (E) is used. The support material can be thereby efficiently removed from the formed roughly modeled product. Furthermore, a three-dimensional modeled product having a non-contaminated surface and high molding accuracy can be obtained.
