METHOD FOR PRODUCING THREE-DIMENSIONAL MODEL AND MODELING MATERIAL

WIPO Patent Application WO/2017/130685

A1

The purpose of the present invention is to provide a method for easily and surely producing a three-dimensional model, said three-dimensional model comprising polyurethane, polyurethane urea or polyurea as a main component, using a 3D printer. The method according to the present invention for producing a three-dimensional model, whereby a three-dimensional model comprising polyurethane, polyurethane urea or polyurea as a main component is produced using an ink-jet type 3D printer, comprises a step for successively laminating on a substrate synthetic resin layers by jetting a first liquid composition and a second liquid composition which react with each other upon mixing, said method being characterized in that, in the successive lamination step, the first liquid composition and the second liquid composition are mixed together immediately before or immediately after jetting so that the first liquid composition reacts with the second liquid composition by a pseudo-prepolymer method. The ratio by mass of the jet amount of the first liquid composition to the jet amount of the second liquid composition preferably ranges from 100:250 to 100:40 inclusive.
