Title:
POLYMERIZABLE COMPOSITION AND METHOD FOR PRODUCING THREE-DIMENSIONAL MODELED OBJECT
Document Type and Number:
WIPO Patent Application WO/2019/203134
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a polymerizable composition which enables the production of a three-dimensional modeled object having an excellent flame retardancy.
The polymerizable composition (10) according to the present invention, which is to be used for producing a three-dimensional modeled object, comprises a photopolymerizable compound in a liquid state, a flame retardant and a flame retardant protector. The method for producing a three-dimensional modeled object is characterized by comprising steps (a) to (c): (a) a step for supplying oxygen into a modeling tank (20) in which the polymerizable composition (10) is contained through an oxygen-permeable and active energy ray-permeable base material (21); (b) a step for curing the polymerizable composition (10) by irradiating an active energy ray, said active energy ray having permeated through a buffer area (11) in which curing of the polymerizable composition (10) is inhibited by oxygen, selectively to a curing area (12) in which the oxygen concentration is lower and thus the polymerizable composition (10) can be cured; and (c) a step for continuously irradiating the active energy ray while moving the cured polymerizable composition (10) and thus three-dimensionally and continuously shaping a modeled object formed of the cured polymerizable composition.
