METHOD FOR PRODUCING FLAME-RETARDANT ADDITIVELY MANUFACTURED PRODUCT AND FLAME-RETARDANT ADDITIVELY MANUFACTURED PRODUCT

WIPO Patent Application WO/2024/048380

A1

The purpose of the present invention is to provide a method for producing a flame-retardant additively manufactured product having excellent flame retardancy and a flame-retardant additively manufactured product obtained by said method.　The present invention is a method for producing a flame-retardant additively manufactured product that includes a step that forms a flame-retardant additively manufactured product by fused deposition modeling, wherein the resin composition is a flame-retardant resin composition containing component (B): a thermoplastic resin and component (C): a phosphorus flame retardant, and the step that forms the flame-retardant additively manufactured product includes a lamination step that performs additive manufacturing under conditions where N and L satisfy formula (I), when the discharge nozzle diameter of the 3D additive manufacturing device used in fused deposition modeling is taken to be N (mm) and the lamination pitch in fused deposition modeling is taken to be L (mm).　2.4
