Abstract
Provided is a filament for three-dimensional molding with which three-dimensional molding with fused filament fabrication is possible. Provided are a three-dimensional molded article using the filament for three-dimensional molding and a method for producing the same. The filament for three-dimensional molding contains a polyacetal resin, wherein a difference between a melting point Tm2 and a crystallization temperature Tc (Tm2−Tc) measured by a differential scanning calorimeter is 22° C. or higher and 40° C. or lower, and a melt flow rate measured at a temperature of 190° C. and a load of 2.16 kg is 0.8 g/10 min. or more and 8.0 g/10 min. or less.
