Abstract

A three-dimensional shaped article production method according to the invention is a method for producing a three-dimensional shaped article by stacking layers formed in a predetermined pattern, wherein a series of steps including a composition supply step of supplying a composition containing a plurality of particles to a predetermined part, and a bonding step of bonding the particles by irradiation with a laser light is performed repeatedly, and the composition supply step includes a step of forming a first region using a first composition containing first particles as the composition, and a step of forming a second region using a second composition containing second particles which are different from the first particles as the composition, and the bonding of the particles in the first region and the bonding of the particles in the second region are performed by irradiation with laser lights with a different spectrum.
