Abstract
A method of producing a three-dimensional shaped article includes a step of forming particle layers by arranging particles containing a material for forming a shaped article and particles containing a material having higher solubility in fluid than the material for forming the shaped article, a step of forming a stack by melting and stacking the particle layers, and a step of removing the material having higher solubility in the fluid than the material for forming the shaped article from the stack by dissolving the material having higher solubility in the fluid than the material for forming the shaped article in the fluid.
Claims10
A method of producing a three-dimensional shaped article made of an article material, the method comprising:
- forming layers including a region made of the article material and a region made of a support material;
- forming a stack by melting and stacking the layers;
- and
- removing the region made of the support material from the stack,
- wherein the support material contains a first material having a dynamic viscoelasticity higher than a dynamic viscoelasticity of the article material and a second material having a dynamic viscoelasticity lower than the dynamic viscoelasticity of the article material, and
- wherein a difference between a dynamic viscoelasticity of the support material and the dynamic viscoelasticity of the article material is smaller than a difference between the dynamic viscoelasticity of the first material and the dynamic viscoelasticity of the article material and is smaller than a difference between the dynamic viscoelasticity of the second material and the dynamic viscoelasticity of the article material.
