Abstract
A three-dimensional shaped article manufacturing apparatus is an apparatus for manufacturing a three-dimensional shaped article by laminating layers formed by discharging and curing inks including a curable resin. The apparatus includes a first discharge unit configured to discharge a substantive section-forming ink to a region that forms the three-dimensional shaped article; a second discharge unit configured to discharge a sacrificial layer-forming ink for forming a sacrificial layer to a region that is adjacent to a region that forms an outermost layer of the three-dimensional shaped article and on a surface side of the outermost layer, with the substantive section-forming ink and the sacrificial layer-forming ink both including a curing component; and a curing unit configured to cure both the substantive section-forming ink and the sacrificial layer-forming ink, a viscoelasticity of the sacrificial layer-forming ink during curing of the substantive section-forming ink being less than a viscoelasticity of the substantive section-forming ink during curing of the substantive section-forming ink.
