Abstract
A 3D modeling device that forms a 3D object includes a nozzle through which a fused material obtained by plasticizing a thermoplastic material is ejected, and a build plate for receiving the fused material ejected through the nozzle. The build plate includes a contraction prevention unit that prevents the fused material from contracting upon being cured.
