Three-dimensional modeling head and three-dimensional modeling device
According to an embodiment, a three-dimensional modeling head includes a heat insulating member, a light emitter, a cylindrical member, and a light absorbing member. The heat insulating member has a sealed space therein with a curved wall surface that reflects light. The light emitter emits light and has at least a light emitting face provided in the sealed space. The cylindrical member is placed to extend through the heat insulating member via the sealed space and is long in a first direction in which thermoplastic resin is ejected. The light absorbing member adsorbs light and is provided in contact with at least part of the cylindrical member in the sealed space and in an area of the sealed space containing a focusing position on which at least part of light emitted by the light emitter and reflected by the wall surface is focused.
