MODELING DEVICE AND OPTICAL HEAD UNIT

A modeling device comprises a stage; a restriction body; a light irradiation unit; and a movement mechanism. The stage has a stage surface. The restriction body has a surface including a restriction surface that faces the stage surface, and a photocatalyst layer provided on the restriction surface. The restriction body restricts, with the restriction surface thereof, a position in the layering direction of a material constituting a model formed on the stage surface. The light irradiation unit irradiates the material with light via the photocatalyst layer of the restriction body. The movement mechanism moves the stage and the restriction body relative to each other. 一种成型装置包括工作台、调节主体、光照射部和移动机构。所述工作台具有台面。所述调节主体具有表面和光催化剂层，所述表面包括面向台面的调节面，所述光催化剂层布置在所述调节面上。调节主体通过所述调节面调节待形成在所述台面上的成型物的材料在层叠方向上的位置。所述光照射部经由所述调节主体的所述光催化剂层对所述材料照射光。所述移动机构使所述工作台和所述调节主体相对移动。
