Abstract

The invention discloses a three-dimensional manufacturing apparatus, a three-dimensional manufactured object producing method, and a container for the three-dimensional manufacturing apparatus. Thereis provided a three-dimensional manufacturing apparatus which is characterized by comprising: a container configured to hold a liquid photocurable resin; a base configured to support a solid manufactured object obtained by curing the liquid photocurable resin; a moving unit configured to move the base; and a light source unit configured to irradiate light for curing the liquid photocurable resin.The container comprises a light transmission portion which is provided between the light source unit and the base, and is in contact with the liquid photocurable resin. The three-dimensional manufacturing apparatus further comprises a flow facilitating unit configured to facilitate a flow of the photocurable resin which is in contact with the light transmission portion, the flow being attended bythe movement of the base.

Description

technical field [0001] The present invention relates to a three-dimensional manufacturing device for manufacturing a three-dimensional manufactured object by projecting an exposure image onto a photocurable liquid resin material, a three-dimensional manufactured object manufacturing method for manufacturing a three-dimensional manufactured object, and a container for the three-dimensional manufacturing device. Background technique [0002] In recent years, expectations for so-called three-dimensional printers have been increasing. In particular, the development of devices using methods of making three-dimensional fabricated objects by projecting exposure images onto photocurable liquid resin materials is active. [0003] For example, in Japanese Patent Application Laid-Open No. H05-96632, it is disclosed that a photocurable resin solution is accommodated in a container whose upper surface is open, light is irradiated from above the free liquid surface of the photocurable res...
