Abstract

Provided is a three-dimensional modeling apparatus including a stage, a constraining body, a supply nozzle, an irradiation unit, and a movement mechanism. The constraining body includes a surface including a linear region along a first direction, and is opposed to the stage so that the linear region is the closest to the stage. The supply nozzle supplies a material curable by energy of an energy ray into a slit region between the stage and the linear region. The irradiation unit irradiates the supplied material with the energy ray through the constraining body. The movement mechanism moves the stage relative to the constraining body along a second direction for forming a cured layer of the material for one layer, and moves the constraining body and the stage relative to each other along a stacking direction for stacking the cured layers.

Description

technical field [0001] The present invention relates to a three-dimensional modeling apparatus for forming three-dimensional objects from photocurable materials, to objects formed by the apparatus, and to methods of manufacturing objects. Background technique [0002] In the past, modeling equipment for forming three-dimensional objects has been known as a rapid sample preparation equipment, and it is widely used commercially. Generally, a three-dimensional modeling apparatus forms an object layer by layer based on shape data for each predetermined thickness of the object to be modeled (ie, shape data for each layer). [0003] As one of the main methods for three-dimensional modeling devices, stereolithography is exemplified in which a photocurable resin is selectively irradiated with laser light, whereby a desired part of the resin is cured and drawn, thereby forming an object. [0004] Three-dimensional printing includes, for example, a free surface method and a constrain...
