embodiment 1
[0030]FIG. 1 illustrates a configuration of a three dimensional manufacturing apparatus for manufacturing a three dimensional manufactured product as a sectional structure, in embodiment 1. In FIG. 1, a light curing resin 1 in a molten (uncured) state is housed in a container 5. In the present description, a liquid light curing resin in a molten (uncured) state is described as a light curing resin.
[0031]As the light curing resin 1, a well-known light curing resin can be used. The light curing resin can include a monomer or an oligomer, a photopolymerization initiator, and various additives (a stabilizer, a filler, a pigment and the like). Further, both a monomer and an oligomer may be included. Monomers are organic materials that are polymerized into large molecules to form plastics. Oligomers are obtained by reacting some of monomers in advance and are materials that are polymerized into large molecules to form plastics similarly to monomers. A light polymerization initiator absorb...
embodiment 2
[0071]In embodiment 1, the configuration is illustrated, in which light irradiation for curing the light curing resin is performed from below the container 5, and the manufacturing stage 3 is moved upward by the lifting / lowering apparatus 4 for each layer formation as illustrated in FIG. 1, FIG. 2 and the like. However, the direction of light irradiation for curing the light curing resin 1, and the moving direction of the manufacturing stage 3 are not necessarily limited to the directions as described above.
[0072]For example, as illustrated in FIG. 3, in a configuration in which light irradiation for curing the light curing resin 1 is performed from above the container 5, and the manufacturing stage 3 is moved downward by the lifting / lowering apparatus 4 for each layer formation, a configuration is conceivable, in which an equivalent operation and effect to the operation and effect of embodiment 1 are exhibited.
[0073]A manufacturing apparatus illustrated in FIG. 3 includes respectiv...
