Container for optical stereoscopic shaping device

Abstract

The present invention provides a container which is used for an optical stereoscopic shaping device and has superior transparency, molding accuracy, and durability. The present invention pertains to acontainer for accommodating a photocurable composition (3) used in an optical stereoscopic shaping device provided with a container (2), an active energy ray irradiation device (5), and an actuator (8), the container (2) having a bottom (2') and walls, wherein the bottom (2') is provided with a first layer (X) composed of a hard resin, a second layer (Y) composed of a soft resin, and a third layer (Z) composed of a fluorine resin; the second layer (Y) is laminated on the first layer (X), and the third layer (Z) is laminated on the second layer (Y); the pencil hardness of the first layer (X) is at least 3B as measured according to JIS K 5600-5-4:1999; the hardness of the second layer (Y) is 10-90 as measured by an A durometer according to JIS K 6253-3:2012; and the thickness of the third layer is 0.1-5.0 mm.

Description

technical field [0001] The present invention relates to a container excellent in transparency, molding accuracy and durability used in an optical three-dimensional modeling device. Background technique [0002] Patent Document 1 discloses a method of supplying a necessary amount of controlled light energy to a liquid photocurable resin to cure it into a thin layer, and further supplying a liquid photocurable resin thereon, and then performing the process under control. The lamination is solidified into a thin layer by light irradiation, and the three-dimensional shape is produced by repeating the above steps, which is the so-called optical three-dimensional modeling method. Furthermore, since Patent Document 2 proposed its basic practical method, various proposals related to optical three-dimensional modeling technology have been proposed. [0003] As a typical method of optically producing three-dimensional structures, the following method is generally adopted: the liquid ...

AI Technical Summary

Problems solved by technology

[0004] However, in this lifting method, the shaped object formed on the pedestal is close to the container containing the photocurable composition, so there is a possibility of deformation of the shaped object, damage to the container, etc.

In addition, in various photocurable compositions, there is a problem of deterioration due to damage to the container due to penetration or solidification of the container.
