Three-dimensional modeling system and three-dimensional modeling device

Abstract

The invention provides a three-dimensional modeling system and a three-dimensional modeling device, and aims to reduce post-processing steps after forming a three-dimensional modeling object. The three-dimensional molding system has a three-dimensional molding device and a heating device independent of the three-dimensional molding device, and is provided with: a first discharge unit that discharges a constituent material containing constituent material particles for forming a three-dimensional molded object in a continuous body form onto a stage; and a second ejection unit that ejects, in a continuous form, a support part forming material containing support part forming particles for forming a support part for supporting the three-dimensional molded object onto the stage. The three-dimensional modeling device repeatedly performs the formation of a constituent layer formed from a constituent material discharged from a first discharge part and the formation of a support layer formed from a support part forming material discharged from a second discharge part, thereby forming a laminated body including a plurality of constituent layers and a plurality of support layers. The heating device heats the laminate at a temperature that is higher than or equal to the sintering temperature of the constituent material particles and lower than the sintering temperature of the support part forming particles.

Description

[0001] This application is a divisional application of a patent application with an application date of October 11, 2016, an application number of 201610887166.9, and an invention title of "Fluidity Composition Group and Fluidity Composition", the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a fluid composition group and a fluid composition used when forming three-dimensional objects. Background technique [0003] Conventionally, various methods have been used to manufacture three-dimensional figures. Among them, a method of forming a three-dimensional shape using a fluid composition is disclosed. [0004] For example, Patent Document 1 discloses a method of forming a layer using a metal paste as a fluid composition, irradiating a corresponding region of a three-dimensional shaped object with laser light, and simultaneously sintering or melting the three-dimensional shaped object to produce the three...

Problems solved by technology

[0005] However, if the corresponding region of the three-dimensional model is sintered or melted while the three-dimensional model is produced, due to the heat during sintering or melting, the part other than the corresponding region of the three-dimensional model will also be sintered or melted, sometimes resulting in When placing a three-dimensional model, the load of separation operation and molding operation after removal increases.

That is, the existing manufacturing method for manufacturing three-dimensional objects cannot sufficiently reduce the post-processing steps of the manufactured three-dimensional objects
