Problems solved by technology

That is, even though the powder blend material maintains a high degree of uniformity during manufacturing, it is found that the component distribution of the powder blend material changes due to vibrations applied to the powder blend material during storage, transportation, and handling after manufacture, so in Decreased homogeneity and consistency of powder mix material during molding

[0042] refer to Figures 1A to 1C , to describe the three-dimensional modeling powder material package 100 as the first embodiment. The three-dimensional modeling powder material package 100 includes a three-dimensional modeling powder material 110 and a storage container 101 , wherein the three-dimensional modeling powder material is accommodated inside the storage container 101 . In this embodiment, a method of supplying the three-dimensional modeling powder material 110 while maintaining the desired mixing state during the manufacturing process of the three-dimensional modeling powder material 110 as a powder mixed material including various types of particles is described . Figures 1A to 1C The storage container 101 in the first embodiment is shown. Figure 1A The state of the storage container 101 before the three-dimensional modeling powder material 110 is filled into the storage container 101 is shown. Figure 1B A state of the storage container 101 is shown in which...

[0058] refer to Figure 2A to Figure 2C , to describe a three-dimensional modeling powder material package 100 as a second embodiment. The storage container 101 in the second embodiment has the same structure as in the first embodiment except for the configuration in which the exhaust pipe 102 and the filter 103 are not provided. Therefore, in the following, portions different from those of the first embodiment are described, and portions identical to those of the first embodiment are not described.

[0059] The difference between the three-dimensional modeling powder material package 100 between this embodiment and the first embodiment lies in the method of encapsulating the three-dimensional modeling powder material 110 in the storage container 101 . In this embodiment, the three-dimensional modeling powder material 110 is introduced into the storage container 101 in a vacuum environment and packaged. Figure 2A The state of the storage container before the three-dimension...

[0067] refer to Figures 3A to 3C , to describe a three-dimensional modeling powder material package 100 as a third embodiment. The storage container 101 in the third embodiment has the same structure as the second embodiment except for the configuration in which the oxygen absorber 120 is provided in the storage container 101 . Hereinafter, parts that are different from the second embodiment are described, and parts that are the same as the second embodiment are not described.

[0068] Figure 3A to Figure 3C A storage container 101 is shown in which an oxygen absorber 120 is arranged. Figure 3B It is shown that the storage container 101 is compressed from the upper side of the storage container 101 with mechanically supplied pressure after the three-dimensional modeling powder material 110 and the oxygen absorber 120 are enclosed in the storage container 101 while the air in the storage container 101 is exhausted. to the external state. This is the state in which the op...

Abstract

The invention relates to a three-dimensional modeling powder material packaging body and a three-dimensional modeling system. The three-dimensionally shaped powder material package includes: a three-dimensionally shaped powder material including a plurality of types of particles; and a storage container configured to accommodate the three-dimensionally shaped powder material in a compressed state inside the storage container.

Description

technical field [0001] The present invention relates to a powder material package comprising: a powder material for three-dimensional modeling (hereinafter simply referred to as "three-dimensional modeling powder material") for use in sintering or melting and solidifying the powder by emitting laser light to a predetermined portion of the powder material. materials to obtain three-dimensional objects; and containers. Background technique [0002] In these years, since a solid object can be directly formed using CAD data through a three-dimensional modeling device in an additive manufacturing process, the three-dimensional modeling device has been used in various technical fields. In particular, a three-dimensional modeling apparatus of the powder bed fusion type has attracted attention because it can form a three-dimensional object with fine members with high precision. [0003] In the three-dimensional modeling device of the powder bed fusion type disclosed in Japanese Pat...
