Embodiment Construction

[0072] Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

[0073] (first embodiment) figure 1 It is a schematic configuration diagram showing a schematic configuration of an example of a manufacturing apparatus for modeling a three-dimensional modeled object according to the first embodiment. It should be noted that the "three-dimensional shaped object" in this specification refers to an object formed into a so-called three-dimensional shaped object. For example, even a plate-shaped, so-called two-dimensional shaped object, as long as its shape has thickness in three-dimensional shapes.

[0074] Such as figure 1 As shown, the three-dimensional modeling apparatus 1000 includes: a base 10; a workbench 20 configured to be driven by the drive device 11 provided on the base 10 as a drive unit along the X, Y, and Z directions shown in the figure; and a head support The part 30 has one end fixed to the base 10, and the ot...

Abstract

A three-dimensionally shaped article and a three-dimensionally shaping method are provided. A high production rate is achieved and precision shaping of a fine shape is achieved at the same time. The three-dimensionally shaped article is formed by at least stacking a second single layer on a first single layer, wherein the first single layer includes a sintered single layer obtained by irradiating a sintering target material including a metal powder and a binder with an energy beam capable of sintering the sintering target material, and the second single layer includes the sintered single layer. The sintered single layer is formed by aggregating sintered bodies. The sintered bodies are formed by sintering by irradiating the sintering target material ejected to form a droplet shape with the energy beam. A sintered body diameter in a planar view of the sintered body is defined as Ds, a distance between sintered body centers of the sintered bodies adjacent to each other is defined as Ps, and 0.5<=Ps / Ds<1.0.

Description

technical field [0001] The invention relates to a three-dimensional modeling object and a three-dimensional modeling method. Background technique [0002] Conventionally, a method such as that shown in Patent Document 1 has been disclosed as a manufacturing method for simply molding a three-dimensional shaped object using a metal material. In the method for producing a three-dimensional shaped object disclosed in Patent Document 1, a metal paste having a metal powder, a solvent, and a thickener as raw materials is formed into a layered material layer and used. Next, the layered material layer is irradiated with a beam to form a metal sintered layer or a metal melted layer, and the sintered or melted layer is stacked by repeating formation of the material layer and beam irradiation to obtain a desired three-dimensional shape. [0003] In the method for manufacturing a three-dimensional shaped object of Patent Document 1, one of the laminated material layers constituting the ...
