Document Type and Number:
Japanese Patent JP6958217
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a resin powder for three-dimensional modeling providing high dimensional stability, capable of forming a high density and high quality object, and suitable for PBF method.SOLUTION: A resin powder for three-dimensional modeling having resin particles is characterized by the content of 25 μm or less diameter resin particles is 4 wt.% or less with respect to the resin powder for three-dimensional modeling. The content of 32 μm or less diameter resin particles is preferably 2 wt.% or less with respect to the resin powder for three-dimensional modeling. In addition, number-based content of 2 μm or less diameter resin particles calculated from number-based particle size distribution is preferably 30 number% or less with respect to the resin powder for three-dimensional modeling.SELECTED DRAWING: Figure 1
