Abstract
A powder material for additive manufacturing providing an improved microstructure and shape of a product including particles, wherein at most 25 wt.-% of the particles provide a particle size differing more than 20% from the D50 based on the value of the D50. A method of additive manufacturing includes the step of manufacturing a product from this powder material or repairing a product utilizing this powder material.
Claims15
A powder material for additive manufacturing, comprising:
- particles, wherein the particles comprise a metal, a metal alloy, or a ceramic material;
- wherein the powder material provides a D50 particle size comprising a value representing a particle size wherein 50 wt.-% of the particles are equal to or smaller, based on volume average particle size distribution;
- wherein the D50 particle size is from 14 μm to 53 μm;
- wherein at most 25 wt.-% of the particles provide a particle size differing more than 20% from the D50 particle size based on the value of the D50 particle size,
- wherein the powder material provides a D100 particle size as the largest particle size of the particles, a D10 particle size as a particle size that 10 wt.-% of the particles are equal to or smaller, and a difference D,
- wherein the difference D=D100−D10,
- wherein D is at most 21% of the D100.
