Abstract

Claims (42)

1 . 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 D 50 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 D 50 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 D 50 particle size based on the value of the D 50 particle size,

wherein the powder material provides a D 100 particle size as the largest particle size of the particles, a D 10 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=D 100 −D 10 ,

wherein D is at most 21% of the D 100 .

2 . The powder material according to claim 1 ,

wherein at most 5 wt.-% of the particles provide a particle size being at least 20% higher than the D 50 particle size based on the value of the D 50 particle size.

3 . The powder material according to claim 1 ,

wherein the powder material provides a particle size distribution factor L being at least 0.08 and being at most 1.2,

wherein L is calculated according to formula (I)

L =( D 90 −D 10 )/ D 50   (I),

wherein D 50 is a particle size that 90 wt.-% of the particles are equal to or smaller, and wherein D 10 is a particle size that 10 wt.-% of the particles are equal to or smaller.

4 . The powder material according to claim 1 ,

wherein the D 50 particle size is from 16 μm to 51 μm, or

wherein at least 80 wt.-% of the powder material provides a particle size selected from 12 μm to 55 μm.

5 . The powder material according to claim 1 ,

wherein the powder material consists of at least 90 wt.-% of a metal or a metal alloy.

6 . The powder material according to claim 1 ,

wherein the powder material provides a particle size of at most 60 μm.

7 . The powder material according to claim 1 ,

wherein the powder material consists of at least 80 wt.-% of a ceramic material.

8 . The powder material according to claim 1 ,

wherein the powder material provides a particle size distribution factor L being at most 1.9,

wherein L is calculated according to formula (I)

L =( D 90 −D 10 )/ D 50   (I),

wherein D 50 is a particle size that 90 wt.-% of the particles are equal to or smaller, and wherein D 10 is a particle size that 10 wt.-% of the particles are equal to or smaller.

9 . A method of additive manufacturing, comprising:

manufacturing a product from the powder material or repairing a product utilizing the powder material according to claim 1 .

10 . The method of additive manufacturing according to claim 9 ,

wherein the additive manufacturing method utilizes a powder bed of the powder material,

wherein the method includes selective melting a part of the powder bed to manufacture or repair the product.

11 . The method of additive manufacturing according to claim 9 ,

comprising manufacturing or repairing the product via a selective laser melting additive manufacturing process or an electron beam melting additive manufacturing process.

12 . A method of additive manufacturing, comprising:

using the powder material according to claim 1 for additive manufacturing.

13 . A product manufactured from the powder material according to claim 1 .

14 . The product according to claim 13 ,

wherein the product consists of a multitude of the particles held together by a binder.

15 . A product manufactured or repaired according to the method of claim 9 .
