Abstract
A method of forming a component by powder bed fusion includes depositing a bed of metal powder on a platform by moving a recoater blade across the platform at a first angle of approach. A layer of the component is formed by sintering at least a portion of the bed of metal powder. A subsequent bed of metal powder is deposited on the platform by moving the recoater blade across the platform and the bed of metal powder at a second angle of approach. A subsequent layer of the component is formed by sintering at least a portion of the subsequent bed of metal powder.

A method of forming a component by powder bed fusion, wherein the method comprises:
- depositing a bed of metal powder on a platform by moving a recoater blade across the platform at a first angle of approach;
- forming a layer of the component by sintering at least a portion of the bed of metal powder;
- depositing a subsequent bed of metal powder on the platform by moving the recoater blade across the platform and the bed of metal powder at a second angle of approach, wherein the second angle of approach and the first angle of approach are not equal;
- and
- forming a subsequent layer of the component by sintering at least a portion of the subsequent bed of metal powder.
A powder bed fusion machine comprises:
- a platform;
- a recoater comprising:
- a leading edge;
- and
- an actuator configured to adjust an angle of approach of the leading edge of the recoater.
A powder bed fusion machine comprises:
- a platform comprising:
- a first edge;
- a recoater blade comprising:
- a leading edge;
- and
- at least one actuator configured to adjust an angle of approach of the leading edge of the recoater relative to the first edge of the platform.
