Recoating device for additive manufacturing

1. A recoating device for an additive manufacturing process, the device comprising:

a recoating member for guiding a volume of material to a target area;

a support structure on which the recoating member is mounted;

a recoater base coupled with the support structure; and

at least one biasing component coupled between the recoater base and the support structure;

wherein the recoating device is configured such that the recoating member moves in a first direction along a longitude of the target area and wherein the at least one biasing component is configured to move the recoating member in a second direction different to the first direction.

2. A recoating device according to claim 1 , wherein the recoating member moves in the second direction when the recoating member pivots about an axis along the first direction.

3. A recoating device according to claim 1 , wherein the recoating member moves in the second direction when the recoating member pivots about an axis transverse to the first direction.

4. A recoating device according to claim 1 , further comprising at least one biasing component located at each end of the support structure and coupled between the recoater base and the support structure.

5. A recoating device according to claim 1 , wherein the at least one biasing component is a compression spring.

6. A recoating device according to claim 1 , further comprising at least one adjustable fixing component at each end of the support structure, the at least one adjustable fixing component each being coupled between the recoater base and the support structure.

7. A recoating device according to claim 6 , wherein a height of the recoating member in relation to the target area is adjustable by the at least one fixing component.

8. A recoating device according to claim 6 , wherein the at least one fixing component is a height adjustment screw.

9. A recoating device according to claim 6 , wherein one end of the recoating member is raised or lowered independently to another end of the recoating member.

10. A recoating device according to claim 1 , wherein the recoating member is a recoater bulb or a recoater blade.

11. A recoating device according to claim 1 , further comprising a plurality of longitudinal rails, wherein the recoating member is movable along the plurality of longitudinal rails in the first direction.

12. A recoating device according to claim 1 , further comprising:

a recoating member holder coupled with the recoater base; and

a recoating member clamp coupled with the recoater member holder;

wherein edges of the recoating member are fixed between the recoating member holder and the recoating member clamp.

13. A recoating device according to claim 12 , wherein the recoating member clamp is detachable from the recoating member holder, and optionally by the removal of one or more screws.

14. A recoating device according to claim 12 , wherein the recoating member clamp is mounted onto the recoating member holder using a hinge, wherein the hinge is operable by the removal of one or more screws.

15. A recoater device according to claim 1 , wherein the recoater member comprises rubber or plastic.

16. A three dimensional (3D) printer comprising the recoating device of claim 1 .

17. A method of manufacturing a recoating device for an additive manufacturing process, the method comprising:

forming a recoating member for guiding a volume of material to a target area;

forming a support structure on which the recoating member is mounted;

forming a recoater base coupled with the support structure; and

forming at least one biasing component coupled between the recoater base and the support structure;

wherein the recoating member moves in a first direction along a longitude of the target area and wherein the at least one biasing component is configured to move the recoating member in a second direction different to the first direction.
