Soft recoater blade and method of detecting wear
A system including a powder bed recoater blade, defining a longitudinal axis, for spreading powder of a powder bed including at least one wire interior thereof.
1. A system comprising:
a powder bed recoater blade, defining a longitudinal axis, for spreading powder of a powder bed including at least one wire interior thereof, wherein the wire extends parallel to the longitudinal axis, wherein the wire is off center within the blade, and wherein the wire is within the bottom half of the blade.
2. The system of claim 1 , wherein the wire is connected to a controller for notifying of blade geometry changes.
3. The system of claim 2 , wherein the controller is configured to signal when the wire is contacted.
4. The system of claim 2 , wherein the controller is configured to signal when physical characteristics of the wire have changed.
5. The system of claim 1 , further comprising a powder bed below the recoater blade containing a powdered material.
6. The system of claim 1 , wherein the at least one wire includes a series of parallel wires.
7. The system of claim 6 , wherein the at least one wire includes a series of parallel wires spaced apart in the vertical direction.
8. The system of claim 1 , wherein the wire includes a conductive material.
9. The system of claim 1 , wherein the wire is between 1 mm and 2 mm, inclusive.
10. The system of claim 6 , wherein each of the wires is between 0.1 mm and 2 mm, inclusive.
11. The system of claim 1 , wherein the recoater blade is part a system for an additive manufacturing.
