What procedure must a build plate undergo before it can be reused during an AM metal process?

The procedure a build plate must undergo before it can be reused during an additive manufacturing (AM) metal process is resurfacing. This is important because during AM processes, especially metal printing, materials can adhere to the build plate and cause alterations in its surface texture and flatness. Over time, warping or wear can affect the surface of the build plate, which can lead to issues with the next print's quality and accuracy.

Resurfacing ensures that the build plate maintains the appropriate surface finish and flatness required for optimal adhesion of the next layer of material during printing. It can involve grinding, polishing, or applying a new coating to restore the surface to its ideal condition.

While cooling, cleaning with solvents, and recalibrating are also important steps in the overall process, they do not specifically address the preservation of the build plate's surface integrity in the same way that resurfacing does. Cooling refers to the temperature management of the plate, cleaning with solvents deals with removing leftover material or contaminants, and recalibrating focuses on ensuring that the printing equipment is set up correctly. These steps have their place, but resurfacing directly addresses the issue of wear and surface condition that is critical for successful repeated use of a build plate in metal AM applications.
