What is Post Processing?
Post Processing of metal-AM parts often is necessary to achieve the required physical and cosmetic properties, including surface quality, geometrical tolerances and mechanical properties. Post-processing steps include heat treatment, EDM or sawing to separate parts from the build plate and support structures, surface finishing by machining or abrasive grinding, and heat treatment to relieve stresses.
What is Heat Treating?
Heat Treating parts after additive manufacturing releases most internal stresses accumulated in the material during the printing phase and/or optimizes the mechanical properties of the parts.
