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 HIPing?
HIPing, or Hot Isostatic Pressing, a post-printing process, employs a press to eliminate pores and remove defects such as nitrides, oxides and carbides, thus increasing material properties. It often combines with heat treating for safety- and quality-critical parts to increase material ductility and fatigue resistance.
