Surface finishing and inspection, sometimes referred to as post-processing, describes a family of activities generally developed to optimize surface roughness/smoothness and ensure conformance with design specifications. Below, we outline some of the post-processing capabilities available to you via 3Diigent.
This is the process of accelerating particles of abrasive material through a nozzle or centrifugal wheel to remove surface roughness. Blasting can be done with sand, steel shot, or glass beads.
Sanding is the process of rubbing a gritty paper against the surface of a part to smooth out surface roughness. The fineness of the sand establishes the "grit" level. Lower grit levels (e.g., 80, 120) are used to smooth rougher surfaces, while higher grit levels (180, 240) are used to make fairly smooth surfaces smoother.
Through and electrolytic or electroless process, a layer of copper-nickel molecules can be attached to the surface of a part. This process adds a metallic appearance and some metallic properties to a part that may have originally been printed, machined, or cast in another material. The plating can be adjusted to include more copper (for electromagnetic interference) or nickel (for strength and hardness)
Hot Isostatic Pressing, or HIPing for short, is the process of putting your parts into a high temperature pressurized container. Doing so effectively removes internal porosity from parts, typically diminishing strength properties but improving cycle time
