Material: LS Nylons
Part is cleaned of all excess powders using light brushes and compressed air along with medium grit sanding pads. Any semi-cured material is removed and sanded with progressively finer grit sandpaper
- Remove supports & excess powder
- Light Sand with 220 – 320 grit
Material: DMLS metals
Upon build completion, parts still attached to the build tray are first placed into an oven where they will endure a one-hour stress relief bake. Parts are then removed from the build tray, and the remaining support structure left on the part is removed from the part. Temperature at which part is stress relieved and the duration the part is stress relieved depends on the material used to make the part.
Part is then finished with hand tools, grinders, and polishing wheels and tools to remove support structure and bring surface quality to a 180 – 320 RMA or better depending on the surface.
If any post machining or EDM is required, or critical tolerances are required to be met, the finish level would fall into this category. A drawing may be required if any of these requirements are needed.
