Metal Laser Sintering Hybrid Milling
This metal laser sintering hybrid milling process combines metal powder 3D laser sintering with high speed milling finishing into one machining system. This process is similar to 3D printing, but using any one of several different grades of powdered metal with laser sintering to create a 3D part in metal. The system lays down a thin layer of powder, laser sinters that level in accordance to a 3D solid model, repeats that process for ten layers and then switches to a high speed mill and finish machines the ten layer stack which equals .020" thickness. It then continues the process until the complete part is finished. The laser sintering process can be controlled to create solid as well as porous sections throughout the process so the porous areas can then be used as venting areas in injection molds or medical/dental implant type parts.
