24.09.2015· Processing optimization was pursued through SiC powder blending, infiltration with and without SiC nano powder loading, and integration of nanofibers into the powder bed. The second approach was laminated object manufacturing (LOM) in which fiber prepregs and laminates are cut to shape by a laser and stacked to form the desired part.
The Metal 3D Printing Guide - 3Dnatives
Another major metal 3D printing technology is Direct Energy Deposition (DED), similar to FDM. This method involves construction of metal parts through a CLAD laser. During the process, powder is projected by the nozzle, and fuses at the outlet through a laser beam to weld together.

Direct Metal Printing-ODM | 3D Systems
Direct Metal Printing (DMP), also commonly known as Direct Metal Laser Sintering (DMLS), is an additive manufacturing technology that builds high quality complex metal parts from 3D CAD data. In the machine, a high precision laser is directed to metal powder particles to selectively build up thin horizontal metal layers one after the other.
GC - Green Silicon Carbide. GC (green silicon carbide) is a very high-purity silicon carbide (SiC) lapping powder produced by reacting silica and coke in an electric furnace at a temperature greater than 2000° C. This process produces the following qualities: An α‑type corundum crystal configuration; A hardness just below diamond

According to the company, producing AM components for industrial use requires four essential elements: understanding of the raw materials (metal powder); process knowledge to decide which AM technology to use (for example selective laser sintering, powder bed or laser metal deposition); manufacturing expertise to produce the component itself; and finally the ability to certify or qualify the
Metal 3D Printing: An Overview of the Most …
30.08.2019· Metal 3D printing is considered the apex of all 3D printing. When it comes to strength and durability, there’s nothing quite like metal. The first patent for metal 3D printing was DMLS (direct metal laser sintering) and it was filed in the 1990s by the German company EOS. Ever since then, engineers have come up with other methods for printing with metal, some of which are entirely unique and
