Title: Metal Additive Manufacturing Processes

The wide variety of metal additive manufacturing processes can be tailored to specific needs. Understanding these processes is crucial for optimizing production. Here are some key methods:

  1. Powder Bed Fusion (PBF): In PBF processes, a layer of metal powder is spread, then selectively melted using a laser or electron beam. It's widely used for complex parts.

  2. Direct Energy Deposition (DED): DED involves depositing material layer by layer, often using a nozzle. It's suitable for repairing or adding material to existing components.

  3. Binder Jetting: In this process, a liquid binder is deposited onto a powder bed. It's used for both metal and sand casting patterns.

  4. Sheet Lamination: Sheet lamination involves binding metal sheets together and cutting them to shape using a laser or other cutting tool.

  5. Material Extrusion: Similar to 3D printing, material extrusion uses a metal filament that's heated and deposited layer by layer.

  6. Directed Energy Deposition (DED): DED involves blowing metal powder into a molten pool created by a laser or electron beam, creating large parts.

  7. Wire Arc Additive Manufacturing (WAAM): WAAM utilizes an electric arc to melt metal wire and deposit it layer by layer. It's ideal for large, structurally sound components.

Title: Materials Used in Metal Additive Manufacturing
