Metal Powder Supply

Metal powders play a crucial role in metal additive manufacturing (AM), commonly known as metal 3D printing. These powders are the primary raw material used to create metal parts or components through various metal AM technologies. The selection of metal powders depends on the specific application, required properties of the final product, and the chosen printing method.

Here are some key aspects regarding metal powders for additive manufacturing:

1. Metal Powder Types: Metal powders used in AM are available in various types, including but not limited to stainless steel, aluminum, titanium, nickel alloys, cobalt-chrome alloys, copper, and precious metals like gold and silver.

2. Particle Size and Distribution: Particle size and distribution significantly influence the printing process and the final part’s characteristics. Powder particles need to be fine and consistent to ensure good flowability and uniform layer deposition during printing.

3. Purity and Quality: High-quality metal powders are essential for producing parts with desired mechanical properties and surface finish. The purity of the powder affects the final product’s integrity, strength, and resistance to defects.

4. Powder Handling and Safety: Metal powders used in AM require proper handling and safety precautions due to their fine nature, which can lead to combustibility and health hazards if not managed correctly. Handling procedures and safety measures are crucial during storage, transportation, and the printing process.

5. Specialized Powders: Some metal AM techniques demand specialized powders, such as pre-alloyed powders or powders with tailored characteristics, including improved flowability, spherical shape, or specific particle size distributions.

6. Certifications and Standards: For certain industries like aerospace or medical, metal powders used in AM must meet specific industry standards and certifications to ensure the quality, reliability, and traceability of the final parts.
