Process description
Although it can use a number of different materials the main use of powder bed fusion is being a convenient way to print metal parts. spreading a layer a powdered material over the entire print surface, and then selectively melting the sections that will be in the final part. another layer is then added on top of the last repeating the process until the part is completed.
strengths
weaknesses
- High energy use: melting metal takes much more energy then melting thermo plastics
- Surface finish: Powder bed fusion generally has a rough surface finish that mimics the grain size of the material
- material properties:
