Effects Of Powder Recycling In Selective Laser Melting, Nina L. Menon
Effects Of Powder Recycling In Selective Laser Melting, Nina L. Menon
Industrial and Manufacturing Engineering
The following report analyzes 316L stainless steel powder characteristics of new powder and powder that has been used in the selective laser melting process for 40-50 builds. A literature review was done of powder characteristics, different ways flowability can be tested, and effects of recycling other types of metal powders in Additive Manufacturing. Flowability improved over 21 reuses of the titanium alloy Ti-6Al-4V and resulted in stronger printed parts. Flow of S17-4 PH steel powder was measured with a Hall flowmeter and increased significantly over the course of 10 reuses. Heavily recycled (estimated 50 reuses) 316L SS powder and brand …
