Hypothesis
How do recycled and reused metal powders from MS1 steel perform in DMLS 3D printing compared to virgin powders?
Conclusion
Recycled metal powders showed decreased properties compared to virgin and used powders, affecting their suitability for 3D printing.
Supporting Evidence
- The microhardness of recycled powder decreased by 39% compared to virgin powder.
- Recycled powders did not flow properly, affecting their usability in 3D printing.
- Particle size distribution was broader in recycled powders, with more smaller particles.
Takeaway
This study looked at how using recycled metal powders for 3D printing can change their quality, making them less effective than new powders.
Methodology
The study evaluated virgin, used, and recycled metal powders using various analyses including SEM, EDS, XRD, and microhardness measurements.
Limitations
The study did not assess the environmental impact of the recycling process due to lack of data.
