February-June 2021
Traditional Selective Laser Sintering (SLS) for metal is an expensive and complex process. The FDM approach brings technical and budget affordability but needs to be refined for consistent mechanical properties of the printed parts.
Approach
- FDM using polymer loaded with metallic particles and later sintered in an oven.
- Characterizing the anisotropy of the printed parts for different layer orientations with tensile testing.
Experiments
- Tensile testing on a universal testing machine.
- Computer vision to track the layer's behavior.
Results
- Anisotropy due to the print layer orientation.
- Limited elongation due to porosities resulting from the sintering process.
