文摘
- •
Laser-sintered samples are built with different machines and parameters.
- •
Tensile testing and microstructural analysis is performed.
- •
Samples show variable ductility and an anisotropic mechanical response.
- •
Outstanding ductility was back traced to distinctive microstructural features.
- •
Pores and residual particles contribute to the mechanical properties significantly.
