Article Synopsis
- The AlSi7Mg0.6 alloy is valuable in LPBF for aerospace applications due to its strain tolerance, but mechanical strength requires optimizing laser parameters like scanning speed and power.
- Research identified that laser power and scanning speed significantly affect tensile strength (122 to 394 MPa) and Young's Modulus (17 to 29 GPa), while the laser strategy has less impact.
- An optimal processing region was found using 50 µm layers with energy densities between 25 and 35 J/mm, emphasizing the need for balanced laser power and speed to produce high-quality parts, and noting that conventional heat treatment can degrade mechanical properties.
Poly(dodecano-12-lactam) (commercially known as polyamide "PA12") is one of the most resourceful materials used in the selective laser sintering (SLS) process due to its chemical and physical properties. The present work examined the influence of two SLS parameters, namely, laser power and hatch orientation, on the tensile, structural, thermal, and morphological properties of the fabricated PA12 parts. The main objective was to evaluate the suitable laser power and hatching orientation with respect to obtaining better final properties.
