Abstract

This study focuses on improving the surface quality of laser-sintered (LS) parts and mitigating the rough surface texture characteristic of the Selective Laser Sintering (SLS) process. Experiments were conducted using a 2500 HiQ 3D System, employing a fractional factorial design of experiments (DOE) with five factors at two levels. The melt flow rate (MFR) was used as an indicator of recycled powder quality, with PA 2200 powder exhibiting an MFR range of 15–20. Results reveal that surface texture is strongly affected by scan spacing and interactions among laser power, scan speed, and scanning strategy. The proposed approach offers a systematic framework for optimizing LS process parameters for recycled PA 2200 powder, enhancing surface finish and overall part quality.
