Selective laser sintering (SLS) printing is the core technology for 3D printing in various industries. However, the surface finish of SLS prints is often uneven and rough, making it difficult to satisfy the aesthetic quality and functional requirements of a product. Improving surface roughness is essential for functional parts and industries with strict appearance requirements. In this study, the surface roughness of the SLS output was improved using a bead blasting post-processing method capable of large-capacity post-processing regardless of shape, and an experiment was conducted with blasting pressure and duration as the process variables. Surface roughness was measured, and the influence of the process variables was analyzed using analysis of variance and an interaction plot. The results of the experiment confirmed that the surface roughness improvement rate was up to 61% under 4 bar and 30 min post-treatment conditions.
