SLS Post-Processing: A Complete Guide to Finishing Nylon 3D-Printed Parts
A raw SLS nylon part is strong but rough, grey and porous. SLS post-processing is what turns it into a finished, end-use component. This guide walks through every stage — depowdering, bead blasting, dyeing, vapour smoothing, sealing and CNC finishing — with the parameters, costs and quality trade-offs that decide whether your PA12 parts ship or get rejected. Written from production-floor experience running the indigenous SinterX Pro SLS platform in India.
