JLC's Zhuhai additive manufacturing facility (visited by Naomi Wu on 2021-11-14) will be integrated into jlcpcb.com next month to let customers order PCBs with professional closures. The SLA bay runs ~20–30 machines with ultrasonic cleaning (~3 minutes) and UV curing (~4–5 minutes); MJF parts use powder reclamation and media blasting to achieve fine, smooth surfaces.
