I'm getting a few parts printed (SLA) for a pick and place machine in Nylon 12 (PA 2200) and I was hoping someone can tell me if printed threads are a viable option. Thread size is mostly M3 with the exception of M4 and M5 in a few places. I specifically want to know if the threads hold good over time and since this is a machine, there'll be plenty of vibrations and transient mechanical stresses though not on the threads directly. Load on the parts being held with the threads is also not a lot. Just a few NEMA 8 motors and a tiny camera. Any insight would be appreciated! https://reprap.org/forum/read.php?184,876049,876049#msg-876049 Sun, 14 Jun 2026 06:25:45 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?184,876049,876049#msg-876049 https://reprap.org/forum/read.php?184,876049,876049#msg-876049 electrophile Polymer Working Group Thu, 13 Aug 2020 00:34:19 -0400
