1. I am trying to print this as smooth as I can with tpu using a .6 nozzle what do you reccomend

ASSISTANT RESPONSES:
1. Yep — TPU can come out crazy smooth even with a 0.6 nozzle, but you have to lean into slow + hot + steady and avoid anything that makes the filament “fight” the extruder. Based on your screenshot (Orca/FlashPrint style slicer, Adventurer 5M, 0.6 nozzle, 0.18 layer height), here’s what I recommend for the smoothest finish possible:. ✅ Best “Super Smooth TPU” Setup (0.6 Nozzle) Layer Height - 0.24mm (best smooth/fast balance for 0.6) - If you want *maximum* detail/smoothness: - 0.18mm is fine (what you’re using) - If you want “rubber factory look” smooth sides: - 0.28mm also prints really clean with 0.6 (fewer layer transitions) ✅ I’d run 0.24mm for the nicest overall.. ✅ Walls (This matters MOST for surface fin…

EXTRACTED KNOWLEDGE / HOW-TO
- --
- 0.24mm (best smooth/fast balance for 0.6)
- If you want *maximum* detail/smoothness:
- 0.18mm is fine (what you’re using)
- If you want “rubber factory look” smooth sides:
- 0.28mm also prints really clean with 0.6 (fewer layer transitions)
- 20–25 mm/s (TPU likes slow outer walls)
- 3 walls is perfect (you already have this ✅)
