Quick answerThe Bambu Lab H2C handles PA12, PA6-CF, PC, ASA, and most engineering filaments well. Use the Bambu Studio built-in profiles as your starting point and adjust based on your specific filament brand. Ensure the enclosure is closed and the AMS is bypassed for moisture-sensitive materials.

Quick answerDry PA12 at 80°C for 8 hours and PA6-CF for 12 hours before printing — including freshly opened spools. Use an enclosed printer, disable cooling, and print on a bed treated with PEI or glue stick. Wet Nylon and printing without enclosure are the two causes of almost every Nylon print failure.

Quick answerPC requires a 260–300°C all-metal hotend, 100°C+ heated bed, zero cooling fan, and a fully enclosed chamber. Skip any one of these and you will get warping or delamination. It is not a material for open printers.

Quick answerFor most engineering functional parts, 40–60mm/s delivers the best balance of quality and time. Surface finish, layer adhesion, and bridging all improve with slower speeds. High-speed printing (200mm/s+) makes sense for prototypes where time matters more than quality.
