Dear Team,
I’m experiencing severe warping issues with Bambulab’s PA6-GF filament, regardless of the settings used.
Setup:
Printer: P1S with AMS, 2 weeks old, fully calibrated, factory settings.
Room temperature: 21°C.
Plates: Textured and Smooth Plate from Bambulab, using adhesive (3D-Lac spray).
Nozzle: 0.4 mm hardened steel.
Extruder gears: Currently stainless steel, with a hardened steel set available but not yet installed.
Slicer: Bambu Studio, latest version.
Settings: Using AMS system with the automatically detected filament profile for PA6-GF. Speed reduced (≤100 mm/s), bed temperature 100°C. Cooling fans set to a maximum of 10%, as defined in the profile, and I have confirmed the fans are working properly.
Infill: Tested with 10% (reduced) and 15% (default) using Gyroid and standard infill patterns.
Filament preparation: Dried in a filament dryer for 9 hours at 65°C before use.
Problem:
The model warps severely, especially at the corners and across the surface, regardless of the print size. For example, the Benchy detached from the plate mid-print and fell off, with the filament continuing to extrude into the air (see attached photo). My nearly new print plates, including an unused Smooth Plate, offered no adhesion even with glue.
Despite 4–5 attempts using different settings, the issue persists. Other materials like PLA, ABS, and ASA print flawlessly under the same conditions, leading me to suspect a problem with the filament itself.
I would appreciate your assistance.
Best regards,
Patrick
