I haven’t been able to find any published settings for AzureFilm Hyper Speed PETG on the A1, and the manufacturer currently doesn’t offer an A1 profile either. In my opinion this PETG behaves quite differently from more common PETG brands, so I’ve been experimenting with it on a Bambu Lab A1 and ended up with a custom filament profile that gives me very clean walls, consistent corners, and good dimensional accuracy at relatively high print speeds.
I’m attaching screenshots of my current filament and process settings instead of listing all values here, but a few notes that may be useful:
- The profile is based on Bambu’s 0.20 mm Standard preset and then adapted specifically for this PETG: default line widths (I’ve also tested narrower widths), slightly reduced infill widths, and adjusted retraction/extra‑restart to clean up the seam and remove gaps on interior corners.
- Flow calibration (A1 Flow Rate Calibration in Bambu Studio) consistently pushed me toward a fairly low flow ratio of around 0.76 for this spool. In my view this happens because this filament is engineered for high‑speed movement, not for high flow density (as in HF‑nozzle extrusion). It stays more viscous under load and doesn’t “flood” the nozzle as easily as softer PETG blends, so the slicer determines that a lower flow ratio gives cleaner deposition. With that value I get very flat large first layers and no signs of under‑extrusion in the walls, so I kept it even though it’s unusually low compared to typical PETG or PLA profiles.
- You’ll notice in the screenshots that **Max volumetric speed is limited to 20 mm³/s . That is intentional: even though the filament is marketed as “Hyper Speed”, it’s still PETG and noticeably more viscous than PLA. On the A1, I reached ~23 mm³/s in testing, but I optimized the profile for 20 mm³/s to ensure consistently clean results on real parts and avoid waviness or inconsistent infill on larger surfaces. Keeping the volumetric limit conservative lets me run high movement speeds (fast infill, reasonably fast walls) without starving the nozzle or compromising surface quality. In practice this trades a little theoretical peak speed for very stable extrusion on larger real‑world parts.
- Cooling is kept on the low side, as expected for PETG. The profile relies more on controlled flow, seam tuning, and retraction behavior than on strong part cooling, in order to avoid brittleness and maintain good layer adhesion.
This profile is aimed at reliable functional parts and clean outer surfaces, not just speed‑benchmark numbers.
I’d really appreciate feedback from other A1 owners using AzureFilm Hyper Speed PETG—what profiles you use, what settings worked for you, and how your print quality compares using this material.
