| Use Case | Layer Height | Infill | Supports | Notes |
|---|
| Quick test / prototype | 0.30 mm | 10% | As needed | “Draft” - fastest; use standard mode |
| Standard project | 0.20 mm | 15-20% | As needed | Best all-around; Bambu default-optimized |
| Functional part | 0.20 mm | 30-40% | As needed | Use for load-bearing parts |
| Fine detail / display | 0.15 mm | 15% | As needed | Bambu achieves excellent detail at speed |
| Solid reference part | 0.20 mm | 40-50% | Rarely | Rarely needed; modern infill sufficient |
| Filament | Nozzle Temp | Bed Temp | Notes |
|---|
| PLA (standard) | 200-210C | 50-60C | Fastest print times; Bambu-optimized profiles |
| PETG | 230-250C | 70-80C | Slight cooling fan reduction for layer adhesion |
| TPU | 220-240C | 20-30C | Best quality with Bambu’s tuned retraction |
| ABS | 240-260C | 100-110C | Requires chamber heating; enclosed AMS recommended |
Check Bambu’s material database for exact profile updates - these are dynamically optimized.
| Overhang Angle | Supports Needed? | Recommended Setting |
|---|
| < 45 | No | None |
| 45-60 | Maybe | Auto-supports may activate; accept defaults |
| > 60 | Yes | Bambu auto-tree supports; minimal removal |
| Bridge < 20 mm | No | Bridges excellent on Bambu; no supports needed |
| Bridge > 20 mm | Maybe | Often bridgeable; preview before confirming |
| Problem | Likely Cause | Fix |
|---|
| Nozzle clogging mid-print | Thermal runaway / wet filament | Dry filament in AMS; check nozzle temp |
| Layer splitting or separation | Wrong material in AMS slot | Verify correct material in Bambu Studio |
| Stringing / blobbing | Cooling fan reduced too much | Increase cooling; adjust material profile |
| Print lifts off bed | Rare on Bambu; bed leveling drift | Auto-calibrate via Bambu Studio |
| Holes undersized | FDM tolerance - always undersized | Add 0.3-0.4mm to hole diameter |
| Part broke at layer boundary | Weak axis perpendicular to layers | Reorient so load is parallel to layers |
| Print aborts unexpectedly | AMS issue / filament jam | Clear AMS; verify filament path is smooth |
| Multi-material print misaligned | Nozzle offset miscalibration | Run auto-calibration in maintenance menu |
