When asking for help, please provide as much information as possible about your inquiry.
Including pictures and detailed information about the printer model, print speeds, filament type and settings used will help get the appropriate solutions.
It is also recommended to include a .3mf file of the model you are trying to print. This ensures the suggestions received will be more accurate.
Hello, I am an interior designer currently working on a lampshade project using a Bambu Lab P2S.
I have attempted to print the same model twice, but encountered different types of print failures both times. I am seeking advice on the potential causes of these errors.
I have attached the 3MF file and photos of the results for your review.
[1. Setup & Materials]
- Printer: Bambu Lab P2S (with AMS 2 pro)
- Filament: PETG Translucent
- Machine Condition: Purchased in January this year; no specific maintenance (cleaning, re-greasing, etc.) has been performed since.
- Settings: Please refer to the attached 3MF file for detailed slicer settings.
[2. Symptoms] (Two attempts of the same model)
Although the models are identical (except for being mirrored), they exhibited different failure patterns:
- Model A: The print failed completely from the mid-section as the layers stopped adhering/extruding properly.
- Model B: There was a significant layer shift at the bottom, but the printer managed to recover and finish the rest of the model.
[3. My Hypotheses]
Hypothesis 1: Height Issues (250mm)
- The model height is 250mm, which is very close to the maximum build volume (256mm). I suspected stability issues, but Model B finished despite the height, and the errors occurred at the bottom/middle sections.
Hypothesis 2: Lack of Supports
- I enabled the “Auto-generate Support” option in Bambu Studio, but no supports were actually generated in the sliced result. I am wondering if the lack of supports in specific areas might be causing these failures.
Hypothesis 3: Lack of Maintenance
- Since I haven’t performed any maintenance since January, I suspect that debris or lack of lubrication on the Z-axis lead screws might be causing irregular movement at certain heights.
I would greatly appreciate any insights on my slicing settings or potential hardware issues. This is a crucial piece for my design project, and I am eager to get it printed successfully.
Thank you in advance for your help!
