Hi, my name is Pedro and I’m based in São Paulo, Brazil.

I recently bought a Bambu Lab A1 to prototype custom furniture models that will later be produced in wood. I’m scaling down my armchair designs to 10% of their original size and arranging four units per plate, using tree supports in Bambu Studio.



Since the beginning, I’ve faced a persistent issue:

The tree supports fail consistently.

The trunks come out torn, detach from the bed, or partially collapse during printing, causing the models to fail. This happens across every test I’ve run.



Here’s what I’ve already tried:

	•	Custom preset created with help from AI (unsuccessful)

	•	Clean system preset (0.08mm Extra Fine @BBL A1)

	•	Manual filament setup with manufacturer’s data (PLA Areia Bege Max High Speed – National3D, Brazilian brand)

	•	Generic PLA profile from Bambu Studio

	•	Full calibration before every print

	•	Stable base (solid hardwood nightstand)

	•	External brim

	•	3-layer raft (for the feet of the models)

	•	Slight speed reductions for printing and support interface

	•	Switching tree support style (standard ↔ organic)

	•	Fine-tuning trunk and support settings (with AI assistance)

	•	Contacted the seller (Beehive 3D in São Paulo)

	•	Consulted OpenAI’s assistant throughout the process



None of these changes fixed the problem. Some tree supports still print weak, malformed, or fail entirely.



I’m hesitant to just drastically reduce print speed as a workaround.

I chose BambuLab based on its reputation for plug-and-play performance, expecting a shorter learning curve and a reliable system that didn’t require deep engineering knowledge to troubleshoot.

So far, my experience has been the opposite.



I really want this machine to perform to its actual advertised capability. I’m not ready to accept that I’ve bought a printer that only works reliably with “crutches” like massive speed reductions even on fine detail presets.



I’m looking for technical advice or any practical tips from people with more experience. I need a viable solution, because the whole point of buying the A1 was to produce functional, visually clean miniature furniture prototypes.



Any help would be deeply appreciated. Thanks in advance.
