Verification means the maker's own page was opened and the quoted words appear on it. It is not a physical test. How we verify.
The maker lists PLA as ideal for the A1.
Supported Filament PLA, PETG, TPU, PVA Ideal ABS, ASA, PC, PA, PET, Carbon/Glass Fiber Reinforced Polymer Not Recommended
The maker lists PETG as ideal for the A1.
Supported Filament PLA, PETG, TPU, PVA Ideal ABS, ASA, PC, PA, PET, Carbon/Glass Fiber Reinforced Polymer Not Recommended
Note : For PETG and PETG-CF/GF, an enclosed printer is recommended to prevent low ambient temperatures from reducing the model's interlayer strength.
The maker lists TPU as ideal for the A1.
Supported Filament PLA, PETG, TPU, PVA Ideal ABS, ASA, PC, PA, PET, Carbon/Glass Fiber Reinforced Polymer Not Recommended
The maker lists PVA as ideal for the A1.

When printing filaments containing hard particles (CF, GF, etc.) ... it is necessary to replace the nozzle with hardened steel to prevent excessive wear
On the A series (A2L, A1, A1 mini) the nozzle detaches from the heating assembly, so the nozzle can be replaced on its own.
The A series nozzle is easily detached from the heating assembly ... Compatibility: A2L/ A1 / A1 mini
The A1 ships with a 0.4 mm stainless steel nozzle.
Hot End All-Metal Nozzle Stainless Steel Max Hot End Temperature 300 °C Nozzle Diameter 0.4 mm (Included)
Bambu says filament with hard particles such as carbon or glass fibre needs a hardened steel nozzle in place of the stock stainless one.
When printing filaments containing hard particles (CF, GF, etc.) ... it is necessary to replace the nozzle with hardened steel to prevent excessive wear
A series printer comes standard with a 0.4mm stainless steel nozzle, and a hardened steel nozzle can be upgraded to an optional upgrade.
PTFE tube carries the filament from the AMS or the external spool holder to the extruder, which is inside the toolhead. Bambu recommends replacing the tube every two months under normal use, and inspecting it every month with highly abrasive filaments such as carbon fibre or glow-in-the-dark.
routing it from the Automatic Material System (i.e. AMS) or the external spool holder to the extruder inside the printer toolhead
Under normal usage, we recommend replacing the tube every two months
When printing with highly abrasive filaments (such as carbon fiber or glow-in-the-dark filaments), we recommend inspecting the tube every month
The A1 comes with a textured PEI plate.
The A1 comes with a textured PEI plate (included in the unboxing package)
The A1 has 3 adjustable belt tensioners. It checks belt tension when it prepares to print and prompts you to re-tension a belt when needed; you do the tensioning.
The A1 is equipped with 3 adjustable belt tensioners.
If re-tensioning is confirmed to be necessary, the printer will display a relevant prompt. Please follow the prompt to tension the corresponding belt
The model name is printed on the front of the printer and shown on its screen.
