A2L precision and tolerance accuracy

Bambu Lab A Series General Discussions

I am very curious. whats the precision of the A2L.
if you printed a cylinder of 100mm diameter. what is the smallest hole need to allow the cylinder to passthrough would it be 100.1mm or 100.05mm.
if the cylinder is 10mm would the diameter be 10.1mm or 10.05mm

currently for my A1 mini I can achieve an offset of 0.05mm with Bambu Lab PETG HF and PETG Basic. That means if the diameter of the cylinder is 100mm the hole need to be 100.1mm.

Would the A2L be as good as my A1 mini or Better.

to those who have the A2L hope you could help answer this

thanks

Theoretically the printer has a stated precision but they are all good enough that this is basically meaningingless, and it depends on filament and environment. Filament extrustion parameters, filament shrinkage, printing temperature, the movement of air in the room etc.

Also I don’t think your numbers are right. If the hole is drawn at 100.1mm diameter, you still have to deal with the fact that the plastic being extruded is, what? 0.2mm wide (assuming 0.4mm nozzle), so the hole will come out too small.
