What's the maximum layer height I can achieve on a consumer 3D Printer?
I'm using a bambulab a1 mini more specifically but I'm interested in all answers to that question.
Personally, I think the look of the extrusion can be quite nice if it's not trying to be hidden โ especially with transparent PETG or something similar.
Your maximum nozzle diameter depends on your extruder. Most printers run one of a few fairly standard designs. It wouldn't surprise me if there are larger diameter nozzles made for your extruder, but they're not marketed for your printer.
