I’m not sure, but I’d bet that this is a debate over precision Vs accuracy.3D printers can be pretty precise in relative terms, but they are difficult to make accurate. Extruder style printers struggle with small feature size because the heating and cooling distorts from the reference size. .01mm resolution does not mean you accurately achieve .01mm parts. It means your machine can be commanded to make .01mm moves and will make them repeatably. That said, 3D printers aren’t bad. Small parts are just difficult.
