      It depends on the model being printed.

      1 micron is easy to achieve on the Z axis with almost any printer, using any 3d printing technology (FDM/SLP/SLA/etc).

      In the X/Y axis, the vast majority of FDM printers are off the table for 1 micron - increasingly so as the Z height of the model increases, especially on bed-slingers like the Ender 3. The taller the model, the harder it is to maintain accuracy on X and Y.

      In SLA/DLP printers, it’s all about the motor, controller, and whatever shields excess light/beam diameter.

      To answer your question directly: I have no trouble getting highly reliable micron accuracy in a $99 Creality Halot. The key is to understand your model in relation to the pixel density of the screen. Some calibration prints tell you where the steps are, describing the relationship between input and output - which will most certainly be different from printer to printer at the consumer level. Once you have that data, some simple math tells you exactly how to design your object in a way that takes these natural constraints into consideration.

      Yes - at any scale, even at the size of a car…or a battleship. When you accept the constraints of the hardware into the design of the object being produced, you can get micron repeatability out of just about anything.
