• 20 microns layer height resolution, consistently achievable - is the highest - with Ultimaker and 0.4mm nozzle. Note that resolution is only 60 micron with 0.25 mm nozzle, which is a reflection of the Bowden design (long extruder to head distance)
• Rest including Prusa and Lulzbot are at 50 microns.
