你说的sub 100 micron是要求x,y axis?
From FAQ:
How accurate is the machine? The Ultimaker has the highest detail in the Z-direction of all 3D printers that use the same printing process, even those of up to 100,000 euros. It can lay down the material with a precision better than 0.1mm. However, the minimum size of a feature is limited by the nozzle size and settings that you choose. With practical settings, the features are almost always bigger than 0.5 mm, so thinner walls are not really possible. The resolution in the vertical direction is lower, because it uses a static layer height. The Ultimaker can print layers of 20 micrometers (which is less than 0.0008 inches). You can keep this in mind when deciding in which orientation you want to print your part.
