A 3D printer spreads layers of molten material according to the instructions it receives from a digital file to form the final object.
In 3D printing, the resolution is equal to the thickness / height of each layer. This resolution is measured in microns and each micron is 0.001mm, so the smaller the size of each layer, the higher the resolution and the better the details of the object. This however, affects the print time, and consequently the cost, of a process. Today, printers available in the market can print in various levels of resolution, from 50 to 800+ microns.
