For Fused Deposition Modeling, or FDM, printers like the ones in build IT, one variable that affects the final quality of a 3D print is the layer height. Typical layer heights are between 0.1 millimeters and 0.5 millimeters. The surface quality of the finished part is proportional to how small the layer height is; smaller layer heights result in smother surface finishes.

For FDM printers, the number of layers is one indicator of how much time a 3D print will take. Choosing a smaller layer height will divide a 3D model into more layers, increasing the print time. For example, an object printed at 0.4mm layer height would take half as much time as an object printed at 0.2mm layer height, because there are half as many layers. Due to machine limitations, the minimum layer height for all prints done in build IT is 0.2mm.
