Extrusion techniques will extrude material from a precisely controlled print head to form each layer of the model. After a layer is completed, the print head will rise or the build tray will descend one layer thickness so that the print head can extrude the next layer. This creates visible stepping. Considering there is no supporting powder or surrounding media, extrusion prints will always require support structures for stalactites and overhangs with a large minimum overhang. Despite the support structures, extrusion processes are typically fast and affordable.
