Extrusion - 3D CAD Models & 2D Drawings
The FDM 3D Printing Process. When the FDM printer begins printing, the raw material is extruded as a thin filament through the heated nozzle. It is deposited at the bottom of the printer platform, where it solidifies. The next layer that is extruded fuses with the layer below, building the object from the bottom up layer by layer.
