Fused deposition modelling (FDM) printers extrude melted material through a nozzle. As this happens, the nozzle is moved along a predetermined toolpath (a set of spatial coordinates), laying the extruded material on existing surfaces along the way. The toolpath is generated from CAD models in a software called a slicer software, named this way given that it slices 3D models in thin 2D layers which when stacked reform the original model.

=== Important Parameters ===

It is important to keep a few parameters in mind when FDM printing. Using the proper parameters will ensure that your print comes out right!
