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.
==== Layer Height ====
The Layer height is the first and most obvious parameter to tweak in order to obtain the preferred results. Larger layer heights will lead to coarser resolution in height (along the Z axis). Lower layer heights will lead to higher resolutions along Z.
==== Line Width ====
==== Print Speed ====
==== Nozzle Temperature ====

====Open Model====
Your ''stl'' file contains a set of triangular faces in 3D space. If you send this to a 3D printer, it will not know what to do. A slicer “slices” the 3D object into layers and then generates machine code (contained in a gCode file). Different printers work better with different slicers. The slicers need to be downloaded onto your computer. If you happen to not have access to a personal computer in our space, note that all our computers have all the software required to slice a print for any of our printers.
