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 thus given that it slices 3D models in thin 2D layers which when stacked reform the original model.

=== Extruder and Nozzle (CAUTION: HOT!) ===
===Extruder and Nozzle (CAUTION: HOT!)===
The extruder heats and pulls partially melted filament into the nozzle. During a print, the extruder and nozzle will heat up to over 210°C, so exercise caution around it. The location of the printer nozzle and extruder is controlled on an axis system (typically) made up of belts and gears. This assembly can be moved while the printer is idle by gently pulling on the extruder/nozzle assembly, being careful as parts of this assembly can be extremely hot even after a print has finished. If the printer is printing, or has recently been printing, the motors will still be engaged. Set the printer to idle and wait a few minutes, or power off the machine to disengage the motor lock.

=== Build Plate (CAUTION: HOT!) ===
===Build Plate (CAUTION: HOT!)===
The build surface is where the printed part is placed on. On most of the Makerspace printers the build plate is heated to 60°C (and can go as high as 110°C) during printing, so exercise caution around it. The plate can be raised or lowered while the printer is idle by going to Maintenance→Advanced→Raise/Lower Build Plate. If the printer is not printing properly, this may need to be adjusted, by using the three knobs (thumb screws) on the underside of the plate. This can be leveled through the printer’s onboard software by going to Maintenance→Build Plate, and following the onscreen instructions.

=== Filament Spool ===
===Filament Spool===
The filament spool can be found attached to the back of the printer. If the printer is out of filament, it can be replaced by going to Material→Change in the printer’s user interface and following the onscreen instructions. It can also be replaced midway through printing by selecting Pause→Change Material and following the onscreen instructions.

At the uOttawa Makerspace we have several different types (brands) of printers. When printing you will encounter either the Ultimaker, MakerBot, or Dremel. In general, the processes are similar.
