=== Infill ===
=== Infill ===
+Infill has to do with a 3D print's structural integrity. It can be multiple shapes and patterns (providing different strength optimizations), different sizes, and different thicknesses. Infill ranges anywhere from 0% (hollow) to 100% (solid). It is very unlikely you'll ever want a print to be 100% infill because it takes an insane amount of filament and takes a lot of time to complete.
+
+Most 3D prints are 20% infill since it is the most optimal choice for cost efficiency and durability.
+
+If your concern is cost, a lesser infill density is a good way to go. If strength and mass is important, a higher density (between 30%-50%) is a good estimate. When using a higher infill, always double check to make sure it's a good idea for your part, and that you're using the right machine. Other 3D printers in the prototype lab have the option of a stronger filament than PLA or ABS, so it may be a better idea to print for strength on those rather than the Prusas.

−== Usage ==
+==== Picking a Model ====
+- slicing it / generating gcode (brim, size, rotation, infill, support)
+- setting up the printer (temperature [preheating], choosing a file)
+- watching the print (brim, speed, support, 30%)
+- what to do if it fails (brim comes off, nozzle drags print around, etc)
+- finishing a print
−- loading new filament
−- pausing or stopping a print
