=== 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.

There are many different kinds of filament you can use on the 3D printer, ranging from PLA, ABS, TPU, and Nylon. The most common of these are PLA and ABS.

PLA stands for Polylactic Acid, it is the most common desktop 3D printing filament because it is odorless and very hard to warp on its own, therefore not always a need for a heated bed.

==== Sizing of Filament ====

There are two mainstream sizes of filament, 3.00mm and 1.75mm. The 3.00mm filament is typically used on higher end machines--printing stronger and more detailed models. Hobbyist printers lean more towards the 1.75mm filament, for marketing purposes as well as hardware purposes. The Prusa i3's use 1.75mm filament.
