There are many different kinds of 3D printing filaments. First of all, they come in two CONVENTIONAL diameters: 1.75mm and 3.00mm.

The most common materials used in FDM 3D printing are PLA and ABS. They are popular for their ease of use (ABS being a little more complicated to 3D print), and their affordability.

But as far as what materials you can print with are concerned, there are almost no limits. It is possible to print in PURE metal, food and all SORTS of thermoplastics whereby metal and food don’t come in filament form for obvious reasons. But don’t be confused, if you see a spool of filament that says metal on it. In this case, metal dust is MIXED with thermoplastic material for use in desktop FDM 3D printers.
