 Filaments are mostly sold in 1.75 mm and 2.85 mm diameter variants, with 1.75 mm being the significantly more common variant. For larger 3D printers or those where the nozzle has been changed accordingly, the thicker 2.85 mm filament is used.
 
-Ordinary 3D printers can only print with one filament at a time, so if you want to print in a different color or with a different material, you have to change the filament spool. However, there are 3D printers that can print with two or more filaments at once. In this way, multicolored objects or objects made of different materials can be printed, e.g. by printing the support material (see more below, section [support material](#support-material-and-bridges)) from an easily removable material and the actual object from a stable material.
