An extrusion 3D printer, which is used to print small plastics parts, is running out of input (consumable) materials. Which of the following is the correct name of the required input material for this printer?

Extrusion 3D printers heat filament from a roll and force it through an extremely narrow nozzle while moving the nozzle to the proper spot to form an object layer by layer. Filament comes in a variety of thicknesses and properties, so it's critical to double-check the printer's specifications before getting any new filament.
