FDM (or fused deposition modeling) 3D printers use filaments to create the objects they print. These filaments are available in a variety of materials and they come on spools. The material from the spool is fed through the printer’s extruder and out of the heated nozzle to create the 3D product, layer by layer.
The type of filament you need depends on the type of object you want to print. We break down each of the different 3D printer filaments available, listing their properties and pros and cons, to help you decide which one is best for your particular project.
