Choosing the correct filament for your 3D printer is important. Some printer manufacturers require you to use their specific 3D filament, or you warranty will be voided. Others are more open about the type of filament you use when printing in 3D, but you need to be careful to purchase a product that won't jam up your printer's extruder.
