ABS filament is one of the standard materials used in desktop 3D printing (the other being PLA). It is a strong plastic with some flexibility, ideal for professionals or those putting tricky prints together. When choosing ABS, be sure that the printer has a heated build platform. Without one, the filament won’t adhere properly to the bed and there will be deformation to the 3D print. All Mitus ABS filament is Made in America.
