The same two heads can also be used for multi-material printing, combining a semi-flex with a stiff material for example. Superior Positional Accuracy The S2 uses top quality linear motion components and a precision acme screw to achieve superior positional accuracy and repeatability. Superdrive feeder system Designed to especially with softer or more specialty materials in mind, the superdrive’s custom design features additional gripping and guiding of the filament all the way to the hotend to maximize reliability for specialty filaments.
