Abstract
The present disclosure generally relates to an additive manufacturing system. The system can comprise a material supply module for melting and pressurizing a printing material; a micro-screw printing head comprising: a micro-screw comprising a threaded stem portion and a conical head portion, wherein the threaded stem portion is threaded throughout its length for volume measurement; a sleeve, and a nozzle, wherein a distal end of the nozzle comprises: a conical inner surface, and an outlet port for dispensing the print material, wherein the conical inner surface of the nozzle is configured to be in contact with the conical head portion of the micro-screw to stop dispensing the printing material at the nozzle when the micro-screw printing head is in a closed position; a driving module comprising: a rotation motor for driving a rotating motion of the micro-screw, and an actuator for driving a vertical motion of the micro-screw.
