Direct print extruder with a multi-faceted adjustable output pressure

Abstract

At a high level, aspects herein are directed to an extruder having an adjustable pressure output. The extruder comprises a frame and a barrel having an internal cylindrical volume that has a first longitudinal axis extending between a first end and a second end. The barrel is coupled to the frame. The extruder also includes a screw within the barrel internal cylindrical volume. The screw has a distal end and a proximal end, and is rotationally movable within the internal cylindrical volume and linearly moveable within the internal cylindrical volume. The screw distal end is linearly moveable at least 1 mm relative to the barrel end having a nozzle. The extruder further includes a linear drive coupled with the frame. The linear drive is coupled with the screw and provides linear movement coaxial with the first longitudinal axis to linearly move the screw.
