Additive manufacturing apparatus

This invention describes a 3D printer component that precisely pushes out melted plastic. It combines a screw-based extruder with a gear pump, where the screw feeds directly into the pump, which has a specially shaped exit nozzle. The claims detail the connection between the screw and the pump's gears for smooth material flow, though the first claim provided is incomplete.

Why it matters: Since 2018, the demand for high-precision 3D printing and advanced materials has grown significantly. This system's focus on controlled material flow via a gear pump could address these evolving needs, with better simulation and manufacturing tools now available.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom gear pump, precise screw-pump interface, thermal control.
