Paste Extruder

A 500mL ductile-paste extruder at 7 bar, driven by a custom-built control circuit for stability.

A ductile-paste extruder built for a 3D printer, with a 500mL tank under 7 bar of pressure. Off-the-shelf control electronics were not precise enough for this flow, so the drive circuit was custom designed to keep the extrusion stable.

The assembled extruder standing on the bench, its tank held above a threaded rod and motor.

The board layout in magenta and cyan traces on black, laid out for the motor driver.

The finished board wired inside its printed case, the button panel folded open beside it.

The extruder hung from the printer's arms, its tank angled over a bench of tools.

Two coiled clay pots on plaster discs flank the machine, the feed hose looping between.
