Aqueous Based ExtrusionFabrication of Ceramics on Demand
reservoir plunger. This would in theory reduce the applied pressure， thereby stopping
material extrusion.
In this paper material deposition tests are conducted， where the ram extruder
retreating velocity is varied in order to develop a technique that can be used for
starting/stopping the extrusion process on demand. A new extrusion mechanism is
designed to improve process capabilities. Parts are then fabricated with the use of
starting/stopping the extrusion on demand with emphasis being placed on deposition of
sharp corners and edges.
