Abstract

A controller operates a first actuator to produce relative movement between a multi-nozzle extrusion printhead and a support member along a predetermined path for one layer of a three-dimensional printed object. The multi-nozzle extrusion printhead includes a housing with a chamber, a valve assembly having a plurality of passageways, and a planar member having a plurality of nozzles. The passageways of the valve assembly and the nozzles of the planar member are connected to one another in a one-to-one correspondence and valve members of the valve assembly are operated to open and close melted extruded material flow to the nozzles selectively and independently.
