Abstract:
An extruder or other similar tool head of a three-dimensional printer is slidably mounted along a feedpath of build material so that the extruder can move into and out of contact with a build surface according to whether build material is being extruded. The extruder may be spring-biased against the forward feedpath so that the extruder remains above the build surface in the absence of applied forces, and then moves downward into a position for extrusion when build material is fed into the extruder. In another aspect, modular tool heads are disclosed that can be automatically coupled to and removed from the three-dimensional printer by a suitable robotics system. A tool crib may be provided to store multiple tool heads while not in use.

Claim (Index 1):
A three-dimensional printer comprising:\n a drive assembly including a power train configured to drive a filament of a build material along an axis of a feedpath for the filament; an extruder configured to removably and replaceably couple to the three-dimensional printer in a predetermined alignment to the axis of the feedpath through one or more registration features that align the extruder to the axis of the feedpath when the extruder is placed for use in the three-dimensional printer; and an extrusion head moveably coupled to the extruder to permit movement of the extrusion head within a predetermined range of linear displacement along the axis of the feedpath, the extrusion head including an input and a nozzle disposed along the axis of the feedpath when the extruder is placed for use in the three-dimensional printer, the input coupled to the nozzle by a chamber within the extrusion head for passage of the filament.
