3d printer head

Abstract

The present invention relates to an additive layer manufacturing device comprising a printer head configured to provide deposition of an extrudate in use. A printer head for a fused deposition modelling printer is disclosed. The printer head comprises a body having a chamber for holding material to be deposited by the printer head through an output aperture. A heating element heats material contained within the chamber. A cover member is moveable relative to the output aperture so as to vary the amount of the output aperture that is uncovered such that material can be extruded therethrough. A first feed system is configured to feed a first material to the printer head. A second feed system is configured to feed a second material to the printer head. The device may comprise a mixing system configured to mix the first and second material in the printer head, such that the extrudate comprises a mixture of the first and second material.
