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.

Abstract

The present invention relates to an auxiliary drive arrangement for a pedal-powered vehicle having a drivetrain comprising a pedal- driven sprocket and chain (15B) for connecting pedals (34) to a driven wheel. The auxiliary drive arrangement comprises: an electric motor (6) arranged to be mounted to the vehicle; a power source (14) for the electric motor; and a sprocket member (24) comprising first and second sprockets (24A, 24B). The sprocket member is configured to be selectively attachable via an attachment formation to the drive train of the vehicle. The sprocket member is configured to be mounted on an existing pedal sprocket and operatively connected to the electric motor to provide a drive path from the electric motor to the pedal-driven sprocket via the sprocket member.
