Abstract

A direct radiation deposition apparatus comprising a feed conduit and a nozzle arranged to deliver powder to a substrate, and a radiation source arranged to simultaneously direct a radiation beam onto the substrate and thereby melt the powder, wherein the apparatus further comprises an actuator arranged to apply a vibration to the nozzle which causes powder to fall from the nozzle onto the substrate.
