Abstract
A micro cold spray printer system having: a printer housing having a longitudinal axis; a transfer tube defining an optical chamber oriented parallel and coaxial to a the longitudinal axis of the housing the optical chamber having an exit; a particle supply inlet fluidly connected to the optical chamber, the particle supply inlet in operation supplying particles to flow through the optical chamber along the longitudinal axis and out the exit; and a laser that in operation emits a laser beam into the optical chamber to heat the particles to a selected temperature. The laser beam is directed at an angle that is not parallel to the longitudinal axis.
