A method of 3D printing an item, wherein a spray material comprising a powder entrained in an oxygen comprising carrier gas is emitted from a spray nozzle. The nozzlecomprises a constricted throatthat has a thermal conductivity of at least 10 W/mk and a hardness of at least 10 Rockwell C (HRC). The temperature of the throat does not exceed 250° C., and preferably does not exceed 200° C.

Method of 3D printing

A method for forming a 3D object, comprising running control means with reference to data which defines 3D shape parameters of an object such that the control means: •uses the data to control an applicator to spray material at a substrate to build the object out of progressively applied layers, wherein at least some of the layers have an initial inwardly tapered outer edge; and •for at least some such layers causing the control means to use the data to move the applicator to apply spray material to fill in the taper.
