The invention relates to a method for producing a part by means of a laser beam, with a nozzle (1) that sprays a metal powder towards a substrate (5). Initially, the trajectory of the nozzle is defined in a pre-determined manner, and then, during the production of the part (7): a theoretical reference distance D0 that has been previously recorded and a real distance which is then measured are compared, and
the trajectory of the nozzle is modified on the basis of a deviation threshold between said distances.
