Presented is a method for forming at least one structure on a substrate. Utilizing a low-temperature plasma jet, powder, of which the structure shall be constructed, is applied to a surface of the substrate. Using at least one laser beam, heat is input into the substrate and/or the powder within a laser incidence region on the substrate. The heat input delays solidification of the powder particles, which are partly or fully melted in the plasma jet, on the substrate and thereby enables the formation of good adhesion between the applied powder, and thus the structure constructed out of the powder, and the substrate. The invention further relates to an apparatus for performing the method.
