摘要： A 3D printer apparatus for printing a refractory materials on the surfaces of workpieces in accordance with a given program is disclosed. The apparatus contains a first generator for generating a first atmospheric ICP beam, a second generator for generating a second atmospheric ICP beam, and a bouncing tube between the generators for breaking clusters of precursor nanoparticles into elementary charged nanoparticles that penetrate in a premelted state into a plasma discharge formed in the second generator under the inductive coupling with a saddle antenna, which encompasses the second generator. The outlet nozzle of the second generator emits the second beam onto an extractor plate that is a part of a plasma gun, which converts the second beam into a finely controlled focusing beam capable of printing a material even on the inner surfaces of deep small diameter gas holes of showerheads.
