This is powder bed fusion technology for metal printing and some technologies for printing composite materials and plastics. The necessary tools for reverse engineering, support calculations, in-service measurements, laboratory tests and material analysis are available. The contribution presents the potential of additive technologies in the maintenance of machines and equipment. Examples of printed spare parts are shown and commented on. © 2023 The Authors, Published by Elsevier B.V.
