The study is done to optimize labor costs for reverse engineering of products for new or existing series of railway rolling stock under repair: prototypes, scarce polymer or metal spare parts, non-standard devices, model and technological equipment, in the conditions of service and locomotive repair enterprises. The study objective is to develop training material describing step-by-step 3D scanning of spare parts by RangeVision optical 3D scanners with and without a rotary table, processing the resulting "scan" into an intermediate format file in peripheral programs before developing a solid-state 3D model. Research methods: Digital databases of .stl-files of rolling stock spare parts and 3D scanning materials developed by the authors during 2019-2025 were used to develop the methodology while implementing reverse engineering in service and locomotive repair production. The novelty of the work: The technique of reverse engineering of rolling stock spare parts produced by 3D printing in a limited time includes an integrated approach "from the original product to the printed spare part".
