The article presents the results of research aimed at redesigning a jewelry product with the use of modern reverse engineering methods. A detailed review of the literature was conducted and the essence of the application of this technology in the era of Industry 4.0 was presented. The 3D digitization of the research object was performed with the use of Aicon SmartSCAN-HE R8 and DAVID-SLS3 scanners. The obtained better quality file was edited in Autodesk Meshmixer 3.5 software. On the basis of the created model, a 3D print was made using FDM (Fused Deposition Modeling) and DPP (Daylight Polymer Printing) technology with two different materials-HIPS (High Impact Polystyrene) and photopolymer casting resin. The final stage of the work was the measurement of the surface roughness of the B101 (CuSn10P) tin-phosphorus alloy castings made using the method of investment casting.
