The introduction to the thesis explains the concept of additive manufacturing and the general principle of operation of the procedures used. Listed are materials used in additive manufacturing, such as: acrylonitrile butadiene styrene (ABS), polyamides (PA), polycarbonate (PC), poly (methyl methacrylate) (PMMA), poly (vinyl chloride) (PVC) , polyurethane (PUR), epoxy resins, composite materials, ceramics, steel, aluminium, titanium and other light alloys. The division of additive production processes is briefly described, namely: photopolymerization (stereolithography), binder spraying (three-dimensional printing), material spraying (PolyJet), material extrusion (sedimentation), lamination (production of laminated objects), powder melting (laser fusion) and direct deposition of materials. CAD and CAM systems are described as the basis of additive manufacturing. The principle of operation of the FDM procedure is described in more detail, as a technology used to make a given pneumatic pump. The general characteristics of the machine used in this process are also shown in the table. The interface of the CAM system, which was used in the preparation of this thesis, is described in detail. The interface of the Mastercam CAM system is especially emphasized and lathe operations within the program are described in detail. The notion of reverse engineering as a relatively new technology to determine design features from products with little or no additional information on the processes involved in their original production was clarified and a 3D scan of the pump stem controller was performed (workshop design of the middle part of the housing was not available). In the section designing the manufacturing process, the processing of five parts of a given pneumatic pump within the selected CAM system is done in detail. Using the CAD system, sketches were obtained for structuring the technological process, and with the help of the CAM system, processing images were obtained for the elaboration of the technological process. All tools and processing modes that are most optimal for each individual procedure are also listed. Finally, all times of operations are calculated and are tabulated in the inset of this thesis.
