Additive production can be characterized as multidisciplinary and generally consists of several production processes, namely the preparation of production and the assessment of technology and design of prototypes. This is followed by production phases (simply the production of plastic or metal prototypes) and postprocessing (heat treatment, surface treatment, finishing methods and inspection and measurement). Within the subject of programming and operation of 3D printers, students will focus on the "production phase" and practically get acquainted with the operation of 3D printers across all available technologies. They will gain much-needed experience for possible practice.
