Main objective of this work was to rebuild and upgrade a decommissioned additive manufacturing device. At the beginning of the thesis, an analysis of the current state of the equipment was made, dividing the original components into usable and non-usable ones. The calculations were used to define suitable replacements for the missing components, which formed the basis for the requirements list. Subsequently, fixtures were designed using a CAD software to attach new parts with the respect to the modularity of the equipment regarding the possibility of future upgrades. To enhance the print quality of the device, the most recent additive manufacturing techniques and trends were applied, which resulted in creation of multiple variants. Upon completion, finished variants were compared with the initial state of the device in terms of surface accuracy, surface quality of 3D printed model and printing speed.
