With this work, I deal with the topic " Prototype modeling of the city of Pula " as well as detailed modeling of individual landmarks of the city of Pula. The preparation of the model for 3D printing, and the comparison of materials and prices are also included in the creation of the final work. Descriptions and types of additive technologies are listed, and the main type is FDM - Fused Deposition Modelling. FDM technology is the most widespread technology for commercial 3D printers. Additive technologies enable numerous material and energy savings compared to conventional technologies such as various particle separation procedures. The development of additive technologies began in 1945 when science fiction writer Murray Leinster envisioned a machine that would replicate existing drawings with a “moving arm” using molten polymer to shape a 3D object. In 2018, the first 3D house was printed, and in the coming years the technology will certainly progress. The printing time of 3D models is measured in hours, and some models require up to several days for the printing to be finally finished. 3D model Arena, which has a mass of 66 grams, printing time is 4 hours and 3 minutes. To create the entire model of the city plan that was modeled for the needs of this final work, 1800 grams of filament and a little more than 14 days of non-stop work of the 3D printer are needed. One of the many CAD (Computer-aided design) programs was used for modeling purposes, and specifically, it is the Fusion 360 program.
