Roughness of the prototipes made by the 3D printing process

U ovom završnom radu opisan je razvoj aditivnih tehnologija od samih početaka pa sve do današnjih modernih visokokvalitetnih postupaka. Uz opis najznačajnijih postupaka aditivne tehnologije, posebno sam se osvrnuo na postupak 3D tiskanja jer sam mjerio hrapavost epruveta izrađenih tim postupkom, ali različitih debljina slojeva izrade. Pomoću tih mjerenja epruveta s različitim debljinama slojeva izrade ustanovio sam da će hrapavost biti veća što je sloj izrade veći i obrnuto.This final paper describes the development of additive technology from beginning until the present modern high-quality processes. With a description of the principal methods of additive technology, I especially mentioned the process of 3D printing because I measured the roughness of the test tubes made by this process, but with a different thickness of layers in their making. Using these measurement of the test tubes with a different thickness of layers, I established that the roughnesse is higher as the layer thickness is higher and vice versa
