Abstract

Aditivne tehnologije prisutne su već nekoliko desetljeća, međutim u zadnjih desetak godina
doživjele su značajan napredak što je rezultiralo širenjem područja primjene. Osim industrijskih
primjena i primjena u medicini, proširilo se i osobno korištenje navedene tehnologije preko
niskobudžetnih pisača koje ljudi koriste za osobne potrebe. U prvom dijelu rada dan je pregled
tehnologije i principi na kojima se temelji. Nadalje, opisani su najčešći postupci s naglaskom na
tehnologiju taložnog očvršćivanja (FDM) budući da su se njome ispisivali modeli u
eksperimentalnom dijelu rada. Za FDM tehnologiju opisani su najčešće korišteni materijali,
navedene su najčešće greške i dan je pregled prethodnih istraživanja koja donose zaključke o
parametrima koji utječu na dimenzijsku točnost i hrapavost površine.
U eksperimentalnom dijelu rada, model propelera ispisan je u tri različite orijentacije, a
postupkom 3D skeniranja obavljena je analiza površine i ispitivanje dimenzijske točnosti.

Abstract (english)

Additive technologies have been present for several decades; however, in the last decade, they
have experienced significant progress, resulting in the expansion of their application areas. In
addition to industrial and medical applications, personal use of this technology has also
expanded through low-budget printers that people use for personal needs. The first part of the
paper provides an overview of the technology and the principles on which it is based.
Furthermore, the most common procedures are described, with an emphasis on Fused Deposition
Modeling (FDM) technology, as it was used to print models in the experimental part of the study.
For FDM technology, the most commonly used materials are described, common errors are
listed, and a review of previous research is provided, drawing conclusions about the parameters
that affect dimensional accuracy and surface roughness.
In the experimental part of the study, a propeller model was printed in three different
orientations, and a 3D scanning process was used to analyze the surface and investigate
dimensional accuracy.
