Abstract
Ovim radom istražuje se direktan utjecaj orijentacije i vrste ispune na mehanička svojstva 3D ispisanog proizvoda. Odabir odgovarajuće orijentacije može biti ključan u ostvarivanju željene kvalitete proizvoda, a ima i značajan utjecaj na samo vrijeme izrade. Budući da je cilj svake proizvodnje, pa tako i aditivne minimizirati vrijeme potrebno za izradu, uz maksimiziranje kvalitete proizvoda, potrebno je poznavati namjenu budućeg proizvoda te postaviti optimalne parametre sukladno svrsi proizvoda. Osim orijentacije, oblik ispune također ima direktan utjecaj na mehanička svojstva, kao i temperatura mlaznice i radne podloge, brzina ispisa, visina sloja te količina bridova. Neadekvatno postavljanje parametra izrade rezultirat će vidljivim greškama na modelu, a neke od njih će također biti navedene u radu. Tehnologija 3D ispisa koja će se koristiti za izradu ispitnih tijela je najzastupljenija tehnologija ekstruzije materijala, poznatija pod skraćenicom FDM ispisa, a eksperimentalno testiranje se provodilo u sklopu Laboratorija za preradu polimera po uzoru na norme ISO 527-2 i ISO 179-1. Osim FDM tehnologije, pobliže će biti objašnjene i druge aditivne tehnologije.
Abstract (english)
This study investigates the direct impact of orientation and infill type on the mechanical properties of 3D-printed products. Choosing the appropriate orientation can be crucial for achieving the desired product quality and significantly affects production time. Since the goal of any manufacturing process, including additive manufacturing, is to minimize production time while maximizing product quality, it is essential to understand the intended purpose of the final product and set optimal parameters accordingly. In addition to orientation, the infill pattern also has a direct influence on mechanical properties, along with nozzle and bed temperatures, printing speed, layer height, and the number of outer perimeters. Inadequate parameter settings during production will result in visible defects on the model, some of which will also be described in this paper. The 3D printing technology that will be used for the production of test specimens is the most widely used material extrusion technology, better known by the abbreviation FDM printing, and experimental testing was conducted within the Polymer Processing Laboratory following the standards ISO 527-2 and ISO 179-1. In addition to FDM technology, other additive technologies will also be explained in more detail.
