Abstract
Preliminary observations suggest that 3D-printed robotic parts exhibit varying performance based on printing conditions, prompting a methodological investigation into commercial materials for additive manufacturing. The objective of this study is to explore the effects of main factors in Fused Deposition Modeling (FDM) and to test the hypothesis that 3D-printed parts can be accurately represented using numerical models developed from simple geometries. Tensile tests were conducted on PLA and PETG specimens, produced using different printer setups and part orientations, following the ISO 527 standard. The study examines how these variables influence material properties such as tensile strength and interfacial bonding strength (IFBS). The findings highlight significant variations in mechanical properties across different setups, providing practical design criteria for achieving specific reliability levels in additively manufactured components. This research is unique in presenting reliable, measurable data on the performance of commercially available 3D printers, enhancing the understanding and optimization of FDM-printed parts. The results contribute to the development of a numerical model that can reliably predict the behavior of precise robotic components, thus streamlining the design process and improving part performance.
Abstract (croatian)
Preliminarna opažanja sugeriraju da 3D-printani robotski dijelovi pokazuju različite performanse ovisno o uvjetima printa, što je potaknulo metodološko istraživanje komercijalnih materijala za aditivnu proizvodnju. Cilj ove studije je istražiti učinke ključnih faktora u Fused Deposition Modelingu (FDM) i testirati hipotezu da se 3D-printani dijelovi mogu točno prikazati pomoću numeričkih modela razvijenih na osnovnim geometrijama. Vlačna ispitivanja provedena su na PLA i PETG uzorcima, proizvedenim korištenjem različitih postavki printera i orijentacija dijelova, u skladu sa standardom ISO 527. Studija ispituje kako ovi faktori utječu na svojstva materijala poput vlačne čvrstoće i međuslojne čvrstoće (IFBS). Rezultati ukazuju na značajne varijacije u mehaničkim svojstvima među različitim postavkama, pružajući praktične kriterije dizajna za postizanje specifičnih razina pouzdanosti u aditivno proizvedenim komponentama. Ovo istraživanje jedinstveno je po pružanju pouzdanih, mjerljivih podataka o performansama komercijalno dostupnih 3D pisača, čime se poboljšava razumijevanje i optimizacija FDM-printanih dijelova. Rezultati doprinose razvoju numeričkog modela koji može pouzdano predvidjeti ponašanje preciznih robotskih komponenti, čime se pojednostavljuje proces dizajna i poboljšavaju performanse dijelova.
