Abstract

Diplomska naloga preučuje vpliv hladilno-mazalnega sredstva na mehanske lastnosti 3D natisnjenih prototipov iz materialov PLA in PLA, okrepljenega z ogljikovimi vlakni (PLA+CF). V raziskavi so bili analizirani vzorci z različnimi gostotami izpolnitve (20 %, 40 %, 60 %, 80 % in 100 %), pri čemer so bili primerjani vzorci brez izpostavitve in vzorci, izpostavljeni hladilno-mazalnemu sredstvu za obdobje sedmih dni. Merjeni mehanski parametri so vključevali maksimalno silo, natezno napetost, deformacijo in modul elastičnosti. Rezultati kažejo, da izpostavljenost hladilno-mazalnemu sredstvu bistveno vpliva na mehanske lastnosti, pri čemer so vzorci PLA+CF v povprečju ohranili boljšo mehansko odpornost v primerjavi s čistim PLA. Ti rezultati so pomembni za razumevanje obnašanja 3D-natisnjenih materialov v realnih industrijskih pogojih

Secondary title:	THE IMPACT OF THE ENVIRONMENT ON THE MECHANICAL PROPERTIES OF 3D PRINTED PROTOTYPES MADE FROM POLYMER MATERIALS AND COMPOSITES
Secondary abstract:	This thesis investigates the impact of a coolant-lubricant on the mechanical properties of 3D-printed prototypes made from PLA and carbon fiber-reinforced PLA (PLA+CF). The study examines samples with varying infill densities (20%, 40%, 60%, 80%, and 100%), comparing those that were unexposed to the coolant-lubricant with those that were exposed to it for a period of 7 days. The mechanical parameters measured include maximum force, tensile stress, strain, and modulus of elasticity. The results indicate that exposure to the coolant-lubricant significantly affects the mechanical properties, with the PLA+CF samples generally retaining superior mechanical resistance compared to pure PLA. These findings are crucial for understanding the behavior of 3D-printed materials under real-world industrial conditions.
