20.500.12556/RUL-181980 The Durability of 3D-printed furniture connectors made from different materials The use of 3D-printed parts is becoming increasingly widespread, including in the furniture industry. Furniture products are subjected to various loads during use. Therefore, it is important to know their maximum allowable static loads and their maximum allowable cyclic loads, which are lower and depend on design and material properties. In this study, simple 3D FFF printed connectors intended as shelf connectors and made of three different materials (ABS, PLA, Wood–PLA) were subjected to different forces under static and cyclic loading until failure. Connectors made of ABS withstand the highest static load (346 N), followed by connectors made of PLA (195 N) and Wood–PLA (136 N). The fatigue behaviour of the tested connectors also depended on the material used. Connectors made of ABS exhibit the highest static load, but the stresses must be significantly lower under cyclic loading. For example, connectors made of ABS can withstand 50,000 cycles with a load of less than 25% of their maximum static load, while connectors made of PLA can withstand the same number of cycles with a load of 44% of their maximum static load. Connectors made of Wood–PLA achieved 50,000 cycles at a load of 63% of their maximum load. PLA and Wood–PLA were more durable relative to their maximum strength, even though ABS could carry heavier absolute loads. These findings could support the design of material-efficient furniture connectors with respect to their expected maximum loads and required durability; however, the results should be interpreted as preliminary and indicative of comparative trends rather than statistically validated fatigue data. 3D printing furniture connector fatigue durability 3D tiskanje pohištveni veznik utrujanje materiala utrujanje materiala true false true Angleški jezik Slovenski jezik Članek v reviji 2026-04-21 13:42:21 2026-04-21 13:42:27 2026-04-22 04:28:34 0000-00-00 00:00:00 2026 0 0 14 str. iss. 8, [article no.] 4016 Vol. 16 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8 2076-3417 10.3390/app16084016 275971587 RAZ_Kariz_Mirko_2026.pdf RAZ_Kariz_Mirko_2026.pdf 1 8AA8B29BEF7348CDD0C099C77490A6FA 69362156d54c14082183140db9272b7fa5e0456929c86ed035b2c37ab88af89e 391f9a57-3d77-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232828 https://www.mdpi.com/2076-3417/16/8/4016 1 eeb22aed-3d76-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232827 Biotehniška fakulteta 0 0 0
