20.500.12556/RUL-154925 Environmental assessment/evaluation of 3D printing and 3D printing with wood-PLA composites case study Ekološka procjena/evaluacija 3D printanja i 3D printanja s drvo-PLA kompozitima studija slučaja In recent years, additive manufacturing has become a regular process in various industries, and consequently there is an increasing need to evaluate the environmental aspects of this technology and its associated materials. In this paper, comparative cradle-to-grave life cycle assessments between a conventional product and a 3D-printed alternative made of polylactic acid (PLA) and PLA-wood material were investigated based on the standard ISO 14044:2006. The environmental impact of each product was quantified for 18 categories. The goal of life cycle assessment (LCA) was to determine whether the use of 3D printed PLA/PLA-wood products can be a sustainable alternative to traditional metal products. The paper presents a case study in which a comparative LCA was conducted. The results show that a metal part manufactured using conventional subtractive processes (milling, drilling, welding, etc.) has a higher environmental impact compared to 3D-printed alternatives made from renewable materials. However, there are many sub-issues that need to be adequately addressed. life cycle assessment 3D printing environmental impact carbon footprint wood-PLA composite ocena življenjskega cikla 3D tiskanje vplivi na okolje ogljični odtis lesno-plastični kompozit true false true Angleški jezik Hrvaški jezik Članek v reviji 2024-03-09 03:51:04 2024-03-11 07:05:37 2024-03-28 14:58:55 0000-00-00 00:00:00 2024 0 0 Str. 49-58 iss. 1 Vol. 75 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 674.816 0012-6772 10.5552/drvind.2024.0107 188161283 RAZ_Krapez_Tomec_Dasa_2024.pdf RAZ_Krapez_Tomec_Dasa_2024.pdf 1 B40B27CA9409F2FBE426A2DE319937B0 f00e461ab7a732ea84ff6877da1b750c5b88a10ba47140d057bf5b46eacfa6b0 e61ae63f-df6d-11ee-a66a-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181593 https://hrcak.srce.hr/clanak/454791 1 e2a079e5-ddbf-11ee-85f5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181580 Biotehniška fakulteta 0 0 0
