The purpose of this work was to study the impact of printing strategies on the mechanical properties and predict mechanical behavior under tensile loading using finite element analysis. The testing of mechanical properties was conducted according to the ISO 527 standard. The numerical simulations were conducted in Simufact Forming 2022 software. Analysis of the experimental data showed a dependance of mechanical properties on the used printing strategy. The Clear PLA samples printed in the XY plane exhibited a 43% reduction in tensile strength and a 49% reduction in elongation compared to samples printed from the same material in YZ plane. The experimental results show the influence of the printing orientation on the mechanical properties of 3D-printed samples.<\/jats:p>","DOI":"10.3390\/polym15244639","type":"journal-article","created":{"date-parts":[[2023,12,7]],"date-time":"2023-12-07T10:45:33Z","timestamp":1701945933000},"page":"4639","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Experimental and Numerical Study of Printing Strategy Impact on the Mechanical Properties of Sustainable PLA Materials"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9377-714X","authenticated-orcid":false,"given":"Emil","family":"Spi\u0161\u00e1k","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering, Technical University of Ko\u0161ice, Letn\u00e1 9, 042 00 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ema","family":"Nov\u00e1kov\u00e1-Marcin\u010d\u00ednov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Technical University of Ko\u0161ice, Letn\u00e1 9, 042 00 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2742-8723","authenticated-orcid":false,"given":"Janka","family":"Majern\u00edkov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Technical University of Ko\u0161ice, Letn\u00e1 9, 042 00 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4176-3154","authenticated-orcid":false,"given":"Peter","family":"Mulidr\u00e1n","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Technical University of Ko\u0161ice, Letn\u00e1 9, 042 00 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u013dudmila","family":"Nov\u00e1kov\u00e1-Marcin\u010d\u00ednov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Manufacturing Technologies with a Seat in Pre\u0161ov, Technical University of Kosice, Bayerova 1, 080 01 Pre\u0161ov, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Rajak, D.K., Wagh, P.H., and Linul, E.
