The role of 3D-printed products in both daily use and industrial applications has been progressively reinforced. Plastic materials undergo physical and chemical changes when exposed to environmental conditions such as temperature, light, and humidity. Consequently, they are subjected to aging during use, which shortens their service life. With the expanding use of 3D printing technology in various sectors such as healthcare, automotive, aerospace, and defense, it has become increasingly important to understand the changes (potential decreases or losses) in the performance of these materials after long-term exposure to environmental conditions. This study aims to contribute to the understanding of potential changes in 3D-printed ABS Plus material by examining the phenomenon of aging induced by exposure to radiation from a xenon arc lamp. ABS Plus samples of different colors (yellow, purple, red, green, and blue) were subjected to aging for 0, 112, 225, 337, and 450 h using a xenon arc lamp. To investigate the effects of aging, the mechanical (tensile, flexural, and hardness) and optical (color and gloss variations) properties of the samples were compared before and after aging. Following the mechanical tests, the fracture modes of the specimens were also examined. In addition, Scanning Electron Microscope (SEM) images were obtained to further discuss the effects of aging. The results revealed that the mechanical properties of the reference samples varied depending on color. The highest tensile strength was observed in the yellow samples (33.46 MPa), while the highest flexural strength was recorded in the green samples (58.46 MPa). After aging, the lowest tensile strength was found in the purple samples aged for 337 h (24.63 MPa), whereas the lowest bending force was measured in the red samples aged for 450 h (45.27 N). Overall, the mechanical properties of the samples varied with aging duration, with the blue and green specimens being the least affected. For the blue specimens, after 112, 225, and 337 h of aging, an increase in tensile strength was observed (2.77%, 10.54%, and 9.58%, respectively), while a decrease occurred after 450 h of aging (\u22126.22%). For the green specimens, after 112, 225, and 337 h of aging, the tensile strength remained similar to that of the reference sample (\u22122.97%, 0.23%, and 0.05%, respectively) but decreased after 445 h of aging (\u22128.09%). In terms of optical properties, the most significant color change (\u221223.51) was observed in the purple samples. Gloss measurements indicated that the impact of aging increased with exposure time.<\/jats:p>","DOI":"10.3390\/polym17212940","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T14:00:33Z","timestamp":1762178433000},"page":"2940","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Investigation of the Mechanical and Optical Properties of ABS Plus Materials in Different Colors After Aging"],"prefix":"10.3390","volume":"17","author":[{"given":"Muhammet","family":"Akyol","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Zonguldak B\u00fclent Ecevit University, Zonguldak 67100, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6738-9741","authenticated-orcid":false,"given":"Nergizhan","family":"Ana\u00e7","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Zonguldak B\u00fclent Ecevit University, Zonguldak 67100, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1928-4301","authenticated-orcid":false,"given":"O\u011fuz","family":"Ko\u00e7ar","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Zonguldak B\u00fclent Ecevit University, Zonguldak 67100, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2767-8722","authenticated-orcid":false,"given":"Erhan","family":"Baysal","sequence":"additional","affiliation":[{"name":"Alapl\u0131 Vocational School, Zonguldak B\u00fclent Ecevit University, Zonguldak 67850, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3997-8690","authenticated-orcid":false,"given":"\u0130rfan","family":"Akg\u00fcl","sequence":"additional","affiliation":[{"name":"Scientific and Technological Research Center, Duzce University, Duzce 81620, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,3]]},"reference":[{"key":"ref_1","unstructured":"King, L.
