An extensive quarrying of stone leads to the accumulation of mineral residues, posing environmental hazards by contaminating soil and water when disposed of in landfills. The primary objective of the study was to incorporate mineral waste into the SLS technique and investigate the influence of its addition, along with a silane-based chemical treatment, on the mechanical performance of polymer-mineral composites (PA12-slate). Additionally, the feasibility of producing a highly loaded printed prototype, employing 50 wt% of mineral waste, was examined. Samples of PA12, PA12 blended with 50 wt% slate waste, and slate waste treated with silane underwent fabrication via selective laser sintering (SLS) and subsequent mechanical characterization, including tensile, flexural, and compressive tests. Additionally, the samples underwent accelerated aging using a QUV weathering tester, followed by mechanical characterization. The geometric accuracy, stability, and processing feasibility of these formulations were evaluated through SLS-printed composite prototypes utilizing PA12_50Sla_Si. It was found that the addition of 50% of slate to the PA12 presented mechanical properties decreasing compared to the printed PA12 only. However, an increase was verified when using silane-induced mineral bonding. The incorporation of mineral agents and silane enhanced the resistance of PA12 to aging. However, after aging, both tensile and flexural strength decreased across all printed samples. Nonetheless, this study showcased the feasibility of producing complex PA12-slate waste specimens containing up to 50 wt% of mineral waste using the SLS printing technique. Therefore, SLS presents itself as a viable means of adding value to this mineral waste.<\/jats:p>","DOI":"10.1007\/s00170-024-13989-8","type":"journal-article","created":{"date-parts":[[2024,8,2]],"date-time":"2024-08-02T04:12:33Z","timestamp":1722571953000},"page":"2979-2992","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Enhancing mechanical performance in SLS-printed PA12-slate composites through amino-silane treatment of mineral waste"],"prefix":"10.1007","volume":"134","author":[{"given":"Lu\u00eds","family":"Nobre","sequence":"first","affiliation":[]},{"given":"Daniel","family":"Barros","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o","family":"Bessa","sequence":"additional","affiliation":[]},{"given":"Fernando","family":"Cunha","sequence":"additional","affiliation":[]},{"given":"Michael","family":"Machado","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o P.","family":"Mendon\u00e7a","sequence":"additional","affiliation":[]},{"given":"Jorge","family":"Lu\u00eds","sequence":"additional","affiliation":[]},{"given":"Martinho","family":"Oliveira","sequence":"additional","affiliation":[]},{"given":"Paulo","family":"Machado","sequence":"additional","affiliation":[]},{"given":"C\u00e9sar","family":"Fernandes","sequence":"additional","affiliation":[]},{"given":"Raul","family":"Fangueiro","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,8,2]]},"reference":[{"key":"13989_CR1","doi-asserted-by":"publisher","first-page":"196","DOI":"10.1016\/j.jmst.2021.03.058","volume":"94","author":"A Nouri","year":"2021","unstructured":"Nouri A, Shirvan A, Li Y, Cuie W (2021) Additive manufacturing of metallic and polymeric load-bearing biomaterials using laser powder b e d fusion: a review.
