Resumo: | Additive manufacturing is growing rapidly in the automotive, medical, and aerospace industries as an option for the manufacturing of products. However, there is a continuous growth in the amount of waste generated by 3D filaments, thus, the reuse practice becomes important, since it brings environmental and economic gains. The present research evaluated the mechanical, thermal, thermomechanical and rheological properties of PLA/PLAr blends containing post-consumption 3D filament. The blends were prepared in a co-rotational twin screw extruder and, subsequently, the extruded granules were injection molded. As the PLAr content in the blends (PLA/PLAr) increased, there was a reduction in viscosity, indicating an improvement in manufacturability. The PLA/PLAr blend (75/25 % wt.) increased the degree of crystallinity compared to neat PLA, indicating that PLAr acted as a nucleating agent. As a consequence, the PLA/PLAr blend (75/25 % wt.) showed performance comparable to neat PLA in thermal stability, elastic modulus, tensile strength, Shore D hardness, impact strength, heat deflection temperature (HDT) and Vicat softening temperature. The reuse of post-consumption 3D filament PLA is feasible for the development of materials with good properties. In addition, value is added to the post-consumption material and there is a contribution to sustainable development. |

Sin embargo, existe un aumento creciente en el contenido de residuos generados por los filamentos 3D y, por tanto, la práctica de la reutilización se vuelve importante, ya que aporta beneficios medioambientales y económicos. La presente investigación evaluó las propiedades mecánicas, térmicas, termomecánicas y reológicas de mezclas de PLA/PLAr posconsumo de filamentos 3D. Las mezclas se prepararon en una extrusora de doble husillo rotacional y, posteriormente, los gránulos extruidos se moldearon por inyección. A medida que aumentó el contenido de PLAr en las mezclas (PLA/PLAr), hubo una reducción de la viscosidad, lo que indica una mejora en la procesabilidad. La mezcla de PLA/PLAr (75/25 % en masa) aumentó el grado de cristalinidad en comparación con el PLA virgen, lo que indica que el PLAr actuó como agente nucleante. Como consecuencia, la mezcla PLA/PLAr (75/25 % en masa) mostró un rendimiento comparable al PLA puro en estabilidad térmica, módulo elástico, resistencia a la tracción, dureza Shore D, resistencia al impacto, temperatura de deflexión térmica (HDT) y temperatura de ablandamiento Vicat. La reutilización de PLA de filamentos 3D postconsumo es factible para el desarrollo de materiales con buenas propiedades. Además, se agrega valor al material de posconsumo y se contribuye al desarrollo sostenible.A manufatura aditiva está crescendo de forma acelerada para a fabricação de peças nas indústrias automotiva, médica e aeroespacial. Porém, há um crescente aumento no teor de resíduos gerados pelos filamentos 3D e, portanto, a prática do reaproveitamento torna-se importante, uma vez traz ganhos ambientais e econômicos. A presente pesquisa avaliou as propriedades mecânicas, térmicas, termomecânicas e reológicas de blendas de PLA/PLAr pós-consumo de filamentos 3D. As blendas foram preparadas em uma extrusora de rosca dupla corrotacional e, posteriormente, os grânulos extrudados foram moldados por injeção. À medida que aumentou o teor de PLAr nas blendas (PLA/PLAr) houve uma redução na viscosidade, indicando um melhoramento na processabilidade. A blenda PLA/PLAr (75/25 % em massa) aumentou o grau de cristalinidade em comparação ao PLA virgem, indicando que o PLAr atuou como agente nucleante. Como consequência, a blenda PLA/PLAr (75/25 % em massa) apresentou desempenho equiparável ao PLA puro na estabilidade térmica, módulo elástico, resistência à tração, dureza Shore D, resistência ao impacto, temperatura de deflexão térmica (HDT) e temperatura de amolecimento Vicat. O reaproveitamento do PLA pós-consumo de filamentos 3D é viável para o desenvolvimento de materiais com boas propriedades. Além disso, agrega-se valor ao material pós-consumo e contribuindo para o desenvolvimento sustentável.Research, Society and Development2020-12-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1076710.33448/rsd-v9i12.10767Research, Society and Development; Vol. 9 No. 12; e13291210767Research, Society and Development; Vol. 9 Núm. 12; e13291210767Research, Society and Development; v. 9 n. 12; e132912107672525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/10767/9746Copyright (c) 2020 Wellerson Salomão Diniz Marinho; Carlos Bruno Barreto Luna; Edcleide Maria Araújo; Carlos Heitor de Andrade Lustosa; Celso Rosendo Bezerra Filho; Raimundo Nonato Calazans Duarte https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMarinho, Wellerson Salomão Diniz Luna, Carlos Bruno Barreto Araújo, Edcleide Maria Lustosa, Carlos Heitor de Andrade Bezerra Filho, Celso RosendoDuarte , Raimundo Nonato Calazans 2020-12-30T23:32:22Zoai:ojs.pkp.sfu.ca:article/10767Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:45.637807Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
