description 4340 steel powders were processed with an additive manufacturing process using the FFF (Fused Filament Fabrication) technique. A composite filament was developed to print samples and study the effect of the bed and nozzle temperatures on its physical and microstructural properties. The printed samples were debinded and sintered by: Solid State (SS) at 1300 °C or SLPS (Supersolidus Liquid Phase Sintering) at 1420 °C. Metallography and scanning electron microscopy (SEM) identified the microstructure and phases. The hardness of the sintered samples was measured with the Vickers method. The SLPS process contributes to better densification and volume contraction; however, it promotes geometrical distortion of the samples compared to the SS samples. The microstructure of the sintered samples consists of ferrite situated in the original austenite grain and bainite. The sintering mechanism significantly influenced the hardness of the samples. Finally, a part was designed, printed, debinded, and sintered with the aim of studying the maximum inclination angle, the minimum vertical and horizontal holes, and the minimum vertical layer thickness, which can be obtained through the whole process.

Se desarrolló un filamento compuesto para imprimir muestras y estudiar el efecto de la temperatura de la cama y de la boquilla de impresión en sus propiedades físicas y microestructurales. Las muestras impresas fueron despolimerizadas y sinterizadas en estado sólido (Solid State - SS) a 1300 °C y sinterización en fase líquida super solidus (Supersolidus Liquid Phase Sintering -SLPS) a 1420 °C. Por metalografía y microscopía electrónica de barrido (SEM) se identificó la microestructura y las fases presentes. La dureza de las muestras sinterizadas se midió con el método Vickers. El proceso SLPS contribuye a una mejor densificación y contracción volumétrica; sin embargo, promueve distorsión geométrica de las muestras en comparación con las muestras SS. La microestructura de las muestras sinterizadas consiste en ferrita situada en el límite de grano austenítico original y bainita. El mecanismo de sinterización influyó significativamente en la dureza de las muestras. Finalmente, se diseñó, imprimió, despolimerizó y sinterizó una pieza con el objetivo de estudiar el ángulo máximo de inclinación, los mínimos agujeros verticales y horizontales, y el mínimo espesor de capa vertical, que se pueden obtener a lo largo de todo el proceso.application/pdfengengUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/13913/11715Copyright (c) 2022 Andres-Fernando Gil-Plazas, Julián-David Rubiano-Buitrago, Luis-Alejandro Boyacá-Mendivelso, Liz-Karen Herrera-Quinterohttp://creativecommons.org/licenses/by/4.0http://purl.org/coar/access_right/c_abf294http://purl.org/coar/access_right/c_abf2Revista Facultad de Ingeniería; Vol. 31 No. 60 (2022): April-June 2022 (Continuous Publication); e13913Revista Facultad de Ingeniería; Vol. 31 Núm. 60 (2022): Abril-Junio 2022 (Publicación Continua); e139132357-53280121-1129Additive manufacturing4340 steeldebindingsinteringcharacterizationfused filament fabricationacero 4340caracterizacióndespolimerizadofabricación de filamentos fundidosmanufactura aditivasinterizaciónSolid-State and Super Solidus Liquid Phase Sintering of 4340 Steel SLM Powders Shaped by Fused Filament FabricationSinterización en fase líquida super solidus y de estado sólido de polvos SLM de acero 4340 formados por fabricación de filamentos fundidosinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a377http://purl.org/coar/version/c_970fb48d4fbd8a85Gil-Plazas, Andres-FernandoRubiano-Buitrago, Julián-DavidBoyacá-Mendivelso, Luis-AlejandroHerrera-Quintero, Liz-Karen001/14332oai:repositorio.uptc.edu.co:001/143322025-07-18 11:53:44.349metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
