    Cost-effective fully 3D-printed on-drop electrochemical sensor based on carbon black/polylactic acid: a comparative study with screen-printed sensors in food analysis

    3D-printing technology allows scientist to fabricate easily electrochemical sensors. Until now, these sensors were designed employing a large amount of material, which increases the cost and decreases manufacturing throughput. In this work, a low-cost 3D-printed on-drop electrochemical sensor (3D-PES) was fully manufactured by fused filament fabrication, minimizing the number of printing layers. Carbon black/polylactic acid filament was employed, and the design and several printing parameters were optimized to yield the maximum electroanalytical performance using the minimal amount of material. Print speed and extrusion width showed a critical influence on the electroanalytical performance of 3D-PES. Under optimized conditions, the fabrication procedure offered excellent reproducibility (RSD 1.3% in working electrode diameter), speed (< 3 min/unit), and costs (< 0.01 $ in material cost). The 3D-PES was successfully applied to the determination of phloridzin in apple juice. The analytical performance of 3D-PES was compared with an equivalent commercial on-drop screen-printed electrode, yielding similar precision and accuracy but lower sensitivity. However, 3D-PES provides interesting features such as recyclability, biodegradability, low-cost, and the possibility of being manufactured near the point of need, some of which meets several demands of Green Chemistry. This cost-effective printing approach is a green and promising alternative for manufacturing disposable and portable electroanalytical devices, opening new possibilities not only in on-site food analysis but also in point-of-care testing.

    Analysis of General and Specific Standardization Developments in Additive Manufacturing From a Materials and Technological Approach
    (IEEE Xplore, 2020-06-25) García Domínguez, Amabel; Claver Gil, Juan; Sebastián Pérez, Miguel Ángel; Camacho López, Ana María
    Additive manufacturing processes and products are very present in the current productive landscape, and in fact these technologies have been one of the most intensively studied and improved during the last years; however, there is still no defined and homogeneous regulatory context for this field. In this work, a thorough review of the main general and specific regulatory developments in design, materials and processes standards for additive manufacturing has been carried out, with special attention to the standards for mechanical characterization of polymer-based products. In many cases standards developed for other productive contexts are identified as recommended references, and some contradictory trends can be identified when different documents and previous experiences are consulted. Thus, as it is logical considering that all these technologies are involved in an intensive and continuous evolution process, there is a certain lack of clarity regarding the standards to be considered. This work aims to contribute to clarify the current standardization context in additive manufacturing and provide some guidelines for the identification of appropriate standards. The paper also emphasizes that the key for next regulatory developments in mechanical testing is to develop standards that consider particular AM processes along with materials. Moreover, a great gap between available standard about additive technologies based on metallic materials and polymer materials during the last years has been detected. Finally, the provided overview is considered of interest as support for research and practice in additive manufacturing, and both in intensive productive scenarios and for particular users and makers.

    Últimas tendencias en el ámbito científico sobre procesos de fabricación aplicados a la construcción de aeronaves
    (Universidad Nacional de Educación a Distancia (España), Universidad Politécnica de Madrid. Departamento de Ingeniería Mecánica, 2022) Blanco, David; Sáenz De Pipaón, José Manuel; Rubio Alvir, Eva María; García Domínguez, Amabel; https://orcid.org/0000-0002-3776-5010
    La industria aeroespacial se ha centrado tradicionalmente en reducir la masa de las aeronaves mediante el uso de materiales estructurales ligeros, pero este tipo de materiales y los procesos de fabricación y mecanizado asociados están en continua evolución. Por ello, el presente estudio busca responder a la pregunta de cuáles son las últimas tendencias en procesos de fabricación y mecanizado orientados a la fabricación y ensamblaje de aeronaves. Para ello se realiza una revisión sistemática de la literatura científica asociada de los últimos 10 años, concluyendo la tendencia actual hacia el estudio de aleaciones de titanio, superaleaciones de níquel y aceros, incluidas en un 22%, 16% y 14% de los estudios respectivamente. También existe interés predominante por la fabricación aditiva presente en el 52% de los estudios, superior al 32% de estudios sobre fabricación sustractiva, revisándose ambas tecnologías y presentado los resultados en tablas resumen como soporte a investigadores interesados.
