“…Gebisa and Lemu [12] demonstrated that the process parameters influence the tensile properties of high-performance ULTEM 9085 polymeric material printed via 3D FDM technique. Harshitha and Rao [13] combined PLA and ABS for the 3D FDM printing of a nut and a bolt, the structural analysis was performed using the ANSYS commercial code. The PLA as well as ABS bolts were correlated with each other and evaluated.…”

In this paper, polymeric specimens are produced via the Fused Deposition Modelling (FDM) technique. Then, experimental tensile and compression tests are conducted to evaluate the main mechanical properties of elements made of PolyLacticAcid (PLA) material. A standardized characterization test method for FDM 3D printed polymers has not been developed yet. For this reason, the ASTM D695 (usually employed for polymers produced via classical methods) has been here employed for FDM 3D printed polymers after opportune modifications suggested by appropriate experimental checks. A statistical analysis is performed on the geometrical data of the specimens to evaluate the machine process employed for the 3D printing. A capability analysis is also conducted on the mechanical properties (obtained from the experimental tests) in order to calculate acceptable limits useful for possible structural analyses. The Young modulus, the proportional limit and the maximum strength here defined for PLA specimens allow to confirm the different behavior of FDM printed PLA material in tensile and compressive state. These differences and the calculated acceptable limits for the found mechanical properties must be considered when this technology will be employed for the design of small structural objects made of PLA, as in the present study, or ABS (Acrilonitrile Butadiene Stirene). From the statistical and capability analysis, the employed printing process appears as quite stable and replicable. These types of research together with other similar ones that will be conducted in the future will allow to use polymeric materials and the FDM technique to produce small structural elements and also to carry out the appropriate verifications.

“…Gebisa and Lemu (2019) analyzed these influences by means of a full factorial design of experiment. Harshitha and Rao (2019) employed PolyLacticAcid (PLA) and Acrylonitrile Butadiene Styrene (ABS) materials to product a nut and a bolt by means of the FDM 3D printing technology, the commercial ANSYS software was employed for the finite element structural analysis. PLA and ABS were compared with Nylon 6 in the study by Lay et al (2019) where physical and mechanical performances were investigated when fused deposition modeling and conventional injection molding processes were used.…”

In recent years, the 3D Fused Deposition Modelling (FDM) technology, usually employed for the production of nonstructural objects, has been also used by the present authors for the production of small structural elements where the applied loads are moderate. A typical application could be the production of small Unmanned Aerial Vehicles (UAVs) where stresses are not excessive. In these cases, the FDM technique can use polymers such as Acrylonitrile Butadiene Styrene (ABS) and PolyLacticAcid (PLA). The present work is an extension of a past authors' work where some sandwich configurations were proposed combining different materials (ABS or PLA) and different cores (homogeneous or honeycomb). In the present study, only PLA specimens embedding honeycomb cores are analyzed in order to understand if this selected lamination scheme could lead to an important weight reduction without significant decreases of mechanical properties. A capability analysis is performed on the geometrical parameters of the specimens (also comprising the weight) in order to investigate the stability of the printing process. A three-point bending test is conducted to evaluate the linear bending Young modulus and the ultimate bending stress. These mechanical properties are post-processed in order to conduct a capability analysis to propose the upper and lower specification limits to be used with confidence in appropriate structural analyses.

Después de ingresar las constantes elásticas del material se procede a realizar las simulaciones correspondientes al ensayo de tensión y compresión [27]. Del estudio de tensión del material se obtuvo: deformación total (Fig.…”

En este artículo se presentan los resultados de la caracterización del material obtenido en impresión 3D compuesto por poliuretano termoplástico, en donde se seleccionó este material ya que fue el más adecuado para la fabricación de un dispositivo que absorba y disperse la energía. Adicionalmente, se adecuo a una chaqueta que con el propósito de usarlo en la disciplina de ciclismo. En el diseño se tuvo en cuenta diferentes tallas a medida del usuario y un proporcionado ajuste al codo, en donde se recibe la mayor energía de impacto. Se determinó la resiliencia del material polimérico a los que se les vario la estructura interna de relleno, dejando como variable fija la densidad de rellenado. El tipo de estructura interna del material con mayor energía almacenada antes de la deformación plástica fue el poliuretano termoplástico con rellenado cúbico, con el software ANSYS se determinó el comportamiento a comprensión y a tensión de la estructura
