“…Yield stress was 21% higher, whereas Young's Modulus was 17% greater and tensile strength at the break point was only 20% higher in the injected samples. Comparing FDM and IM, Lay et al obtained similar results [18], while Blok. et al tested a printed short carbon fibre-reinforced nylon (6 wt % of fibre weight content) and reported a UTS = 33 MPa and E = 1900 MPa [9].…”

“…Nylon 6 showed a tensile strength of~80 MPa vs.~50 MPa for PLA and~65 MPa for ABS considering injected parts. In the case of AM manufactured parts, lower results were obtained: a tensile strength of~50 MPa for nylon 6,~45 MPa for PLA and~25 MPa for ABS [18].…”

“…Higher stiffness and strength values are obtained in PA6 than in PA12, which is more widely used in FDM research, considering the limitations on the melting temperature according to the thermal resistance of printed parts [17]. Other materials, such as ABS and PLA, have been compared to PA, but have yielded worse results [18]. Nylon 6 showed a tensile strength of~80 MPa vs.~50 MPa for PLA and~65 MPa for ABS considering injected parts.…”

New technologies are offering progressively more effective alternatives to traditional ones. Additive Manufacturing (AM) is gaining importance in fields related to design, manufacturing, engineering and medicine, especially in applications which require complex geometries. Fused Deposition Modelling (FDM) is framed within AM as a technology in which, due to their layer-by-layer deposition, thermoplastic polymers are used for manufacturing parts with a high degree of accuracy and minimum material waste during the process. The traditional technology corresponding to FDM is Polymer Injection Moulding, in which polymeric pellets are injected by pressure into a mould using the required geometry. The increasing use of PA6 in Additive Manufacturing makes it necessary to study the possibility of replacing certain parts manufactured by injection moulding with those created using FDM. In this work, PA6 was selected due to its higher mechanical properties in comparison with PA12. Moreover, its higher melting point has been a limitation for 3D printing technology, and a further study of composites made of PA6 using 3D printing processes is needed. Nevertheless, analysis of the mechanical response of standardised samples and the influence of the manufacturing process on the polyamide’s mechanical properties needs to be carried out. In this work, a comparative study between the two processes was conducted, and conclusions were drawn from an engineering perspective.

“…The nal cost is reduced due to machine and material low cost, but the process shows some limitations [47], as laments such as PLA and ABS vary in material composition, porosity, and environmental stability. Although no mechanical tests were performed with the 3D printed face shields in this study, it is known that mechanical properties such as tensile strength, Young's modulus, elongation at break, and impact strength are lower in an object that is manufactured under FDM process compared with the ones under the IM process [48]. However, the mechanical stress that a face shield receives is extremely low, and although the facial protector produced by IM has better quality, both have a comparable functionality level.…”

Face shields have been adopted worldwide as personal protective equipment for healthcare professionals during the COVID-19 pandemic. This device provides a transparent facial physical barrier reducing the exposure to aerosol particles. The fused deposition modeling (FDM) is the most applied process of additive manufacturing due to its usability and low-cost. The injection molding (IM) is the fastest process for mass production. This study is the first to perform a qualitative comparison between the use of FDM and IM processes for mass production and rapid distribution of face shields in a pandemic. The design of the face shield and tests were conducted in prototyping cycles based on requirements of medical, Brazilian standards, manufacturing, and production. The FDM face shields manufacturing was carried out by a volunteer network, and the IM manufacturing was carried out by companies. The volunteers produced 35,000 medical face shields through the FDM process with daily delivery to several hospitals. A total of 80,000 face shields was produced by the IM process and delivered to remote Brazilian regions. The mass production of 115,000 face shields protected health professionals from public hospitals in all states of Brazil. In a pandemic, both FDM and IM processes are suitable for mass production of face shields. Once a committed network of volunteers is formed in strategic regions, the FDM process promotes a fast daily production. The IM process is the best option for large scale production of face shields and delivery to remote areas where access to 3D printing is reduced.

“…Another study involved that; polydopamine coated recycled PLA materials to be reused involving mechanical behaviour so as economize the use of PLA [10]. Including CNT along with PLA shows a significant effect on crystallization MRF and Melting rate [11] and decreased percentage of density rate [12] is observed along with recycled PLA [13] used through the process of FDM additive manufacturing technique. So the present work is focused on studying the mechanical properties of different fill percentage accordingly as well as cost-efficient.…”

Abstract: Additive Manufacturing termed by ASTM standard referred to in short as, the technology of fabricating a model based on creating a three-dimensional Computer-Aided Design structure. In the context of developing a product from digital data directly, widely involved various technologies. Amongst them, one being Fused Deposition Modelling (FDM) which supervises the principle of AM, is widely known for developing a polymer-constructed sturdiest range of materials or parts are having operative mechanical properties. Even though, the main problem exaggerates that, the quality of the output still denies due to which void parts are created from bubbles trapped leading to failure of parts under mechanical stresses. Since with 15% infill, stronger parts are estimated and their mechanical properties are studied. Since the work signifies the influence of 15% infill on mechanical properties in estimating stronger products by layered addition process. The experimental methodology is based on structural infill parameters determining goal in achieving and studying material mechanical properties.
