“…Various MCDM tools, such as BWM (Best Worst Method), AHP (Analytical Hierarchy Process), ANP (Analytical Network Process), COPRAS (COmplex PRoportional Assessment), TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution), FAHP (Fuzzy Analytical Hierarchy Process) and PROMETHEE (Preference Ranking Organization Method for Enrichment of Evaluations), are utilized. The decision-making process involves creating a pairwise matrix based on the decision maker's opinions, converting it into numerical values ranging from 0 to 9 (depending on the MCDM tool/technique) [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] . Subsequently, the pairwise matrix undergoes evaluation through fundamental steps like criteria weight determination, consistency ratio assessment, and random index calculation [58][59][60][61][62][63] .…”

The objective of this study is to investigate how the mechanical properties of components produced using acrylonitrile butadiene styrene (ABS) on a Creality Ender-3 3D printer are affected by various fused deposition modeling (FDM) printing parameters. The impact of various factors, including infill density, printing speed, platform temperature, extruder temperature, and so on, was assessed in terms of their influence on the ultimate tensile strength, yield strength, and elastic modulus of the manufactured components. The impact of each parameter was assessed using a Multi-criteria decision-making (MCDM) methodology. Finally, the second set of parameters, including a 35% infill thickness, 0.25 mm layer level, 40 mm/s printing speed, 75 °C platform temperature, 210 °C extruder temperature, and 75 mm/s travel speed, was discovered to be the most suitable for ABS filament used to make impellers.

“…Even though they have also been related to some environmental issues, the harm produced is less severe than petroleum-based plastic [36]. 3D printing or AM technologies like Fused Deposition Modeling (FDM) use plastics to build objects from 3D model data [8,41,42]. It joins thermoplastic filament layer upon layer until it forms the final object [37].…”

As climate change awareness increases, the worldwide interest in efficiently using resources, materials, and energy increases. From producers to consumers, the demand for sustainability-oriented processes has become stronger across all stock market sectors. Additive Manufacturing (AM) is a promising and relatively new manufacturing process that helps to overcome supply chain, logistics, and environmental issues that traditional processes face. Fortunately, AM can process different raw materials, such as glass, metal, ceramics, and plastics. Even though AM helps to reduce the use of the material in general, in the case of plastic, the environmental impact of their production and biodegradability remains an issue. As a response, plastics made from natural and renewable resources have become an alternative to the harmful conventional petroleum-based and no biodegradable plastics. Fortunately, there is evidence of products done through AM from these environmental-friendly plastics. The following review is intended to highlight (1) the opportunities and challenges for AM, (2) the comparison between bio and petroleum-plastic in 3D printing from a sustainability point of view, and (3) the economic and environmental benefits of this innovative combination of manufacturing processes and materials. This review provides a fundamental understanding and applied knowledge to create a new additive manufacturing platform based on renewable plant-based feedstocks.

“…In short, the premises of additive manufacturing, such as broadening the design envelope, just-in-time delivery, and efficient production, are manifested in reallife applications and facilitate the rapid translation of products from the bench to the market. [11,12] Like its predecessors, this scientific and industrial paradigm shift hinges on the ongoing development of hybrid and composite materials in different configurations, shifting the focus to reinforced cellular, syntactic solid structures such as honeycombs. [13] The ubiquity of cellular solids in engineering applications stems from the objective of mimicking nature-crafted and optimized structures in natural and biological materials, providing tunable geometries and properties, achieving unprecedented quasi-static and dynamic performances, and promising pathways to multifunctionality.…”

The proliferation of ordered cellular structures in industrial and technological applications is justified by their superior mechanical performance, including tunable energy absorption strategies and potential multifunctionality. This research evaluates the mechanical response of composite lattice structures fabricated using vat photopolymerization additive manufacturing process and printable particulate composite materials. Several generations of modified printable resins are prepared by hybridizing flexible resin with varying glass microballoons reinforcement weight percentages. Multifaceted characterization regiments highlight the process–property–performance interrelationship by submitting printed composite structures to quasi‐static and impact‐loading scenarios combined with digital stills and high‐speed photography, respectively. Image analyses of optical and scanning electron micrographs quantify the dimensional accuracy of the composite lattice structures with cylindrical and hexagonal cellular geometries. The mechanical characterization uncovers the effect of cell geometry and reinforcement on the global structural behavior, eliciting differences in load‐bearing capacity, local strain developments, and structural densification. Exploratory digital image correlation supports the global structural deformations, revealing their relationship with the developed local strain state within the unit cells. The outcomes of this research elucidate the effect of strain rate, unit cell geometry, and reinforcing ratios on the structural performance of composite lattice structures at the macro‐ and microstructure levels.
