Analysis of Ageing and Degradation Behavior of Polyamide-12 for Sustainable Additive Manufacturing
Abstract: Additive Manufacturing (AM), particularly High-Speed Sintering (HSS), has emerged as a transformative technology capable of producing complex thermoplastic parts with high efficiency and minimal material waste. The HSS process involves selective deposition of radiation-absorbing ink followed by infrared heating to consolidate polymer powders-most commonly polyamide-12 (PA12). While PA12 is widely used due to its excellent thermal stability and mechanical properties, the sustainability of HSS strongly depends on the reuse of …

Study of pH Behaviour of Slurry on Surface Morphology of Copper Material with Single Pole Magnetic Abrasive Finishing Process
Abstract: The chemical oxidizers—sodium hydroxide, Marshall’s acid salt, and hydrogen peroxide—were effectively employed in the wet polishing of copper using the SPMAF experimental setup. The manuscript explores preparation of slurry used for polishing copper material using single pole magnetic abrasive finishing (SPMAF) framework. The slurry contains distilled water, 1200-grit aluminum oxide abrasives, sodium hydroxide (NaOH), potassium persulfate (K₂S₂O₈), and hydrogen peroxide (H₂O₂), combined in precise amount. Specifically, 100 ml of distilled …

Microstructure Analysis and Material Properties of Weld Slag as Fine Aggregate in Concrete
Abstract: To reduce the amount of river sand used, researchers and engineers have developed their own solutions. The well-known technique of submerged-arc welding can create high-quality welds in a variety of thicknesses for ferrous, stainless, and even some non-ferrous metals. The procedure involves an electric current flowing constantly between a welding wire and the work piece, creating an arc. In submerged arc welding, the shielding flux is transformed into slag during …

Fabrication and Characterization of Almond Skin Powder Reinforced PLA Based Composite Filaments for Fused Filament Fabrication
Abstract: Researchers around the globe are increasingly utilizing recycling methods to address waste generated from polymers, spurred by the dire need to deal with environmental challenges promoting sustainable practices. Polymers are having highly-stable long-chain polymer structure which makes it difficult to degrade easily posing many environmental and health challenges, hence, recycling of the polymers is the sole method to mitigate harmful effects. However, there has been relatively little focus on producing …

A Strategy of Nano-Calcite Fillers for Enhancing the Mechanical and Thermal Properties of Polypropylene Polymers
Abstract: Particulate polymer composites have gained popularity because of their many uses. For some, using high loadings to achieve desired attributes without compromising the material's mechanical properties or restricting its processability is desirable. It is possible to use surface active agents to improve characteristics and increase solid loading. Interface characteristics in highly packed particulate composites based on nano-calcite (nano-calcium carbonate) and polypropylene as a binder are the focus of the current …

Experimental Studies on the Mechanical and Microstructural Properties of Sustainable Concrete Incorporating Palm Oil Industrial Waste
Abstract: Diving into the world of concrete, normal concrete is widely used in construction but poses environmental challenges due to significant carbon dioxide emissions from cement production. Incorporating oil palm shells (OPS) and palm oil fuel ash (POFA) into concrete offers a sustainable alternative, utilizing waste products from the palm oil industry and reducing environmental impact. Experimental studies have examined the use of OPS and POFA as partial replacements for coarse …
