Manufacturing high-value materials often yields excessive waste, high costs, and lengthy lead times using traditional methods. Directed Energy Deposition (DED) offers a sustainable alternative by reducing material waste, machining time, and tool consumption.

During L-PBF digital build job preparation, enabling assignment of process parameters of individual laser vectors, offers a pathway to mitigate lack of fusion defects by controlling the solidified melt pool dimensions of welding tracks. For this study geometries designed to induce significant variations in thermal history were printed to demonstrate

Functionally graded materials (FGMs) offer significant potential for the tool and die industry, but limited research explores their use combining stainless steel and tool steel via additive manufacturing. This study focussed on immediate FGMs by using wire laser-based directed energy deposition to join H12 tool steel to 316 L stainless

This study examined the application of two additive manufacturing (AM) technologies, namely Directed Energy Deposition (DED) and Laser Powder Bed Fusion (L-PBF), within the oil and gas industry with a special focus on the African context.

Metal additive manufacturing has emerged as a promising technology with vast potential in the oil and gas industry. The Nigerian National Petroleum Company (NNPC) Limited recognizes the significance of this technology and has initiated efforts to adopt metal additive manufacturing within its operations. This paper aims to provide an overview

Nitinol shape memory alloys are used in a wide range of biomedical applications because of their biocompatibility, shape memory and superelasticity properties, and high corrosion resistance. Processing NiTi using additive manufacturing has led to even wider possibilities for use in the biomedical field. The focus of the study was on

The oil and gas industry in Africa is under mounting pressure to elevate operational efficiency and curb costs, even as supply chain challenges stemming from the pandemic persist. Additive manufacturing (AM) emerges as a unique solution with the potential to free segments of the industry from conventional supply chains. This

Laser directed energy deposition technology using 309L welding wire feedstock was investigated in this research work. The aim of the study was to determine the effect of laser power and scanning speed on the microstructure and hardness of the 309L austenitic stainless steel. The travel speed and the laser power
