Development of a non-destructive testing method to determine the tensile fatigue life of Ti-6Al-4V additively manufactured parts
(North-West University (South Africa), 2020)Direct metal laser sintering (DMLS) is a powder bed fusion (PBF) technology used for additive manufacturing (AM). This process deploys a laser to selectively fuse regions of a powder bed. The manufacturing of a part is ... -
Effect of powder characteristics and layer thickness on the densification of Selective Laser Melted CoCrMo
(North-West University (South Africa)., 2023)Selective laser melting (SLM) is a metal additive manufacturing (AM) process that fabricates parts according to a CAD design in a layer-by-layer fashion by melting metal powder. There are a vast number of powder-related ... -
Efficacy of the distortion compensation method for Selective Laser Melting specimens
(North-West University (South Africa)., 2022)As industry 4.0 has gained momentum, the need for accurate, fast, and customizable component prototyping and fabrication has risen drastically. Additive manufacturing provides the freedom and capability to fabricate complex ... -
Evaluation of carbon fibre powder scrapers used in metal additive manufacturing
(North-West University (South-Africa). Potchefstroom, 2019)Powder Bed Fusion (PBF) is an Additive Manufacturing process which builds parts, layer by layer, by melting the cross-section of the part onto a powder layer. Aeroswift is a PBF machine, designed and built in South Africa. ... -

A maturity model to enhance the adoption of Additive Manufacturing in spare part provisioning in South Africa
(North-West University (South Africa)., 2022)The fourth industrial revolution (4IR) demands a significant change in the way businesses operate. The previous three industrial revolutions were initiated from the market and demanded that organisations adopt to the ... -
Particulate emissions and respiratory exposure to hazardous chemical substances during additive manufacturing of sand moulds
(North-West University (South-Africa), 2021)Background: AM (Additive Manufacturing) is a process that produces three-dimensional (3D) parts via the layering of materials. To date, there has been little research on the health risks associated with the use of this ... -
Respiratory exposure during the additive manufacturing of sand casting moulds
(North-West University (South Africa) , Potchefstroom Campus, 2016)Background: During additive manufacturing (AM) of sand casting moulds, potential dust species of unknown particle size or mineral composition, and hazardous chemical substances (HCS’s) such as silica (crystalline), volatile ... -
Viability of 3D fused filament fabrication for aerospace applications
(North-West University (South Africa), 2021)This study investigates the possible utilization of modern three-dimensional (3D) fused filament fabrication (FFF) in engineering applications. These FFF machines use filament that are usually made from PLA or ABS, coiled ...
