Applications of additive manufacturing at selected South African universities: promoting additive manufacturing education
(Emerald, 2019)Purpose This paper aims to provide a comprehensive overview of the recent applications of additive manufacturing (AM) research and activities within selected universities in the Republic of South Africa (SA). Design/ ... -
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 ... -
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. ... -

Framework for effective additive manufacturing education: a case study of South African universities
(Emerald, 2019)Purpose In this era of Fourth Industrial Revolution, also known as Industry 4.0, additive manufacturing (AM) has been recognized as one of the nine technologies of Industry 4.0 that will revolutionize different sectors ... -
Insights into emissions and exposures from use of industrial-scale additive manufacturing machines
(Elsevier, 2019)Background Emerging reports suggest the potential for adverse health effects from exposure to emissions from some additive manufacturing (AM) processes. There is a paucity of real-world data on emissions from AM machines ... -
Non-destructive, high-resolution X-ray micro-CT of a Hairy Stalagmite: investigating the structural details of a biogenic speleothem
(Springer, 2018)Three-dimensional X-ray micro-computed tomography permits to investigate the internal structure of objects at a high resolution without altering its original form. It also facilitates the rendering and visualization of a ... -
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 ...
