Research page of Prof Anton du Plessis

This page describes my research, which is focused on Additive Manufacturing, X-ray tomography and Biomimicry. My specific interests in these domains and current research goals are highlighted below, please see recent publications for more information or contact me directly. I gladly collaborate and do contract research in areas overlapping strongly in these areas of expertise.

Additive manufacturing and specifically laser powder bed fusion (L-PBF) has reached a level of maturity where critical parts for aerospace and medical applications are being produced commercially. In this field I work on three aspects

  • Quality control: I work on new testing methods and improvements in processes which allow higher quality parts to be produced, pushing the adoption of additive manufacturing
  • Effect of defect: Here it is critical to understand the effect of various defect types to improve part quality and mechanical performance
  • Lattice structures & topology optimization: My aim here is to advance the use of lattices and topology optimization in practical applications.

X-ray tomography is an emerging materials analysis tool, which may be used in a wide variety of academic and industrial projects to image internal details of objects non-destructively. I push the frontiers of this technology for new applications, new methodologies and am especially interested in image based simulations.

Biomimicry or bio-inspiration can allow unique new materials designs based on nature’s lessons learned over millions of years of evolution. I focus on natural structures and attempt to learn “design rules” which can be applied to practical engineering applications.

 

Right now I am happy to announce that I will be hosting a special track “Biomimicry in AM” at the annual RAPDASA conference – the full first call and information on the special track is found here: RAPDASA 2019 – Announcment + 1st Call for Papers (brochure)

Please submit your work in any aspect of biomimetic engineering in additive manufacturing! Watch this space for invited speakers and more information!

 

I am academically associated with the Stellenbosch University Physics Department as Associate Professor, and also collaborate with various local and international groups.

My research work is supported by the Collaborative Program in Additive Manufacturing (CPAM) – I am very thankful for this support. Here is a 3D model of the CPAM logo for free download – designed in Altair Inspire and mesh simplified in VGSTUDIO MAX – click cpam highly simplified add stl extension to download 6 Mb STL file.

For students: we host MSc and PhD student projects. Currently we have no open positions but we aim to change that soon
For CT services, see our website below for the CT facility. For any other consulting (non CT services) please email me directly with your request, I gladly share my expertise in any of the above
