Additive manufacturing in South Africa: building on the foundations

Abstract

Type of Paper General Review PurposeIn a previous Rapid Prototyping Journal paper, the authors reviewed the first decade of Rapid Prototyping (RP) use within the Republic of South Africa (RSA). The paper analysed its strengths, weaknesses, opportunities and threats, and proposed a "road-map" for future development. Much has happened in the intervening years since that article was published and this paper seeks to update readers on the current situation in RSA. In particular, it reports the extensive development of research in the field of RP and Additive Manufacturing (AM). MethodologyThe paper uses a literature review approach combined with reflective analysis to distill the most important developments within the RP community in RSA since 2004. These are compared to the previous road-map to ascertain if there are any required actions that have been overlooked or any additional lessons that have been learnt. FindingsThe paper shows that there has been good progress against the previous road-map and that current plans should remain in place with the addition of a greater educational dimension. Practical ImplicationsThis paper provides readers with an overview of important RP/AM developments in the RSA.The analysis from this the paper will aid RSA academics, industrialists and government agencies to assess their performance and to plan for their future roles within the RP community. ValueAs with the previous paper, this article provides a useful model for other countries to follow since it demonstrates both good practice but also the need to learn from past experience.

Advances In Ti6Al4V Additive Manufacturing in South Africa

“…The history and growth of the technology was described by De Beer [4] and Campbell, De Beer and Pei [5]. Figure 1 shows the acceleration in the acquisition of AM systems in South Africa since 2010, after the first years of slow growth.…”

Weaknesses in policy to support technology diffusion: a study of additive manufacturing in South Africa

“…Existing literature suggested that the technology was being applied but only at an experimental level but the studies themselves offered little insight into the factors preventing the use of AM as a means of transforming the manufacturing sector (Campbell and De Beer and Pei, 2011). In this study the following research questions were explored in order to provide this insight:…”

Physical Modelling of Terrain Directly From Surfer Grid and Arc/Info Ascii Data Formats#

“…AM technology has also been used to fabricate architectural models [12,7]. Campbell et al [4] have reviewed the use of AM technology for terrain modelling, architectural modelling, and other applications in South Africa.…”
