Additive manufacturing (AM) has proven to be an attractive alternative manufacturing process compared with subtractive manufacturing (SM). Additive manufacturing has many advantages, such as mass customisation, less material wastage, and others listed in this article. However, the additive manufacturing of certified implants does not have the same degree of documentation and standardisation as the subtractive manufacturing process. As part of this research project, the problem statement is: “In offering additive manufacturing as an implant manufacturing solution, the complete process (design, manufacturing, and post-processing) had to be investigated in order to develop a certified manufacturing solution”.

Toevoegingsvervaardiging is ʼn aantreklike alternatiewe vervaardigingsproses teenoor konvensionele vervaardiging. Dit bied baie voordele, soos bv. massa-aanpassing, minder materiaal vermorsing ensovoorts. Die toevoegingsvervaardiging van gesertifiseerde implantate beskik egter nie oor dieselfde mate van dokumentasie en standaardisering as die konvensionele proses nie. Die volgende probleemstelling is hier aangespreek: “Deur die aanbied van toevoegingsvervaardiging as 'n implantaat vervaardigingsoplossing, moet die volledige proses (ontwerp, vervaardiging en na-vervaardigingsverwerking) ondersoek word om 'n gesertifiseerde vervaardigingsoplossing te ontwikkel”.
