dc.description.abstractENGLISH ABSTRACT: Selective laser melting scanning strategies influence the quality characteristics of parts, such as form accuracy and residual stresses. Previous research on the effect of laser scanning strategy parameters (such as scan vector length) demonstrates that residual stresses decrease with scan vector length reduction. However, most of these studies overlook the associated porosity and how this can contribute to stress relief. In this work, three scan vector lengths were compared to evaluate their impact on residual stresses, achievable part density, and scanning time. Reducing the scan vector length generally lowers residual stresses magnitudes, but introduces porosity as a result of localised overheating.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Selektiewe lasersmelt skanderingstrategieë beïnvloed die gehalte eienskappe van onderdele, soos vorm akkuraatheid en res-spannings. Vorige navorsing oor die invloed van laserskandeerstrategie parameters (soos vektorlengte) demonstreer dat res-spannings verminder met ʼn toename in skandeervektor lengte. Die meeste van hierdie studies neem egter nie die gepaardgaande poreusheid (en hoe dit kan bydra tot spanningverligting) in ag nie. In hierdie studie word drie skandeervektor lengtes vergelyk om die invloed daarvan op resspannings, bereikbare onderdeeldigtheid en skandeertyd te evalueer. Deur die skandeervektor lengte te verkort het oor die algemeen gelei tot verlaagde res-spannings, maar veroorsaak poreusheid as gevolg van lokale oorverhitting.af_ZA
