ENGLISH ABSTRACT: Selective Laser Melting (SLM) is a powder-based additive manufacturing process that has gained substantial interest in recent years due to its feasibility of producing geometrically- complex metallic components for end-use in various industries, with or without post-treatment procedures. This paper presents recent research undertaken on different scanning strategies and process parameters with the purpose of providing an overview of the achievable material performance of Ti6Al4V components, and comparing its properties with the conventionally-produced parts. In order to understand their output, differences in the building strategies of the systems studied are analysed, and their influence on the resulting mechanical and metallurgical properties is highlighted.

AFRIKAANSE OPSOMMING: Selektiewe lasersmelting is ʼn poeiergebaseerde toevoegingsver-vaardigingsproses wat onlangs wesenlike belangstelling gewek het as gevolg van die vermoë om geometries ingewikkelde metaal komponente te produseer sonder dat daar agteraf verdere behan-delinge toegepas moet word. Navorsing oor verskillende skandeerstrategieë en proses parameters en hul invloed op die bereikbare materiaaleienskappe van Ti6Al4V komponente word voorgehou. Die materiaaleienskappe word vergelyk met dié van komponente wat met konvensionele tegnieke vervaardig is. Om die uitset beter te verstaan, word verskille in die bou-strategieë van die stelsels bestudeer en analiseer, om sodoende hul invloed op die gevolglike meganiese- en metallurgiese eienskappe te bepaal.
