Additive manufacturing has disrupted modern manufacturing; this booming industry is enabling engineers to design functional components in previously unimagined ways. Parts utilizing the layer-by-layer processing of AM can incorporate internal channels and complex geometries. However, in some circumstances, post processing, to achieve specific surface finishes and dimensional accuracy are key in delivering AM parts to specification. This can be impossible when parts have channels with complex designs, without line of sight. FZ Engineering are a Quebec Startup who have capitalized on this specific industrial need; they have 6 patented post-processing technologies for AM produced parts, transforming printed components to application ready, dimensionally perfect, surface treated components.The next generation of AM components will be microstructure-controlled. This shift, from polycryalline textures, gives components enhanced mechanical and corrosion performance allowing the production of components for more and more demanding applications. This change in dissolution behavior will result in unpredicted changes at the surface and consequent material removal when processed by FZ Engineering's Patented Processes. Therefore, the aim of this proposal is to produce such microstructure-controlled components from 3 different alloys, and integrate them into FZ Engineering's surface finishing process. Specifically, the rate of material removal, and surface changes will be characterized, and integrated into FZ's predictive model; to obtain a robust iteration of their conventional processing for these specialist parts. The merging of AM's design freedoms in tandem to parts with new microstructures, has the potential to further disrupt this industry the delivery of this work will enable FZ to further grow their competitive advantages in this ever growing industry.
