Surface Treatments of Advanced Parts Made by Additive Manufacturing

增材制造已经颠覆了现代制造业;这个蓬勃发展的行业使工程师能够以以前无法想象的方式设计功能组件。利用AM逐层加工的零件可以包含内部通道和复杂的几何形状。然而，在某些情况下，后处理，以实现特定的表面光洁度和尺寸精度是关键，在提供增材制造零件的规格。当零件具有复杂设计的通道时，这是不可能的，没有视线。FZ Engineering是一家魁北克初创公司，他们利用了这一特定的工业需求;他们拥有6项针对AM生产部件的专利后处理技术，将打印部件转化为应用就绪，尺寸完美的表面处理部件。下一代AM部件将是微结构控制的。这种转变，从多晶纹理，使组件增强的机械和腐蚀性能，使组件的生产越来越苛刻的应用。当采用FZ Engineering的专利工艺进行处理时，溶解行为的这种变化将导致表面发生不可预测的变化，从而导致材料去除。因此，本提案的目的是用3种不同的合金生产这种微结构控制的部件，并将其整合到FZ Engineering的表面精加工工艺中。具体而言，材料去除率和表面变化将被表征，并集成到FZ的预测模型中;以获得这些专业零件的常规加工的稳健迭代。AM的设计自由度与具有新微结构的部件相结合，有可能进一步破坏这个行业，这项工作的交付将使FZ能够进一步发展他们在这个不断增长的行业中的竞争优势。

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.
