Nanogrande (NG) is a solution provider in the high-precision metal additive manufacturing (AM) field, combining AM, nanotechnology and machine learning. They provide unique freedom of design and material choice for high-precision parts by their developed 3D printer combining its Power Layering technology with laser sintering. However, most of the generated micro metal parts for NG's markets require post-processing steps. As additional process steps appear to be undesired, deploying post-processing could have an additional benefit of reducing the overall manufacturing time by balancing layer height and the polishing process to reduce the surface roughness of the generated metal micro-parts. Among other methods, electrochemical polishing (EP) seems the most suitable candidate for post-processing such parts. Nevertheless, EP is still unexplored in combination with this novel high-precision 3D printing method and NG is lacking the required expertise on such post-processes.The proposed project aims to find a trade-off between layer thickness, printing speed and polishing. An optimum should be achieved to get smooth and flat surfaces to maintain high quality parts at reasonable fabrication time. Secondary, the project aims to acquire more knowledge of the printing technology and its interaction with post-processes. To solidify their unique market position it is key for NG to improve their 3D printing process-flow and to increase their expertise. The proposed project aims to support this mission by exploring post-processing integration in NG's printing process and study the deposition process. Since NG is based in Montréal, expanding and improving their patented 3D printing technology will secure their leading market position in the customized metal product manufacturing field and could lead to the creation of new jobs thereby providing a benefit to Canada overall.

Nanogrande (NG) 是高精度金属增材制造 (AM) 领域的解决方案提供商，将增材制造、纳米技术和机器学习相结合，通过其开发的 3D 打印机结合其技术，为高精度零件提供独特的设计和材料选择自由度。然而，NG 市场生产的大多数微型金属零件都需要后处理步骤，因为额外的工艺步骤似乎是不需要的，因此部署后处理可能具有减少成本的额外好处。通过平衡层高度和抛光工艺来降低生成的金属微型零件的表面粗糙度，从而缩短总体制造时间。在其他方法中，电化学抛光 (EP) 似乎是此类零件后处理的最合适选择。这种新颖的高精度 3D 打印方法尚未得到探索，NG 缺乏此类后处理所需的专业知识。拟议项目旨在找到层厚度、打印速度和抛光之间的平衡点。变得顺利并且其次，该项目旨在获得更多关于打印技术及其与后处理的相互作用的知识，这是 NG 改进其 3D 打印工艺的关键。拟议的项目旨在通过探索 NG 打印过程中的后处理集成并研究沉积过程来支持这一使命，因为 NG 总部位于蒙特利尔，扩展和改进其专利 3D 打印技术将确保其安全。主导市场在定制金属产品制造领域的地位，可能会创造新的就业机会，从而为加拿大整体带来好处。
