The price of a printed metal part is high today because the processes use powders with very narrow characteristics to ensure good performance. These powders are expensive, limiting their fields of application. Ensuring the same level of quality with powders having coarser characteristics will generate enormous gains, but such a change is difficult because the process is highly sensitive to powder characteristics; requiring a significant paradigm shift. Changing the type of powder imply a complex process of developing parameters and analysis. The project's industrial partner (AP&C) will be able to produce a wide variety of powder types in order to establish which characteristics are the most appropriate to increase printing performance, process reproducibility, quality of the parts produced and guarantee analysis. A significant cost/benefit is introduced by such a change. This project will define the necessary modifications to the printing process to be able to use powders with a larger size distribution than the standard without compromising the quality of the parts produced. Through close collaboration between an experienced Korean printer, a Quebec powder producer, and a Quebec characterization center, the project will establish the necessary changes to enable the manufacturing of aeronautical quality parts using new types and less expensive powders. The results will reduce costs, develop expertise in both powder development and advanced characterization and train qualified personnel in a field in demand.

如今，印刷金属零件的价格很高，因为该工艺使用具有非常狭窄的特征的粉末来确保良好的性能。这些粉末很昂贵，限制了它们的应用领域。确保具有较粗特性的粉末的质量相同水平会产生巨大的收益，但是这种变化很困难，因为该过程对粉末特征高度敏感。需要重大的范式转移。改变粉末类型意味着开发参数和分析的复杂过程。该项目的工业合作伙伴（AP＆C）将能够生产多种粉末类型，以确定哪些特征最适合提高印刷性能，过程可重复性，生产零件的质量和保证分析。这种变化引入了重大成本/收益。该项目将定义对打印过程的必要修改，以便能够使用比标准更大的粉末，而不会损害所产生的零件的质量。通过经验丰富的韩国打印机，魁北克粉末生产商和魁北克特征中心之间的密切合作，该项目将建立必要的更改，以便使用新型和便宜的粉末来制造航空质量零件。结果将降低成本，发展粉末开发和高级表征的专业知识，并在需要的领域中训练合格的人员。
