Innovation in Canadian companies with additive manufacturing

附加制造的兴趣在于这样一种想法，即可以通过使用3D模型直接获得部件并将其制造成接近净形状，而不是具有多个制造步骤，这可能不利于部件的快速生产。在使用的材料有价值并且使用AM变得更有利可图的情况下，以及当可以使用新的部件设计来在保持相同性能的情况下减轻部件重量或者为部件提供传统加工无法获得的特性时，添加制造技术具有取代传统制造技术的潜力。AM技术对于大量使用低成本材料制造的部件来说往往是不合理的，因为这些部件已经使用经过数十年优化的技术制造。此外，低成本的材料可以很容易地加工得到零件，因此，即使浪费了大量的材料也没有关系。为了在添加剂制造工艺(AM)方面创造可持续的世界级专业知识，CMQ希望培训能够在从研究到实施的整个AM过程中提供完整服务的专家。CMQ将把某些工艺列为未来五年的优先事项：定向能量沉积AM(Lens，www.optomec.com)和超声波添加剂制造(UAM，www.Fabrisonic.com)。该中心希望在加拿大围绕这些技术发展一批知识和独特的专业知识。CMQ将支持利用其创新能力以及与大学和其他研究中心的关系的公司的愿望，如CRIQ(魁北克3D网络)、蒙特利尔高等理工学院、拉瓦尔和麦吉尔大学和设备供应商。具体地说，该中心将通过侧重于制造业中小企业在提高生产力和开发国际利基市场方面的投资需求来实现这一点。这个项目是应公司的要求而创建的，具有很高的科学性和技术性。魁北克冶金中心(CMQ)建议沿着两个不同的研究方向发展金属添加剂制造方面的专业知识：(1)发展超声波添加剂制造(UAM)和(2)发展激光工程网络成形(透镜)。

The interest of additive manufacturing resides with the idea that parts can be obtained directly from using a 3D model and fabricated to near net shape as opposed to have multiple steps of manufacturing which can be detrimental for a rapid production of parts. Additive manufacturing technologies have the potential of replacing traditional manufacturing techniques in cases where the material used has a value and it becomes more profitable to use AM and also when new designs of parts can be used to either lighten the part while maintaining the same properties or providing the part with properties that could not be obtained through traditional processing. AM technologies tend to not be justifiable for parts made in huge production number using low cost materials as those parts are already made using technologies which had multiple decades of optimization. Furthermore, low cost materials can be easily machine to obtain a part and as such, it does not matter that a significant amount of material is wasted. To create sustainable world-class expertise in additive manufacturing processes (AM), the CMQ wishes to train specialists who can provide a complete service over the whole AM process, from research to implementation. The CMQ will make certain processes a priority for the next five years: directed energy deposition AM (LENS, www.optomec.com) and ultrasonic additive manufacturing (UAM, www.fabrisonic.com). The Centre wants to develop a pool of knowledge and unique expertise in Canada precisely surrounding these technologies. The CMQ will support the aspirations of companies exploiting its capacity for innovation and its relationship with universities, other research centers, as CRIQ (Quebec 3D Network), École de technologie supérieure de Montreal, Laval and McGill universities and equipment suppliers. Specifically, the Centre will do so by focusing on the needs of manufacturing SMEs to invest in improving the productivity and development of international niche markets. This project, highly scientific and technological, was created at the request of companies. The Quebec Metallurgy Center (CMQ) proposes to develop the expertise in metallic additive manufacturing along two different axis of research: (1) Development of ultrasonic additive manufacturing (UAM) and (2) Development of Laser-engineered net shaped (LENS).
