Design and Process Modeling for Manufacturing Custom Product

加法制造(AM)，又名3D打印以惊人的速度发展，并在汽车、航空航天、医疗、电子、商业和时尚行业等许多重要应用中产生越来越大的影响。这种有希望的方法将改变产品设计和制造中制造的性质。AM最吸引人的能力是，它可以在不增加太多时间、材料或成本的情况下生产定制产品，这使得“复杂性免费”。与大规模生产的同类产品相比，定制产品提供了固有的优势。它们可以提供更多的舒适性、独特的美感或更好的性能。该研究项目的最终目标是增强当前关于将传统大规模生产演变为大规模定制所必需的设计和制造技术的基础知识。*为了利用AM的能力，拟议的研究将超越我们目前对传统计算机辅助设计(CAD)系统的理解，转向由AM支持的用于定制产品设计的新设计空间。将开发新的表示法和设计规则，以将AM工艺的特点联系起来。将研究用于四维(4D)打印(第四维是时间)的设计和工艺建模方面的先进技术，以创造出类似贝壳的、轻便的、可以自我成形、自折叠或自组装的智能结构。将开发复杂的模拟来可视化和预测制造过程。还将开发现场过程监控和闭环反馈系统，以提高制造的重复性和产品一致性。*这项研究将加强加拿大在先进制造领域的全球领先地位的竞争力，并在各个应用领域与工业研究伙伴建立重要合作，为经济提供高科技工作机会，并激励下一代加拿大人追求科学和工程。将培训不同层次(博士、硕士和本科生)的高素质人才(HQP)。他们将在加拿大的许多高科技领域获得高要求的技能和专业知识。这些HQP将在一个激励、动态和协作的环境中工作，研究和回答最先进的研究问题。

Additive manufacturing (AM), a.k.a. 3D printing, has been developed at exceptional rates and has a growing impact in many important applications such as automotive, aerospace, medical, electronics, commercial, and fashion industries. This promising approach will change the nature of manufacturing in product design and fabrication. The most attractive capability of AM is that it can produce custom products without much increasing in time, material, or cost, which makes “complexity for free”. Custom product offers inherent advantages over their mass produced counterparts. They can provide more comfort, unique aesthetic appeal, or better performance. The ultimate goal of this research program is to enhance the current fundamental knowledge regarding on the necessary design and manufacturing techniques to evolve the traditional mass production to mass customization.***To utilize the capability of AM, the proposed research will go beyond our current understanding of the traditional Computer-Aided Design (CAD) system towards the new design spaces enabled by AM for custom product design. New representations and design rules will be developed to link the characteristics of AM processes. Advanced technologies in design and process modeling for four-dimensional (4D) printing (the fourth dimension is time) will be investigated to create smart structures that are shell-like, lightweight, and can be self-shaping, self-folding, or self-assembly. Sophisticated simulations will be developed to visualize and predict the manufacturing process. In-situ process monitoring and close-loop feedback system will also be developed to improve the manufacturing repeatability and product consistency.***This research will strengthen the competitiveness of Canada's global leadership in advanced manufacturing and build up important collaboration with industrial research partners in various fields of applications, which provides the economy with a supply of high-tech jobs and inspires the next generation of Canadians to purse science and engineering. Highly qualified personnel (HQP) at different levels (PhDs, Masters, and Undergraduate students) will be trained. They will gain highly demanded skills and expertise in many high technology sectors in Canada. These HQPs will work in a stimulating, dynamic, and collaborative environment to research and answer the state-of-the-art research questions.
