Design and Process Modeling for Manufacturing Custom Product

增材制造（AM），又名3D打印技术已经以惊人的速度发展，并在许多重要应用中产生越来越大的影响，如汽车，航空航天，医疗，电子，商业和时尚行业。这种有前途的方法将改变产品设计和制造中的制造性质。AM最吸引人的能力是它可以在不增加时间、材料或成本的情况下生产定制产品，这使得“复杂性免费”。定制产品比大规模生产的产品具有固有的优势。它们可以提供更舒适、独特的美学吸引力或更好的性能。该研究计划的最终目标是提高当前关于必要的设计和制造技术的基础知识，以使传统的大规模生产向大规模定制发展。为了利用AM的能力，拟议的研究将超越我们目前对传统的计算机辅助设计（CAD）系统的理解，走向新的设计空间，使AM定制产品设计。新的表示和设计规则将被开发，以链接增材制造过程的特点。将研究四维（4D）打印（第四维是时间）的设计和过程建模的先进技术，以创建壳状，轻质，可以自成形，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，以提高制造重复性和产品一致性。*这项研究将加强加拿大在先进制造业的全球领导地位的竞争力，并与各个应用领域的工业研究合作伙伴建立重要的合作关系，为经济提供高科技就业机会，并激励下一代加拿大人追求科学和工程。将培训不同层次的高素质人员（HQP）（博士，硕士和本科生）。他们将获得加拿大许多高科技领域的高要求技能和专业知识。这些HQP将在一个激励，动态和协作的环境中工作，以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.
