The inspiring abundance of novel manufacturing technologies has created new opportunities to solve old problems and address areas of unmet need. An area of particular interest is developing low-cost rapid prototyping platforms for glass to test efficiency and feasibility of numbering-up systems. Scaling-up is the approach that industry applies today for sizing-up devices developed in the lab. This approach is problematic in some fields such as for the chemical industry since the physical phenomena governing the device operation might change and become unstable at a larger scale (like for micro-batteries). To maintain the device functionality, numbering-up strategy is promising especially for small-scale devices. This strategy implies connecting identical devices of the same size to create a system with increased throughput. My research program aims to develop innovative rapid prototyping techniques for glass that are low-cost, flexible and precise. Such techniques will be able to machine glass and build multi-material structures on the machined surface, hence tailoring the surface properties to fit the need of the application. Furthermore, incorporating a different type of material into the glass surface would lead to creating surface glass-matrix composites which are important for chemical, optoelectronics and semiconductor applications. In the short-term, I aim to translate an electrochemical machining process called Spark Assisted Chemical Engraving to a rapid prototyping technique through: 1) Developing methods for adjusting in a controlled way the surface properties of machined structures by micro-particles incorporation 2) Developing algorithms that allow accelerated precision cutting and machining of high-aspect ratio structures under reduced axial and lateral machining forces 3) Developing methods for controlling the surface topography including the texture and roughness Canada's manufacturing sector represents more than 10 percent of the country's total GDP and manufacturers export more than $354 billion each year which is 68 per cent of all of Canada's merchandise exports. The proposed research directly contributes to developing novel precision manufacturing techniques for glass and glass-matrix composites. It will therefore help in advancing the knowledge in the precision manufacturing field. The generated knowledge will be transferred to the research community and practitioners. It will be applied in different industries to create for example light pipes, lab-on-a-chip devices, and magneto-optical switches. The research will train highly qualified manufacturing professionals (students) and equip them with the knowledge and the skill set required for future manufacturing engineers. This will spur growth and competitiveness in the Canadian manufacturing industry.

新制造技术的丰富性为解决老问题和满足未满足的需求创造了新的机会。一个特别感兴趣的领域是开发低成本的玻璃快速原型平台，以测试编号系统的效率和可行性。按比例放大是当今工业界应用于在实验室中开发的设备尺寸放大的方法。这种方法在某些领域中是有问题的，例如对于化学工业，因为控制设备操作的物理现象可能会改变，并且在更大的范围内变得不稳定（例如对于微电池）。为了保持设备的功能，特别是对于小型设备，编号策略是有前途的。这种策略意味着连接相同大小的相同设备，以创建具有更高吞吐量的系统。 我的研究项目旨在开发创新的玻璃快速成型技术，这些技术成本低，灵活且精确。这些技术将能够加工玻璃并在加工表面上构建多材料结构，从而定制表面特性以满足应用需求。此外，将不同类型的材料结合到玻璃表面中将导致产生表面玻璃基质复合材料，这对于化学、光电子和半导体应用是重要的。在短期内，我的目标是通过以下方式将一种称为火花辅助化学雕刻的电化学加工工艺转化为快速原型技术：1）开发通过微粒掺入以受控方式调节加工结构的表面性质的方法2）开发允许在减小的轴向和横向加工力下加速高纵横比结构的精密切割和加工的算法3）加拿大的制造业部门占该国国内生产总值的10%以上，制造商每年的出口额超过3540亿加元，占加拿大所有商品出口额的68%。该研究将直接有助于开发玻璃和玻璃基复合材料的新型精密制造技术。因此，它将有助于推进精密制造领域的知识。所产生的知识将转让给研究界和从业人员。它将应用于不同的行业，例如光管，芯片实验室设备和磁光开关。该研究将培养高素质的制造专业人员（学生），并为他们提供未来制造工程师所需的知识和技能。这将刺激加拿大制造业的增长和竞争力。
