3D Printer for Advanced Materials and Structures Research

该提案要求NSERC RTI计划为Cosine Additive的AM 1 + 3D打印机提供资金。这款3D打印机与长丝和颗粒挤出系统兼容，是大幅面、伺服控制和开放式架构。这些功能是支持从基础材料开发到应用加工和结构优化的广泛研究项目的关键。AM 1 + 3D打印机与具有长丝和颗粒原料的开放市场材料兼容。可以打印的材料范围从环保聚合物（例如聚乳酸、PLA）到聚醚醚酮（PEEK）或尼龙等技术聚合物。加热工作台与加热腔室相结合，增强了打印部件的尺寸控制。大打印尺寸（1100 mm x 850 mm x 850 mm）将能够打印各种几何形状甚至结构部件。所要求的打印机将支持工程学院和农业与环境科学学院的研究人员。通过所要求的3D打印机，将开发新的制造技术，将设计用于回收复合材料的增材制造的新材料，我们将创造受自然启发的先进轻质材料，将研究未来的增材制造优化协议，并将设计通过有限元优化构思的新型手术器械。所要求的3D打印机将影响大量的本科生，研究生和博士后研究员。在支持的研究项目中，估计每年有40-50名高级高素质人员将使用3D打印机进行研究。

This proposal requests funding from NSERC RTI program for the AM1+ 3D printer from Cosine Additive. This 3D printer is compatible with both filament and pellet extrusion systems and is large format, servo controlled and open architecture. These features are key to support a wide range of research projects from fundamental materials development to applied processing and structural optimization for a large range of applications. The AM1+ 3D printer is compatible with open market materials with both filament and pellet feedstock. The materials that can be printed range from environment-friendly polymers (e.g. polylactic acid, PLA) to technical polymers like polyether ether ketone (PEEK) or nylons. A heated table combined with a heated chamber enhance dimensional control of the printed parts. The large print size (1100 mm x 850 mm x 850 mm) will enable to print a wide range of geometries and even structural components. The requested printer will support researchers from the Faculties of Engineering and Agricultural and Environmental Sciences. With the requested 3D printer, novel manufacturing techniques will be developed, new materials for additive manufacturing from recycled composites will be engineered, advanced light-weight materials inspired by nature will we create, future additive manufacturing optimization protocols will be investigated, and novel surgical devices conceived via finite element optimization will be designed. The requested 3D printer will impact a large number of undergraduate, graduate students and postdoctoral fellows. Between the research programs supported, it is estimated that 40-50 per year senior highly qualified personnel will use the 3D printer for their research.
