This project seeks support for the acquisition of a Selective Laser Sintering (SLS) Technology based three-dimensional (3D) Printer, which is a demanding technology and fundamental research tool for new eco-friendly polymers and biobased materials research at the University of Guelph. The main goal of the proposed equipment is to print complex shaped bioplastic products from sustainable biomass materials and to understand the fundamental properties and performance of the printed products in order to check their viability in various applications such as biomedical, electronics, packaging and automotive, which can open up new doors to create novel materials. This powder-based additive manufacturing is a one step processing technique used to manufacture complex shaped products without compromising the analytical properties such as molecular weight and thermal degradation of the materials, which is not at all possible in two step processing techniques like filament-based 3D printing or other conventional injection moulding. In the requested powder-based 3D printer, the polymer powder is heated below its melting point and the laser will help to draw the shape of the desired products. In such case, the remaining powder can be reused further to produce more specimens without altering the properties. The equipment will provide opportunities for over 30 graduate students, undergraduate students, and post-doctoral researchers working in the area of biopolymers and biomaterials. However, the broader synergistic impact of this instrument will be realized by its use for interdisciplinary research, HQP (highly qualified personnel) training, training of summer interns, and encouragement of new users. For the Canadian economy to be competitive globally, the opportunities in new eco-friendly materials need to be explored that can reduce reliance on petro-chemicals and would provide a strong foundation in renewable resource-based materials for creating a greener manufacturing sector. This project is uniquely targeted to understand the properties and performance of the printed sustainable biopolymers and biocomposites. Overall, the proposed 3D printer will tremendously aid researchers in finding solutions through new discoveries and innovations in biomaterials for societal uses.

该项目寻求支持购买基于选择性激光烧结（SLS）技术的三维（3D）打印机，这是圭尔夫大学新型环保聚合物和生物基材料研究的一项要求很高的技术和基础研究工具。拟议设备的主要目标是用可持续生物质材料打印复杂形状的生物塑料产品，并了解打印产品的基本特性和性能，以检查其在生物医学、电子、包装和汽车等各种应用中的可行性。可以打开创造新材料的新大门。这种基于粉末的增材制造是一种一步加工技术，用于制造复杂形状的产品，而不会影响材料的分子量和热降解等分析特性，而这在基于长丝的 3D 等两步加工技术中根本不可能实现印刷或其他传统的注塑成型。在所需的粉末 3D 打印机中，聚合物粉末被加热到其熔点以下，激光将有助于绘制所需产品的形状。在这种情况下，剩余的粉末可以进一步重复使用以生产更多的样本，而不会改变特性。该设备将为30多名在生物聚合物和生物材料领域工作的研究生、本科生和博士后研究人员提供机会。然而，该工具更广泛的协同影响将通过跨学科研究、HQP（高素质人才）培训、暑期实习生培训和新用户鼓励来实现。为了使加拿大经济在全球具有竞争力，需要探索新型环保材料的机会，以减少对石化产品的依赖，并为可再生资源材料的创建奠定坚实的基础，从而创建更绿色的制造业。该项目的独特目标是了解打印的可持续生物聚合物和生物复合材料的特性和性能。总体而言，拟议的 3D 打印机将极大地帮助研究人员通过社会用途生物材料的新发现和创新来寻找解决方案。
