Binder jetting is an advanced additive manufacturing technique capable of 3D printing metallic structures. It**works by printing a binder formulation onto a bed of metal powder, allowing that layer to solidify and adding a**subsequent layer. Once the 3D part is formed, it is placed in a high-temperature oven to burn off the binder and**sinter the metal particles. Les Industries Sautech Inc. has developed a variant of binder jetting that allows for**the very rapid fabrication of 3D metallic structures (500 times faster than its competitors), but it is faced with**issues pertaining to the binders used. Specifically, the binders are non-renewable, and can have detrimental**effects on the environment and final product quality following burn-off. In collaboration with Polytechnique**Montreal, Sautech wishes to test new, bio-sourced binder formulations, namely chitosan and cellulose acetate.**Through this short-term Engage project, binder penetration into the powder beds will be assessed, along with**its drying properties, resulting tensile strength and thermal degradation properties (leading to a complete**sintering protocol). The completion of this project will help situate Canada as a leader in advanced additive**manufacturing, allowing Sautech to innovate and stay competitive in this evolving field.

粘合剂喷射是一种能够使用3D打印金属结构的高级添加剂制造技术。它可以通过将粘合剂配方印在金属粉末上，从而使该层凝固并添加**随后的一层。形成3D部分后，将其放在高温烤箱中以燃烧粘合剂，并**金属颗粒烧结。 Les Industries Sautech Inc.已开发了一种粘合剂喷射的变体，该变体可以迅速制造3D金属结构（比其竞争对手快的500倍），但面临与使用的粘合剂有关的**问题。具体而言，粘合剂是不可再生的，并且在燃烧后可能会对环境和最终产品质量产生不利影响。索特（Sautech）与理工**蒙特利尔（Montreal）合作，希望测试新的生物产生的粘合剂配方，即壳聚糖和乙酸纤维素。该项目的完成将有助于加拿大作为高级加性**制造业领导者的领导者，从而使Sautech在这个不断发展的领域中创新并保持竞争力。
