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. Sautech Industries Inc. has developed a variant of binder jetting that allows for the ultra 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 costly, non-renewable, and can have detrimental effects on the environment and final product quality following burn-off. In collaboration with Kinova Robotics and Polytechnique Montreal, Sautech wishes to develop and test new binder formulations. Through this collaborative R&D project, new binder formulations will be screened and implemented in Sautech's printing systems - screening will be based on studies of binder-particle adhesion, penetration within a powder bed and resulting thermomechanical properties. The completion of this project will help situate Quebec and Canada as leaders in advanced additive manufacturing, allowing Sautech and Kinova 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。它通过将粘合剂配方打印到金属粉末上，从而使该层凝固并添加后续层。形成3D部分后，将其放置在高温烤箱中，以燃烧粘合剂并烧结金属颗粒。 Sautech Industries Inc.开发了一种粘合剂喷射的变体，可实现3D金属结构的超快速制造（比竞争对手快的500倍），但面临与使用的粘合剂有关的问题。具体而言，粘合剂是昂贵的，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。 Sautech与Kinova Robotics和Polytechnique Montreal合作，希望开发和测试新的粘合剂配方。通过此协作研发项目，将在Sautech的印刷系统中筛选和实现新的粘合剂配方 - 筛选将基于对粘合剂粒子粘附，粉末床的渗透以及产生的热力学特性的研究。该项目的完成将有助于将魁北克和加拿大作为高级添加剂制造业的领导者，从而使Sautech和Kinova能够在这个不断发展的领域进行创新并保持竞争力。**************************************
