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.********

粘合剂喷射是一种先进的增材制造技术，能够3D打印金属结构。它的工作原理是将粘合剂配方印刷到金属粉末床上，使该层固化并添加后续层。一旦形成3D部件，将其放置在高温烘箱中以烧掉粘合剂并烧结金属颗粒。Sautech Industries Inc.该公司开发了一种粘合剂喷射变体，可以超快速制造3D金属结构（比竞争对手快500倍），但它面临着与所使用的粘合剂有关的问题。具体地，粘合剂是昂贵的、不可再生的，并且在烧除之后可能对环境和最终产品质量具有不利影响。通过与Kinova Robotics和Polytechnique Montreal的合作，Sautech希望开发和测试新的粘合剂配方。通过这一合作研发项目，新的粘合剂配方将被筛选并应用于Sautech的印刷系统中-筛选将基于对粘合剂颗粒粘附力、粉末床内渗透力以及由此产生的热机械性能的研究。该项目的完成将有助于魁北克魁北克和加拿大成为先进增材制造的领导者，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。
