Advanced additive manufacturing with high-performance green binders******

粘结剂喷射是一种先进的添加剂制造技术，可用于3D打印金属结构。它的工作原理是将粘结剂配方打印到一层金属粉末上，使这一层固化并添加后续的一层。一旦形成3D零件，将其放入高温烤箱中烧掉粘结剂并烧结金属颗粒。Sautech Industries Inc.已经开发出一种粘结剂喷射的变体，可以超快制造3D金属结构(比其竞争对手快500倍)，但它面临着与所使用的粘结剂有关的问题。具体地说，粘结剂是昂贵的、不可再生的，并且在烧毁后可能会对环境和最终产品质量产生有害影响。通过与Kinova Robotics和蒙特利尔理工学院的合作，Sautech希望开发和测试新的粘结剂配方。通过这一合作研发项目，新的粘结剂配方将在Sautech的印刷系统中进行筛选和实施-筛选将基于粘结剂-颗粒粘附性、在粉床中的渗透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和加拿大成为先进添加剂制造领域的领导者，使Sautech和Kinova能够在这一不断发展的领域创新并保持竞争力。

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.********
