Abstract

Binder Jetting is a layer-by-layer 3D printing process that consists of selectively binding particles together on each layer to create 2D patterns of a part. A drying step is usually performed after printing to evaporate some of the binder solvents before the next layer is applied. However, optimization of binder drying for improved part manufacturing has received little attention. In this paper, a dedicated test bench was used to measure binder mass loss over time under various drying conditions. By establishing a methodology and an experimentally validated drying model, this work represents a significant advance in the understanding of the drying phase and binder behavior between the deposition of successive layers. A time-dependent conceptualization of binder saturation within a layer of powder is presented for the first time, and valuable insights are provided to pave the way for improved selection of printing and drying parameters for aqueous binders in Binder Jetting.

了解粘结剂喷射干燥动力学：发展物理模型，以改进干燥参数的选择和更好地控制粘结剂饱和度

粘合剂喷射是一种逐层3D打印过程，包括在每层上选择性地将颗粒结合在一起，以创建零件的2D图案。干燥步骤通常在印刷后进行，以便在下一层应用之前蒸发一些粘合剂溶剂。然而，为改进零件制造而优化粘合剂干燥却很少受到关注。在本文中，使用了一个专用的试验台来测量粘合剂的质量损失随时间在各种干燥条件下。通过建立一种方法和实验验证的干燥模型，这项工作在理解干燥阶段和连续层沉积之间的粘合剂行为方面取得了重大进展。第一次提出了一层粉末内粘合剂饱和度的时间依赖性概念，并提供了有价值的见解，为粘合剂喷射中水性粘合剂的印刷和干燥参数的改进选择铺平了道路。
