Development of material release mechanism for stereolithography-based 3D printing systems

3D Currax Solutions Inc.是一家位于不列颠哥伦比亚省基洛纳的公司。他们正在开发一种大规模生产的3D 使用最有前景的立体平版印刷(SLA)技术的具有大打印面积的打印机 由于它的快速制造能力、印刷精度和表面质量，它在技术上具有很大的优势。3D打印机下的 3D Currax Solutions的开发将紫外光从底部投射到构建板上，以便树脂 在树脂容器底部和成型板之间聚合。要打印下一层，即内部版本 将盘子向上移动，以带来另一层树脂。问题是聚合层之间的粘附性 树脂和树脂容器的底部，以及当模板向上移动时如何容易地分离它们 打印下一层。过大的脱模力会导致设计纸样的断裂和增加 打印对象的大小。在这项拟议的研究中，金博士的团队将利用他们在 3D打印、聚合物表面改性、传感器和致动器，以及先进的控制技术 与3D Currax Solutions的工程师一起解决大规模树脂的对象释放问题 SLA打印。

3D Currax Solutions Inc. is a company located in Kelowna, BC. They are developing a mass-production 3D printer with a large printing area using a stereolithography (SLA) technique which is the most promising techniques due to its rapid fabrication ability, printing accuracy, and surface quality. The 3D printer under development at 3D Currax Solutions projects the UV light from the bottom onto the build plate so that the resin between the bottom of the resin container and the build plate is polymerized. To print the next layer, the build plate is moved up to bring another layer of resin. The problem is the adhesion between the layer of polymerized resin and the bottom of the resin container and how to separate them easily when the build plate is moved up to print the next layer. The excessive release force results in the fracture of the designed pattern and an increase in the size of the printed object. In this proposed research, Dr. Kim's group will employ their strong background in 3D printing, surface modification of polymers, sensors and actuators, and advanced control techniques - along with the engineers from 3D Currax Solutions - to solve the object release problem of the resins in large-scale SLA printing.
