Summary

通过非侵入性和实时技术,在3D打印过程中对聚合物长丝内的纳米级聚合物运动进行成像。微调此运动对于生产具有最佳性能和外观的结构至关重要。这种方法达到了塑料层熔合的核心,从而提供了对最佳印刷条件和材料设计标准的见解。

Transcript

我们的研究旨在改善3D打印过程中的层粘合。我们使用一种称为激光散斑成像的方法来实时可视化粘合过程。这些见解将指导打印条件的优化,有望增强材料设计和性能。

目前,使用红外成像技术研究层粘合,该技术可可视化该塑料*表面温度。为了用红外成像研究层粘合,假设内部温度和表面温度相等。此外,还必须知道温度与塑性流动性之间的复杂关系。

我们已经将激光散斑成像应用于3D打印,并展示了如何轻松获得对层粘合的更深入理解。我们的LSI方法测量塑料内部的聚合物运动,可视化层粘合,无需任何假设。该技术也是非侵入性的,易于使用,并且具有出色的灵敏度。

本研究中显示的方法可用于研究具有挑战性的3D打印或图案。结果可用于了解如何更改设置以提高打印质量。
