In the field of additive manufacturing DLP vat technologies are promising 3D printing techniques. The need of highly efficient photoiniating systems drives us to the development of photocyclic 3-component initiators. In order to improve the 3D printing sensitivity, we present in this paper the use of synthesized clay to tune up the photochemistry underlying the initiating radical production. Therefore, a three-component initiating system, based on a cationic dye, two coinitiators and with a clay filler suitable for DLP 3D printing of acrylate resins leading to high quality of parts and low printing time, is developed.
在增材制造领域,数字光处理(DLP)光固化技术是很有前景的3D打印技术。对高效光引发体系的需求促使我们开发光循环三元引发剂。为了提高3D打印灵敏度,我们在本文中展示了使用合成粘土来调节引发自由基产生背后的光化学过程。因此,开发了一种基于阳离子染料、两种共引发剂并带有适合丙烯酸酯树脂DLP 3D打印的粘土填料的三元引发体系,该体系能实现高质量部件和较短的打印时间。
