针对可光固化水凝胶成形速度快、粘度低的特点，提出了一种包括电磁阀喷头系统和光源系统的喷墨式打印方法，能克服以成缸溶液直接扫描加工多种可光固化水凝胶存在的加工复杂、材料易被污染和损耗高等缺点。用光学显微镜对固化液滴和堆积直线进行了测量和分析，结果表明：随着喷头孔径和压力的增大，液滴固化直径增大；当浓度>30%时，随着浓度的增大，液滴固化直径减小。同时，建立了液滴固化和液滴堆积成形模型，形成的直线宽度不大于单个液滴的直径且宽度均匀。

Owing to the fast forming speed and low viscosity of the photo-curable hydrogel ,an inkjet printing method with electromagnetic valve sprinkler and lighting systems was proposed ,which can overcome the processing complexity ,the high loss and easy pollution of materials in printing various hydrogels by the direct scanning of the cylinder solution. Solidified droplets and the accumulation of line are measured by optical microscope ,the results show that as the nozzle aperture and pressure increases,the droplets solidify diameter increases. And when the concentration is greater than 30 % and increases,the droplet diameter decreases. By establishing the droplets solidify and droplet deposition modeling model,the width of forming a straight line is not greater than a single droplet′s diameter and reflects its uniformity.
