3D Hydrogel Printing

Hydrogels are soft, water-based gels with widespread applications in personal care products, medicine and biomedical engineering. Many applications require structuring the hydrogel into complex three-dimensional (3D) shapes. For these applications, light-based 3D printing methods offer exquisite control over material structure. All kinds of biological applications within hydrogel require to have open channels to feed the implanted cells and remove the waste. However, having these openings are challenging due to nature of SLA 3D Printing. Here is a video, showing successfully achieved open spiral channels within 600 um resolution.
