About the webinar
4D printing is gaining great attention as a next-generation manufacturing technology that aims to produce dynamic 3D structures capable of changing shape or behavior autonomously in a manner resembling natural movement.
The primary research focus of the rapidly evolving 4D printing technology is the development of novel hydrogel materials that enable shape control or motion-related features in conjunction with high resolution 3D printing. In this webinar, a couple of strategies in 3D hydrogel ink formulation will be introduced to improve the response of 3D architecture without sacrificing printing resolution.
- Adding sugar to hydrogels to provide hydrogel architectures containing macropores to overcome slow actuation kinetics.
- Accommodating a photothermal converter capable of converting light of a specific wavelength into heat inside the hydrogel.
- Formulating gold nanorods-hydrogel nanocomposite as an effective photothermal converter in 3D printable hydrogel inks.
