Scientists have 3D printed a smart gel that could lead to the development of \"living\" structures in human organs and tissues, soft robots and targeted drug delivery.
This method includes printing 3D objects with gel (water-containing gel)
When the temperature changes, the change will change over time, says Howe Lee, an assistant professor at Rutgers University in the United States.
The study, published in the journal Science report, shows that fast, scalable, high
The resolution of the gel is 3D printed and, despite containing water, remains solid and maintains its shape.

The resolution of the gel is 3D printed and, despite containing water, remains solid and maintains its shape.
In our lives, including contact lenses, diapers and human bodies, there are gels everywhere.
Smart gels can provide structural rigidity in organs such as lungs, and can contain small molecules such as water or drugs that can be transported and released in vivo.
Lee said it can also create a new field of soft robots and implement new applications in terms of flexible sensors and actuators, biomedical devices, and platforms or brackets for cell growth.
\"The full potential of this smart gel has not been released so far,\" Lee said . \".
\"We added another dimension to it, and this is the first time someone has done so.
They\'re flexible, shaped-
Deformed material.
I like to call them smart materials . \"
Engineers work with a gel that has been used for decades in a device that produces motion and biomedical applications, such as a scaffold for cell growth.
However, gel manufacturing relies heavily on traditional double
Size methods such as molding and printing.
The researchers used
Based on fast, inexpensive technology, various materials can be printed into 3D shapes.
It includes printing special resin layers for building 3D objects.
The resin consists of a gel, a chemical used as an adhesive, another chemical that is conducive to bonding under light irradiation, and a dye that controls the penetration of light.
