SUMMARY: Engineers have used a modified 3-D printer and frozen water to create three-dimensional objects made of graphene oxide. The structures could be an important step toward making graphene commercially viable in electronics, medical diagnostic devices and other industries.

"Graphene is notoriously difficult to manipulate, but the structures we built show that it's possible to control its shape in three-dimensional forms," said Chi Zhou, assistant professor of industrial and systems engineering at UB's School of Engineering and Applied Sciences, and a corresponding author of the study.
Zhou is a member of the Sustainable Manufacturing and Advanced Robotic Technologies (SMART), a UB Community of Excellence launched in 2015; he also is a member of UB's New York State Center of Excellence in Materials Informatics.

After the process is completed, the lattice is dipped in liquid nitrogen, which helps form even stronger hydrogen bonds. The lattice is then placed in a freeze dryer, where the ice is changed into gas and removed. The end result is a complex, three-dimensional structure made of graphene aerogel that retains its shape at room temperature.

The researchers plan to build on their findings by investigating how to create aerogel structures formed of multiple materials.

Directly related to your post on graphene oxide in the jab - which I sent to numerous friends.

No, this one is not graphene but pyrolyzed phenol resorcinol.
Placing non-resorbable particles, including nanoparticles, into the body can be dangerous.
Example:
There is plenty of literature about drug addicts who crush up pills to inject. They can get lung and heart problems from the crospovidone particles used as disintegrants in tablets.
I can see this being made into thread to be woven like kevlar producing a stronger, lighter weight bullet resistant cloth. If set with epoxy or ceramic, could be very useful as hard armor.
