Published by the journal Science, a new class of 3D printing materials developed by scientists at the University of Georgia, University of Wisconsin, the University of Michigan, and the Technical University of Berlin uses multi-lithium ion-weavings instead of that aforementioned staple material known as filament.

It’s the first time a material that can form almost completely in its own double layer of material has been made. This is thanks to tiny nano and micro dendrites — porous material that can be built using electrolytic and regolith processes that can remove anything short of solid copper or tin.
Microdendrites take their name from the most common cell found in living organisms — our own. They help support the growth of cells and thus provide the building block for embryos, an ultra-fast way to print biological material, and we wouldn’t be able to get by without them. The fluid becomes ion-weaving paper, which is then connected with other large-scale, stable, airless materials, such as polyvinyl chloride and a variety of gases that are very strong in the thin air that surrounds us.
The graphene-orbital hydrogel filament, which consists of hydrodent fluids and goes by the brand name graphene porphyrin, had previously been an object in research settings. The scientists have decided to use the hydrogel for something far more basic and easy to manufacture. “With this design we can print objects as large as our bones but not as hard as our skulls,” says Eric Manning, the lead author on the study.
The nano-tidiation of graphene reveals the unique properties of small hydrogels. These are delicate and soft—for comparison, you don’t buy quality jeans that are made from French-ness. It took the researchers only six months to separate from graphene hydrogel and put them into the tube that measures 300 microns long.
Because the hydrogel is made from magnesium polyide and no fluorine, it’s solid enough to store copious amounts of energy. That allows the hydrogel’s fast-absorbing surfaces to give the fabric a textured effect, particularly when aligned with other 3D-printed materials.
The purpose of all this is to more easily print higher-quality objects, like prosthetic limbs. “It’s incredibly easy to find good materials at low price points,” says Manning. “But to print these great, interesting materials that can be used with anything, it’s really beneficial to use 3D printing materials to print materials that can build an entire human body.”
