Engineered living materials: Scientists 3D print with bio-ink made from tobacco cells
They 3D printed this bio-ink on a flat plate or inside a container filled with another gel to form snowflakes, leaves, and spirals. The hydrogel in the print materials was then “cured with blue ...

An alloy adjustment: Controlling metal microstructures results in better 3D printing
Just as a snowflake's intricate structure vanishes when it melts and transforms when it refreezes, the microstructure of metals can change during the 3D printing process, resulting in strengths or ...
