4D-Printed Aquatic Plants Spring to Life in “Hydrophytes” by Nicole Hone
wait what do you mean “4D printed”
4d printing is not a thing we cannot access dimensions higher than the third
The 4th dimension is time. Here, an object is printed in 3 dimensions but is constructed so that the stresses and strains in the material that occur when interacting with some environment it is in (such as water), will cause it to move in a predicted way. So it is 4D printed. This isn’t the only research group studying this. It is what it has been called for a few years now.
