3D printing for regrowing bones.
As explained by Fellow at RMIT, Vice-Chancellor O´Connell,¨ The shapes you can make with a standard 3D printer are constrained by the size of the printing nozzle—the opening needs to be big enough to let material through and ultimately that influences how small you can print.
He also mentioned, the gaps in between the printed material can be way smaller, and far more intricate.
By flipping our thinking, we essentially draw the structure we want in the empty space inside our 3D-printed mold. This allows us to create the tiny, complex microstructures where cells will flourish.”
