Rotational 3D printing spins out stronger structures

Harvard engineers have demonstrated a new 3D printing technique that allows the arrangement of short fibers in the printed material to be finely tuned. The spinning printer head gives the technique the name "rotational 3D printing," and according to the team the fibers in the ink can be arranged in different orientations at different parts of the printed object, in order to boost its strength, stiffness and resistance to damage.
