Claims16
A composition for 3D printing comprising magnetic particles having at least two magnetic domains, wherein the magnetic domains are irregularly arranged when an external magnetic field is absent and are magnetized by an external magnetic field, and a thermosetting resin, wherein the magnetic particles are vibrated by magnetization reversal, and
- wherein the magnetic particles satisfy Formula 1 below:
- MXaOb [Formula 1]
- wherein, M is a metal oxide, X includes Fe, Mn, Co, Ni or Zn, and |a×c|=|b×d| is satisfied, where c is the cation charge of X, and d is the anion charge of oxygen, and
- wherein the magnetic particles have a coercive force in a range of 1 to 200 kOe, and wherein the magnetic particles have an average particle size in a range of 20 to 50 nm.
