S50：Vertically unit reduces the moulding cylinder one by one, repeats S30-S40, and the personalization artificial tooth successively increases,
The height of one unit is equal to the thickness of the cross section tunic；
S60：Personalized artificial tooth embryo is obtained, it is post-processed to obtain finished product zirconium oxide artificial tooth.
10. the method for 3D printing zirconium oxide artificial tooth according to claim 9, it is characterised in that：It will be extra in moulding cylinder
Zirconia slurry is collected and is recycled in the slurry cylinder, it is recycled.
