Inverted photocuring 3D printing equipment

The invention belongs to the field of additive manufacturing, and particularly relates to inverted photocuring 3D printing equipment which comprises a projector, a forming assembly and a spin-coating assembly. The spin-coating assembly comprises a feeding pipe and a horizontally-arranged circular spin-coating disc, a discharging hole penetrating through the two faces of the rotating disc is formed in the circle center of the spin-coating disc, and the discharging hole is rotationally connected with the discharging end of the feeding pipe; the projector is arranged below the spin-coating disc, and the light emitting direction of the projector faces the spin-coating disc; the forming assembly comprises a forming table and a power part, and the forming table is arranged on the side, away from the projector, of the spin-coating disc and comprises a face parallel to and opposite to the spin-coating disc; the power piece is used for enabling the forming table to be close to or away from the spin-coating disc.
