Abstract: Disclosed are 3D printing equipment, a system, and a method for food design and production. The 3D printing equipment has a bipolar microwave heating antenna for focusing heating on a material in an extrusion nozzle. The extrusion nozzle is between the anode antenna and the cathode antenna of the bipolar microwave heating antenna. The anode antenna and the cathode antenna limit a microwave electric field between them, thereby implementing focused heating on the material.

Abstract: An imprinting apparatus includes an imprinting platform having a first side and a second side opposite to each other, an imprinting roller disposed above the imprinting platform, a transfer module, and a film separation module. The transfer module includes a transfer film located between the imprinting roller and the imprinting platform and a fixed frame fixed beside the first side of the imprinting platform and a movable frame disposed on the second side of the imprinting platform that clamp opposite sides of the transfer film. The movable frame is adapted to move horizontally relative to the fixed frame to change a flatness of the transfer film. The film separation module is connected to the movable frame, and is adapted to drive the movable frame to be turned from a first position to a second position, such that a rounded corner is formed between the transfer film and the imprinting roller.
