3d A laser printing apparatus and a printing method of food

A laser printing apparatus and food 3D printing method, comprising a bracket body, the bracket body is provided with a transmission section, feeding means, said transmission portion includes an output shaft both ends of the shaft extension stepper motor, stepper motor biaxial stretch are connected via a coupling of the first bevel gear and the second bevel gear, the first bevel gear is connected with a first screw, a first screw is provided with a first slider, a second wire is provided with a second bevel gear bars, the screw is provided with a third on the second spindle between the second slider, the first slider, the second slider is provided, on a third slide is provided with a third screw rod, a third bottom portion of the slider a shower head and a laser; substrate disposed below the nozzle. The present invention, since the stepping motor shaft extension, using biaxial stretch motor with bevel gear transmission and screw to achieve, since the two driving wheel is driven by the same motor shaft, synchronization, and will not be inconsistent caused by the left and right velocity skew phenomenon. The present invention is simple in structure, easy to implement.
