The fixed housing 4 is provided with four sets, which are distributed in a matrix on the top of the printing rotary disk 3 and near the edge. Multiple sets of printing nozzles are provided on the printing rotary disk 3. Each set of printing nozzles can spray different materials, so composite material printing can be carried out without changing the material during the printing process.

[0026] In this embodiment, please refer to Fig. 3A wheel frame 401 is installed on the outer end of the top of the fixed housing 4. A forward and reverse motor 402 is set on the outer side of the wheel frame 401. The output end of the forward and reverse motor 402 passes through the wheel frame 401 and is connected to a transmission gear 403. A rack and pinion rod 404 extending outward is slidably connected inside the fixed housing 4. An electric push rod 405 is fixed on the outer end of the bottom of the rack and pinion rod 404. A push plate 406 is connected to the drive end of the electric push rod 405. A feeding cylinder 407 is set below the electric push rod 405. A feeding piston 408 that works with the push plate 406 is slidably connected inside the feeding cylinder 407. A connecting bracket 409 is symmetrically arranged on the top of the outer side of the feeding cylinder 407. A printing nozzle 410 is connected to the bottom of the feeding cylinder 407.
