摘要: An air nozzle for 3D printing, and a multi-channel telescopic valve provided with the nozzle. The printing comprises hollow structure (80) (60) printing. is divided into an sealed section (802) discharging (803). (62) projecting (63) fitted to (802). surrounds outer side of also mounting base (10), cylinder (20) needle (30). disposed at tail portion (20). below (10). have uniform output, high precision low energy consumption noise, environmentally friendly saving.
