Refrigerant 3D printing pen

Abstract

The invention discloses a refrigerant 3D printing pen. The refrigerant 3D printing pen comprises a needle cylinder, a nozzle, a silica gel piston, a piston, a needle cylinder cover and a screw rod, wherein the nozzle is arranged outside the needle cylinder, the piston is arranged in the open end of the silica gel piston, and the screw rod penetrates through the needle cylinder cover and the silica gel piston to be mutually assembled with the tail end of the needle cylinder. The inner discharging end of the needle cylinder is provided with a switch key for controlling an ultraviolet lamp to be turned on and for starting up under the standby state. According to the refrigerant 3D printing pen, a normal temperature material is adopted and is cured by the ultraviolet lamp; a motor rotates for driving the piston to move forwards to extrude the material, and the material is extruded out of a needle cylinder opening; and the speed of the motor is controlled by using electronic hardware and software, then the purpose of controlling the discharging amount is achieved, and the control mode is simpler and more convenient.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a refrigerant 3D printing pen. Background technique [0002] 3D printing pen is the world's first pen with 3D printing function. Using PLA and ABS plastics, the 3D printing pen can "write" on any surface, and even draw directly in the air. It is compact and requires no computer or computer software to support it. However, when the current printing pen is discharging, it has a very complicated transmission structure, which makes the structure inside the pen very complicated, and the production cost will increase accordingly. [0003] Generally, the PVC glue is processed by heating, which has the risk of scalding, and the burning process will produce toxic gas, so the 3D printing pens in the prior art still have deficiencies. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a refrigerant 3D printing pen that does not requir...
