The 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 does not require computer or computer software support. You just need to plug it in and wait a while to start your wonderful creation. The copyright belongs to the author.

Take the low-temperature 3D printing pen as an example. 

1. Connect the power supply with output power of 3.7V  (it can be a mobile power supply or a 3.7v plug, which can be directly plugged into the computer), and the power indicator is bright yellow; 

2. Click the wire feed button, the heating indicator lights red, and the pre-heating starts;

 3. The heating indicator turns green, the pre-heating is complete, click the wire feed button, and add the consumables to the feed/return port; 

4. Extrude the consumables out of the outlet and start painting; 

5. In the process of wire feeding/unwinding of the 3D printing pen, click any button to pause, and click wire feeding/unwinding again to continue; 

6. Click the rewind button, the consumables will automatically exit the inlet/outlet port; 

7. In the process of using the 3D printing pen, we must ensure the flatness of the ends of the consumables, whether it is to renew or change the filament. The copyright belongs to the author.

Through the analysis of the internal structure of the 3d printer pen, we realize that the side suction of the 3d printer pen will cause troublesome cleaning and loud noise. To solve the problem of fume escaping,Kegumotor designs the intelligent drive system for the 3d printer pen. The drive system automatically senses the amount of fumes through the fumes sensor and realizes the intelligent upward and downward movements of the 3d printer pen through the forward and reverse rotation of the screw. 

The intelligence of a single product is the initial stage of the home appliance. The coordinated linkage between products can create a better user experience. In this regard, Kegumotor R&D center of gear motor for 3d printer pen expands the exploration field of home appliance products.
