Features: Lightweight 3D pen, no burden using and carrying. Intelligent control, even amateurs can freely paint. The advanced nozzle with intelligent temperature sensing and heating function, and with low tip temperature. 8 digital speed controllers for more precise and stable extrusion. A single press can continuously squeeze the flow, making it easier to graffiti. Built-in nozzle for easier maintenance. Specification: Type: 3D Printing Pen Kit Model: The 3rd generation Recommended temperature: for ABS filament: 180-210℃, for PLA filament: 160-180℃ Support material: 1.75mm PLA / ABS Equipment output rated power: DC12V 3A 36W Weight: Approx. 321g Size: Approx. 17.5 * 2.5 * 2.5cm Package list: 1 * 3D Printing Pen 1 * Power Adapter 1 * Pen Holder 1 * Drawing Template Paper 1 * User Manual 3 * PLA Filaments(Random Color) Note: 1. Please note that the PLA filaments are shipped in random color. 2. Please allow slight error due to manual measurement. Thanks for your kind understanding. How to Use the Pen: Connect the adapter to the power source, then insert the end of the adapter's wire into the power hole of the 3D pen. The LED light is yellow to indicate that the device is turned on and enters standby mode. 2. Material / Filament Selection After step 1, the LED screen displays ''PLA'' or ''ABS''. Press ''Material/Temperature Button'' to select the type of material you are using. It must be the material used. The wrong choice may cause potential malfunction. (Note: This device can extrude wood and work in ''PLA'' mode) 3. Warm up After selecting the material, press the ''Feed button'', the LED light is red, indicating that it enters the warm-up mode, and the LED screen displays the real-time heating temperature. When the LED changes from red to green, you can start graffiti with the pen when the warm-up process is over. (It takes about 30 seconds to warm up.) 4. Select the drawing speed Press the Speed ??Control button to select the most appropriate drawing speed. (Note: 8 digital speed controls are from 1 to 8, 8 is the fastest.) The processing speed button ONLY works when the drawing is stopped and the LED light is green, and in other cases the processing will be futile. 5. Loading Insert the selected material into the feed hole at the end of the pen and press the ''Feed Button'' and the filament will be moved by the built-in motor. When the molten material comes out of the nozzle, it means the setting is successful, you can start graffiti now. 6. Create your work The device is designed with 8 speed controls. Please select the appropriate drawing speed before graffiti. Different types of filaments have different melting points. Please adjust the temperature in time according to the extrusion status. 7. Extrusion flow function Press the ''Feed button'', the pen continues to squeeze out and flow, press the ''Feed button'' again, the pen stops feeding. When the pen is used continuously for 8 minutes, the pen will automatically stop feeding and extruding. 8. Replace/unload materials When the LED is green, press and hold the ''Unload button'' for 3 seconds, then release and the built-in motor will begin to remove material. When the material stops moving backwards, gently remove the material from the end of the pen and press the ''Unload button'' and the motor stops reverse. (Intermittent fun moves will stop automatically after 1 minute of work) 9. Finish the work After completing a drawing, remove all filaments to avoid adversely affecting the normal use of the device in the future. (Note: The device is sturdy and the equipment is great, but like all machine tools, rest after an hour of continuous use to extend its life.)
