Safety Instructions

Please view following matters before using the 3D Pen

Please pay attention to electricity safety when operating! Do not use this product near bathtub, hand wash basin, bathroom, or other place with water, otherwise it may cause death because of electric shock! Please unplug the power supply in time after using.
This pen tip may cause burns after heating, please do not touch pen tip or any part near it.
This product is suitable for over five-year old children and adults. Children should use this product under adult’s supervision.
This product is not waterproof or breaking proof. It is forbidden to use the pen tip to stick any hard objects. It is also forbidden to insert any other objects into the loading port or into pen tip.
Consumable filament for this product: SL 300 PLA & ABS; Filament diameter 1.75 ± 0.02mm. Please use original filament. It might cause damage to the product if choose non-original filament.
When using this product at the first time, it’s normal that a little smoke comes out from the nozzle, which won’t affect the product using.
After finishing using this product, please ensure to unload the filament and cut off power supply.
All of the products will pass qualified testing before delivery, so it’s normal if there are a few filaments left in the nozzle. Please feel free to use.
In order to ensure continuous using, it is recommended to cut of power supply to stop for ten minutes after one-hour continuous using, then back to use.

Operation Instructions

Power on

Use the 3D Pen data cable to connect with DC 5V 2A extra power or power adapter. When word show on LDC screen, it means power on.

Filament Selection/Preheating

Click “Filament Option” key to select PLA or ABS according to the filament you are going to use.
Click “Load” key, the red light is on, it means the device is preheating. (Preheating time is around 70-100s). The preheating temperature will be showed on LDC screen. When the red light turns to green, it means preheating is over.

Load Filament

When the light turns from red to green, it means preheating is finished. Now you can select one of the two ways below to feed in the filament: (Attention the filament: PLA, ABS)
A: Click “Load” key.
B: Double click “Load” key and press it constantly When the motor start to work, feed your filament into “Filament loading port”. Once the filament was extruded from nozzle, you can start drawing. (Click “Load” key, the motor will unload the filament about 2 mins. If there is no clicking operation when the pen is working, it will enter into sleep mode automatically every 8mins. If you want to continue using, just click the “Load” key.)

Working Speed/Temp Adjustment

For speed adjustment first click “Pause” key to stop extruding. Then click “speed +/-“ key to choose the speed you prefer. You can adjust the speed from 1-8 grades. Grade 1 is the slowest, grade 8 is the fastest. Finally, click “load” key to extrude filament again.
For temperature adjustment firstly click “pause” key to stop extruding. Then click “Temperature Adjustment +/-“ key to choose proper working temperature. Finally, click “load” key to extrude filament again. (Remark: Same filament’s melting point will be different as its colour difference. Please adjust temperature according to the situation. For filament melt points and temperature adjustment details, please refer to Temperature Adjustment Instruction.

Unload/Replace Filament

When the light is green, press the “Unload” key for 3 seconds. When the motor starts working, release the key, the filament will be unloaded automatically. When the filament stops retreating, please take the filament out of the “Filament Loading Port” gently. Press “Pause” key to stop the motor. (Remark: the motor will stop working automatically and be in dormancy after continuous unloading for 50s.) If you want to replace filament, please refer to below SPECIAL NOTICE.

Finishing Drawing

When you finish drawing, please unload the filament, and cut off the power.

Trouble Shooting

Please follow the below instructions if any detect happened. If still could not solve the problem, please contact with the distributor whom you bought the 3D Pen from.

Defect phenomenon	Causes	Solutions
LCD screen is off	Adapter breakdown	Change the adapter
USB cable breakdown	Change the USB cable
Red & Green indicator light is flashing	Low-powered adapter	Change the

adapter
Low-powered power bank| Change the power bank
No filament comes out from nozzle tip| Too little filament comes out| Increase the speed of extruding filament
Low temperature| Increase the temperature
Slip on the gear| Unload the filament then load with new filament
Filament loading failed| Unload the filament and make Sure the end of the filament is flat
Poor contact on the nozzle| Take apart the nozzle and re-install again
Extruding filament with bubbles| Decrease the temperature
Blocked nozzle| Increase the temperature and speed to squeeze the remaining filament out
Defaults in use of PLA mode| ABS filament remains in the pen| Re-connect the 3d pen again, and turn into ABS mode in the highest temperature, then load the PLA filament until the PLA filament comes out from nozzle
Unstable filament flow
Blocked nozzle
ERR displayed on the screen| Temperature is too high for PLA mode| Unplug and cool down the pen for about 3 minutes then plug the pen
Nozzle is loose| Take apart the nozzle and re-install

Instructions for temperature adjustment

Due to filaments’ different melting point with different colours, in order to improve the quality of creation, please follow below suggestions:

In use of PLA or ABS, if the filament is “cracking”, it means the temperature is too high, please try to decrease the temperature by 8-15°C using “Temp adjustment – ”key.
In use of PLA or ABS, if there are too many bubbles, it, means the temperature is too high, please try to decrease the temperature by 3-8°C using “Temp adjustment -” key.
In use of PLA or ABS, if the extruded material is in dull colour, it means the temperature is too low, please try to increase the temperature by 5-10°C using “Temp Adjustment +” key.
In use of PLA material, if the extruded material is runny to drip, it means the temperature is too high, please try to decrease the temperature by 10-15° using “Temp adjustment – “key.
The normal extruded material should be smooth, mellow without bubbles (little bubbles are OK).
