How to Remove Filament From a 3D Pen?

To remove filament from a 3D pen, wait until the pen indicates it is safe, then gently pull the exposed filament end.

Based on the provided information, here is the process:

Steps to Remove Filament

The key indicator for safe filament removal is the status of the pen's lights.

1. Check Pen Status: Ensure both LEDs on the pen are solid green. This indicates that it is safe to proceed.
2. Gently Pull Filament: Once the LEDs are solid green, it is safe to gently pull on the exposed end of the filament that is outside the pen.
3. Remove Filament: Continue pulling gently until the filament is completely removed from the pen.

Reusing Filament

If you plan to reuse the filament you just removed:

• Snip the End: Remember to snip the very end of the filament before attempting to reinsert it into the pen. This likely removes any melted or deformed tips, ensuring smooth reloading.

Following these steps, based on the reference, allows for safe filament removal from your 3D pen.
