3Doodler Flow Pen FAQs #
What type of filament can be used with the 3Doodler Flow pen?
The 3Doodler Flow is designed to use 1.75mm spooled filament. However, as the Flow’s temperature is adjustable, this opens up the ability to use 3Doodler Flow refills OR your favorite brand of 1.75mm spooled filament that prints/melts within the range the Flow provides (160° to 220°C).
Please note that we are unable to guarantee the quality, safety, or compatibility of any third-party filament.
Why is my 3Doodler Flow pen not heating up? I just see one Flashing Green LED and one Solid Red LED
Be sure you have select the temperature setting you wish to use. This setting should correspond with the type/material of filament you’re planning to print with (PLA for PLA filament, ABS for ABS filament).
When you plug in the pen, you’ll see a Flashing Green LED and a Solid Red LED. Look at the display — it should say “PLA” on it. If using PLA filament, you’ll need to select PLA by single-clicking the FAST button. If using ABS filament, you’ll need to click the “+” button to scroll to ABS and THEN single-click the FAST button to lock in your selection.
The pen will then begin to heat up, and the display will switch back and forth between showing the target temperature and the current temperature. Once it’s fully heated (both LEDs Solid Green), you’ll be all set to doodle away.
The filament is moving slowly. What do I do?
Sometimes, when you get to the end of one strand, extrusion slows noticeably. Put a new strand into the back of the 3Doodler pen. If it still extrudes very slowly (or not at all), try giving the new one a little nudge down, and that should do the trick!
Why is my 3Doodler Flow having difficulty feeding/gripping a new strand?
Sounds like you might have a jam. Follow the instructions in this Video Tutorial to clear out any clogged filament. If that doesn’t get you back to doodling, contact us, and we’ll help troubleshoot the issue.
What are the “+” and “-” buttons for on the 3Doodler Flow?
These buttons have two functions. First, they are used to cycle through the temperature setting options (PLA or ABS).
Additionally, once a temperature setting is selected, these buttons adjust the temperature to the degree (within the range of the selected setting). If you’re using 3Doodler Flow refills, you won’t need to adjust this setting, as the default temperatures are optimized for our filament spools.
My Flow 3D Pen is broken. How do I fix it?
This could be a number of things. Check out our troubleshooting guide to walk through possible issues.
My 3Doodler Flow sometimes makes a slight crackling sound while extruding. Is this normal?
If the filament makes a slight crackling sound while extruding, this is totally normal. It is caused by moisture escaping from the strands (that has been caught in the strand since fabrication). This is not dangerous or a cause for concern!
