Does anyone have experience trying 3D printing pen "ink" in a printer?

Does anyone have experience trying 3D printing pen “ink” in a printer?

There are lots of small-coil color packs on Amazon aimed at 3D pens. I’ve found very few other sources of smaller plain-old-PLA spools/coils for printing; I’d like a stack of colors to use for “final” prints of parts I’ve prototyped in black. GlobalFSD is great for exotics, but not colors.

My biggest concern would be that manufacturing tolerances would be a lot lower since pens are for humans, not robots.

There’s no difference, other than some of the filament for the pens comes as straight pieces.

I don’t see that being a problem. They still have to feed well, the pen’s feed mechanism is still reliant on being somewhat consistent. The sticks are pretty expensive for the amount that you get though. Depending on the brand, you’re paying $10 for 50g.

People use normal spools with those pens all the time. $5 filament has a lot of colors and comes in $200g spools

@Griffin_Paquette ​ Wow, $5 filament is exactly what I was looking for. Thank you! I don’t know how I hadn’t seen it before.
