I was getting rid of some spool ends the other day by manually feeding them in while printing. That way I was able to push all these ends past any sensors and into the extruder for uninterrupted printing. It came out fine but was quite tedious.
So this got me thinking: Do any of you guys splice filaments? Not only would this allow for more efficient material use, but I suspect a print made from a bunch of small segments of different colors could look kinda cool.
I’m primarily printing with PETG, so my question is specifically about that, but I’m sure the concept should work for other filaments too.


Yep. I think other manufacturers do this with multi-material units, too. It’s a really clever way to handle the issue and one of my favorite features of the AMS. Spool running low? Just throw a second one on there, tell the printer they’re the same material, and bam. Wake up the next morning to an empty spool and a completed print.
