Is it possible for the leftover residue, of tape on a spool to be scraped into the feed? As the filament drags over the edges of the spool?
Honestly , I just clip the 2-3” off the front and not worry about it. It’s a minuscule amount of plastic
If you’re trying to be ultra frugal, yes, you can probably clean it off with a solvent. IPA might work. Goo gone would but introduces all sorts of other contaminants.
I admit I tried using every gram. Still I found some of the tape residue on the inside of the spool. Thanks for the advice.
I mean, honestly, it’s commendable.
I’d try IPA for the stuff in the middle. Or something like those blue 3m scrubbies.
Apparently goo gone has limonene in it, I’d be wary of putting it anywhere near filament depending on the plastic used. I’m personally on the side of clip it and be done, I try to use as much as possible as well, have had the tail out on some spools get caught in the reverse bowden I use depending on the way its been wound, so I do tend to be on the cautious side and why I have smart filament sensors. Would rather lose 5g of filament over failing a print and wasting even more.
Yeah, technically it could, but tape sticks really well to most filament. It is more likely that whatever came out of the nozzle was in a dead zone. The nozzle back bore is drilled with a steeper angle than a typical bit, but it is not so acute that there are no dead zones. Sometimes filament can sit in those zones, cook, and go wonky. It happens more often with high temp filaments like polycarbonate. I run a bit of purging filament with every change and rarely have problems.
I would be more concerned about extruder gear issues with residue over time.
Glad to know. I wasn’t aware of dead zones unil now. I’ll have to research that.
Would it really cause problems if it did? I’m thinking if it got into the hotend (especially at the small amounts we’re talking about), it would probably just melt into the molten filament and not really cause any issues.
There are “filament filters” that are for keeping foreign materials from getting into the hotend, but they’re more for particulate things that won’t melt and might clog the nozzle. Tape residue (again, at such small quanties) surely would just flow through with the molten filament and be unnoticeable in the final prints.
I guess it would be small. What about a small triangle of it?
I’m asking because I got a weird droplet in my feed that showed up in a duplicate print.
A small triangle of tape, or just tape adhesive?
I’d definitely be more inclined to think tape could be more of a concern than jist the adhesive. Probably if it were me, I’d just try to be more thorough about removing all the tape from the spool (and not worry about small amounts of residual adhesive.)
Also, a description and/or picture of the filament and tape you’re talking about could help.
Heads up btw, I’ve found that a good way to remove sticker residue on comic book bags/boards is to take the peeled sticker and use it to “blot” up the residue. It’s possible that may work for you with the filament. Idk about your actual question though, seems like it’d be possible.
