Fuse Filament Together - The Cheap Way!
ฝัง
- เผยแพร่เมื่อ 19 ต.ค. 2021
- One annoying thing in this hobby is having a little bit of filament left on a spool that won't be enough for a full print or running out of filament mid-print. In most cases, you have options when this happens and one of those options is to fuse, or weld, partial rolls of filament together. In this video, I show you how to do that the cheap way using just a heat source and tube. I will make another video soon going over how to use a product that was designed for this and talk about which option is easier in that video.

I hope you found this overview helpful! If you have any questions or would like other tips/tricks, just let me know in the comments.
2 years late, but I can't tell you how frustrating it was to go through almost 7 minutes of talking and not doing anything before you got into what I found the video for.
Hi, thanks for the feedback. I was trying to explain the why and how first. @@Crymus
Thanks you saved a print of 36 hour
Hi. Im glad i was able to help :).
another 36 hours for this video 🤣
8 minutes in until he actually does anything. that algorithm is boss.
Hi. Sorry i was trying to explain what/why i was doing.
Wanted to comment that this worked VERY well! Thanks for the tip! Spinning the PTFE tube helped alot. I was using a butane torch and it was too much, I used a lighter instead and it worked perfectly. Thanks!
Glad it helped!
Thank you so much for this video! I have a print that has been going 24 hours... and appears to have another 24 to go. I deeply appreciate this video because it may very well save that print... if I'm home when it starts to run out.
Hi. Thanks for the feedback, i hope it helps. Its really useful for longer prints like that.
Great information, and very well presented.. I have several rolls with just a layer of filament on them. This would be great to combine it. IF you add the leftover of each roll onto what is being combined, after awhile you will have nearly a roll of accumulated leftover filament.
Hi. Thanks for the feedback. I know several people that make spliced rolls like that, it just takes some time to do.
Just tried it. Got lucky after 3 attempts. Thanks! 👍
You're Welcome
Great info, was trying to do it another way, that wasn't working, but never thought of using the sand paper to trim it down. I did find however that ithe sand paper can make the filament hot again, and ruin the fusing point. There's a tool called card scraper (or card shavers) used by carpenters that can be applied in place of sand paper. Instead of sanding the filament, you're shaving it down with little/no heat build up, and the fused point remains strong. The cards come in large and small sizes, and I find that the smaller ones do a better job of whittling down the section.
Hi, thanks for ethe feedback and tip. I will take a look at those.
This worked so well. Good video thanks for the help.
Thanks for the feedback.
Tutorial starts at 8:07
Thanks for sharing.
Thank you for a great tutorial. I specifically like it that you pointed out that one needs to practice as it WILL fail if one did not practice properly. Though you did not mention it I just assume that you were using the PTFE that is used in the Bowden filament feed system. 😉
Hi. Thanks for the feedback, ya that is what im using.
i cant see in the comments, but what tubing did you use to connect the pieces? Any idea where i could find it in the UK or Amazon website?
Excited to try it. Think i've got a roll or 2's worth of PLA saved up if i can use this method
Hi. I used Capricorn Bowden PTFE Tubing, it should be available on amazon in the UK. There is a link to it in the video description.
@@3DPrintscape man I feel an idiot 😂 didn’t realise it was a Bowden tube. Will sort one now 😃 thank you for the speedy reply!!!
That was great. You are the one, man!
Glad you enjoyed it!
nice it works
Hi, Its a pain at first but once you get going it gets easier.
Good info.. way too much preface- was the 45° cuts effective after you melted off the first 1/2" ?
Thanks and it was. I ran several test prints using spliced rolls without much issue.
What do you do with the piece of tube once fused? Can’t slide it off can you, so where does it end up?
Hi. It depends on the application. If your fusing the filament to something thats curranty printing you would just leave it until the print is done and you remove the filament. If your fusing multiple spools together, you would remove it when rolling up the spool.
What temp were you running your heat gun at?
Hi. Im not sure, its just a cheap heat gun so the options are on or off lol.
What kind of tubing are you using and where to buy it from???
Hi. Im just using a piece of capricorn tube, you can get it on amazon. I have a link in the video description.
Would have been nice to say what size tubing your using
Hi. Sorry its standard tubing for the ender 3. The ID is 1.75mm.
Great tutorial I’ve fused filament without using a piece of ptfe so I’ll try again using this method to see if I get better results 👍
Hi. Thanks for the feedback, let me know how it turns out.
NICE it WORKS !!!!!
Hi, Its a pain at first but once you get going it gets easier.
followed this video to the letter made sure there was no resistance on the ptfe tube after and it would feed in my direct drive extruder up unit the spice and then stop feeding it please advise
Hi. It sounds like the diamide may be too thick at the fuse. Try to use the tube more when fusing it or sand it down a little.
if u mean roll the tubing as im joining it i do that already
and im not sure why it wont feed through my direct drive extruder as its the same thickness@@3DPrintscape
If its too thick at any point it wont feed through. Maybe try to measure the area around the fuse to tell you for sure. @@danachristie3862
I can't sand it too much or it just breaks apart
Gotcha, it can be a pain to get the process down at first but it does get easier@@danachristie3862
I have a idea to cut a v shaped notch in The ptfe tube and then heat the filament
Hi. That’s an interesting thought. Have you tried it out, if so how does it work?
I wonder if you can use a brass tube instead of Teflon.
Hi. If the diameter is right, i dont see why that wouldnt work.
How's the hatchbox filament working for you?
Hi. It has been working out good, i havent had any issues with it at all.
@@3DPrintscape awesome. I have been using mostly esun and polymaker with some overture thrown in the mix. Always looking to expand filament options.
@@bleach_drink_me I also like overature as well, but for the price hatchbox is my typical go to.
@@3DPrintscape thanks for getting back to me. Will throw some in my next order.
I have used gizmodorks it clogged my printer . Then I found hatchbox and it works without clogging
I have been thinking about this because I use an inordinate amount of filament in test prints, where the colour isn't that important, and I have a number of end-of-reels with just a meter or three of filament on them, Getting a strong fuse that isn't too big seems to be the problem - if the join is slightly thinner than 1,75mm then that might be less of a problem. I'm sure there must be a simple solution, and this seems the simplest so far.
Hi. its a pain at first but gets easier with practice. There are some more expensive tools that say they do the full process for you but the reviews seem mixed on them.
@@3DPrintscape Yes, I spent some time thinking about how to make a joining machine, but there are so many potential points of failure or things you'd have to get made accurately that it doesn't seem worth the effort for something you're not doing on a daily basis. And as you say, the reviews of some quite expensive commercial offerings are not encouraging.
where do you get the tubing though
Hi. Thanks for the feedback. The firmware has worked for most people, if there was an issue it was typically with the wiring for the bltouch. What board do you have, what firmware did you end up using, and did you add a bltouch (if so how was it wired)?
It looks like regular PTFE tubing, so just snip off a piece of what you have on hand
@@kevinj7188 Ya its just regular PTFE tubing, nothing special.
will a lighter work? i dont have a heat gun
Hi. Yes a lighter will work, and if you have a good one that will stay lit, it will work better than the heat gun.
💕👍
So now you have a piece of PTFE tubing stuck on the filament. Fine if you are welding tiny pieces of filament, but pretty useless if you are spooling on long pieces.
Hi. That is true, i mentioned it in the video as well.
ITA NEW RECORD - Dude rattles on for 6+mins before he gets to even 1/2 a point
Hi. Thanks for the feedback, its hard to balance the how and why some times.
they should really invent a shrink tubing for this application
Hi. Ya that would be nice.
Overheating PTFE releases fluorine gas, which can ruin your whole year. Just saying.
Hi. Interesting, do you know at what point it does that? I was trying to not heat the tube much.
PRO TIP: Hold the 2 pieces side by side (parallel) and make your 45 cut. they will then be identical......... You're welcome
Hi. Thanks for the tip
Start the video at eight minutes❤
Thanks for sharing
well that wasn't too terrible.
Hi, Ya its not too bad once you get the hang of it.
it's starts 7 mins in , for those who are not complete idiots
Hi. Thanks for sharing.
Video starts @8:00
Hi. Thanks for sharing.
To the point: 6:55
Thanks for sharing.
I've only had a 3d printer for a bout 5 months and only got to the point where I had to start welding filament 2 months ago. I watched a few videos on using various tools and I actually stumbled upon the method you show with the PTFE tube by chance. I outright refused to pay for a tool if I could figure a way to do it myself.
I did find 2 tricks that helped me have better results: First, use a tube with as close an inner diameter as possible. I had a section of Capricorn tube left over that was a tighter fit to the filament than the older white tube. This took more practice but it gave me better results with less trimming afterwards. Secondly, use an xacto knife (#11 blade) to bevel/chamfer the inner diameter of the ends of the tube. This makes it easer to feed the filament into the tube which can be a real help when they are molten.
Hi. Thanks for sharing your tips. I will try them out next time i do this.
Nice video. Would be great if it didn't take 6 minutes to get to the actual meat of it.
Sorry about that
Why not just buy a new roll of filament?
Hi. Its more about not wasting as much filament than the cost, at least to me it is.
Do yourself a favor and skip to the 7 minute mark - it takes that long to even start showing you what's up
Hi. Thanks for the feedback.
I don't bother fusing it; I just cut both ends flat, hold the tips together, and carefully guide them into the extruder until it's grabbed the new filament.
Hi. If your by the printer when the filament runs out thats an option. Im not sure if its easier though, it can risk causing other issues with the print.
Not going lie Jesus so much talking for a 2 second join
Hi. Thanks for the feedback.
too much talking its very boring
Hi. Thanks for the feedback. I was trying to balance everything out and still explain what im doing.
Way too much talk and explanation. Most that find the video already know why they are here...
Hi. Thanks for the feedback.
12 minutes of talking to show 30 seconds of fusing. Cool.
Hi. Thanks for the feedback. Its difficult to find the right balance between explaining and actually doing. I have had other comments on video saying that im going to fast and dont explain things enough.
