There's finally a commercial version of this?! No dead Kickstarter or a bunch of projects I have to translate from Russian?! oooooooooh! Now I can take all my PET filaments and join them
That will be the test! Unfortunately the unit only goes upward to 240C - PET1 needs a much higher temp for joining. Time will tell if it'll be able to be a mod.
Yeah, not happening because they won't make one that operates at PET melt temp (at least 270 for effective weld, 280+ preferred) because they're using PTFE which offgasses dangerously at 250.
The Slunaz ff1r exists. Pretty expensive though.
@@danh6720 Isn't it still a printed kit not a product you can use out of the box?
@@daliasprints9798are you talking straight PET? Cus I do PETG at 235-240 and get complete glass transition.
"I'll take care of him later" I'm picturing Jeremy 3d printing six tiny "cement" shoes for that insolent fly.
Where’s Lawrence? You told me to take care of him.
Stoked to see a dedicated device for this! I gave up on trying to weld filaments with janky half baked home solutions in favour of just using up the leftovers on machines with run-out detection. After watching this I still think I'd opt to just continue doing it that way
Hi James 😂 Now what I need is a way to transfer the remaining filament from one spool to the other - in a convenient way 🤔
Even with run-out detection on my printers, I like this since I don't have to babysit the printers. And, for $35 intro pricing, it's an easy add to my toolkit.
Audio tape splicing circa 1977! Thanks, Jeremy and well conceived, #SUNLU! Calendar reminder set for the 14th!
😂 “there’s a fly on my hand. I’ll take care of him later.” 🤣🤣🤣🤣.
And I did. ☠️

Hi, there.
Could you try testing with a more multicolored piece? Since slicers show us how much of each filament will be used, we could measure each color involved, cut the filament in the right spots, glue them together, and then load it into the printer. This method might not work for very complex objects with frequent color changes, but it could be worth trying for simpler projects like lightboxes.
Thanks!
The only bad thing I can see about this is the non reusable plastic connectors. If they could get rid of those it would be ideal.
Seriously. I wish it had some sort of steel half pipe sandwich with the correct diameter. Something that had cutters built in to get the right shape and then just put it in, let it melt, cool, and voila.
@@KJMcLawsI also would prefer that
They are not recyclable?
@@mikekiske They seem to have to be cut to get it off. Wonder if the molten filament would ooze out if you reused a cut one or if you could get away with it depending on the filament.
@@scarfire87 probably loose it's shape
First time watcher, the "Bort" license plate is amazing. I love the review. Subscribed.
Thats pretty cool! I've tried doing this with a candle and a PTFE tube, what a pain. This looks WAY easier!
Putting fire to PTFE might be VERY unhealthy. Please don‘t.
Cool! I was literally talking about what to do with old filament yesterday with a buddy. We both picked up the flashforge ad5m and already have maybe 5 'almost useful' rolls sitting in the corner 😆
100% getting this. I use a lot of the same 3-4 filaments and hate when I only have a little bit left on one. This will let me attached some of a smaller batch onto a newer big batch without baby sitting it at the AMS unit when it runs low LOL
I like this, I have been doing the same thing by hand, a fishing guy showed this method on his channel. Just taking a piece of tubing (cheap) and a soldering iron works great, but this looks even easier; I will buy one tomorrow. BTW, this system works; no need to clean the filament of the spurs later. Thank You I just ordered this in Europe, should be here in 3-5 days €34,45 EUR this includes a 5% tip
Very cool, using a fiber optic fusion splicer as inspiration - I’m in!
I have subscribed to MANY 3d printing channels over the last five years. But, I watch a lot of your videos these days. Always lots of practical information. Subscribed finally. Keep doing what you are doing 😊
Very cool to see how easy it is to do.
Definitely picking one up. Thanks for this! 👍
It's really good to see something super useful like this to keep the 3D printing industry moving forward, instead of seeing yet another filament dryer from these companies
That's a neat device and reasonably priced too!
thank you 4 this detail demo and how respectfully you handle the equipment. I can't tell you how irretating it is to see some youtubers throwing things around to look "cool"
very nice demo.... thanks!
Great overview, it's cool that this kind of product exists now!
Ive been heating up a spare hotend block in a vice to hold it still, then push square cut ends to get it hot and melting, then shove both melting ends into of a ptfe tube. It works really well most of the time but its a pain having to drag the piece of ptfe tube the length of the reel to get it off before re-realing the filament into the spool. I will be buying one of these, Well done SUNLU. About time someone made something that works.
Definitely seems like a handy dandy little device; would come in handy for color transitions like you mentioned as well, as long as they're not required to be too precise :p
I needed this yesterday... I was working on a project that all needed white filaments. In trying to use all the bits, I had to babysit the printer to add more filament after one spool ran out.
Thanks for the overview. If this proves to be reliable I'll be getting one for sure.
Thanks for the overview. Great video, Jeremy!
You bet!
Just subscribed after watching your first video. Just wanted to let you know that your video was very informative, straight to the point, very detailed video. I have been in the 3d printer hobby for roughly a year with now 6 printers and over 140 rolls of filament. I have bought every filament splicer tool as well as diy printed ones out there to help consolidate the smaller used portions. None of the look as easy as the one you showed off. The others are cumbersome and aggravating to use, to the point that I have quit entirely of trying to splice them. Thank you again. Great video!! You’ve got a new sub from me!
Sounds like a nifty little machine. Thanks for showing it!
This plus a master spool (to be printed, of course) and respooler (also to be printed) are now in my to-do list
Neat! I do have a X1C with an AMS and it has a function to switch to the next spool once one spool is empty, super easy to finish off the leftover spools. I assume most brands will support this feature on their new ams as well.
That is what I do.
Same for me.
Why I ordered a k2 plus
This makes it easier that other solutions. I can't wait to take all my little rolls and make them one big one.
Oh yeah. Will be ordering this 👍👍
This is really cool. And completely sold out!
Excellent video. Nice overview and description without a bunch of nonsense and jibber jabber. Thank you
Oh this is great 👍 can't wait to get one
I really don't like that they just make you throw away the PTFE tube after every use. I love that finally someone is coming out with a commercial version of such a filament-welder, but I feel this method can be hugely improved on and that the price of this one is too high for what it does.
Excellent video. Thank you!
Thank you for sharing the video about SUNLU Filament Connector FC01! We're delighted to see users interested in our products. And we're truly grateful for your trust and support.
I'm new in the hobby and i didn't know what to do with the sample we got from our new printer, for 35 bucks it's not too expensive to save us from waste filament and let us try some new filament combine. Also i discovered you with this video, your channel seems to be promising ! +1
Great idea. Will have to get this
Love your videos, keep up the great work ❤
why oh why did they make it so that you need to continue to buy consumables. Why dont they reverse engineer a palette colour changer to see how they do it without the need for consumables :)
You know why, they know why, we all know why
that tube is the clever part - by doing the welding inside the tube, they don't get any flash lines that you've have from a two part mold.
It would be interesting to know if you can slide that tube off and reuse it. However, its quite possible that it's something like heat-shrink tubing so that it squezes the ends together.
@@ericthecyclistThe entire point of this is to mitigate waste though, adding in a ton of consumables winds up being as much or more hassle than just manually chasing the leftover filament into the printer with the end of a fresh spool. And flash lines really wouldn't matter, it would only create a very tiny flow inaccuracy in the moment that the joint goes through the extruder and nothing more.
@@bosstowndynamics5488 But how much waste is being produced versus how much is being eliminated?
With regards to flash lines, how much extra width in the filament does it take to clog things?
Presumably that tube also prevents the melted filament from sticking to the metal heating elements.
Hey, I had the same reaction when I saw that bag of tubes, but I recognized it solved some problems.
@@ericthecyclist Well, the produced waste is whatever flavour of high temperature polymer they're using instead of what is almost always going to be really cheap and relatively harmless PLA, so since the monetary cost is trivial either way I would say it's not worth it most of the time.
Flashing lines would not be large enough to cause clogs unless you're running your printer fast enough to push the extruder to its absolute limit (in which case you really shouldn't be using offcuts for those prints anyway) or if the mold is particularly bad.
The tube would prevent the plastic sticking to the metal, but it would just stick to the tube instead, so you could either use a polished nickel part (a 2 part metal sleeve would fix the cooling issue) or if there's no metal surface that could work you could coat the part in an appropriate polymer that would be reusable.
Most importantly though, I think this is a solution looking for a problem, there's so many ways to use filament scraps these days without a dedicated joining device and for colour changing it's really not that expensive to get a multi colour printer these days (or just insert a manual filament change when you slice the part, which is completely free)
This is awesome! Something we all struggle with when it comes to FDM printing! Thanks for sharing!!
Great video. Thanks for the explanation
Looks like a really good join 😊
So easy . Affordable . Thank you for knowledge ......
Superbe vidéo , très intéressant , je vais sans doute le commander , merci beaucoup Jeremy .......
There is mosaic pallete, there are run out sensors, there is mmu, and so many ways of mitigating this problem. I like its a low cost version of these.
If your present when the spool runs out and you have a sensor that pauses the printer, you can just feed a new filament right into the extruder. Just purge it a bit and your good.
Thank you for bringing this one to our attention!!!! Gained a sub!
Thanks a lot!
I see possibilities for a nice DIY project which uses my soldering iron as a heating source 💡
I can’t wait to get one 👏🏿
Great video! You made me want to get one😊
Was so stoked about this until the disposable splice sleeves part. They need a sleeveless weld or reusable metal sleeves that split apart when done.
Finally!!! I need this!
Reminds me of an old time film splicer. But for me personally I think my time is worth more than that 50 cents worth of filament on the end of the spool.
Interesting to see a non-homemade way of doing this. I have been using the silicone tubing and soldering iron method for a while now and you do get pretty good results after a bit of practice. I also printed the Pastamatic filament winder which is really necessary to not have tangles and failed prints afterwards. Winding by hand it just not feasible if you are trying to make an entire roll from all of your leftovers.
Really like your channel Jeremy!
Thanks! I appreciate that!
I just printed a ton of 800 gram parts leaving me with about 40 rolls of 200 grams... i ended up using them all for printing batches of small parts because there is always something to print at work, but i had to change the filament about every 2 hours. That worked because i work in the same office as the printers but for a print farm or unattended printers this thing seems pretty good.
You did a great job with this video… sharing it in my Facebook group.
Thanks for sharing!!
Awesome. Thanks for the vid.
this is an amazing product. No more wasting the last few turns of a reel. New sub BTW. Need to catch up on your back catalog.
Thank you!
Very good video. Thx
This is great. Can't tell you how many times I've tried to manually fuse filament ends together to use end of spools but am rarely successful at it.
Great video. Thanks.
Yes I'll buy
Do you need to rebuy the entire kit if you need a refill of the fusion splice sleeve? I don't see where to get refills ?
Very cool and awesome that it's only $35
I made a 4th of July print with red and a little blue on top of the lettering like this... you can estimate the length of filament needed my using the slider at the right on OrcaSlicer. I find that its just easier to watch it print (slicer gives a length and a time stamp) when the timer goes off then cut the filament and feed it directly into the extruder on my Ender 3 V3 KE. I own a 5m and a 5mPro but its just easier to use the Ender for multi color prints... I can't wait to see if flashforge comes out with a multi color system!
just ordered it
presale is already sold out! I want one! I have so many samples of the same color from ziro that i have a drawer full of them!
Only issue i have is that you need to use those sleeves, wonder how much they will cost. Happy to see some reasonable priced filament fuser.
At first I was thinking, this is neat, but hoe often am I going to use it, and then I took a look at the 6 almost empty rolls of filament I have and then I starting thinking of making my own mixed color filament. Yea, I will be getting one of these.
In the list of filaments, TPU was not there. It should be able to do 95A TPU right?
Will definitely be looking out for one of these. Thanks for the heads up
Nice review, good to get a jump on something like this prior to busy summer print season. I wonder how easy it would be to get additional "sleeves" or if there is a generic option available...Keep up the good work!
Hey im on the Cover!
theres other versions of this that are a couple years old that dont require those connector sleeves. they work just fine.
Nice! Not bad for $35
I just heat them with a candle and stick them together. It makes a little bulb where they connect and its easily trimmed. Works every time, and takes about a minute.
Are the transparent sleeves reusable, or do they become trash after use? How much do the sleeves cost when reordering?
That’s a good idea
Lerdge has a plier style design for it, but this looks nifty.
mkey...i get the idea but the engineer who build this was a little...
Why not use a 2 part metal cylinder that heats up? this would eliminate the need for that weird connectors.
I bet you could connect 2 filaments by just using any hot plate with the right temperature and than using the cutter to smoothen the filament if it gets blobby.
This is pretty cool. I just would like a similarly simple to use way to make Bambu poop and failed prints back into filament.
All about it, if it’s reliable and easy to use! ETA: only complaint is that you need a consumable to use it…. If you can buy like 500 of them for $5, eh not such a big deal I guess, but that’s the concern, especially if they discontinue the consumable item at some point
Have you tried reusing one of the tubes you cut off. I see in a reply that you were able to pull it off without cutting. Just wonder if you can get multiple uses out of one tube.
Thanks for the review. I’m curious about the filament clip that is visible when you show the fused red/blue filament feeding into the PTFE tube while printing (8:20 into the video). Is that available on one of the many model download sites?
Finally! Good video as well. Thinking it's time I subscribe....
On the paper it would be perfect for PET recycling. But i wonder what is the max temp it can go. And do you necessarily need to cut the ptfe tube ? Can't you not slide it ?
I have been able to slide it off as well with a little effort.
Feels poorly (and overly) engineered and overpriced. The most important part is the PTFE tubes with correct diameter. I would buy a bunch and just fuse filament together with my soldering hot-air gun. Unfortunately, I didn't find any 1.75mm PTFE (or other material) tubes for sale, there's only 1.9 ones.
I found some 1.8 mm ID ptfe, but it's too big, that nominal 0.05 extra create a bulge that results to be problematic.
Never found 1.75 mm ID ptfe.
I use the idea of Mike "What is Mike Making Now" see You tube "The best way of welding or splicing filament" for several month know. Sunlu had made a practical solutionof his idea.
Pre-Sale already sold out. Its about $40 USD.
The sold out is a placeholder. The pre-sale starts July 14.
@@FigureFeedback Well that's just lazy of the web team.
Thanks for the review, can you try TPU?
I guess we will need boxes of spare spilt PTFE tubes from SUNLU?
How about the problem of rewinding the connected spool on to the other spool. If not wound properly then the filament may overlap itself and break when printing a job.
I wouldn't consider that a problem any more than a screw needing to be turned with a screwdriver
Definitely adding this to the list of tools I need. My only question is, will they be selling the tubes separately? I know I'll need more.
I was thinking about this only yesterday. I'm a bit slow 😂
Hallo,
bei allen Komenraren finde ich nur ein Thema wichtig: wenn ich PETG verschweiße, reicht
dann die Temperatur in dem Gerät.
Ich finde die Lösung von sunlu super.
Gruß Klaus
The little sleeve - could you just reuse repeatedly or does the filament create a little flashing type effect?
I use the tiny bits for my son's 3D pen. Are you planning on showing the difference between this and DIY ones?
Nice demo! I’d be in for one, but what to the little plastic tubes cost for refills?
Thanks for the review 🙏
That consumable plastic tube is a big drawback for me… I think for a commercially made product it should be possible to make 2 metal parts that fit together with enough precision so that plastic consumable part isn’t needed… but this product is nonetheless a step in the right direction.
