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.
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
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.
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!
@@FigureFeedback 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!
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.
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 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 😊
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
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.
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!
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
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.
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.
@@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.
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 😆
It's very similar to a fusion splicer for fibre optics in the telecoms industry. What's needed is to print up a little 45 degree cutting jig so that you get perfect clean cuts on the ends before inserting into the splicer.
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.
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
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.
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
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.
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!
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.
Revised to 3 out of 5 stars. I guess at a $40 price point, its worth it. Just know what you're getting. I have been looking forward for mine to arrive. I ordered it shortly after this video hit RUclips. It arrived today. I had high hopes and wanted to give it good reviews. I have 3 reels of leftover PLA I wanted to join. My reason for the low rating is you really need two people to operate this correctly. The video shows 2 short pieces of filament. Without back pressure from a reel or a coil, the two short pieces stay where you put them. But in real (reel? ha!) life, you need two hands to keep the two pieces of filament together. But, you have to do with with just the right amount of force. Too little and pieces won't join. Too much and the filament will bulge and not fit in to the Bowden tube. This is why you need another person: If you're by yourself, with a thumb you can move the cover. But then you need both thumbs to push down with enough force to latch it. A second person really comes in handy to latch and unlatch the cover. I am by myself, so I have to figure this out the best way I can. When the unit beeps that its done (about 5 seconds), you can unlatch it with a thumb. But everything is still hot. The PLA will still move. The fused part needs to kept still while it cools. Pro-tip here: When it beeps to let you know its done fusing the pieces, with a thumb, hit the power button. Let the unit cool for about 2 or 3 minute before unlatching the fused PLA. The PLA should have enough time to cool and not distort when you removed it from the hot area. Also, be sure to let the fused joint cool before trying to cut the sleeve off. It took 5 or 6 fuse attempts to get a good fuse. Again, I wanted to give this higher marks, but I can't.
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?
It's a step in the right direction, filament on the roll gets very springy and trying to join the two ends together with the device is going to involve a lot of steady holding and waiting, but it should get the job done.
Good review. However, it would be nice to know what the power requirements are so we know what kind of power supply to buy (i.e. amperage draw and voltage range).
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.
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 ?
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.
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.
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!
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
It does look interesting but the idea of having to buy them tiny little connector pipes to use it is a bit of a issue. Is it some kinda heat shrink you remove after?
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.
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.
Very nice implementation! Are the little tube pieces just cut up PTFE tube? Have you tested the strength of the joint by bending and flexing it? I always had problems fusing stuff together because the joint would be weak and/or leave a larger diameter area where you had the sand it down. It seems those little tubes fix the bulging problem....
I've been wanting one of these for years! But now my Prusa printers have run-out detection, which will always prompt me to change the filament when one roll runs out. Do you think that feature makes this need for splicing obsolete?

Really like your channel Jeremy!

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.

theres other versions of this that are a couple years old that dont require those connector sleeves. they work just fine.
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.
