I always wondered how I was going to stop wasting my filaments on spools with little filament left on them. This has answered my question thanks for sharing.
Its not a bad price compared to the previous existing solutions, I was thinking about making one of those DIY filament joiners to get some use out of all the tiny leftover filament spools I have sitting around but this looks like a easier way to do it than hacking something together I think the only complaint I can think of is that it uses a barrel jack to standard USB, in 2024 these things should just be USB C, with USB C PD they could of drawn more power too instead of being limited to 5v 2a, that could of raised the price a bit but honestly I'd be fine with the tradeoff
Great video Igor! The only question now is: what on earth can I do in mine that will be different? 😂😂😂 I think it is a great little device to have at hand when you need.
Trying to make things go wrong, maybe: - in an extruder with a very narrow filament path - a multi material system that pushes and pull the filament - a janky reverse-bowden where the filament gets bent pretty heavily, to see if it breaks. That's questions I have 😛
Exactly! 😀 Imagine getting a pack of complimentary gummy Benchys instead of (the usual) bears the next time you open that box from Prusa. If they made a deal with Haribo, it would be epic! ✌️😎
used alot of sunlu filament the last 3 months . very happy with it the pla and pteg print just as good as bambu. the best part is the fact i can get it next day from amazon. bad part is theyre always out of stock alot of the time LOL
I was put off by the single use tubes, but being able to re-use the tubes is good, although maybe not very practical if joining long lengths. The price in UK pounds is more attractive than the dollar price too, so I've ordered one.
Can we get the slicers to create a "color length cut list" to make a multi-color print using this? With pre-cut lengths of filament of the correct lengths? EDIT: Should be easy to make a script for this... Just sum all extrusion commands between each M600 or T0/T1/T2 command... EDIT2: On second thought. A completely unreasonable amount of splicing to be done for a normal multi-color print...
Something like this might be useful for creating extra large spools. You'd need to find a way to wind them, but just take two 2kg rolls and connect the ends. Mainly for very large single prints though
Can you reuse the cut tube? No reviewers have done that. I’m thinking it may cause flashing if it not aligned well. As it would allow spools to be joined rather than just remnant pieces. Is there a way of investing the lap more like a scarf joint l….
Many filaments don't bond together even when heated. It is the same reason why people like to use PLA as zero clearance supports for PETG prints and vice versa.
I've manually spliced rolls together when I see one is running out. I simply heated one end with a lighter and touched it to the other end and sanded them to remove the blob. It worked fine but it's probably not perfect because the diameter might have changed. I can see how this would be cleaner. Too bad they can't make it not use the teflon tubes.
I saw another review where the welded filament was getting stuck whilst printing, I suspect he wasn't mitring the ends with a 45° angle as the joint was fat, I just use my AMS and set it to continue with another spool when it runs out.
I was hoping, that the welder would not need the tube. To remove the tube I need one side open. However sometimes I would want to weld the filaments during print time. Well even most of the times. Pausing for filament change may introduce artifacts on print, so I would like to weld on the go.
Great review! Ideally the Teflon would be in the press but I suspect they tried that and reverted to the supplied tubes. Did you measure the joint thickness, in a (tight) Bowden arrangement the joint can get stuck, or even in the extruder if the joint is too thick.
Some time ago I watched a video on youtube about this procedure by someone (unfortunately can't remember the channel atm) who also connects nylon fishing line together in the same way - of course without a dedicated device, just a heat source and a teflon tube. His suggestion was to cut the filament at a 90 degree angle (ie. straight, flat end) as it is easier to hold and push together during heating than two ends cut at 45 degree angles. Did you try this, and if so, is it easier and does it affect the strength of the join?
But is the diameter of the weld still exactly 1.75mm? Thats my problem, i cant have wide filament areas cause it wont fit through capricorn bowden tubes
Oh god Sunlu. Its USB powered. Just put a USB port on the back. We get a stupid barrel jack to usb cable that will just get lost instead of using any USB cable that we already have.
With a barrel jack you can use any 5V 2A PSU instead of just a USB one. There are nice little power adapters that come with changeable plugs that cost very little and are very handy for powering many types of little devices. I'm sure most makers have at least one around for occasional use.
I'm still watching but about zero waste, I'm interested by the product but I find problematic that each connection would require using and wasting a PTFE tube. Which is a forever chemical, not at all what you want to be used as consumable ☹ Looking forward to the rest of the video then.
I watched every single video on the internet about this product. Your video is by far the best of them all. Thank you so much
Finally! I watched 5 other reviews before yours, and you were the first one to try to reuse the tubes, and successfully.
I just did things that I was curious about

Buy a Bambu printer with AMS. Voron with ERCF will still waste some filament. For my Voron around 1m.
@@Todestelzer Even a tool like this is spending a lot for a minor problem, but recommending a whole printer and MMU is just…ridiculous.
Just get a filament runout sensor for whatever printer you already have.
Fantastic video! I've been disappointed in many other's videos, I knew I could trust you to provide honest, good feedback on the product.

Try to play with the slicer, to have color changes on equal haights 😀
Trying to make things go wrong, maybe:
- in an extruder with a very narrow filament path
- a multi material system that pushes and pull the filament
- a janky reverse-bowden where the filament gets bent pretty heavily, to see if it breaks.
That's questions I have 😛
New video quality looks great. Always great content that gets right to the point and not dragged out to 10 mins. Thank you for the tests.
Currently my favorite channel on RUclips.
That's the tastiest, candy-looking 🍬 Benchy I've ever seen. 😋. If HARIBO made these, I'd buy them!
I think you just gave a very good idea for factories including gifts for product. Or some kind of exhibition/fare stuff
Exactly! 😀 Imagine getting a pack of complimentary gummy Benchys instead of (the usual) bears the next time you open that box from Prusa. If they made a deal with Haribo, it would be epic! ✌️😎
@@newstream2000 and there are plenty iconic models as well aside benchy. Xyz cube, dog, cat, the owl, temp tower, etc...

I currently do similar by hand with a Teflon tube and a heat gun. But that is pretty slick. Might consider it if the quality is good when released.
The splicer is always an option. But what really caught my eye in the video was that Sunlu has changed their spools to fit the AMS Lite.
This is one of those things I don't really need but definitely want just to mess around with. I'll probably grab one if it goes on sale.
I expected higher max temperature, would be useful for my recycled PET project
Need that! Preordered with your link! This will be fun.... hopefully.... when it will be shipped.
super cool! very well might have to pick one of these up.
I was put off by the single use tubes, but being able to re-use the tubes is good, although maybe not very practical if joining long lengths. The price in UK pounds is more attractive than the dollar price too, so I've ordered one.
This would certainly be better than my printed welding solution, however, this is way too expensive.😳

Could you do multicolor by swapping color at precise points in the filament?
Something like this might be useful for creating extra large spools. You'd need to find a way to wind them, but just take two 2kg rolls and connect the ends. Mainly for very large single prints though
But you can do this only if you unroll/roll them.
Can you reuse the cut tube? No reviewers have done that.
I’m thinking it may cause flashing if it not aligned well. As it would allow spools to be joined rather than just remnant pieces.
Is there a way of investing the lap more like a scarf joint l….
Would please try different combinations like PC vs ABS or TPU vs PETG for example?

It worked fine but it's probably not perfect because the diameter might have changed. I can see how this would be cleaner. Too bad they can't make it not use the teflon tubes.
They could, but in that case, some water cooling should be integrated.
I saw another review where the welded filament was getting stuck whilst printing, I suspect he wasn't mitring the ends with a 45° angle as the joint was fat, I just use my AMS and set it to continue with another spool when it runs out.
Do you remember which channel? I want to see it. Thx
👍 thanks
seems useful

There's a cutter that slices the teflon tube open from the side. Did you not watch the video?
I won't buy because it needs a teflon tube. I am for filament joiners, just not ones designed around constantly selling garbage (aka consumables)
Great review! Ideally the Teflon would be in the press but I suspect they tried that and reverted to the supplied tubes. Did you measure the joint thickness, in a (tight) Bowden arrangement the joint can get stuck, or even in the extruder if the joint is too thick.
I didn't measure it. But until the tube is in good shape, it's fine.
Did u try reusing the cut ptfe tube? Seems to me they can be used even when cut if heater block has round shape.

love the channel!
why do they need the ptfe? is there no way to go around the problem? maybe another design?
Explained at the end of video. Without tube, we would need some quick cooling system
zero waste but the waste is one of the most dangerous materials (forever chemicals)
This needs small _arms_ to hold and tension the filaments before, during and after heating 😅
I ordered one last week but it won't arrive until end of september 😥😥
Oh god Sunlu. Its USB powered. Just put a USB port on the back. We get a stupid barrel jack to usb cable that will just get lost instead of using any USB cable that we already have.
With a barrel jack you can use any 5V 2A PSU instead of just a USB one. There are nice little power adapters that come with changeable plugs that cost very little and are very handy for powering many types of little devices. I'm sure most makers have at least one around for occasional use.
You have my vote for usb-c plug!
Shoot I already preordered using another creator’s link, I would have rather ordered using yours. 😢
what I don't like is having to use the little sleeves :(
Why is no one testing tpu?
Proprietary USB cable - WHY? No go for me...
I'm still watching but about zero waste, I'm interested by the product but I find problematic that each connection would require using and wasting a PTFE tube.

Well, it's nice to see that the PTFE tube can be re-used many times! I might get this.
35$ for a resistor lol
I would buy it if it didn't do the the same thing as a lighter, but actually pressed 2 halves together and then used active cooling to cool it again
