Does this really work?? Sunlu Filament Connector

Testing out the new Sunlu Filament connector to see if this will actually allow you to more easily connect all of those near empty rolls of filament you have laying around

I didnt see any other creators pushing them together. Most also did an angle cut.

[entilzhar]

of all the products on the market this has to be by far the best option, sorry Jessy but on this one you didnt do your homework very well evryone knows that you always cut filament at 45 degrees, also shout out to Nikkoindustries for the dog, still gonna watch your vids, love you dude

I've been using this same method for about a year now, using silicone tubing and a soldering iron to heat the connection. I learned it from another video on YT (What is Mike Making Now). It is the only method that I have found that is easy, inexpensive and most of all reliable. I'll just keep on using my soldering iron instead of spending money a device that does the same thing.

I just take my partial rolls and put them in my AMS and tell the AMS that they are all the same colors and it just autofills when one empties out. Easy peasy no welding or respooling….

[buendiasolutions]

I bought it and just received it. What helps welding the two rolls is having one stacked on top of the other so theyre angles follow the natural curve, then you insert it into the sleeve and then the machine.

Finally! I can use up all my filament scraps I’ve been saving since 2012 😂

[matthiasnott]

Tried it first time last night, with the help of this video, thanks for that. Worked immediately. Great little gadget.

Aurora Tech did a review of this device that shows combining two partial spools and then she also made a large print using multiple connections. It does seem to take a little finesse to get it working right, but it does seem to work. She also tested it using a number of different types of filament to see how well it worked. She was very thorough.
Something related to 3D printing that takes a little practice to get it to work right? Unthinkable!

[Noxpai]

from what ive seen most cut it at a 45 and push it together while its in the heating system still before popping it out but looks like a cool machine for small scraps

[greentea]

I'd try cutting the filament at an angle at both ends, so you would have a larger surface/contact point on both spools. Look up images of "splicing plants together" if you don't get what I mean

[FigureFeedback]

Thanks for the shoutout, Uncle Jessy!

I've been doing this - by hand - for years, never had an issue, I just join two clean ends with a small butane torch (a lighter would probably work) and then clean the join up with a scalpel.

[tom_foolery]

I've been using it, and yes there is a learning curve, but it works great once you get it down. It takes a little finesse to keep the weld at a diameter that will fit in a Teflon tube. I just turned a bunch of partial rolls into a single roll with it last night. If I'm doing multiple partial rolls, I just slide their connector on down while re-spooling it. I also have a Teflon tube for the filament to go through to ensure that the weld knot slides through fine.

"Lowering the temperature down to 170 seemed to work best"
That was the default temperature and you raised it up before you started using it so I think that's user error

[chrisjoyner]

I would love a whole video on re-spooling techniques and gear.

Two jigs could significantly improve the filament joining process. A trimming jig would ensure clean, straight cuts for a seamless connection between the two pieces. Additionally, a guiding jig would maintain filament alignment during the melting process, preventing warping and inconsistencies.

[digiscream]

I always thought one of these would be great, but...my P1S doesn't have a problem recovering from running out of filament. I guess the bonus of something like this is that you don't really have to be present, but I'm paranoid about printing while out of the house anyway after my Neptune 4 decided to start itself on the journey to combustion.

[greedyd]

I've used this Jessy and done a review on my channel greedy 3D you've got a cuti it at a 45 degree angle give it a Gentle push when it's inside and let it cool after I've got to be honest I've had some fantastic results with it good idea regarding the responding too😁

[The_Orbus]

It takes a little babysitting but iv found that Bambu printers are really good at detecting runout, pausing and resuming prints.
If you dont need something to be done overnight and have the time to just check on it every hour or so iv fount it pretty reliable to just reload it and resume prints when it runs out.

[pomzmetaldetecting]

Got my sunlu connector yesterday I never read any instructions as it’s straight forward, had one failed join as it moved once heated. Never applied any pressure and so far all looks good
