My problem with filament run-out sensors is that I have to be very quick to replace the spool. If you delay, there is a noticeable artifact on at the layer where the run-out happened. May save me from some print anxiety on a large print where I'm not sure the spool is big enough!
I teach 3D technology at a small school and we always end up with lots of left over spools with tiny bits of filaments on them. With this little machine we might be able to fuse those filaments together instead of throwing them away.
pretty much the missing link when it comes to making your own bottle based filaments is a solid reliable way to splice the pieces together. I can see this being quite useful for PET filament.
@@Coolfwip I've been using the PTFE tubing wrapped in a pen spring method with a lighter. You still end up having to sand the material down as it ends up bigger than 1.75
If you have a 1/3 roll and half roll yes cutting would be easy way? after looking at this the 1/3 roll will you would want to spool in the half roll right? so if some one came up with a winder where you could clamp the tube in the device to hold the tube in place then spool I would think you can use the same tube over and over??
as someone with multiple low spools this looks like it will be great to turn them into one usable spool as i have learned that multi color printing with low spools tends to jam the P1 ams from time to time when the end of the filament ends up between the sensor and the first stage feeder and cant retract for the color change
I already ordered one and I see defects where the print stops and starts back after loading more filament after I run out. Even on my Bambu P1S with AMS. I print things to sell and use the entire roll almost but have lots of rolls with 10-15g each. I'd like to consolidate all them to a roll and use that roll for odds and ends prints. Then I won't have all these partial rolls laying around either.
It could be nifty for making custom filament color blends, kind of like you did with the gray and orange. I might grab one to mess with when it goes on sale.
Yeah I'd be curious to see some prints with shorter sections of filament fused together to get a blended color look. Just takes a while to make the connections and depending on the size of your print it could take ages.
I bought one. I will definitely use it. I print almost every day and I fill the large beds of my printers. There has been more than one occasion where I would need to open a new spool knowing that other spools wouldnt have enough filament to finish while I'm at work or off to bed. Yes the run out sensors would pause the prints but they would most likely sit idle for hours till I could change out spools.
Great video very to the point, I bought one and have to say over time I have a lot of spools with just a bit of filament left which I keep for a while and the just throw away because it is not enough to make any prints ...now I can just make a fun spool with all my bits of filament that I have left and not throw it away.... 👍🏼
For $100+ Sunlu should include a brick. This device doesn't save much time compared to the far cheaper filament welders, like Hexagon, which costs about $40 on Amazon. Plus, Sunlu's device can't weld/connect all filaments like most of the inexpensive models. I'll pass on this. Thanks for the video.
I always end up with a small section of extra filament at the end . I might pre order one since it’s cheap. I usually have TPU I need to fuse together often.
All of my printers have runout sensors so no huge need for it. BUT, if you are printing something in vase mode, theeeeeen it’s useful. If your spool doesn’t run out then you don’t get a blob in your vase mode print where it pauses and restarts. That’s what happens on my FF adventurer 5M at least 😢
Yep if you have runout sensor you unlikely will have something you can connect. But resume often create some artifacts which may be undesirable. Also I saw DIY tools which done everything automatically, heating, wielding, pushing, cooling. And the main problem of those tools how to take it off without cutting filament again = ) I use PTFE tube and a lighter. Just left it on the spool. I take if off later when it prints over that place the tube stops at the filament input.
i have a lot of filaments that are brittle and broke off, i suspect that they’re wet. So this device might come in handy to splice them together. Although i don’t know if i wanna spend 30$ for that..
your telling me you don't have tones of almost empty spools that are not enough for a single print? i would love to have this to make one large spool so i can just use it for making test prints.
No I just let the printer detect when the spool is empty and load a new spool of the same colour after it. Or enable auto spool change in the ams and it does it for me.
I have already ordered one for me. Even my printer has filament runout sensor, it almost always leave noticeable mark on some of my models where filament was exchanged. so i really hope it will help in such cases.
Its at 100€ at the moment, i think this is a device that should cost about 10€ or maybe 20€. Hopefully it will get in this region soon. I think this is a very good product.
You could use this to automate color changes on prints your wanting multi color and don't have an AMS. In Orca and Bambu Studio after you slice a multi color print it tells you the length and weight of each filament used.
Yeah I almost included that method as part of the video. You’d want to print some sort of helping hand or jig cause it’s a bit awkward to hold the filaments together and heat with a lighter at the same time.
Don't know if or where it fits in? If you have a 3d printer you have many spools of filament that are not enough for a project. Hence the need. Just use a rewind station, very easy.
I have ordered one just to connect all the end off spools I have. Not enough filament for a print but too much to just throw away. And besides its about the same price of a spool of PLA so not too expensive.
Cool, I've always considered trying to make a DIY filament joiner so it's cool to see how a manufactured one works! It's a bit steep at the moment, but hopefully it leads to innovation and prices come down. I wonder if a cut silicone sleeve would still work okay, as that part of it being consumable seems like it could get annoying, and cutting it seems like the only way to do it unless you're joining super short sections as you mention. Still, if I had one, I'd probably just do something dumb like estimate lengths needed and try to get a multicolor print all on the same spool lol. Thanks for the video!
@sorenac $40 is still not quite my ideal price point, so the fact it's $100 USD puts it far out of reach. ETA: I've just realized the above link is to bundles only and not the machine itself, but it's still too niche a use case for myself and would be more a toy than a tool.
I got one... preordered rather, I have been printing for a couple years, and I have an obscene amount of rolls with enough to keep, but not for a print, so I can definitely use it, after the initial bonding, probably not as much, but I guess at least I'll have it on hand, I dont care for the fact they did make it plug in, and that they didn't include a power brick... thats annoying, in that MOST of us just have a phone power brick that won't work... overall for the preorder price point, I think it's worth it.
Im going to try an experiment with it. Im going to buy a big mixed color bag of 3D pen filament and make a radical color small spool then print something with it.....Should be cool
For me the consumable is the deal breaker. I was very interested because the manual methods are...unreliable at best. However the tiny amount of filament this would save me just doesn't justify the cost. Neat idea, poor execution.
I dont think a proper use case is fusing ends of filament from spools that are running out. Like you said, if your printer has a run out sensor you can just swap spools, but also the amount of filament you have to fuse together to actually break even on this $50 abomination is obsurd
I got one specifically to fuse together almost empty spools into fuller spools again, and while my printer has a runout sensor that's just another potential failure point I can avoid, also I use it to make interesting color combinations
And thus balance is maintained in the universe... On shorter sections you can just slide it off and reuse it but on larger sections it is a consumable. At least on the larger sections the ratio of waste to saved plastic is a lot better.
I run through probably 150-200kg a year... You telling me it doesn't come with a power supply almost makes it not worth it. That's fucking ridiculous tbh.
it's a gimmick that would be kind of interesting if the price was somewhere around 20€$. But at this price level, it's completely uninteresting and not yet fully developed.
Yoooooo this fits in for the idiot users who were like "im going to save a dollar and buy spolless " but then they create a bunch of knots in the front and back of the filament! I need to git gud
@@3DPrintStuff especially when you're smart enough to know you need to wait for the right tool to finish printing (spool and spool winder). I really thought I could just slide the roll to an old spool. :( Learned the hard way

THREE charger examples in was two too many for me and I'm gone. BTW - putting it back in the box so you can show us you taking it out again is also pretty strange. It's a filament connector; it connexcts filament. So how well does it work? Get to it! I hope that's helpful feedback.

@@enosunimat a school? Could be a fire hazard in the eyes of insurances and potentially put the teacher in lots of trouble.
You can take the spools outdoors and wield them there, then return back to class. = ))

With my AMS breaking filaments sometimes, I will buy this! I've got so many pieces of filament I could make a spool haha
Thanks for the discover
I would definitely use this to do the same sort of thing that you did with your Benchy example!!
Def has a use for me:
No runout sensor.
Bowden not Direct drive.
Fusing the filament maintains retraction.

I’m new to this, can’t you feed new filament behind the old and keep a little pressure till
it catches.
I guess you could do that but that’s a lot of babysitting your printer which will get old really fast.

Makes sense. Are you going to unspool the filament that is on the printer, fuse the end, respool onto the new spool?

good for doing filament changes on the fly. with one of my printers, it's a royal PIA, often dropping an X offset on the print, way too often

In my experience brittle filaments aren't worth holding onto... just create more problems than they're worth.
Does it work with PETG? I can see a use case for people making their own filament from 2L bottles.
