Sunlu filament fuser/connector. Gadget, tool or gimmick?

I have to say this caught my eye but is it useful or one of those things that seems like a clever idea in search of a problem to solve?:wink:

The lost me at the consumables. Apparently one need these custom use-once PTFE sleeves. That is a deal breaker.

And of course, in what I have started to assume is just business as usual for the chinese, they falsely advertise a list price that nobody ever paid and list a discount before the product has already shipped.

Then to add to that lunacy, they advertise that they are out of stock for a product they havenā€™t even built yet.

Doesnā€™t ā€œsold outā€ imply that t here was a ā€œfirst saleā€? Then riddle me this, how can you be sold out of a product you never shipped before?

This whole thing just reeks of being a scam.

There is also no info on a price for sleeves.

Good demonstration on how to spread 60 seconds worth of information over 10 minutes.

I just watched this.

I guess if you want to take the time to figure out how many meters for each layer change (or grams) it would be something. Nothing stopping you from getting your hands on the sleves and a lighter or other heat source.

Given you can use up your spools with an AMS I donā€™t think itā€™s that useful. If you donā€™t have one I guess that pushes the needle a little, but again, the sleeve and a heat sourceā€¦

Iā€™ve been joining mine with a heat gun and some PTFE tube that is reasonably tight to the filament, saw someone do it on YouTube and gave it a go. Works pretty good and Iā€™ve been using the same pice of tube for about a year. Just cut splice on each pice and push almost together in the PTFE then heat with the gun and press together, also works without the splice. Thinking of designing a little jig to make it easier but keep getting carried away with other projectsšŸ˜‚.

Another thing in this video which looks like users have missedā€¦
Sunlu now has a new spool that fits the AMS Lite.

If you have an AMS you donā€™t need a filament splicer, just load your end bits onto the 4 filament holders and have the AMS do fail over so that when one filament runs out the next is loaded.
