Cheap, low-effort, perfect filament splicing method (toobnix.org)

Okay, this is an update of my first method using regular paper to splice filaments that I posted last week. It was okay, but it did require cleaning the splice because some paper stuck to it.

Somewhiteguy suggested in this comment that baking paper might yield better results. And boy! does it ever!

I've been thinking about trying this the entire week. Finally I got me a roll of the cheapest baking paper I could find at the supermarket while doing the groceries for the weekend and gave it a shot.

It is SO MUCH BETTER!

And here, just to prove it, I filmed myself doing a splice in real-time (sorry for the harsh light and the flickering, I filmed this under neon light in the lab).

Less than 3 minutes from start to finish if you ignore me fumbling with my cellphone to film this. No cleanup, perfect splice, and the roll of baking paper cost me a dollar and will last me a lifetime!

I genuinely thing this is the cleanest, cheapest, easiest splicing method that doesn't wastes bits of PTFE tubing at each splice.

And most importantly, your paper probably requires significantly less nasty chemicals used and disposed of in its production than PTFE.

PFTE, a.k.a. Teflon, is a forever pollutant in and of itself (despite the finished product being mostly inert), but the ingredients used in its production are seriously nasty stuff. Just using little chunks of it and throwing them away to merely stick bits of filament together is a monumentally stupid idea, and Sunlu ought to be ashamed of themselves for even proposing it. I'd rather freehand splices together with a lighter than do that.

Even better: you can reuse the baking paper if you don't overheat it 🙂

I like it. Cheap and easy.

Looks like a little bulge in the joint, so you'd have to be a little careful about how it feeds, but I think it would be pretty easy to check.

Also like how you don't need to completely unspool one side to make it work.

Most printers won't care much about diameter on feeding, although if you run your filament through a Bowden tube that's cruising really close to the specified diameter that may cause you some problems. The real effect will be that your extruder assumes the filament diameter is consistent, so if you're over or under you'll get an over- or underextrusion. I don't think there's enough length of off-spec filament created by this process for it to noticeably matter, though.

Our printer feeds fine with filaments bulging up to 2 mm. What it doesn't like is uneven transitions.

Yeah, I imagine if you had like a stair step in it that might give your extruder gears some trouble.

Epic follow up. We keep parchment paper on hand and I'll give this a go when I'm getting near the bottom of a row. This will be much easier than feeding the new role in mid print.

This is brilliant!
