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.
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.
