How about your filament path? Is there high resistance? The filament roll, is it hard to roll on your filament holder? How about reverse bowdens?

Is the extruder gear too tight or too loose?

I’m pretty sure it’s exactly that. Electric engines during takeoff and landing would also decrease noise pollution near humans.

Seriously, amazing piece of kit and pretty open and hackable at that.

Way fun to use.

Only downside: the reverse bowden tubes make printing with PLA annoying because it keeps breaking in the tubes if you leave it in there for a few days without printing.

The upside: it prints PETG just as well as PLA, so I just stopped using PLA alltogether.

I used to recommend the Bambulab A1 (Mini), because they are amazing, really cheap printers. But Bambulab in the meantime Bambulab is pulling an Apple in a very bad way, so can’t recommend them anymore.

I have a Snapmaker U1, a decidedly not-budget printer, but I can totally recommend that one for anyone who’s seriously into 3D printing. What an awesome machine!

I damaged my stock Snapmaker U1 build plate with a print of 2 layers TPU 85A topped with a solid PETG print.

TPU 85A only comes off the build plate because you can bend and peel it off. The PETG on top of it stopped me from doing that. It was a dumb idea.

You can absorb it via the skin too.

Look up the Oxygen Catastropy, also called Oxygen Holocaust.

That’s what happens if too much carbon is removed from the atmosphere and thus there’s too much oxygen in it.

The downside of that kind of stuff is that you need a balance. Scrub too much CO2 and it’s trouble again.
