Running out of plastic.....

Recommended Posts

That's the best way to do it, yes. Although if you're careful (and depending on the firmware and feed mechanism), you may be able to pause the print, change the filament, and carry on.

In reality, it's a bit of a non-issue. Filament comes in massively long spools, and most prints use only a fraction of it. I've bought and sampled quite a lot of filament in my almost-two-years experience printing, but I don't think I've ever actually finished a full spool of anything.

You probably don't want to use the last few windings of filament on the spool to print anything critical. That last section is more problematic for feeding through the Bowden system, anyway. Basically, your best bet is to always make sure you have plenty of filament on the spool before you start the print. It's a coin flip whether you can keep the print going by sliding more filament in during the print and trying to pause the print is even less dependable. When a spool gets pretty low, I set it aside for printing tiny parts. That way, if I run out mid print, I haven't wasted much at all.

If I am in the room when it runs out, I just feed the next one.

but if I don't want to wait, I just melt the two together with a lighter, and file it down a bit, works perfect :)

And buying 2Kg spools also helps :)

On the UM2 it is quite easy to feed in the next material. On the UM-Original this can be a bit more tricky. But you'll have to be there at the right time.

The material estimate of Cura is actually quite accurate. It usually allows me to judge if there is enough material on a roll. But then again, I do have a bit of printing experience already.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
