What do you do with last piece of filament on spool?

Recommended Posts

I think that this issue deserves some comments from UM experts. I too have lots of spools with not enough material to print things I want. We should definetely research a way to weld filament tips so that the weld becomes good enough to survive going through the feeder.

I've seen people make filament splicers. It's basically just a metal block with a hole drilled through it, then split in half. Place the ends of two stumps of filament in the thing, close it, heat it up, push the stumps together, take out and let cool.

Personally I'm way too lazy for that though and toss it out or do test prints with it.

You don't need (and can't get) a FUSE - it was apparently a scam, in which I and many others never received anything for our money.

Instead, use the Change Filament feature of the UM2.

Start a print with the smaller amount, then "change" the filament to a new spool of the same stuff. Do this while it is printing fill, so it doesn't show on the outside of the piece.

You need only waste a piece of filament a little longer than the Bowden tube.

    • "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.
