Innofill and Ultimaker PLA filament snapping

Recommended Posts

I would like to amplify this query. Every so often, I have had filament snap around the entry to the feeder. Sometimes the cause will be clear, in that the filament has become tangled. On occasions, though, I get a sense that the friction involved in turning a full reel of filament may be enough to trigger a snap. I particularly feel this with the outer reels on UM3s - those which feed into Printcore 1.

 

I've recently had this happen with loose filament which hangs loosly round an empty reel. On a recent long print, I loaded 50 coils (say 40+ metres) of new PLA, taking great care to ensure that the coils would not get tangled. It snapped after using less than 10 of those coils. When I re-inserted the remaining 40 coils, the print ran totally smoothly, so tangling was not an issue.

 

I'm pretty sure I've never had a simple break like these when I've printed using 10-20 metres of loosely hanging filament, draped round a reel.

 

Is friction a serious issue when one is dealing with longer runs of filament?

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
