ABS prints perfectly, PLA won't even load

Recommended Posts


I'm working with an Ultimaker 2+ and it looks like I had a blockage in the nozzle which I tried fixing using the atomic method. Now I can load ABS filament and make perfect high resolution prints, but I can't get PLA to load or go through the nozzle. Does this mean it's still clogged? Obviously it's related to the temperature the filaments are set at, I'm just not sure what the issue is exactly when the ABS loads fine and gives me nice prints. Any suggestions?

Try cutting the end of the PLA filament to a point using two angled cuts with a wire cutter.  I'm guessing it's just getting hung up at the transition to the teflon or the transition from teflon to block. that happens to me all the time if I don't cut the tip to a point.

I would agree with GR5 on this.  I have a UM2+ too and never had this problem as such.  

If the above solution doesn't work I'd heat the nozzle to about 215 at the most and manually push it through. I might be that the nozzle isn't hot enough to melt the remaining ABS.  (unlikely but who knows)

or just load it as ABS and once pushed though change the material type.

    • "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.
