[UM3] Extrusion issues with 3dSolex print core

Recommended Posts

Hi there!

I just ordered a 3D Solex hardcore print core from gr5, and I have been having some issues. I've been trying to use the .8 mm nozzle and receiving issues with feeding material through it. When I start a print the filament just can't make it through the nozzle, and ends up getting ground away by the feeder.

Print settings:

.8 mm nozzle

.76 mm extrusion width

PLA

1.10 extrusion multiplier

.3 mm layer height

3 shells

4 skirt outlines

25% infill

60 C bed

205 C nozzle

cooling fan on

2400 mm/min print speed

Any ideas as to why this is happening? This is my first time printing with anything but a .4mm nozzle, so any help is appreciated. Thanks :)

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      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.
