Colorfabb nGen LUX Diamond Black, failed prints

Recommended Posts

Hi everybody.

I have been trying to print "something" with Colorfabb nGen LUX Diamond Black in my UM2+ without much success so far.

I have tried several nozzle temperatures, from 210 to 240, and several  printing speeds and layer height.


The major problem I see are large spots here and there, poor adhesion and, apparently, not enough filament feed.

The feeder on the back on the printer jumps often when using this filament. I have checked it and looks fine (it does not jump with other filaments).

The filament is oily to the touch, so I believe this might be the reason for feeder jumping.  


Has anyone tried this filament with success on UM2/UM2+?  If so, which setting have you used?

I'm the same as Didier, I have printed with this filament and used the recommended colorFabb settings without any real problems. My main issue was ensuring that the material didn't warp on the buildplate, so I had to make sure I had a good, even adhesive layer on the glass before printing with it.

An example of the parts that I printed with it are attached.

If you suspect it could be due to the oiliness of the material then make sure first that the knurled drive wheel in the feeder is clean and free from any clogging, and maybe also play with increasing the pressure of this wheel onto the filament using the adjuster screw on the feeder.

    • "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.
