Topic: abs filament the doesnt flow

Has anyone had any abs filament that didn't flow as quickly as others? I have a new roll of octave abs and it doesn't do small areas or supports very well because it seems like it doesn't flow very well. How did you adapt your slic3r to this?

Re: abs filament the doesnt flow

two option I can think of:

Increase the extrusion multiplier (Filament Settings), or increase extrusion temperature, or better yet, a combination of the two.

To print or, 3D print, that is the question...

It is normal to have to make temperature changes and other tweaks per roll. This goes for the same brand and even the same color.

The normal at least for me process is any time I change rolls, I print a calibration cube or other object of known dimensions. That way I can see how it flows, what it's shrinkage factor is and other parameters. Then I make the necessary tweaks for that roll and print. Some store profiles for every roll they use but I have found that to be a lost cause as each roll is unique.

Printing since 2009 and still love it!

All too true. 

I used to be one of those that kept a spreadsheet with the brands and settings.  Eventually tossed it out the window and now I do just about the same as Carl,  run a calibration print and adjust accordingly for each roll.

Re: abs filament the doesnt flow

When you change colors frequently (as I do - nearly every day - sometimes multiple times in a day) the stored profiles are handy for a given, specific spool.

That said, yes, each spool - even same brand and color - will be different, and as such should be calibrated to match that particular spool.
