Black ABS

[Geoff]

Ordered some black ABS and having a really tough time trying to figure out the right settings to print with. I keep getting goopy/sloppy prints. I've played with extruder temps from 226 down to 200, BP temps from 110 to 100, I keep my feedrate at 50 and tool feed at 80.

Any thoughts? Bad ABS?

I've done much better with white ABS and I've heard that was the tricky one to deal with....

Also I've noticed at lower extruder temps but even with a 110 degree BP the edge curl is insane. Currently using masking tape instead of kapton for the build plate coverage. The kapton had some air bubbles in it from the factory.

Yes, had the same problems. The black I got with my printer was HIPS ABS dissolvable, which printed.. sort of ok. It didn't like high resolutions, otherwise it printed messy.

The curling is pretty common with black for some reason with me too, so what I ended up doing was OVER heating the bed, like 112c.. which did seem to help.

Then I got some cheap black ABS from Flashforge. Wow is this stuff Bad!!!! Flashforge white ABS is OK! but their black I will never buy again, no matter how you try it prints like stringy black crap.. I hate it. Full of particles and crap.. such a waste of plastic. I have a whole roll of it. I can't even use it for quick test prints it is that bad. Then I tried the guys in New Zealand, the UP Plus and UP Mini guys, nope.. their black is just as bad. I had a really really bad run with black.

Then I Stumbled across cncbilby on ebay, so far they are winning. No, it doesn't print as well as white, but this is the first black that prints normally, or at least like a coloured filament. Prints at 230c and 110c hotbed and yeah, isn't all that bad actually for a $36 roll.
The only thing is the spools are the big type, as in tall, not short and fat so while the fit fine on the flashforge, they tend to want to slip back after a while, easy to stop with a roll of tape or similar.

Yep, this is flashforge black. I feel better now that I know its not all me. I may try the ebay guy! Thanks for the tip for sure.
