I’ve had ABS filaments perform all over the place - some would curl like crazy, others end up super brittle, some tore their layers apart. This russian REC brand one is decent, are there other brands that you’ve found to be reliable?

The best(by so much it’s almost unbelievable) ABS I have is.
I went to the local plastic injection company.
Got natural ABS pellets.
Turned that into filament using… Forgot it’s name, if i remember I’ll update.

I never get bubbles, never laminates, and warping was much less an issue.
The finished prints look more like PLA.

The only downside is trying to make consistent filament at home.

@Andrew_Frahn do you remember the brand and type of ABS they gave you?

@Thomas_Sanladerer ​​ there was hundreds, without exaggeration. I don’t remember, he gave me the one he believed would have worked the best.
I would have to go back and ask.

He did the same with PP but I never got a success from it, is too thick, heat it up enough to extrude, and I destroy it.

@Andrew_Frahn oh brother dude you can’t leave us hanging here like that. No brand name, no filament extruder name, not even the name of your friend’s company! Hahaha

Filastruder!!!
Pretty sure that was it.
I got it from Danbar Plastics, but being a small country business, that probably won’t help much.
I will find out the plastic…

The big issue with ABS is that it’s made of 3 specific polymer compounds (acrylonitrile, butadiene & styrene), and that there isn’t really any fixed values for what percentage of each makes a plastic ABS. Wikipedia lists them as “15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene” but even those values aren’t set in stone. This leads to many different types of ABS plastics that can all have vastly different material properties.

@Stuart_Young plus modifiers - those alone allow for infinite combinations.

@Thomas_Sanladerer ​ is spot on, there are other ingredients to change its properties as required.

I’ve had good luck with the filament from ToyBuilderLabs. They call it Prototype Supply. For a while it looked like rebranded eSun media, which it might have just been eSun’s ABS, but they recently changed formulation and the new stuff looks good too

I’m a fan of the ABS from 3DXTech and Atomic.

It used to be more common to say what pellets were used to make the filament but it seems most brands are keeping that proprietary now.
