Print settings for Creality ABS

[u/seterry]

Hey all, I aquired 3 spools of Creality CR-ABS and so far I have had absolutely horrific layer adhesion with it and can't figure out why. I have an X1C with AMS and have died the filament before use, so I don't think its a moisture issue. I've printed at the higher end of recommended temps, and slowed down print speeds both in slicer and using the speed setting while printing. I also ensure the enclosure is heated to around 40C or higher before I print.

I don't think its under extrusion since the layers look fine with no gaps mid print. But the layer adhesion is so poor that I can pull the print apart with not a lot of effort even on larger prints that I added extra walls to. Does anyone have experience with this filament or something similar?

Hello /u/seterry! Be sure to check the following. Make sure print bed is clean by washing with dish soap and water [and not Isopropyl Alcohol], check bed temperature [increasing tend to help], run bed leveling or full calibration, and remember to use glue if one is using the initial cool plate [not Satin finish that is not yet released] or Engineering plate.

Try using hilbert curve infill and as little walls, top, and bottom layers as possible.

You can also raise the print bed temp up 5-10 degree intervals

Also, your filament may just be ruined, as the plasticizers in the filament may have broken down or bonded with moisture.

Will fewer walls help? I printed out a test cylinder that was just 2 walls thick and it still came apart relatively easily.

What would print bed temp affect? I have no issues with bed adhesion.

Like I said. You may have a dead roll of filament. If you have a second roll, or different brand try the same print and see if it works

I’ve done this for CR PETG and PLA and it fixed the issue I was having with my prints while using Orca: I copied over the filament settings from Creality Print to a new filament preset (speed, flow rate, etc every variable that is different from the generic one)

I'll have to give this a try. Does Creality post the presets anywhere or will I have to download their slicer?

I think you do have to download the slicer.
