ABS printing issues.

[Saikedo]

To anyone who will stumble upon this post with similar issues.


It turned out that my major issue here was the bed temperature. Everyone keeps saying that we need high bed temps for ABS printing, well it turned out that there can be too much of good stuff . I was running my bed at 110C and also using a heated chamber and I was getting terrible warping issues. I lowered the bed temp to 95c and also started using Magigoo MO2016 for better adhesion and I even stopped using the chamber heating and the prints come out beautiful now, 0 warping. Ambient temperature inside the enclosure(closer to the print surface) is on average at 53c.
The horizontal lines that I was seeing turned out to be there for all materials, it`s just the specific ABS I was using was making them look much worse. I switched to Paramount 3D abs and things look much better now.


Take a look at the new results that I am getting now in the image below (Note, you might notice that I got a tiny bit of elephants foot going on on the bottom layers but that is because I run the nozzle a bit closer than it should be on purpose to get that nice uniform textured look on first layers. With this approach first layers look just fantastic, does not even look like 3d printed parts).

Glad you got it sorted.

My printer was from an early production run and as far as I know on mine there is no way to heat the chamber other than by the bed warming.
I run my bed at 95 and my nozzle at 245 for ASA and no fan on.

The one sure way I found to make warped prints was to open the door as soon as the print finishes, I now wait until everything is down to ambient temperature before opening the door.

Maybe you can check whether below is helpful to your ABS 3D Printing case:Use a heated print bed with a temperature of 110°C or higher13.Apply an adhesive layer on the print bed such as glue stick, hairspray, or ABS slurry34.Enclose your printer to maintain a stable temperature and prevent drafts14.Reduce your cooling fan speed or turn it off completely45.Increase your nozzle temperature to 230°C or higher15.Print at a lower speed and layer height to improve layer adhesion5.
