Hi This thread started about ABS of which I have a little knowledge. Perhaps I can help, despite a student profile definition I am a scientist and development engineer of more than 50 years experience and back at the beginning of lockdown was asked by the scientific consultancy I am a member of to look into bring 3d printing in house to reduce the disruption caused by the delays of sending out 3d prints to a bureau. As a result we purchased a basic machine(a ender 3pro-sorry curious Aardvark)p and set up and controlled experiment as to what we could do with it. We wanted to be able to print in ABS and Nylon routinely.

As part of that we tried a very large number or build plate materials and adhesion aids - bat thats another story!! we also bought a range ABS filaments to try ( I know that is only possible when you have a company cheque book !) . In the case of ABS filaments we tried 3 filaments with a couple os standard models that we already had had made by SLS in nylon. We found that with a model with an area in contact with the bed plate of 53 x 53 mm and sharpish corners we had reliable printing with only one of the materials which was 3dfiloprints ABS X and that the reliable ( almost 100% success) with either Enders accessory Glass plate with printed on texture or Fufnol Whale Grade SRBF sheet sanded with 220 to remove the shiny surface both best with a thin layer of ABS juice.

print Settings

layer Ht 0.3 initial
Layer body 0.2
Build Temp 245
initial Temp 250
Build Plate 80
These temps used building onto a 1mm Tufnol Sheet clamped to the Creality glass bed (plain side)

Fan ON

Speed printing 70mm/s
initial 35mm/s
we use a skirt to start the extruder and work in a perspex enclosure with no additional Heating.

I hope that helps.
