Print Parameters - COEX ABS

COEX ABS print settings

Print COEX ABS with a 245–265°C nozzle, a 90–110°C bed and an enclosure, with the fan at 0–30% (off for the first layer), and dry it at 80°C for 4–6 hours.

These are COEX 3D's recommended starting settings, made to match the COEX 3D filament settings tables for every filament we make in Green Bay, Wisconsin. Treat each value as a starting point and adjust it for your printer.

1. Material notes

  • Keep filament dry: store it sealed, and dry it again only after the spool has been exposed to air
  • Dry an opened spool at 80°C for 4–6 hours
  • An enclosure is required
  • Use a Z-offset slightly higher than for PLA (+0.05mm)
  • Enable "Avoid crossing perimeters" to reduce stringing
  • Consider using the "Wipe while retract" option
  • Enable "Slow down for small perimeters"
  • Print outer walls slower for better quality
  • Use a minimum layer time of 30 seconds for small parts
  • Consider using "Extra Prime Amount" after retraction

2. Temperature settings

Nozzle temperature: 245–265°C

Bed temperature: 90–110°C

  • Wash the bed often for good adhesion: use dish soap and rinse thoroughly to remove oils
  • Bed adhesion: use WELD3D, ABS slurry or Kapton tape
  • Use a brim for tall or large prints
  • Keep the ambient temperature stable

Top/bottom 60% 100.00 mm/s
First layer 30% 50.00 mm/s

0.6mm nozzle (max volumetric speed 31.5 mm³/s)

5. Retraction settings

Important: Set travel speed to the maximum your machine allows (200–500mm/s). Faster moves give the filament less time to ooze, which reduces stringing.

COEX ABS retraction by nozzle size
Nozzle Distance Speed Z-hop
0.4mm 1.0–1.5mm 40mm/s 0.2mm
0.6mm 1.0–1.5mm 40mm/s 0.2mm
0.8mm 1.0–1.5mm 40mm/s 0.2mm
1.0mm 1.0–1.5mm 40mm/s 0.2mm

6. Cooling settings

Cooling configuration:

  • First layer: 0% (fan off)
  • General printing: 0–30% fan speed
  • Bridges and overhangs: up to 30% fan speed
  • Layers under 15 seconds: up to 30% fan speed

7. Troubleshooting

COEX ABS troubleshooting
Problem Solution
Irregular extrusion
  1. Dry the filament
  2. Check the extruder
  3. Reduce speed
Poor adhesion
  1. Dry the filament
  2. Use an adhesive
  3. Adjust the first layer
Stringing
  1. Dry the filament
  2. Adjust retraction
  3. Increase travel speed
  4. Check temperature

Please note: These printing parameters are initial recommendations based on our experience. They may need adjustment for your specific 3D printer, environmental conditions and the geometry of the part you are printing. Use them as a starting point and fine-tune them for your needs.
