Black CoexFlex™ 60D TPE

CoexFlex 60D is a thermoplastic copolyester elastomer (TPC). It flexes like TPU, but prints faster and has more strength, heat resistance and chemical resistance. 60D is the firmest grade in the CoexFlex line. Use it for parts that need to flex and bend repeatedly: grips, protective cases, seals, gaskets and functional prototypes.

Key properties

  • Rubber-like flex with strong layer adhesion
  • More heat, chemical and abrasion resistance than typical TPU
  • Prints on any TPU-capable setup

Recommended print settings

  • Hotend: 205–250°C
  • Bed: 25–85°C, heated bed recommended
  • Part cooling fan recommended
  • Build surfaces and adhesives: Magigoo, Magigoo Flex, painter's tape, glue stick, or PEI with a release agent. CoexFlex bonds very strongly to glass and smooth PEI.

Available CoexFlex hardnesses: 30D · 90A · 40D · 60D. See the full CoexFlex range.

CoexFlex 60D TPE print settings

Print CoexFlex 60D TPE with a 220–240°C nozzle, a 25–85°C bed and the fan at 0–40%, with no enclosure, and dry it at 50°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 50°C for 4–6 hours
  • No enclosure is needed
  • Preferably use a direct drive extruder
  • Print multiple parts one at a time (sequentially) to minimize stringing
  • Use maximum travel speed to minimize stringing

2. Temperature settings

Nozzle temperature: 220–240°C

Bed temperature: 25–85°C

  • Use a glue stick or hairspray as a release agent, or WELD3D. CoexFlex bonds very strongly to glass and smooth PEI, so a release agent protects both the print and the plate

3. Basic parameters

Unlike rigid filaments, TPE stretches as it is extruded and lays down thinner lines, so the line widths below are slightly smaller than the nozzle diameter. This keeps walls and perimeters properly bonded.

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.

CoexFlex 60D TPE retraction by nozzle size
Nozzle Distance Speed Z-hop
0.4mm 1.8–2.5mm 40mm/s 0.2mm
0.6mm 1.8–2.5mm 40mm/s 0.2mm
0.8mm 2.0–3.0mm 40mm/s 0.2mm
1.0mm 2.0–3.0mm 40mm/s 0.2mm

6. Cooling settings

Cooling configuration:

  • First layer: 0% (fan off)
  • General printing: 0% (fan off)
  • Force fan speed for overhangs and bridges: off
  • Layers under 20 seconds: 40% fan speed

7. Troubleshooting

CoexFlex 60D TPE 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.

6.2 Methods for cleaning up:Vacuum or sweep up material and place into a suitable disposal container.

7. Handling and storage

7.1 Handling:Avoid contact with molten polymer.
7.2 Storage:Protect against moisture. Store cool and keep packaging closed when not in use. Avoid sources of ignition.

8. Exposure controls/ personal protection

8.1 Technical safety measures:General mechanical ventilation is normally adequate but use local exhaust where necessary to maintain exposures below acceptable limits. Use local exhaust to completely remove vapors and fumes liberated during hot processing from the work area.
8.2 Personal safety equipment:Use adequate safety equipment, e.g. protective clothing, eye protection glasses, heat protection gloves. Additives in this product do not present a respiration hazard unless the product is ground to a powder of respirable size and the dust is inhaled. All dusts are potentially injurious to the respiratory tract if respirable particles are generated and inhaled. A respiratory protection program that meets country requirements must be followed whenever workplace conditions warrant respirator use. Consult the respirator manufacturer to determine the appropriate type of equipment for a given application. Observe respirator use limitations specified by the manufacturer. Consult the OSHA respiratory protection information located at 29CFR 1910.134. Use a positive pressure air supplied respirator if exposure levels are not known or there are any other circumstances where air purifying respirators may not provide adequate protection.
