White CoexFlex™ 60D TPE

TPU-Like Flexibility, Faster Printing, Greater Strength

Experience flexible printing without the fuss. CoexFlex™ 60D TPE (TPC) delivers the same smooth, rubber-like performance you expect from TPU—but prints faster and with superior strength, heat, and chemical resistance.

With excellent layer adhesion and a soft 60D Shore hardness, it’s ideal for parts that need to flex, bend, and endure repeated use. From protective grips to seals and functional prototypes, CoexFlex™ 60D maintains durability where TPU can fall short.

Formulated from a Thermoplastic Copolyester Elastomer (TPC), it offers exceptional temperature and abrasion resistance while remaining easy to print on any TPU-capable setup.

Proudly made in the USA.

Technical Printing Guide - COEXFLEX 60D

1. Material Notes

  • Keep filament dry - store properly and dry before use
  • If needed, dry at 55°C for 4 hours or more
  • Preferably use a direct drive extruder
  • Print multiple parts sequentially to minimize stringing
  • Use maximum travel speed to minimize stringing

2. Temperature Settings

Bed Temperature: 25-85°C

Extruder Temperature: 205-225°C

3. Basic Parameters

Unlike rigid filaments, TPE stretches when extruded, producing thinner lines. The line width will be smaller than the nozzle diameter. To ensure proper bonding between vertical walls and perimeters

5. Retraction Settings

IMPORTANT: Set travel speed to the maximum your machine allows (200-500mm/s). Faster movements reduce filament oozing time, minimizing stringing.

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:

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

7. Troubleshooting Guide

 Problem Solution
Irregular extrusion

1. Dry the filament

2. Check extruder

3. Reduce speed
Poor adhesion

1. Dry the filament

2. Use adhesive

3. Adjust 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 depending on your specific 3D printer, environmental conditions, and the geometry of the part you are printing. Use these settings as a starting point and fine-tune them according to your specific needs.

5.4 Remark:In case of fire and/or explosion do not breathe fumes.

6. Accidental release measures

6.1 Personal precautions:Spilled material may cause a slipping Hazard.
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.
