Natural CoexFlex™ 40D TPE

CoexFlex™ 40D TPE is our third most flexible filament in our CoexFlex™ product line. With great layer adhesion and soft nature, it can be used to create very durable and flexible prints. 60D can be referenced on the Shore Hardness scale. CoexFlex™ 40D TPE is a TPC (Thermoplastic Copolyester Elastomer), which exception temperature resistance, abrasion resistance, and tensile strength.

Our CoexFlex™ TPE/TPU lineup of filaments will give you the best results when you require a flexible 3D Printing Filament.  Proudly made in the USA.

Technical Printing Guide - COEXFLEX 40D

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 direct drive extruder
  • Print multiple parts sequentially to minimize stringing
  • Use maximum travel speed to minimize stringing

2. 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

Nozzle Layer Height Line Width Volumetric Speed Temperature
0.4mm 0.2mm 0.35mm 3.2 mm³/s 240°C
0.6mm 0.3mm 0.55mm 7.2 mm³/s 242°C
0.8mm 0.4mm 0.75mm 12.8 mm³/s 245°C
 1.0mm 0.5mm 0.95mm 20.0 mm³/s 248°C


3. Speed Settings

0.4mm Nozzle (Volumetric Speed: 3.2 mm³/s)

 Line Type Percentage Speed
External Perimeter 50% 22.85 mm/s
Internal Perimeters 75% 34.27 mm/s
Infill 100% 45.7 mm/s
Top/Bottom 60% 27.42 mm/s
First Layer 30% 13.71 mm/s

Infill 100% 42.11 mm/s
Top/Bottom 60% 25.26 mm/s
First Layer 30% 12.63 mm/s


4. 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 1.5-3.0mm 40mm/s 0.2mm
0.6mm 1.5-3.0mm 40mm/s 0.2mm
0.8mm 2.5-3.5mm 40mm/s 0.2mm
1.0mm 2.5-3.5mm 40mm/s 0.2mm

5. Temperature Settings

Bed Temperature: 25-85°C

Extruder Temperature: 205-225°C

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.

Tolerance: At Coex 3D, we use multi axis laser measuring heads to ensure a tolerance of ±.03mm.

Quality: All Coex 3D printer filament is manufactured in our Green Bay, WI production facility. This allows us to ensure consistent quality for every spool through control of every aspect of the manufacturing process.

Packaging: Every spool of Coex 3D filament is thoroughly dried in our industrial dryer before being sealed. Spools are sealed with desiccant in a 4mil thick vacuum bag.

Tested: Coex 3D doesn't just sell filament, we use it on a daily basis. Our 50+ 3D printers are constantly running with our filament. We rely on our quality as much as our customers do.
