Print Parameters - COEXFLEX 40D

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

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.
