PETG (PolyEthylene Terephthalate plus Glycol) is a co-polyester used in 3D printing for its durability, impact resistance, and temperature resistance. PETG is the second most popular 3D printing filament behind the ubiquitous PLA. It has qualities comparable to ABS but can be printed without an enclosure or fume handling requirements. Unlike ABS, however, PETG cannot be vapor smoothed using acetone.

Coex 3D Banana Yellow PETG is made with Virgin resin and high-quality colorant only, with no fillers.  All of Coex's filament is made in our production facility located in Wisconsin, USA. Coex 3D uses industrial-grade extruders and laser measuring quality control to ensure quality, consistency, and a 1.75±0.03mm diameter specification with every spool. We provide filament that gives excellent-looking and strong prints.

Technical Printing Guide - COEX PETG

1. Material Notes

  • Keep filament dry - store properly and dry before use
  • If needed, dry at 65°C for 3 hours or more
  • Enclosure is helpful but not mandatory
  • Use Z-offset slightly higher than 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
  • Enable cooling gradually after the first layer
  • Consider using "Extra Prime Amount" after retraction

2. Temperature Settings

Bed Temperature: 70-90°C

  • Wash the bed often for good adhesion - Use dish soap and rinse thoroughly to remove oils
  • Use bed adhesion products if necessary (gluestick, WELD3D)
  • Use brim for tall or large prints
  • Keep the ambient temperature stable

Extruder Temperature: 230-245°C

3. Basic Parameters

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 1.0-1.5mm 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:

Fan Speed Settings:

  • First Layer: 0% (fan off)
  • General Printing: 40% fan speed
  • Bridges and Overhangs: 70% fan speed
  • Layers < 30 seconds: 70% fan speed

Advanced Settings:

  • Keep Fan Always On: YES
  • Force Fan Speed for Overhangs: YES
  • Minimum Layer Time: 30 seconds
  • Force Fan Speed for Small Perimeters: YES

Additional Cooling Notes:

  • Enable gradual fan speed increase after the first layer
  • Increase fan speed for small, detailed parts
  • Consider reducing fan speed for better layer adhesion if needed
  • Monitor overhangs and bridge quality to adjust fan speed

7. Troubleshooting Guide

 Problem Solution
Irregular extrusion

1. Dry the filament

2. Check the extruder

3. Reduce speed

Poor adhesion

1. Dry the filament

2. Use 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 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. Reliability, print after print, spool after spool.

  • Quality:

    All Coex 3D 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. No need to dry when you receive your order.

  • Tested:

    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. No need to dry when you receive your order.

Beautiful and vivid yellow!

There's really no better way to describe it than "banana yellow". When I think of a classic cartoon banana, this is the color that comes to mind. COEX is one of the few brands that I can trust the filament to be dry out of the box. When I'm in a time crunch for a client, having that extra ~12hour drying time back can make the world of difference.
Not only is the filament top notch quality, the COEX team is very responsive and wonderful to work with.
