C♻EXNext  1.75mm

COEX is helping make the world a better place one spool of PLA at a time. C♻EXNext PLA, is made from recycled scrap materials from our production process.

Coex 3D C♻EXNext PLA - The most environment-friendly 3D filament solution. Because of its low toxicity and ease of printing, PLA (Polylactic Acid) filament is a very popular choice in the 3D printing community. It looks great, is extremely easy to print with, and has generally good mechanical properties. It's perfect for prototypes and decorative models. We provide filament that gives excellent-looking and strong prints.

Coex's PLA is made with Virgin NatureWorks Ingeo 4043D resin, high-quality colorant only, and no fillers.

All of Coex 3D's filament is made in our production facility located in Wisconsin, USA.

As good or better than most competitors + or prime.


Recommended Print Settings

  • Hotend Temperature: 215 °C - 235 °C
    • Important! This temperature range may seem hotter than you're used to for other PLA filaments. Using 100% virgin resin causes our PLA to require slightly higher printing temperatures.
  • Bed Temperature: 0 °C - 60 °C
  • Recommended Build Surfaces/Adhesives: Glass, PEI Build Surface, Magigoo, Painter's Tape, Glue Stick

Technical Printing Guide - COEX PLA

1. Material Notes

  • Keep filament dry - store properly and dry before use
  • PLA is less hygroscopic than other materials, but proper storage helps maintain quality
  • If needed, dry at 55°C for 3 hours or more
  • Check for any visible damage before use

2. Temperature Settings

Bed Temperature: 60°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 ambient temperature stable

Extruder Temperature: 215-235°C

3. Basic Parameters

PLA (Polylactic Acid) is a biodegradable polymer known for its ease of printing, good surface quality, and dimensional accuracy. Perfect for decorative parts, prototypes, and general printing needs where mechanical properties are not critical.

6. Cooling Settings

Cooling Configuration:

  • First Layer: 0% (fan off)
  • General Printing: 100% base fan speed
  • Bridges and Overhangs: 100% fan speed
  • Layers < 15 seconds: 100% fan speed

Critical Considerations:

    • PLA requires maximum cooling for best results
    • Full fan speed helps with bridging and overhangs
    • The first layer needs no cooling for good adhesion
    • Small parts need maximum cooling

7. Troubleshooting Guide

 Problem Solution
Poor Layer Adhesion

 

1. Increase temperature by 5-10°C

2. Reduce cooling fan speed for first few layers

3. Clean build surface with IPA

 
Warping

1. Increase bed temperature to 60°C

2. Add brim (5-10mm)

3. Ensure no drafts in printing area
Stringing

1. Lower temperature by 5°C

2. Increase retraction speed to 45mm/s

3. Adjust retraction distance
Under-extrusion

1. Increase temperature by 5-10°C

2. Clean nozzle or try cold pull

3. Check filament quality
Poor Overhangs

1. Ensure 100% cooling

2. Reduce temperature by 5°C

3. Reduce print speed by 50%

 

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.
