COEX Filaments – Recommended Nozzle and Bed Temperatures

  • COEX PLA and PLA Prime:
    • 215°-235° C
  • COEX ABS and ABS Prime:
    • 230°-250° C
    • 230°-245° C
  • PLA and PLA Prime:
    • 0°-60° C
    • Painter’s tape is recommended for unheated beds, adhesive is optional at the user’s discretion.
    • Heated bed temperature recommendation is 60° C.
    • Works with Kapton tape, PEI surfaces, PEX surfaces. Adhesive is optional at the user’s discretion.
    • Works great with our EZFlex plates!
  • ABS and ABS Prime:
    • 120° C plus some form of adhesive recommended for best results
    • Heated chamber is optional but highly recommended. Common temperature recommendations range around 60°-70° C depending on your environment.
    • Works great with our EZFlex plates and Vision Miner’s adhesive!
  • PETG:
    • 60-80° C
    • Recommended bed temperature 80° C
    • It is highly recommended to use an adhesive or protective barrier between your bed and the print. PETG can bond to build surfaces of any type, including glass and PEI.
    • Works great with our EZFlex plates and Vision Miner’s adhesive!

Why are these “Recommendations”? #

There are a large number of reasons why these temperatures are guidelines, rather than actual rules. The first and most obvious facts are that everybody’s printer is different, everybody’s environment is different, and everybody’s handling of their filament is different.

Bed adhesion, in particular, is the subject of much debate in the 3D printing industry. Some people swear by a particular adhesive, or a certain bed material (glass vs. PEI), or a combination of multiple things. Everybody struggles with adhesion at some point during their printing journey, and a new filament can sometimes bring about that struggle for even the most advanced professional.

Be patient and experiment to find what works for you. Ultimately, you will need to learn what works for your machine, your environment, and your temperament.

Why are these temperatures higher than (insert brand here)? #

Per COEX: “We suggest high temp ranges than other filament makers, because we use a high-quality resin to make our filament.  Think of it this way, the need to use higher temperatures means that the finished part will be more resistant to temperature damage.”
