Polymaker PolyMide CoPA Nylon 2.85mm 750g (Black)

PolyMide™ CoPA

PolyMide™ is a family of Nylon/polyamide based filaments. Produced with Polymaker’s Warp-Free™ technology, PolyMide™ filaments deliver engineering properties intrinsic to Nylon and ease of printing. PolyMide™ CoPA is based on a copolymer of Nylon 6 and Nylon 6,6. The filament combines excellent strength, toughness, and heat resistance of up to 180°C.

We recommend that this material be used with the PolyBox™ to keep it at dry conditions (relative humidity of 15% or less) at all times to maintain the best printing results.

Features:

• Excellent Toughness - PolyMide CoPA combines outstanding mechanical strength and toughness to deliver an easy-to-use filament for engineering
  applications such as gears, engine brackets, pipe connectors and high velocity air flows.
• Excellent Heat Resistance - With a high softening temperature of up to 180 °C, PolyMide CoPA is one of the most heat resistant Nylon 3D printing materials on the market.
• Warp-Free™ - PolyMide CoPA features Polymakers Warp-Free™ technology to deliver a reliable Nylon filament with excellent dimensional stability and near-zero warpage. This is achieved by the fine control of microstructure and crystallization behaviour of Nylon, which enables the material to fully release the internal stress before solidification. The Warp-Free™ technology in PolyMide CoPA is designed to work best with minimal bed temperatures.
• Improved Printability – Unlike other Nylon filaments, PolyMide CoPA is extremely easy to work with. It is compatible with most filament-based 3D printers with no heated chamber/bed required!
• Wear Resistant - Parts printed in PolyMide CoPA display fantastic wear resistance.
• Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing ensure reliable printing and consistency across spools and batches.

Post-Printing

Annealing models printed in PolyMide CoPA allows users to take advantage of the full mechanical and thermal properties of this material. Parts should be annealed shortly after the print completes.
Annealing Settings: The annealing process consists of putting the model in an oven at 80 °C for 6 hours.

What is “Dry” and “Wet” State:

Nylon materials are hygroscopic and printed parts will naturally absorb moisture from the air and become moisture conditioned. Unless your 3D printed parts operate in particularly dry environments or are post processed with a moisture barrier, it’s generally assumed that all nylon printed parts will end up in their moisture conditioned properties in every-day use.

• This is a physical reaction which is completely reversible. The water molecules act as a plasticizer inside the nylon and while it decreases tensile strength and stiffness, it increases toughness and impact resistance.
• Once the material reaches equilibrium the part has become conditioned and will stop absorbing moisture.PA6,6 materials reach equilibrium at roughly 2.5% by weight in environments at 50% R.H (Moisture Conditioned State) and reach equilibrium at 8% by weight when saturated with water (Wet State).
• Dry state data represents the testing results of PolyMide CoPA after printing and annealing the part. Moisture conditioned state represents the properties of PolyMide CoPA after annealing and conditioning at 70% relative humidity for 15 days.

Disclaimer: The typical values presented in Polymakers data sheet are intended for reference and comparison purposes only. Due to the nature of 3D printing they should not be used for design specifications or quality control purposes.

Storage: It is highly recommended to store PolyMide CoPA in the PolyBox™ to prevent moisture absorption which will lower the quality and the mechanical properties of the print. If the filament has absorbed moisture it can be dried at 80°C for 8 hours in a convection oven.
