Polymaker Fiberon PA6-CF20 1.75mm Filament 3kg (Formerly PolyMide PA6-CF)

Are you looking to buy Polymaker Fiberon PA6-CF20 1.75mm Filament 3kg (Formerly PolyMide PA6-CF) in Australia?

Fiberon™ is polymakers family of fibre-reinforced composite filaments developed to provide outstanding mechanical performance for a range of engineering applications.

Fiberon™ PA6-CF20 is a carbon fibre reinforced nylon filament featuring 20% chopped carbon fibres by weight. Within Polymakers range of nylon filaments, Fiberon™ PA6-CF20 delivers best in class stiffness, strength and heat resistance and superior z axis tensile strength to outperform many other functional 3D printing materials in "dry state". Together with 20% industrial chopped carbon fibres, Polymakers Fibre-Adhesion™ technology optimises the surface chemistry of the fibres to achieve better dispersion and bonding to the Nylon 6 matrix and delivers an outstanding filament for functional applications.

Features

• Excellent Stiffness & Strength - Featuring a tensile modulus up to 8.4 GPA on the XY axis and 3.7 GPA on the Z axis, Fiberon™ PA6-CF20 is well suited for high performance industrial and engineering applications. Fiberon™ PA6-CF20 combines extreme stiffness and best-in-class tensile strength. Fiberon™ PA6-CF20 is an excellent choice for dry applications[1] requiring stiffness and durability such as automotive brackets, jigs, ESD safe fixtures, aerospace, prosthetics and engineering.
• Excellent Heat Resistance - Featuring a high heat resistance up to 215°C after annealing[2], Fiberon™ PA6-CF20 offers excellent heat resistance for demanding applications where heat and stress are critical design factors. This material lends itself perfectly to functioning automotive applications where a combination of heat resistance and mechanical properties are required. 
• Outstanding Layer Adhesion - Most fiber reinforced materials show a decrease in z-axis layer adhesion when compared with their non-fiber reinforced Nylons, producing a part that is only stronger on the X-Y axis but detrimental to the Z axis. Polymakers new technology in Fiberon™ PA6-CF20 not only solves this problem but actually increases Z axis tensile strength creating more isotropic parts that are strong in every direction.
• Warp-Free™ - Fiberon™ PA6-CF20 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 Fiberon™ PA6-CF20 is designed to work best with minimal bed temperatures.
• Wear Resistant and Tough - Parts printed in Fiberon™ PA6-CF20 display excellent toughness and wear resistant properties.
• Improved Printability – Unlike many other Nylon filaments, Fiberon™ PA6-CF20 is extremely easy to work with, exhibiting excellent dimensional stability. It is compatible with most filament-based 3D printers with no heated bed or chamber required!
• Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing ensure reliable printing and consistency across spools and batches.

[1] Most Nylon parts in the real world undergo a process called "Moisture conditioning" which improves toughness and flexibility of the Nylon while reducing tensile strength and stiffness. Unless protected with a moisture barrier, PA6-CF shows a greater change in mechanical properties when subjected to water / high humidity in comparison to long-chain nylon filaments like PA12-CF or PA612-CF. In simple terms PA6-CF will typically offer the best properties in a dry application, but for a wet or high humidity application a longer chain nylon such as PA612 or PA12 may be better. See "Specifications & FAQ" tab to learn more about what moisture conditioning is, how it works and if it's relevant to your application.
[2] Fiberon™ PA6-CF20 displays the best mechanical and thermal properties when fully crystallized. The printed part will not reach full crystallization during the printing process, an additional step is required: Annealing. Fiberon™ PA6-CF20 can be annealed in the oven at 100˚C for 16 hours right after the printing process.

Nylon is a semi-crystalline material, it's crystalline regions offer many properties, but in particular their structure deliver the heat resistance that nylon is known for. Annealing after printing is a critical process to achieve consistent crystallinity and complete the production process of nylon parts.

Mechanicla Properties

Dry state represents when PA6-CF20 part is printed and annealed.
Wet state represents if the PA6-CF20 part were submerged in water for 48 hours.

If your part is exposed to reasonable humidity (70% RH) but isn't exposed to water, your part would become moisture conditioned. To enter the wet state would require very high humidity, steam or submersion.

Nylon 6 based materials are moisture sensitive and their mechanical properties change. As they absorb moisture the toughness and flexibility increase, while tensile strength and stiffness decrease. This process is not permanent, if the part were dried, it would regain strength and stiffness.
