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™ PA6-GF is a glass fiber reinforced PA6 (Nylon 6) filament. The material exhibits excellent thermal and mechanical properties without sacrificing the layer adhesion.
We highly recommend to use a wear resistant nozzle, to print with the PolyBox™ and to keep it at dry conditions (relative humidity of 15% or less) at all times to maintain the best printing results.
PolyMide™ PA6-GF features Fiber Adhesion™ and Warp-free™ technology
Warp-Free™ - Warp-Free™ technology enables the production of Nylon-based filaments that can be 3D printed 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™ PA6-GF is designed to work best with minimal bed temperatures.
Fiber Adhesion™ - Fiber Adhesion™ technology improves the layer adhesion of fiber reinforced materials, by optimizing the surface chemistry of the fibers to achieve better dispersion and bonding to the matrix. This results in better strength along the Z-axis and reduced mechanical anisotropy.

HP Star scientists utilize PolyMide™ PA6-GF for custom cryo boxes.
HP Star is a high-pressure research laboratory investigating environments that mimic conditions found at the core of our solar system’s largest planets.
PolyMide™ PA6-GF has been used to create cryo boxes which study elements at extremely cold temperatures. These cryo boxes are used for cryogenically cooling the diamond tips until they’re cold enough to condense samples on, either as a solid or a liquid depending on the specimen element. This allows high-pressure research experiments on solid chlorine, hydrogen sulfide, and other high-temperature superconductors. This research gives insight into the atmospheric conditions experienced by our solar system’s gas giants.
“We’ve been pouring liquid nitrogen straight into the 3D printed cryo boxes to rapidly cool our cells, we’ve experienced some non-fiber reinforced filaments crack under the heat shock, the PA6-GF performs very well when subject to these conditions.” – Dr. Dallday-Simpson
PolyMide™ PA6-GF also interfaces perfectly with Polymakers soluble support material PolyDissolve™ S1 for printing complex geometry. PolyDissolve™ S1 is engineered to bond with a wide variety of filament types from Polymakers portfolio and printed supports dissolve in regular tap water.

Nylon is one of the most popular engineering materials in the manufacturing world, its excellent mechanical and thermal properties has helped Nylon infiltrate a variety of industries. In the additive manufacturing world, Nylon materials haven’t been as popular as they have a tendency to warp when 3D Printed. Warping is a common issue when printing higher temperature filaments (ABS, PC) without the right temperature requirements however unlike ABS and PC, the reason Nylon warps is related to crystallization behavior and thus the warping is not easily controlled or prevented with printer settings / heated environments.
To combat this effect Polymaker have developed Warp-Free™ technology. The secret behind this technology is the fine controlling of the materials microstructure and the crystallization behaviour of the polymer chains. This effect results in all the internal stress that’s caused when printing to be fully released before solidification. This allows users to print on a cold bed; creating a printed part with superior flatness.
Please note this technology works best with minimal bed temperatures, Polymaker have developed the Warp-Free™ technology so users can effectively print with improved reliability without requiring an industrial 3D printer. Printing PolyMide™ PA6-CF with a high temperature heated bed or heated chamber is not recommended as the kinetic energy will cause parts to crystallize faster during printing, circumventing the technology and sometimes resulting in warping.
Fiber Adhesion™ Technology improves the layer adhesion of fiber reinforced materials, by optimizing the surface chemistry of the fibers to achieve better dispersion and bonding to the polyamide matrix. This results in better strength along the Z-axis and reduced mechanical anisotropy when compared to a pure Nylon PA6 printed parts. This in-house technology was developed exclusively to combat the problem of adding fibers to filaments. All other brand 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. Polymaker’s new technology not only solves this problem but actually increases Z axis tensile strength creating more isotropic parts that are strong in every direction.

* We highly recommend to use a wear resistant nozzle. Brass nozzles give a better thermal conductivity than hardened nozzles such as stainless steel so depending on your 3D printer, printing with extrusion temperatures closer to 300°C may be required when using specialty nozzles to ensure the correct extrusion temperature is achieved.
Note: Based on 0.4 mm nozzle and Simplify 3D v.3.1. Printing conditions may vary with different printers and nozzle diameters
PolyMide™ PA6-GF printed parts can be annealed in an oven after printing to maximize mechanical performance and heat resistance.
In some rare cases with fine or thin geometries, different annealing instructions or design considerations may be required for the best results.
Storage & Drying:
Before packaging, PolyMide™ PA6-GF is dried to ensure the best printing quality and filaments are vacuum sealed to protect the filament from moisture. When not in use PolyMide™ PA6-GF should be stored away from sunlight in the packaged resealable bag.
Nylon 6 is hygroscopic so it is highly recommended to store PolyMide™ PA6-GF in the PolyBox™ or a dry cabinet during printing to prevent moisture absorption which will lower the quality and the mechanical properties of the print The PolyBox™ keeps the filament at dry conditions (relative humidity of 15% or less).
We recommend that the material be used with the PolyBox™ to keep the filament at dry conditions (relative humidity of 15% or less) to maintain the best printing results. If the filament does absorb moisture, spools of PolyMide™ PA6-GF can be dried in a preheated convection oven at 80˚C for up to 12 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.

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.
PolyMide™ PA6-GF has been engineered so users can print strong glass fiber filled parts with excellent layer-adhesion. As the glass fiber in this material is highly abrasive we recommend customers first check that their 3D printer is equipped to print abrasive materials before purchasing this product.
Aside from wear resistance, there are a few important considerations for this material that we recommend.
Reinforced filaments tend to be much stiffer than other standard filaments and this can cause problems when passing the filament through a printer’s feeding system. For a steady and uninterrupted flow of filament, it is recommended to take extra care and make sure your filament guide system is smooth and with minimal bends. Brass nozzles give a better thermal conductivity than hardened nozzles such as stainless steel. Depending on your 3D printer, printing with extrusion temperatures closer to 300°C may be required when using specialty nozzles to ensure the correct extrusion temperature is achieved.
Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer.
Q: Can I print this material without wear resistant hardware (nozzle etc.)?
A: PolyMide™ PA6-GF contains 25% chopped glass fibers by weight which makes it very abrasive. It is important to have an abrasion resistant nozzle. It is important to have an abrasion resistant nozzle and hardware when printing this material. PolyMide™ PA6-GF can easily damage a brass nozzle after a few hundred grams of printing. Hardened nozzles are more expensive than regular brass nozzle so it is important to consider the amount of materials planned to be used. For some users it may be more cost effective to destroy one nozzle for some prints, but users are responsible for all 'wear and tear'.
Q: How well does Polymakers Warp-Free™ technology perform?
A: With Polymakers Warp-Free technology, more users can effectively print Carbon-fiber nylon with better dimensional stability than comparative nylon products. This technology works best when printing with low bed/chamber temperatures. Because the warping behavior of Nylon materials is partially related to its crystallization rate while printing. If a user does print with a high temperature heated bed or chamber, the heat will increase the crystallization rate and cause a part to warp.
Q: Is annealing PolyMide PA6-GF required?
A: After printing, annealing PolyMide™ PA6-CG prints will ensure the highest degree of crystallinity. This is a recommended step as it allows end users to get the best properties and performance from their parts. PolyMide™ PA6-GF can be annealed in a convection oven at 90˚C for 2 hours. Of course annealing may not be required for applications that don't require the best thermal or mechanical properties. In some rare cases with fine or thin geometries, different annealing instructions or design considerations may be required for the best results.
Q: Will this filament absorb moisture?
A: Yes, Polyamides are hygroscopic, meaning that they absorb moisture from the air. We recommend keeping your spool of PolyMide™ PA6-GF dry as moisture can significantly reduce mechanical properties and cause print defects such as oozing and poor surface quality. To manage moisture absorption in your filaments, it is recommended to use the PolyBox™ which provides a stable, low level humidity storage solution for filaments during and in-between printing. If PolyMide™ PA6-GF appears to have absorbed too much moisture, they can be dried in a preheated convection oven for 12 hours at 80˚C.
Q: What support materials can I use with this product?
A: Polymaker’s PolyDissolve™ S1 filament is the recommended support filament for PolyMide™ PA6-GF. If support material is required for a print, it is recommended to monitor print settings and quality for oozing and stringing; as this can dramatically affect the mechanical properties of the print. Self-support can also be used however, it is important to remove the support structures straight after printing, as prolonged exposure to atmospheric humidity can cause the support to strongly adhere to the printed part.
