YXPOLYER Nylon Filament PA6 1.75mm
This white 1.75mm nylon filament claims over tenfold toughness and high impact strength compared with PLA. It handles temperatures up to 381°F (194°C), enabling reliable performance in demanding environments. The spool is heat-resistant and AMS-compatible, supporting long, high-performance prints. Its low friction and abrasion resistance make it well-suited for gears, bearings, and moving components where wear resistance is critical. Nylon’s chemical resistance also adds stability in oils, greases, and solvents, broadening its industrial appeal.
Print considerations: low moisture sensitivity is common with nylon blends, so proper storage helps maintain print quality. When printing on a capable hotend and heated bed, expect strong layer adhesion and durable finished parts that tolerate stress testing and functional use.
Creality Nylon Filament 1.75mm
Creality’s nylon filament is designed for durability and flexibility, making it suitable for items that require bending without breaking. The 1.0 kg spool provides robust material for functional parts, while the filament’s heat resistance supports use in moderately demanding environments. The formulation emphasizes chemical resistance and a low friction profile, helping parts slide smoothly against other surfaces. The combination of strength and adaptability makes this filament a practical choice for mechanical prototypes, tool handles, and fixtures that demand longevity.
OVERTURE Nylon Filament 1.75mm
OVERTURE’s 1.75mm copolymer nylon focuses on stability and ease of use. This 1 kg spool is designed to minimize warping and moisture sensitivity, with a strong emphasis on durability for engineering parts. The packaging includes practical reel features to help manage filament length and feeding, contributing to smoother prints. Expect strong tensile properties, suitable for functional components like brackets and fixtures while maintaining dimensional fidelity across complex geometries.
SUNLU Easy PA Filament 1.75mm
SUNLU EASY nylon filament blends PA6/66 for robust strength and impact resistance. The material is designed to minimize shrinkage and warp, enabling reliable printing of complex shapes with good dimensional accuracy. Its low friction helps parts glide smoothly, and the polymer’s durability is well-suited for gears, housings, and precision fixtures. The 1 kg spool format supports longer print runs without frequent restocks, making it a practical option for ongoing projects.
Polymaker Fiberon PA6-GF 1.75mm
Fiberon PA6-GF is a glass fiber-reinforced nylon filament from Polymaker. It brings a high stiffness and improved heat resistance due to carbon reinforcement. The 1.75mm diameter and 0.5 kg spool provide a balance of performance and material handling. It suits industrial tooling, automotive components, and end-use parts where torsion and impact resistance are essential. The filament prints with good first-layer adhesion and stable mechanical properties, reducing print defects associated with ordinary nylon blends.
Polymaker Fiberon PA6-CF Carbon Fiber Nylon Filament 1.75mm
Polymaker’s PA6-CF combines nylon with carbon fiber reinforcement for exceptional stiffness, impact resistance, and heat tolerance. The black filament maintains warp resistance and features a favorable heat deflection profile. Its 0.5 kg spool supports targeted projects or test runs, and the material is well-suited for high-performance parts like brackets, jigs, and drone components that demand rigidity without excessive weight.
Buying Guide: Nylon Filament For 3D Printing
Key purchase considerations help buyers select the best nylon for their printing needs. Each filament type offers trade-offs among strength, stiffness, moisture sensitivity, and printability. Here are the main factors to compare:
- Material composition: Pure nylon (PA6/PA12), copolymers, and fiber-reinforced variants offer different balances of toughness, flexibility, and moisture sensitivity. Copolymers generally print with fewer moisture-related issues.
- Moisture management: Nylon absorbs moisture from the air, which can cause printing defects. Look for packaging that includes desiccants, or plan for proper dry-box storage and pre-drying before printing.
- Print temperature and bed temperature: Nylon typically requires higher nozzle temperatures and heated beds. Ensure your printer can handle elevated temperatures and has good bed leveling to avoid warping.
- Dimensional stability: Filaments with moisture-reducing formulations or fiber reinforcements (e.g., GF or CF) help maintain dimension accuracy across complex geometries and larger prints.
- Surface finish and post-processing: Carbon fiber-reinforced nylons can be more abrasive to nozzles and may require hardened steel or ruby nozzles. Surface finish varies with fiber content and print speed.
- Application fit: For gears and moving parts, select low-friction and high-toughness formulations. For load-bearing frames, consider high stiffness and heat resistance, possibly with fiber reinforcement.
- Printer compatibility: Check your printer’s compatibility with 1.75 mm filaments, supported bed temperatures, cooling, and enclosure needs to optimize layer adhesion and print reliability.
Practical tips: store nylon spools in sealed containers with desiccants, dry before printing if needed, and calibrate settings for first-layer adhesion, retraction, and print speed to minimize warping. Consider starting with standard test prints (calibration cubes, functional brackets) to evaluate dimensional accuracy and mechanical properties before committing to larger builds.
