Polymaker vs CHCKX Filament Specs
Compatible Material
The choice between ASA and PLA defines your project scope. Polymaker ASA is an engineering-grade polymer designed for durability. It resists UV rays and weather, making it ideal for outdoor parts like RC planes or car accessories. It withstands heat up to 100°C and offers high impact resistance. CHCKX offers PLA, a standard consumer-grade material. It is suitable for general-purpose prints and indoor use. PLA does not provide the same environmental or thermal resilience as ASA. If you need functional, weather-resistant parts, Polymaker ASA is the superior technical choice. For simple models, CHCKX PLA is sufficient.
Printing Temperature
Nozzle temperature requirements differ significantly between these two filaments. Polymaker ASA requires a nozzle temperature of 250°C. This high heat is necessary to manage the material’s stiffness and ensure proper layer adhesion. You must also maintain a bed temperature of 90°C to prevent warping, especially in large parts. CHCKX PLA operates at a much lower range of 200-220°C. The bed temperature for PLA is 70-80°C. These lower settings make CHCKX PLA easier to print on open-frame printers without needing an enclosure. Polymaker ASA often requires an enclosed printer to maintain the necessary thermal stability. Your printer’s maximum nozzle temperature must be at least 250°C for Polymaker.
Dimensional Accuracy
Print quality relies heavily on filament consistency. CHCKX PLA specifies a diameter accuracy of +/- 0.03 mm. This tight tolerance ensures smooth feeding into the extruder and reduces the risk of clogs or under-extrusion. The data does not list a specific dimensional tolerance for Polymaker ASA. However, Polymaker is known for reliable layer adhesion and mechanical properties. CHCKX also notes that its filament is dried for 24 hours and vacuum sealed, which helps prevent bubbling. Without a stated tolerance for Polymaker, CHCKX provides a verifiable metric for precision. This makes CHCKX the safer bet if dimensional consistency is your primary concern.
Print Speed
Recommended print speeds affect your project timeline. Polymaker ASA suggests a speed of 50mm/s. This moderate pace helps manage the material’s tendency to warp and ensures strong bonding between layers. The data does not provide a specific speed recommendation for CHCKX PLA. Generally, PLA can be printed faster than ASA due to its lower melting point and easier flow characteristics. However, without explicit data for CHCKX, we cannot confirm if it supports higher speeds. Polymaker’s 50mm/s recommendation prioritizes quality and structural integrity over raw speed. If you are printing large ASA parts, sticking to this speed is advisable to avoid defects.
Packaging and Moisture Protection
Filament storage impacts print success. CHCKX PLA is thoroughly dried for 24 hours before packaging. It is vacuum sealed in nylon bags with desiccant to protect against moisture. This process helps prevent clogging and bubbling issues during printing. The data does not mention specific drying or packaging protocols for Polymaker ASA. While Polymaker ASA is also sensitive to moisture, CHCKX provides explicit details on its moisture management. Vacuum sealing with desiccant is a best practice for maintaining filament quality. This attention to packaging ensures that CHCKX PLA arrives ready to print with minimal risk of moisture-related defects.
Choose Your Filament Wisely
Outdoor RC plane builders
You need ASA filament for parts that face the elements. Polymaker ASA resists UV rays and weather. It handles temperatures up to 100°C. This ensures your RC plane or car accessory lasts. The material offers high toughness and impact resistance for real-world use.
Indoor hobbyists printing models
You want smooth, colorful prints for indoor projects. CHCKX PLA is dried for 24 hours to prevent clogs. It winds neatly to reduce breakage. The filament feeds consistently in most 1.75mm printers. You get vibrant colors without complex settings or enclosure needs.
Functional prototype makers
You require durable parts like brackets or housings. Polymaker ASA provides strong layer adhesion and rigidity. It shares ABS properties but adds weather resistance. This makes it suitable for mechanical parts and tools. The high heat tolerance ensures the part holds up under stress.
General purpose print users
You need reliable material for everyday prints. CHCKX PLA works with almost all 1.75mm FDM printers. It is vacuum packed with desiccant to stay dry. The accuracy is plus or minus 0.03 mm. This consistency helps you avoid printing failures and achieve clean results.

Frequently asked questions
Is Polymaker ASA better than CHCKX PLA for outdoor use?
Yes, for outdoor applications, Polymaker ASA is the superior choice. It is engineered to resist UV rays and weather exposure, ensuring durability for parts like RC planes or automotive accessories. CHCKX PLA is designed for indoor use and lacks the environmental resistance required for exterior projects. If your parts will face the elements, ASA provides the necessary stability.
Which filament offers better temperature resistance?
Polymaker ASA offers significantly higher temperature resistance than CHCKX PLA. ASA can handle temperatures up to 100°C, making it suitable for functional parts that may experience heat. PLA, offered by CHCKX, is a standard consumer-grade material with lower thermal stability. If your project involves heat exposure, Polymaker ASA is the robust option.
Do I need an enclosed printer for Polymaker ASA?
You likely need an enclosed printer for Polymaker ASA. The material is best suited for enclosed printing environments to manage warping and maintain consistent temperatures during the print. While CHCKX PLA is designed for general indoor printing with consistent feeding, ASA requires more controlled conditions to achieve optimal results for large functional components.
What is the difference in filament diameter compatibility?
Both Polymaker ASA and CHCKX PLA are compatible with 1.75mm FDM printers. This standard diameter ensures they fit most common desktop 3D printers. The primary difference lies in the material chemistry, not the physical dimensions. You can use either filament in printers designed for 1.75mm spools without needing adapter hardware or different nozzle sizes.
Is CHCKX PLA suitable for functional prototypes?
CHCKX PLA is better suited for general indoor printing rather than heavy-duty functional prototypes. It provides stable feeding and moisture protection, prioritizing consistent diameter and tangle-free operation. Polymaker ASA is designed for robust, weather-resistant functional parts. If you need durability and environmental resistance, Polymaker ASA is the stronger choice for functional applications.
How do the spool weights compare between the two brands?
The spool weights differ slightly between the two options. Polymaker ASA weighs 2.2 pounds, while CHCKX PLA weighs 2.65 pounds. Both come in standard 1kg sizes. This weight difference is minimal and unlikely to affect your printer's performance. You can choose based on material properties rather than spool weight considerations.
