ASA vs Fiberon PETG Spec Comparison
Material composition
Polymaker ASA 1.75mm Filament is made from ASA, a thermoplastic that combines the properties of ABS with enhanced weather resistance. It is designed for durability and impact resistance in functional parts. Polymaker Fiberon Carbon Fiber PETG uses a PETG base blended with 8% recycled carbon fiber. This composite structure improves rigidity and strength compared to standard PETG. The ASA focuses on toughness and environmental stability, while the Fiberon version prioritizes structural stiffness and reduced layer line visibility through its carbon fiber content.
Heat resistance
Heat tolerance differs significantly between these two options. Polymaker ASA withstands temperatures up to 100°C, making it suitable for high-heat environments like car accessories or outdoor RC planes. Polymaker Fiberon Carbon Fiber PETG has a Heat Deflection Temperature (HDT) of 68.6°C at 0.45 MPa. This lower threshold means the Fiberon filament is intended for moderate-temperature applications. If your project involves exposure to direct sunlight or warm interiors, the ASA provides a clear advantage in thermal stability over the PETG composite.
Print speed
Printing speed capabilities vary based on the material properties. Polymaker ASA recommends a standard printing speed of 50mm/s to ensure reliable layer adhesion and minimize warping, especially in enclosed printers. Polymaker Fiberon Carbon Fiber PETG supports much higher speeds, reaching up to 300mm/s after calibration. This five-fold increase allows for faster production of prototypes and jigs. If rapid iteration is your priority, the Fiberon filament offers superior throughput, whereas the ASA requires slower, more deliberate printing for best results.
Nozzle requirements
The abrasive nature of the materials dictates different hardware needs. Polymaker ASA is a standard thermoplastic that can be printed with most nozzles, though standard brass is sufficient for general use. Polymaker Fiberon Carbon Fiber PETG contains 8% recycled carbon fiber, which is highly abrasive. The data explicitly states that a hardened or wear-resistant nozzle is required to prevent damage from the fiber content. If you are using a standard brass nozzle, the ASA is the safer choice, while the Fiberon demands upgraded extruder hardware.
Weight and value
Package sizes differ between the two products. Polymaker ASA 1.75mm Filament comes in a 1kg spool, providing twice the material volume of the Fiberon option. Polymaker Fiberon Carbon Fiber PETG is sold in a 0.5kg size. Both filaments share the same 1.75mm diameter, ensuring compatibility with most desktop 3D printers. If you need more prints per purchase or are working on larger functional parts, the ASA offers greater material quantity. The Fiberon’s smaller size may suit users testing composite materials or needing smaller batches.
UV and weather resistance
Outdoor durability is a key differentiator for these filaments. Polymaker ASA is specifically marketed as UV and weather resistant, with added protection against environmental stress cracking. It is recommended for outdoor applications like car accessories and RC planes. Polymaker Fiberon Carbon Fiber PETG does not list UV resistance or weather stability in its specifications. It is designed for indoor functional parts, prototypes, and fixtures. If your project will face sunlight or rain, the ASA is the only suitable option among the two.
Choose based on your part needs
Outdoor RC plane builders
ASA resists UV light and weather better than standard plastics. It handles temperatures up to 100°C and offers high toughness. This makes it ideal for car accessories or outdoor models that face environmental stress. You get durable layer adhesion for real-world functional parts without rapid degradation.
Desktop printer users
This filament prints with low warping and does not require a heated chamber. It reaches speeds up to 300 mm/s after calibration. The matte finish hides layer lines for a clean look. You need a hardened nozzle due to abrasive fibers, but it works well on standard desktop machines.
Prototype bracket makers
The 8% recycled carbon fiber adds rigidity and strength compared to standard PETG. It is suitable for jigs, fixtures, and housings. The material provides stable dimensions and good layer adhesion. You get a professional appearance with reduced visibility of print lines while maintaining functional performance for moderate temperature use.
High-heat functional part users
ASA withstands higher temperatures than the Fiberon PETG, which has a heat deflection temperature of 68.6°C. The ASA holds up to 100°C, making it better for tools or parts near heat sources. You gain impact resistance and durability for mechanical applications that require reliable performance under stress and thermal load.
