ROSA3D ASA Filament 1.75mm 1kg Gray Refill

ROSA3D ASA filament 1.75mm 1kg Gray Refill is a high-performance 3D printing material engineered for demanding outdoor and industrial applications. This thermoplastic is specifically formulated to provide exceptional resistance to UV radiation, moisture, and thermal stress, making it a superior alternative to standard materials for parts exposed to harsh weather conditions. The refill format is designed to minimize environmental impact by allowing users to utilize their existing reusable spool systems, reducing plastic waste while maintaining high-quality printing standards.

Advantages

The primary benefit of this ASA filament is its remarkable durability and stability in outdoor environments, where it maintains its structural integrity and color without degrading under direct sunlight. Compared to ABS, this material exhibits significantly lower shrinkage during the printing process, which reduces the risk of warping and improves dimensional accuracy. Furthermore, it produces fewer irritating vapors during extrusion, creating a more comfortable working environment. With a high Vicat softening point of approximately 94°C, printed components remain stable even in high-temperature settings, ensuring reliability for functional prototypes and end-use parts.

Suitable for

• Outdoor structural components and housings
• Automotive exterior parts such as sensor covers and mirror housings
• Marine equipment and accessories
• Functional prototypes requiring thermal and mechanical stability
• Industrial parts exposed to varying weather conditions

When it may not be suitable

This filament may not be the best choice for users without access to a 3D printer equipped with a heated build chamber, as ASA is prone to warping if the ambient temperature is not controlled. It is also less suitable for simple, indoor decorative prints where the high thermal and UV resistance properties are not required, as more user-friendly materials like PLA may be easier to process.

Key specifications

• Diameter: 1.75 mm
• Weight: 1 kg
• Color: Gray
• Extrusion temperature: 220-250°C
• Bed temperature: 90-110°C
• Vicat softening point: 94°C
• Tensile strength: 40 MPa
• Diameter tolerance: +/- 0.05 mm

How to use

To achieve optimal results, ensure your 3D printer is enclosed to maintain a stable temperature throughout the printing process. Load the filament onto your existing reusable spool. Before starting, ensure the print bed is clean and properly leveled. For improved first-layer adhesion, you may apply an ASA slurry, which consists of small pieces of the filament dissolved in acetone. Monitor the first few layers closely to ensure proper bonding to the build surface.

What to consider before purchase

• Ensure your printer is capable of reaching the required bed and nozzle temperatures.
• Verify that your printer has a closed chamber to prevent warping.
• Confirm that you have a compatible reusable spool system for the refill format.
• Consider the need for proper ventilation in your workspace.

Usage recommendations

For the best mechanical properties and surface finish, print in a closed chamber and avoid direct drafts. If you experience adhesion issues, ensure the bed temperature is set within the recommended 90-110°C range and consider using an adhesive aid.
