Who it fits
Good fit for
You should choose this filament if you print functional outdoor items like RC planes or car accessories. The high heat resistance and UV stability make it ideal for parts exposed to sunlight and temperature changes. Users who need chemical resistance for tools or engine components will benefit from its solvent durability. The tight +/- 0.02 mm tolerance suits printers requiring precise dimensions for mechanical assemblies. It is a practical choice for makers who prioritize long-term material integrity over aesthetic finishes.
Who should skip it
Skip this option if you need a material that prints easily without ventilation. ASA typically requires an enclosed chamber and proper exhaust due to fumes during printing. If you lack a well-ventilated workspace, the fumes may be unpleasant or unsafe. You should also look elsewhere if you prioritize low warping or easy removal without a heated bed. This filament is designed for durability, not for quick, simple prints. If you need flexible or low-odor materials for indoor hobby projects, this ASA spool is not the right fit.
Verdict: This 1.75 mm black ASA filament delivers robust UV and heat resistance for functional outdoor parts. Its tight dimensional tolerance ensures reliable performance for precision mechanical prints.
Key specs explained for ASA
Material Type: ASA
ASA stands for Acrylonitrile Styrene Acrylonitrile. This plastic shares the strength of ABS but adds superior resistance to sunlight and weather. You should choose this material for parts that stay outside, like car accessories or RC planes. It handles heat well, keeping its shape up to 93°C. It also resists oils and solvents. This makes it ideal for functional outdoor gear that must endure daily exposure without degrading or becoming brittle over time.
Filament Diameter: 1.75mm
This is the standard width for most desktop 3D printers. You will find this size works with the majority of extruders and hotends available today. It ensures smooth feeding into your printer without jamming. If you switch printers, this diameter remains the safe default. It allows for consistent flow rates, which helps maintain layer adhesion and surface finish. Stick to this size unless your specific machine requires a different gauge for specialized applications.
Dimensional Accuracy: +/- 0.02mm
This tolerance level means the filament thickness varies by only two hundredths of a millimeter. This precision ensures consistent extrusion, preventing blobs or gaps in your prints. You benefit from reliable part dimensions and smoother surfaces. Compare this to cheaper filaments that may vary by 0.05mm or more. Tighter tolerance reduces clogging risks and improves print quality. It is especially important for detailed models or parts that need to fit together precisely without post-processing adjustments.
Net Weight: 1kg
Each spool contains exactly one kilogram of filament, which equals 2.2 pounds. This is a standard volume for hobbyist and professional printing. It provides enough material for multiple medium-sized projects. You can plan your prints based on this known quantity. It fits standard spool holders and storage containers. This weight offers a balance between portability and value, allowing you to stock up without excessive bulk or storage challenges for your workspace.
ASA Material And Spool Design
The listing describes this filament as black ASA plastic. ASA shares the structural strength of ABS but adds superior resistance to UV light and weather. According to the listing, this material does not shrink significantly when exposed to sunlight. It also handles heat well, maintaining its shape up to 93°C. This makes it suitable for parts that face outdoor conditions or chemical exposure. You should use this for functional items like RC planes or car accessories that need to stay stable in heat or oil.
Each spool holds 1 kg of material. The filament diameter is 1.75 mm with a tight tolerance of +/- 0.02 mm. The listing states that advanced CCD measurement ensures 99% of the strand meets this precision. Consistent diameter helps your printer extrude material smoothly without clogs. The filament is dried for 24 hours and vacuum-sealed to prevent moisture issues. This preparation supports a bubble-free print experience.
The spool itself measures 7.87 inches wide and 2.56 inches high. It weighs 2.2 pounds total. These dimensions fit standard 3D printer filament holders. The black color provides a neutral finish for mechanical parts. If you need other colors, the listing notes seven options exist, including blue and natural. This variety allows you to match aesthetic needs while keeping the durable ASA properties.
Setup and daily use guide
You load the 1 kg spool into your printer’s filament drive. The listing states the filament diameter is 1.75 mm with a tight dimensional accuracy of +/- 0.02 mm. This precision helps ensure consistent extrusion. You will likely need a heated bed and an enclosed chamber, as ASA behaves like ABS but with better UV stability. The material is designed for functional parts that require strength and durability.
The spool measures 7.87 inches in width and height, with a height of 2.56 inches. It fits standard 3D printers that accept 1.75 mm filament. The black color is one of seven options available, including blue, natural, and green. Each spool contains 2.2 pounds of material. The filament is dried for 24 hours and vacuum-sealed to prevent moisture absorption. This process aims to keep the filament clog-free and bubble-free during printing.
In daily use, this ASA filament handles temperatures near 93°C. It resists chemicals, oils, and solvents. This makes it suitable for car accessories or RC planes. The UV stability means the prints do not shrink significantly when exposed to sunlight. You can trust the advanced CCD diameter measurement to maintain consistency. The adaptive control systems help ensure smooth printing. You should store the spool in a dry place after opening to maintain its quality. The material’s chemical resistance adds to its practicality for outdoor applications. This setup allows you to create durable parts without significant warping or shrinking issues.
Before You Buy ASA Filament
You should verify your printer accepts 1.75 mm diameter spools. This FLASHFORGE filament comes in a 1 kg weight, which fits most standard drives. ASA requires higher nozzle temperatures than PLA. You must ensure your extruder and hotend handle these heat levels safely. An enclosed chamber is highly recommended. ASA tends to warp if it cools too quickly. The listing notes good chemical resistance, so you can use it for functional parts exposed to oils or solvents. UV stability makes it suitable for outdoor items like car accessories. You need to store the vacuum-sealed spool properly. Moisture absorption degrades print quality over time. Keep it in a dry box when not in use. This material sits alongside other engineering plastics in 1 options. It offers better weather resistance than ABS but requires more careful printing conditions. Check your printer’s maximum temperature limits before purchasing.
Check before you buy
- Confirm your printer supports 1.75 mm filament diameter.
- Verify your hotend handles ASA's high printing temperatures.
- Ensure you have an enclosed chamber to prevent warping.
- Check if your printer accepts the 1 kg spool size.
- Plan for dry storage to maintain filament quality.
