Who it fits

Key specs explained for ASA

Material Type: ASA

ASA stands for Acrylonitrile Styrene Acrylonitrile. This material blends the mechanical strength of ABS with improved resistance to UV light and weather. You benefit from parts that do not yellow or crack when used outdoors. Compare this to standard PLA, which degrades quickly in sunlight, or ABS, which lacks the same level of environmental durability for long-term exterior projects.

Filament Diameter: 1.75mm

This is the standard width for most consumer 3D printers. You can load this filament into nearly any desktop FDM printer without needing adapters or special extruders. It ensures consistent flow through the nozzle. Compare this to 2.85mm or 3.00mm filaments, which require specific hardware and are less common in home workshops, making 1.75mm the practical choice for compatibility.

Net Weight: 1kg

The spool contains one kilogram of material. This size is ideal for small to medium-sized prints or for testing new designs before committing to larger batches. It offers a manageable weight for storage and handling. Compare this to 2kg or 5kg spools, which are better for industrial volume but may be too large for compact printers or limited workspace environments.

Color: White

The filament is white, identified by hex code #Dbd7d6. This color provides a neutral base for functional parts or outdoor fixtures where a clean appearance is desired. You can paint over it if needed. Compare this to black or grey options, which might hide surface imperfections better but offer less versatility for color-coding projects or matching light-colored surroundings.

ASA Filament Design and Build

The listing specifies a net weight of 1kg for this spool. The filament diameter is 1.75mm, which is the standard size for most desktop 3D printers. You need to ensure your printer’s extruder can handle this width. The material type is ASA. This plastic combines the toughness of ABS with added resistance to UV light and weather. You should use it for parts that will sit outside, like RC planes or car accessories. It resists environmental stress cracking better than standard ABS.

According to the listing, you should set your nozzle temperature to 250°C and the bed temperature to 90°C. The recommended printing speed is 50mm/s. These settings are similar to those for ABS filament. You may need to adjust them based on your specific machine. The listing advises using an enclosed printer for large parts. This helps prevent warping during the cooling process. The filament comes in a white color, identified by hex code #Dbd7d6. This neutral shade works well for functional prototypes and mechanical brackets. It provides strong layer adhesion for durable real-world applications. You can also choose from other colors if you prefer. The spool dimensions are 7.87 inches wide and 2.36 inches high. This fits standard storage spaces on most printer beds.

Setup and everyday use

You need to adjust your printer settings before loading this 1.75mm ASA filament. The listing recommends a nozzle temperature of 250˚C. You should set your bed temperature to 90˚C. A print speed of 50mm/s is suggested as a starting point. You can adjust these values based on your specific machine. Standard ABS settings often work well here. ASA shares similar properties with ABS. You must use an enclosed printer for large parts. This prevents warping during the cooling phase. The material is UV and weather resistant. You can use it for outdoor applications like RC planes. Car accessories also benefit from this resistance. The plastic is less prone to environmental stress cracking. You get high heat resistance up to 100˚C. This makes the prints suitable for functional uses. The filament offers strong layer adhesion. You can print mechanical parts, brackets, and housings. The material combines strength with rigidity. It is durable for real-world tools. You can reach out for lifetime technical support if you have issues. The spool size is 1kg. This fits most standard desktop printers. You need to ensure your extruder handles the 1.75mm diameter. The white color is identified by hex code #Dbd7d6. You can choose from other colors if needed. There are thirty variations available. You can select grey, black, red, blue, purple, or natural shades. The net weight is one kilogram. The gross weight is 2.2 pounds. You should store the filament in a dry place. This maintains its quality for future prints.

Before You Buy This ASA Filament

You should verify your printer enclosure status before printing. ASA warps easily if the chamber cools too fast. An enclosed build volume helps maintain the required 90°C bed temperature. You may also need a HEPA filter or active carbon scrubber. ASA emits styrene fumes during extrusion at 250°C. Proper ventilation is essential for safe indoor use. Check your extruder gears for wear. ASA is abrasive and can accelerate wear on direct drive systems. Consider using hardened steel nozzles to extend component life. This 1kg spool fits standard 7.87-inch diameter reels. Ensure your printer’s filament sensor aligns with this spool width. Compare this option against PLA for indoor decor or PETG for general utility. ASA suits functional outdoor parts where UV resistance matters. You get strong, durable layers suitable for brackets or car accessories. Plan your print orientation to minimize support structures and surface roughness.

Check before you buy

• Confirm your printer has an enclosed build volume to prevent warping.
• Ensure adequate ventilation or a HEPA filter for styrene fumes.
• Check if your extruder gears handle abrasive ASA material.
• Verify your spool holder fits the 7.87-inch reel width.
• Use a hardened steel nozzle to reduce wear from ASA.
