What stands out
- 2kg total weight in eight 0.25kg spools for bulk printing.
- 1.75mm filament diameter with +/- 0.02mm dimensional accuracy.
- ASA material provides UV, rain, and heat resistance.
- Vacuum sealed packaging keeps filament moisture-free.
- Recommended print speed up to 100mm/s.
Who it fits
Good fit for
You should choose this if you need durable parts for outdoor use. The ASA material resists sunlight and weather better than PLA. The bulk 8-pack is ideal for users who print frequently. You get multiple colors in one box, which saves time on color changes. The tight diameter tolerance ensures smooth feeding on most FDM printers. If you need strong mechanical parts that withstand heat, this fits your setup. The vacuum seal ensures quality from factory to printer.
Who should skip it
Skip this if you only print small prototypes occasionally. The eight-spool pack is heavy and takes up storage space. You do not need 2kg of filament for a single test print. Also, avoid this if you lack a heated bed. The recommended bed temperature is 80-120°C. Standard printers without heated beds cannot use this material effectively. Additionally, if you prefer simple materials like PLA, ASA requires higher nozzle temperatures. The recommended range is 230-260°C, which is hotter than PLA settings.
Verdict: This bulk ASA pack offers good value for users needing weather-resistant parts. The tight tolerance and vacuum sealing ensure reliable performance. It is best for frequent printers with heated beds.
Key specs explained for this ASA filament
Material Type: ASA
Acrylonitrile styrene acrylate offers high strength and toughness, surpassing standard PLA and ABS. It resists UV light, rain, and heat, making it ideal for outdoor mechanical parts. You should choose this material if you need durable items that withstand weather exposure, unlike PLA which degrades outdoors or ABS which yellows with sun exposure.
Filament Diameter: 1.75mm
This is the standard width for most FDM 3D printers. The 1.75mm size ensures wide compatibility with almost all consumer and prosumer machines. You can load this filament into your printer without worrying about feeder issues. This standard size is much more common than 2.85mm, so it fits the majority of desktop printers available today.
Dimensional Accuracy: +/- 0.02mm
Tight tolerance ensures consistent extrusion and reliable print quality. The small diameter error prevents clogs and under-extrusion issues during long prints. You benefit from smoother layer adhesion and fewer failed prints. This accuracy level is suitable for precision parts, offering better consistency than generic filaments that may vary more in thickness across the spool.
Max Print Speed: 100mm/s
The manufacturer recommends speeds between 50-100mm/s for optimal results. Printing at this range balances speed with quality, ensuring strong layer bonds. You should avoid pushing beyond this limit to maintain the material's toughness. This speed is moderate for ASA, allowing you to produce functional parts without sacrificing structural integrity or surface finish quality.
Design and Build Overview
According to the listing, each spool measures 8.00 inches in diameter, 2.50 inches in width, and features a 2.20-inch hub hole. These dimensions are designed to fit the majority of FDM 3D printers, ensuring you can hang the filament directly on your machine without adapters. The 1.75mm filament diameter maintains a dimensional accuracy of +/- 0.02mm. This tight tolerance ensures wide compatibility with almost all standard 1.75mm printers, reducing the risk of clogs or inconsistent extrusion during your prints.
The material itself is ASA, which the manufacturer states is stronger and tougher than both PLA and ABS. It is engineered to resist UV exposure, rain, and heat, making it suitable for outdoor functional mechanical parts. Each spool contains 0.25kg of filament, totaling 2kg for the entire pack. This smaller spool weight allows you to rotate and use multiple colors easily without handling heavy loads. The filament comes in vacuum-sealed, airtight packaging to keep it moisture-free from the factory to your printer.
The package includes eight distinct colors: black, white, gray, kb, gn, rd, so, and lp. This variety lets you choose based on preference and project requirements. The layout is straightforward, with no complex controls or digital interfaces. You rely on standard printer settings, with recommended nozzle temperatures between 230-260°C and bed temperatures of 80-120°C. The finish is practical, focusing on durability and ease of use rather than aesthetic embellishments.
Setup And Daily Use Guide
Setting up this filament is straightforward. The listing states that each spool features a 2.20-inch hub hole. This size is compatible with most FDM 3D printers, allowing you to hang the spool directly on your printer’s filament holder without needing adapters. The spool dimensions of 8.00 inches in diameter and 2.50 inches in width further ensure broad compatibility with standard printer setups.
The filament comes in vacuum-sealed packaging. This airtight seal keeps the ASA material moisture-free from the factory until you open it. This feature helps preserve quality and reduces the need for immediate drying before your first print. The tight dimensional accuracy of +/- 0.02mm means the filament diameter is consistent. This consistency allows for wide compatibility with almost all 1.75mm FDM 3D printers, reducing the risk of clogs or feeding issues.
For daily use, the manufacturer recommends specific printer settings. You should set the nozzle temperature between 230°C and 260°C. The bed temperature should be maintained between 80°C and 120°C. These temperatures support the material’s strength and layer adhesion. You can print at speeds ranging from 50mm/s to 100mm/s. The ASA material is noted for being tough and resistant to UV light, rain, and heat. These properties make it suitable for outdoor functional parts. The 0.25kg spool size offers a manageable amount of material for smaller projects or testing new settings without committing to a large roll.
Before You Buy This ASA
You should verify your printer’s bed temperature limits before buying. This ASA filament requires a hot bed between 80 and 120 degrees Celsius. If your machine cannot reach these temperatures, you will struggle with layer adhesion. You must also ensure your enclosure is sealed. ASA shrinks and warps easily without consistent heat retention. Check your nozzle material. Printing at 230 to 260 degrees Celsius demands hardened steel to prevent rapid wear. You should keep the vacuum seal intact until you are ready to print. Once opened, store the spools in a dry box. This 2kg bulk pack suits users who print functional outdoor parts regularly. It fits well alongside other high-strength materials in your collection. However, it is not ideal for casual hobbyists who print decorative items. You need proper ventilation and a stable environment to get good results with this tough plastic.
Check before you buy
- Verify your printer supports 80-120°C bed temperatures.
- Ensure you have an enclosed print chamber.
- Check that your nozzle is hardened steel.
- Confirm your filament holder accepts 2.20-inch hubs.
