Who it fits

Key specs explained for this bundle

Material Type: ASA

ASA stands for Acrylonitrile Styrene Acrylonitrile. This material combines the strength of ABS with better resistance to UV light and weather. You get parts that do not yellow or crack when left outside. This makes ASA ideal for garden fixtures, automotive accessories, and outdoor brackets. If you need durable functional parts for changing environments, this material offers a reliable balance of toughness and stability.

Filament Diameter: 1.75mm

This is the standard width for most consumer 3D printer filaments. A 1.75mm diameter ensures compatibility with a wide range of extruders and hotends found in modern printers. You do not need special hardware or adapters to use this roll. It feeds smoothly through the bowden tubes or direct drive systems. This standard size simplifies your workflow and allows you to swap materials easily without worrying about fitment issues.

Max Print Speed: 200mm/s

The manufacturer rates this filament for speeds up to 200 millimeters per second. This allows for faster production of functional parts compared to slower materials. You can reduce print times for large or complex objects without sacrificing layer adhesion. This speed range suits users who need to produce multiple copies or larger assemblies. It provides flexibility to balance quality and speed depending on the complexity of your specific project requirements.

Net Weight: 2KG

The bundle contains two rolls, totaling two kilograms of material. This provides enough filament for substantial projects or repeated prints. You get two kilograms of black ASA, which is useful for coordinating colors or having a backup supply. This weight supports repeat work or larger functional parts that require significant material volume. It offers a practical quantity for hobbyists and professionals who need consistent material for ongoing outdoor or mechanical applications.

Design and build details

According to the listing, this bundle includes two rolls of black ASA filament, totaling two kilograms of material. The filament diameter is 1.75mm, which is the standard size for most desktop 3D printers. ASA is an engineering plastic that offers the mechanical strength of ABS but with added resistance to UV light and weather. This means you can print functional parts that stay stable when exposed to sunlight or changing outdoor conditions. The material does not yellow or crack easily, making it suitable for garden fixtures, automotive accessories, and outdoor housings.

The bundle is designed for users who need robust, dimensionally stable prints. ASA provides excellent stiffness and resists bending or deformation under stress. You can print brackets, fixtures, and other components that require a precise fit and reliable strength. The listing notes that this filament is often perceived as less smelly than traditional ABS, though you still need an enclosed printer and good ventilation. Nozzle temperature ranges from 240 to 260°C, and bed temperature should be set between 75 and 95°C. Printing speeds can go up to 200mm/s. If the filament absorbs moisture, you can dry it at 70°C for seven hours. This practical design supports repeat work or coordinated project colors, ensuring your parts remain durable in real-world environments.

Setup and everyday use

Setting up this Polymaker ASA bundle requires specific printer conditions. You must use an enclosed printer to maintain stable temperatures and ensure good ventilation or filtration. The listing notes that while the material is often perceived as less smelly than traditional ABS, proper airflow is still necessary. For daily printing, you should set your nozzle temperature between 240 and 260 degrees Celsius. The bed temperature needs to be kept between 75 and 95 degrees Celsius. You can print at speeds ranging from 50 to 200 mm/s. If the filament absorbs moisture, you can dry it at 70 degrees Celsius for seven hours. This bundle includes two rolls of black ASA, each weighing one kilogram. This configuration supports repeat work or coordinated project colors. You can choose this option if you need consistent material for multiple functional parts. The high heat resistance of this ASA allows for printing parts that must stay stable in hot environments. With a heat deflection temperature up to 103 degrees Celsius, these prints are suitable for automotive accessories or garden fixtures. The material offers excellent stiffness and dimensional stability. This means your brackets and housings will resist bending and deformation over time. The 1.75mm diameter ensures compatibility with most standard desktop 3D printers. You get reliable strength and a precise fit for components exposed to sun and changing weather. The bundle supports higher-volume printing if you select the four-roll option, but the two-roll set is ideal for smaller batches.

Before you buy this bundle

You need an enclosed printer for this ASA bundle. The listing requires good ventilation or filtration because it still emits fumes, even if less than ABS. Verify your extruder can handle the suggested nozzle temperature range of 240-260°C. Your bed must reach 75-95°C for proper adhesion. Check that your printer’s build volume fits the parts you intend to print, as ASA shrinks slightly during cooling. You may need a brim or raft to prevent warping on large flat surfaces. This bundle contains two kilograms of black filament. If you need other colors, Polymaker offers Black+White or Black+Grey options. The Black x4 bundle suits high-volume users. Keep the filament dry. Store unused rolls in a sealed bag with desiccant. Print at speeds between 50-200mm/s for best results. This material suits outdoor brackets and automotive parts. It resists UV light and weather better than standard ABS. Ensure your workspace is clean to avoid surface defects on functional parts.

Check before you buy

• Confirm your printer is fully enclosed for heat stability.
• Check that your bed reaches at least 95°C.
• Verify your nozzle handles temperatures up to 260°C.
• Ensure you have adequate ventilation for fumes.
• Select the correct color bundle for your project needs.
