Who it fits

Key specs explained for ASA

Diameter: 1.75mm

This is the standard filament width for most consumer and prosumer FDM printers. You should verify your extruder can handle this size. It ensures consistent feeding and reliable layer adhesion. If your printer requires 2.85mm, this product will not fit. This dimension is the industry norm for reliable printing.

Weight: 1KG

The spool contains one kilogram of material. This size is practical for small to medium functional parts. It fits standard spool holders on most machines. You get enough material for several prototypes without excessive weight. Larger spools may not fit in smaller printer enclosures or compact storage areas.

Heat Resistance: 100˚C

The printed parts withstand temperatures up to 100 degrees Celsius. This makes them suitable for engine bays or outdoor tools in hot climates. ABS typically handles similar heat, but ASA adds weather stability. You can trust these prints to hold shape in warm environments without deforming.

UV & Weather Resistant

ASA resists UV degradation and environmental stress cracking better than ABS. This allows you to use it for outdoor RC planes or car accessories. The material maintains strength when exposed to sunlight and rain. You avoid the brittleness that often affects standard ABS parts left outside for long periods.

Design and build details

According to the listing, this spool measures 7.87 inches in width and height, with a height of 2.36 inches. It weighs 2.2 pounds total, which includes the filament and packaging. The spool itself is sized to hold 1kg of material. This compact footprint allows it to fit on most standard FDM printer build volumes without overhang issues. You should check your printer’s dimensions to ensure the spool sits securely on your holder.

The filament diameter is listed as 1.75mm. This is the standard width for consumer and prosumer printers. It ensures consistent feeding through the extruder gear. The color is Natural, with a hex code of #Dfd3c3. This neutral tone is practical for functional parts where aesthetics are secondary to durability. The material is ASA, which combines ABS strength with weather resistance. This makes it suitable for outdoor applications like RC planes or car accessories.

The listing notes that the filament offers high toughness and impact resistance. It can withstand temperatures up to 100°C. This thermal stability is crucial for parts exposed to heat, such as engine components or tool housings. The design focuses on mechanical performance rather than visual flair. You should use an enclosed printer for large parts to prevent warping, as recommended by the manufacturer. The build quality supports reliable layer adhesion for real-world use.

Setup And Everyday Use Guide

Setting up this Polymaker ASA filament requires attention to thermal stability. The listing specifies a nozzle temperature of 250°C and a bed temperature of 90°C. These settings align with standard ABS parameters. You should adjust speeds based on your printer’s capabilities, with a recommended baseline of 50mm/s. For larger prints, an enclosed printer is necessary. This enclosure helps prevent warping, a common issue with materials that have high heat resistance. The filament withstands temperatures up to 100°C, which supports its use in functional applications. This thermal stability means your prints will maintain their shape under stress. The material offers high toughness and impact resistance. This makes it suitable for mechanical parts, brackets, and housings. You can rely on strong layer adhesion for durable performance. The natural color, identified by hex code #Dfd3c3, provides a neutral base. It is UV and weather resistant, making it ideal for outdoor projects like RC planes or car accessories. The filament is less prone to environmental stress cracking. This feature ensures longevity when exposed to the elements. You should verify your extruder handles the 1.75mm diameter correctly. Consistent feeding is key to achieving the specified mechanical properties. The 1kg spool size fits most standard printers. Technical support is available for any setting adjustments. This resource helps you achieve consistent results without guesswork. Focus on maintaining stable temperatures for optimal outcomes.

Before You Buy This ASA

You should verify your printer is enclosed. ASA shrinks as it cools, and open frames often cause warping. The listing advises an enclosed chamber for large parts to maintain dimensional accuracy. Check your extruder gear type. Some direct drive systems handle the stiffness of ASA better than Bowden setups. Ensure your build surface is compatible with high bed temperatures. You may need a PEI sheet or glue stick for reliable adhesion. This material sits between standard ABS and premium engineering plastics in the 1 options reviewed here. It offers better UV resistance than ABS but requires more care than PLA. You will need a well-ventilated workspace because ASA emits fumes during printing. Store the spool in a dry place. Moisture absorption degrades print quality over time. Keep the spool sealed when not in use to preserve its mechanical properties for future projects.

Check before you buy

• Confirm your printer has an enclosed chamber to prevent warping.
• Check if your extruder type supports rigid materials like ASA.
• Ensure you have a well-ventilated printing area for fumes.
• Verify build plate compatibility with high bed temperatures.
• Plan for dry storage to maintain filament quality.
