Filament Spectrum ASA 275 1.75 mm — Acrylonitrile styrene acrylate (ASA), White, 1 kg

Spectrum ASA 275 1.75 mm filament in Polar White is an ASA (acrylonitrile styrene acrylate) material supplied on a 1 kg spool designed for FDM/FFF desktop 3D printers compatible with 1.75 mm filament. The filament formulation has been modified to improve flexibility, flow characteristics and interlayer adhesion while reducing shrinkage, which simplifies printing and enables production of larger models with reduced risk of deformation. Spectrum ASA 275 offers enhanced UV and weather resistance compared with ABS, making it suitable for outdoor parts, functional prototypes and durable mechanical components that require thermal and light stability.

Advantages

Spectrum ASA 275 features reduced shrinkage and improved flow for more consistent extrusion and easier printing. The modified composition increases layer adhesion and flexibility, allowing higher printing speeds and larger builds with fewer defects. Its UV and thermal resistance provides better long-term dimensional stability and surface retention in outdoor or sun-exposed applications. The filament is supplied vacuum-packed with a desiccant and wound on a transparent spool labeled with material type, diameter and recommended temperatures.

Suitable for

• Outdoor housings and components exposed to sunlight and weather
• Functional prototypes and end-use parts requiring toughness
• Tooling and production jigs
• Automotive and marine exterior components
• Custom mechanical parts and durable consumer items

How to use

Load the 1.75 mm Spectrum ASA 275 filament into an FDM/FFF printer configured for ASA-compatible temperatures and extrusion settings. Use the temperature range and retraction settings recommended on the spool label or the manufacturer's guidelines; adjust bed temperature, enclosure and cooling to minimize warping and maximize adhesion. Print on a prepared build surface (e.g., heated bed with appropriate adhesion aid) and consider using an enclosure or controlled ambient temperature for larger parts. After printing, allow parts to cool gradually to reduce internal stresses.

Usage recommendations

For best results when printing with Spectrum ASA 275, use a heated bed and, when possible, an enclosed printing area to maintain stable ambient temperature. Store unused filament vacuum-sealed with desiccant to prevent moisture uptake. If necessary, perform a temperature calibration tower to fine-tune nozzle temperature for optimal surface finish and mechanical performance.
