Filament Spectrum ASA 275 1.75 mm — Acrylonitrile Styrene Acrylate (ASA), Navy Blue, 1 kg

Spectrum ASA 275 1.75 mm in Navy Blue is a 1 kg spool of Acrylonitrile Styrene Acrylate (ASA) filament formulated for desktop FDM/FFF 3D printers. The composition has been adjusted to improve flexibility, flow and interlayer adhesion while reducing shrinkage, making the material easier to print at relatively high speeds. ASA 275 offers enhanced UV, weather and thermal resistance compared with standard ABS, so it is suitable for outdoor-exposed parts, functional prototypes and housings that require mechanical strength and dimensional stability.

Advantages

Spectrum ASA 275 combines the outdoor durability and chemical resistance typical of ASA with improved printability: reduced warping, better flow characteristics and increased layer bonding. The modified formulation simplifies printing parameters, allowing prints with reduced risk of deformation after cooling and enabling the production of larger models. The filament is supplied vacuum-sealed on a clear spool with a desiccant to preserve material quality.

Suitable for

• Functional prototypes and end-use parts exposed to outdoor conditions
• Housings, covers and exterior components for electronics and automotive applications
• Tooling and production aids that require mechanical strength and dimensional stability
• Marine components and sports equipment parts requiring UV and weather resistance

• Designed for desktop FDM/FFF 3D printers

How to use

Load Spectrum ASA 275 into a compatible 1.75 mm extruder and follow standard ASA print settings adjusted to your printer: use an appropriate nozzle temperature and heated bed to reduce warping, enable a closed or semi-enclosed build chamber if available, and set cooling to low or moderate levels as recommended for ASA. Print speeds can be relatively high thanks to the filament's modified flow, but calibrate extrusion multiplier and retraction to avoid stringing. Store unopened spools vacuum-sealed with the included desiccant; after opening, keep the spool in a dry container or filament dryer to prevent moisture absorption that can affect print quality.

Usage recommendations

For best results with Spectrum ASA 275: print on a heated bed with good bed adhesion (PEI, glue stick or specialized ASA adhesives), use enclosure or ambient temperature control to minimise warping, and dry the filament before use if it has been exposed to humidity. Adjust first-layer settings and cooling to ensure strong interlayer bonding for mechanically loaded parts.
