3D printer filament Asa ASA LW UltraFoam 0.75 kg — Traffic Black (SPECTRUM-81606/LWASA)

Asa ASA LW UltraFoam 0.75 kg in Traffic Black is a lightweight, foam-capable ASA filament formulated for 3D printing applications that require the chemical and weather resistance characteristic of ASA combined with reduced part weight. Designed for LW (lightweight/foamable) ASA workflows, this filament enables production of functional parts, prototypes and outdoor components with a lower material footprint while preserving the mechanical and environmental durability of standard ASA.

Advantages

The filament offers ASA-level resistance to UV exposure, moisture and common chemicals, with a formulation optimized to generate a foamed, lower-density structure during printing. This reduces filament consumption and finished-part weight without sacrificing dimensional stability. Its Traffic Black color provides a consistent, matte dark finish suitable for functional parts and visible prototypes.

Suitable for

• Lightweight functional prototypes and concept models
• Outdoor enclosures, brackets and fixtures exposed to sunlight
• Parts requiring improved stiffness-to-weight ratio
• Applications where reduced material use and faster printing are beneficial

Key specifications

• Material type: ASA (lightweight / foamable grade)
• Net spool weight: 0.75 kg
• Color: Traffic Black (matte dark finish)
• Compatibility: standard FDM/FFF 3D printers that support ASA and LW/foamable filaments
• Performance: UV and weather resistance typical of ASA; formulated for foaming to reduce density

How to use

Load the filament into an FDM/FFF printer configured for ASA-type materials and follow the printer manufacturer's guidelines for heated bed and nozzle temperatures. Adjust extrusion multiplier and layer settings as required to promote controlled foaming—start with recommended ASA print temperatures and gradually tune retraction, print speed and flow to achieve the desired cellular structure. Ensure adequate part cooling and allow printed parts to cool gradually to minimise warping. Use an enclosed build chamber or heated bed where possible to maintain dimensional accuracy during printing.

Usage recommendations

Store the filament in a dry, sealed container with desiccant to prevent moisture uptake. For outdoor use, consider post-processing such as sanding and UV-resistant coatings if a specific surface finish or long-term color stability is required. Test small samples to determine optimal printer settings for foaming behavior before producing final parts.
