Filament ROSA3D ASA black – ROSA3D-3075 (3D printing material)

ROSA3D ASA black (ROSA3D-3075) is a thermoplastic filament formulated for FDM/FFF 3D printing. As an ASA material it provides improved UV resistance, weatherability and dimensional stability compared with common engineering filaments, making it suitable for outdoor parts and functional prototypes. The filament is presented in black and is designed to deliver consistent extrusion, good layer adhesion and mechanical strength for components exposed to sunlight, moisture or moderate mechanical load.

Advantages

ROSA3D ASA black offers resistance to ultraviolet light and atmospheric conditions while maintaining structural integrity and surface appearance. It balances stiffness and toughness to support mechanical performance in functional parts, and its thermal properties allow reliable printing with minimal warping when correct settings are used. Consistent diameter and extrusion behavior reduce print failures and help achieve repeatable dimensional results on standard FDM/FFF machines.

Suitable for (tasks / use cases)

• Outdoor housings and enclosures exposed to sunlight
• Functional prototypes and end-use parts requiring weather resistance
• Automotive trim pieces, clips and brackets
• Garden tools, fixtures and mounting hardware
• Any application needing improved UV and chemical resistance over standard PLA

Key specifications

• Material type: ASA thermoplastic suitable for FDM/FFF printing
• Colour: Black
• Mechanical properties: designed for good stiffness, toughness and layer adhesion
• Environmental resistance: UV and weather resistant for outdoor use
• Dimensional stability: low tendency to warp compared with some amorphous materials when printed with recommended settings
• Compatibility: works with standard heated-bed FDM/FFF printers configured for engineering filaments

How to use

Print ROSA3D ASA black on an FDM/FFF printer equipped with a heated bed and a nozzle compatible with engineering filaments. Preheat the nozzle and bed to temperatures appropriate for ASA (refer to your printer and slicer recommendations), enable part cooling conservatively, and use an enclosed build chamber or print in a warm environment to reduce warping. Ensure the first layer adheres well by adjusting nozzle distance and bed leveling. Store the filament in a dry place or sealed container with desiccant to prevent moisture uptake that can affect surface quality and mechanical properties.

Usage recommendations

For best results, print ASA on a heated bed with adhesive or a manufacturing-grade build surface, use an enclosure or maintain ambient temperature to minimize shrinkage, and dry the filament before use if it has been exposed to humidity. Test mechanical and environmental performance on sample prints before final use in safety-critical or load-bearing applications.
