Prof. Lab ASA Black 1 kg

Professional filament Prof. Lab ASA Black is designed for users who need dimensionally stable and long-term durable prints for use outdoors and in demanding conditions. ASA (Acrylonitrile Styrene Acrylate) is a material very similar to ABS, but with significantly better UV stability and weather resistance.

Main benefits of ASA material

• High UV and weather resistance – suitable for parts permanently exposed to the sun and outdoor conditions.
• Excellent mechanical strength and toughness – suitable for functional, mechanically stressed components.
• Better dimensional stability than ABS – lower tendency for warping with correct print settings.
• Heat resistance – suitable for parts exposed to higher temperatures (e.g., in car interiors or near engines and electronics).
• Matte technical surface – black ASA gives prints a professional look, hiding minor imperfections and layers.

Typical use

Prof. Lab ASA Black is ideal for:

• Automotive parts – brackets, mounts, covers, interior and exterior elements.
• Electronics housings and boxes – especially for outdoor sensors, camera systems, and IoT devices.
• Garden and construction accessories – hooks, mounts, hose holders, fasteners.
• Technical and functional prototypes – parts exposed to mechanical stress and temperature changes.
• Outdoor signs, labels, and information boards – where sun and rain resistance is important.

Recommended print settings

Specific values may vary depending on the printer, color, and environment. Take them as initial recommendations and fine-tune them with test prints if necessary.

• Nozzle temperature: approx. 235–260 °C
• Bed temperature: approx. 80–100 °C
• Print speed: approximately 40–80 mm/s (lower speed for high-quality and technically accurate parts).
• Cooling: 0–30 %, ideally low or off for better layer adhesion.
• Enclosure: recommended, especially for larger models to minimize warp and cracking.
• Bed surface: textured or smooth PEI, glass with suitable adhesive (3DLAC, glue stick, etc.).

Printing tips

• For large parts, use a brim or raft to increase bed adhesion.
• Store filament in a dry place – low humidity improves surface quality and minimizes stringing.
• For long, slender parts, choose a higher bed temperature and potentially a printer enclosure to prevent deformations.

Compatibility

Prof. Lab ASA Black filament is compatible with most FDM/FFF 3D printers that can handle technical materials with higher nozzle temperatures and have a heated bed, e.g.:

• Prusa i3 / MK series
• Creality Ender / CR series
• Anycubic, Artillery, Voron, Bambu Lab and other similar printers

Summary

Prof. Lab ASA Black 1 kg is the right choice for anyone looking for a reliable and durable technical filament for outdoor and functional parts. It combines the strength and toughness known from ABS with higher UV stability and better weather resistance, making it ideal for long-term use in exteriors and demanding operating conditions.

Key features:

• Technical ASA filament in black color for outdoor and functional parts.
• High UV and weather resistance – ideal for exterior use.
• Excellent mechanical strength and toughness, suitable for stressed components.
• Better dimensional stability and lower warping than standard ABS.
• Matte technical surface that hides layers and provides a professional look.
• Compatible with a wide range of FDM/FFF 3D printers with a heated bed.
• Suitable for automotive, electronics housings, garden accessories, and technical prototypes.
