Nebula ASA Kevlar Black 0,8 kg

Nebula ASA Kevlar is a composite technical filament based on ASA (Acrylonitrile Styrene Acrylate) copolymer reinforced with aramid fibers (Kevlar). This combination joins the high weather and UV resistance typical of ASA with the toughness and resistance of Kevlar fibers, making it an excellent choice for long-term stressed functional parts.

The Black version is a universal technical color suitable for industrial components, covers, brackets, and mechanical components where mechanical resistance, stability, and professional appearance are key.

Key Features

• ASA composite with Kevlar (aramid) fibers – significantly higher toughness and resistance to impact and material fatigue.
• High resistance to UV radiation and weather conditions – suitable for long-term outdoor use.
• Low abrasivity compared to carbon or glass fibers – less nozzle wear and lower maintenance costs.
• Excellent dimensional stability – suitable for precise technical and assembly parts.
• Temperature resistance of finished prints up to approx. 100–105 °C (typical for ASA grade 301).
• Matte, technical surface – effectively masks minor layer imperfections, suitable for functional and visual components.
• Designed for printing on FDM/FFF printers with an enclosed or well-covered printing space.

Recommended Use

Nebula ASA Kevlar is particularly suitable for:

• Outdoor parts and covers – sensor holders, electronics covers, urban furniture elements.
• Automotive and moto parts – brackets, holders, strips, assembly fixtures in interior and exterior.
• Industrial and manufacturing fixtures – gauges, jigs, stops, clamping segments.
• Sports and hobby equipment – components exposed to impact, vibration, and weather.
• Technical prototypes – parts where behavior in real, demanding conditions needs to be verified.

Printing Recommendations

Specific values may vary slightly depending on the printer and conditions. Use them as baseline settings and fine-tune based on your experience.

• Nozzle temperature: approx. 250–265 °C
• Bed temperature: approx. 90–100 °C
• Printing speed: medium (e.g., 40–80 mm/s) depending on printer type
• Chamber: enclosed / heated printing space is recommended, especially for larger parts (reduces warping and layer cracking)
• Cooling fan: minimal to moderate – only for fine details, otherwise preferably off
• Nozzle type: standard brass can be used (fibers are significantly less abrasive than carbon or glass), however, for long-term operation, a hardened nozzle is always a safer choice

When printing larger models, it is advisable to:

• use brim/raft for better adhesion,
• limit drafts around the printer,
• print at a stable ambient temperature.

Advantages of ASA Kevlar compared to standard ASA

Compared to classic ASA filament, the version with Kevlar fibers offers:

• higher resistance to impact and fatigue – more suitable for mechanically stressed components,
• lower brittleness under dynamic loading, better behavior under cyclic bending,
• lower abrasivity than carbon or glass fibers – longer nozzle life,
• still high UV and weather resistance typical for ASA.

Technical Parameters

• Material: ASA (Acrylonitrile Styrene Acrylate) composite reinforced with aramid (Kevlar) fibers
• Color: Black
• Filament diameter: 1,75 mm
• Filament weight: 0,8 kg
• Recommended nozzle temperature: 250–265 °C
• Recommended bed temperature: 90–100 °C
• Recommended nozzle type: standard or hardened (for long-term operation)
• Recommended printing space: enclosed / covered, especially for larger parts
• Heat resistance of finished part: approximately up to 100–105 °C (short-term even more depending on part geometry)

Tips for Successful Printing

• Dry the filament before printing (approx. 60–70 °C, for several hours) to remove moisture and improve the surface.
• Use a suitable adhesive agent on the bed (PEI, special glues, ABS/ASA juice) to minimize warp.
• Calibrate the first layer and check bed flatness – ASA is sensitive to corner lifting.
• When printing functional parts, choose higher temperatures in the upper range of recommendations for better layer adhesion.
