Filament Elegoo ASA (red) — Filament for FDM 3D printers, Elegoo ASA red

ELEGOO ASA Filament in red is a 1.75 mm thermoplastic filament made from acrylonitrile styrene acrylate (ASA) for FDM 3D printers. It is intended for applications where UV stability, weather resistance and dimensional stability are required. The filament is compatible with a wide range of FDM printers and is targeted at functional parts and outdoor use where PLA or PETG may not provide sufficient long-term performance.

Advantages

ASA offers improved resistance to ultraviolet radiation and outdoor conditions compared with many common filaments. It maintains mechanical properties at higher temperatures, has good impact strength and produces durable, stable prints suitable for functional components. The 1.75 mm diameter supports accurate extrusion and broad printer compatibility.

Suitable for

• Outdoor housings, fixtures and signage
• Functional prototypes and mechanical parts
• Components exposed to sunlight, moisture or moderate chemicals
• Applications requiring higher thermal and dimensional stability than PLA

When it may not be suitable

ASA can be more prone to warping than PLA, so printing large flat parts without a heated bed or proper enclosure may be challenging. It also typically requires higher extrusion and bed temperatures, which can be unsuitable for printers that cannot reach those settings.

Key specifications

• Material: Acrylonitrile styrene acrylate (ASA)
• Filament diameter: 1.75 mm
• Colour: Red
• Intended printing technology: FDM (fused deposition modeling)
• Typical properties: UV and weather resistance, improved thermal resistance, high impact strength

How to use

Load the 1.75 mm filament into a compatible FDM printer. Use manufacturer-recommended extrusion and bed temperatures for ASA and enable a heated bed; an enclosed build chamber is recommended to reduce warping. Adjust print speed, cooling and retraction settings to achieve consistent extrusion and layer adhesion. Allow printed parts to cool gradually before removal to maintain dimensional stability.

What to consider before purchase

• Ensure your printer supports ASA: required nozzle, bed temperatures and preferably an enclosure
• Consider warping: use a heated bed, adhesive surface or enclosure for larger parts
• Confirm red colour and finish meet your project requirements

Usage recommendations

For best results with Filament Elegoo ASA (red), print with a heated bed and reduced part cooling, use an enclosed printer if available, and calibrate extrusion temperature and bed adhesion methods for stable, durable outdoor-grade parts.
