eSUN ASA+ Grey 1.75mm 3D Filament 1KG

Product Description

The eSUN ASA+ Grey 1.75mm 3D Filament 1KG is an enhanced, industrial-grade engineering material engineered for demanding outdoor applications, automotive aftermarket modifications, and heavy-duty functional prototypes. Short for Acrylic Styrene Acrylonitrile, this advanced ASA+ formulation acts as a direct evolution of classic ABS, offering highly upgraded ultraviolet (UV) radiation stability, superior weatherability, and exceptional anti-aging protection. This ensures that your parts maintain their structural load capacities, tensile properties, and uniform grey color profile without becoming brittle, cracking, or fading under continuous exposure to direct sunlight and fluctuating seasonal weather.

This Grey engineering formulation prints with an exceptional, low-gloss professional finish that effortlessly masks surface imperfections. Mechanically, eSUN ASA+ delivers high impact strength, enhanced rigidity, and a high heat deflection temperature of approximately 96°C, making it structurally stable in close-proximity electronic bays and warm automotive interiors. Its advanced formulation offers superior chemical resistance against environmental pollutants and common automotive fluids, making it a preferred option for manufacturing robust exterior machinery housings, drone assemblies, and custom functional brackets.

To achieve maximum inter-layer bonding strength and avoid edge lifting or corner warping on massive footprints, printing this material requires proper thermal management. It is highly recommended to run this filament within a closed chamber system, such as a Voron Trident or an enclosed Bambu Lab printer, to maintain a warm ambient environment. Produced under strict continuous laser feedback loops to guarantee a tight dimensional tolerance of $\pm\text{0.03mm}$, this material ensures stable volumetric extrusion. It is packaged on a robust plastic spool configured for smooth rotation inside automated multi-material dry systems and standard external spool mounts.

Key Features

• Advanced ASA+ Weatherproofing: Provides superior long-term resistance to ultraviolet rays, rain, and heat aging compared to standard ABS and basic engineering plastics.

• Upgraded 96°C Heat Resistance: Features a high heat distortion temperature, ensuring printed parts maintain absolute structural geometry under heavy thermal stress.

• Industrial Toughness & Rigidity: Delivers exceptional mechanical impact resistance and stiff tensile characteristics ideal for functional structural frameworks.

• Strict $\pm\text{0.03mm}$ Diameter Tolerance: Monitored continuously across production runs to guarantee perfectly uniform extrusion and clean outer wall finishes.

• High AMS Compatibility: Specially spooled on a durable plastic rim configured to rotate smoothly inside high-speed multi-material dry boxes.

Applications

• Manufacturing functional automotive components, exterior mirror shrouds, rugged marine brackets, and protective trim elements.

• Engineering outdoor sensory housings, weather monitoring equipment enclosures, and specialized structural drone mounts.

• Creating production-line factory jigs, heavy-duty mechanical linkages, and industrial workspace fixtures requiring high thermal stability.
