High-Performance Flame-Retardant ASA for Demanding Applications

Spectrum FlameGuard ASA 275 in Bloody Red is a professional-grade filament engineered for applications where safety, durability, and environmental resistance are critical. Combining the well-known advantages of ASA with enhanced flame-retardant properties, this material is ideal for functional parts exposed to heat, UV radiation, and outdoor conditions.

Designed for engineers, makers, and print farms, this filament delivers reliable performance, consistent extrusion, and a clean matte surface finish while meeting higher safety expectations.

Key Features & Benefits

• Flame-Retardant Performance
  Engineered with flame-retardant additives, making it suitable for safety-focused and industrial applications
• Excellent Outdoor Durability
  UV-resistant and weather-stable, ideal for long-term outdoor use without significant degradation
• Strong Mechanical Properties
  High impact resistance and durability for functional and load-bearing parts
• Low Warping (for ASA)
  Optimized formulation improves print stability compared to standard ASA materials
• Professional Surface Finish
  Produces a smooth, matte finish with consistent color in a bold Bloody Red tone
• Thermal Resistance
  Withstands higher temperatures than PLA and PETG, making it suitable for demanding environments

Typical Applications

• Electrical housings and safety components
• Automotive exterior and under-hood parts
• Industrial enclosures and fixtures
• Outdoor signage and brackets
• Functional prototypes requiring flame resistance
• Mechanical parts exposed to heat or sunlight

Printability & Material Behavior

Spectrum FlameGuard ASA 275 is designed to balance performance with usability. While ASA generally requires controlled environments, this formulation improves layer adhesion and reduces warping compared to traditional blends.

• Printability: Moderate to advanced (best results in enclosed printers)
• Bed Adhesion: Requires a heated bed and adhesion aid for optimal results
• Warping Control: Reduced vs. standard ASA, but enclosure recommended
• Layer Bonding: Strong interlayer adhesion for durable parts

Compatibility

This filament is compatible with most FDM/FFF 3D printers that support 1.75mm filament and can reach ASA printing temperatures.

Recommended setups include:

• Enclosed printers for temperature stability
• All-metal hotends for consistent extrusion
• Heated build plates for proper adhesion

Works well with prosumer and professional systems from brands like Bambu Lab, Prusa, Creality (enclosed setups), and other ASA-capable machines.
