Heat Deflection Temperature of 147°C, providing exceptional thermal stability
This filament features a heat deflection temperature of up to 147°C, allowing printed parts to maintain excellent structural and dimensional stability even in high-temperature or long-term working environments. Whether used for industrial components, mechanical housings, or functional parts operating under elevated temperatures, the material ensures reliable performance and durability. It provides a wider range of application possibilities and meets professional printing requirements where high thermal stability is needed.

Excellent Chemical Resistance
The material offers outstanding chemical corrosion resistance and can withstand the effects of most solvents, oils, and chemical media. When printing components or industrial parts that come into contact with chemicals, printed models can maintain their strength and appearance stability over long periods without degradation or aging. This excellent chemical resistance greatly enhances the reliability of the filament in engineering, laboratory, and industrial applications.

V0-Level Flame Retardancy
The filament has passed strict testing and meets the V0 flame retardant standard. Printed parts can quickly self-extinguish when exposed to flames, effectively reducing safety risks. Whether used in home, office, or industrial environments, functional parts and components can achieve both safety and reliable performance. The V0 flame retardant property makes it suitable for high-safety applications such as electrical housings and electronic equipment protection components.

Extreme Toughness, highly resistant to drops and impacts
The material features outstanding toughness, allowing printed models to resist cracking or damage when subjected to impacts, compression, or drops. Whether used for functional mechanical parts, load-bearing structural components, or educational and display models, it maintains structural integrity and long-term reliability. The high toughness provides greater confidence in practical applications, reduces printing failures and material waste, and improves the overall value of finished products.
