Special high-performance engineering materials
Heat deflection temperature 147 °C, offering excellent thermal stability
This filament has a heat deflection temperature of up to 147°C, ensuring that printed parts maintain structural and dimensional stability even in high-temperature or long-duration work environments. The material resists warping and deformation, making it ideal for industrial parts, mechanical housings, or functional components operating under high-temperature conditions. It guarantees reliability and durability, offering a wide range of applications and meeting the high thermal stability requirements for professional printing needs.
Excellent chemical resistance
The material offers outstanding resistance to chemical corrosion, capable of withstanding most solvents, oils, and chemical media. When printing parts that come into contact with chemicals or industrial components, the model will maintain its strength and appearance over time, showing no signs of degradation or aging. This excellent chemical resistance significantly enhances the filament’s reliability in engineering, laboratory, and industrial applications.
V0-level flame retardant
This filament has passed strict testing and meets the V0 flame retardant standard. Printed parts will quickly self-extinguish upon flame contact, effectively reducing safety risks. Whether used in household, office, or industrial environments, the printed functional parts and components offer both safety and performance. The V0 flame retardant characteristic allows users to confidently apply it in high-safety-demand scenarios, such as electrical housings and electronic device protectors.
Exceptional toughness, prints are impact- and drop-resistant
The material has exceptional toughness, allowing printed models to withstand impacts, compression, and drops without breaking or damaging. Whether for functional mechanical parts, load-bearing structural components, or educational and display models, it ensures structural integrity and long-term reliability. This high toughness gives users peace of mind in practical applications, reducing print failures and material waste while enhancing the utility value of the finished product.
