Weight：
Low density and lightweight, prints ~27% lighter than PLA for the same model
Compared to conventional PLA materials, this filament has a lower density, reducing the weight of the printed model by approximately 27% under the same conditions. This effectively lowers the overall load, making it suitable for applications that require lightweight materials.
Excellent chemical corrosion resistance
This material has excellent resistance to chemical corrosion, maintaining stable performance even in complex environments, thus extending the lifespan of printed models.
Food contact safe material
Made from food-grade safe materials, it offers higher safety and is suitable for environments with higher material safety requirements (recommended to be used according to applicable regulations for specific applications).
High toughness, resistant to breakage, with superior durability and fatigue resistance
The material features outstanding toughness, making it less prone to breakage, while also offering good durability and fatigue resistance. It is ideal for functional components and high-frequency usage scenarios.
