Discover unmatched durability blended seamlessly with sustainability through PurePHA™ Printing Filament (Tea Leaves)! By extracting tea leaves using time-honored methods and integrating them innovatively into PurePHA™ filament, we present a groundbreaking material entirely free of PLA. Experience a sensory revolution that captivates both scent and sight.

Advantages

• Fully Biodegradable Material: The primary filament is composed entirely of PHA, with no PLA, and is fully biodegradable in natural environments, including soil, freshwater, and seawater.
• Innovative Sensory Experience: Traditional extraction of tea leaves is innovatively integrated into the consumables, providing a new sensory and visual experience.
• Unique Luster: The raw material is derived from microbial fat PHA, giving the consumables a unique luster.
• Energy Efficiency: Low printing bed temperature, resulting in low energy consumption.
• No Harmful Emissions: No harmful microplastics are released during the printing process.
• Moisture Resistance: The consumables are not easily affected by moisture, and the support structures are easy to peel off.
• Excellent Heat Resistance: Good heat resistance, capable of withstanding high temperatures up to 100°C.
