Description: Biomaterial, extracted from corn grains, biodegradable, environmentally friendly, hard material, high strength and stiffness, bright surface, good smoothness, no curling or warping during printing. But the support is not easy to remove. Our consumables are composite modified with materials imported from the United States. Enhanced toughness, stability, and cold resistance. Ensure non breakage and stable and flat printing. The diameter of consumables should be controlled within ± 0.03mm to ensure smooth printing. Printing will not be affected by clogging or uneven discharge due to wire diameter issues. And it can be suitable for printing in various climates, such as printing in cold areas of minus 10-20 degrees in the north without being affected. The printing temperature ranges from 190 to 220 degrees Celsius, and the substrate does not need to be heated or heated to 60 degrees Celsius.
