Description:
Sting3d PLA PRO is one kind of composite of PLA, is one of the most widely used materials for 3D printing. extracted and purified from corn grain , Biodegradable, environmentally friendly material, special addition add to make PLA melting lower, bright, Lower viscosity, easy to remove support. It’s molecular weight is uniform distributed. making the molecules in the material more compatible, stable diameter accuracy and printing effect.
Characteristics:
1. Natural white, without adding any brightener;
2, MFI is lower than normal PLA
3, no fall down while surface printing.
4, viscosity low , easy to remove support;
5. The temperature is correct and there is no burr phenomenon;
6, Good toughness not easy break , diameter accuracy +-0.03mm, 100% quality assurance；
7, Wide compatibility. PLA Filament is compatible with 99.99% of the FDM printers on the market.
