High Purity - Made with a good base materials to ensure stable and high-quality output. No Bubble - Printing bright and smooth finished product no drawing no blistering. High Precision - The filaments are universally designed and compatible with 3D Printers using 1.75mm diameter filament with a dimensional accuracy of +/- 0.02mm. Good Printing Effect - No warping no wire drawing no plugging. smooth and delicate accurate color. Good quality - Good tensile strength elongation fluidity low shrinkage. Strong toughness not easily broken strong bending. Environmental Friendly - PLA is derived from renewable resources such as cornstarch sugar cane tapioca roots or even potato starch. So these 3D printer filaments are free from potentially hazardous substances.
