High purity and environmentally friendly raw material: no waste and recycled material, no clogging and sufficient extrusion. Low tolerance of filament diameter, better pressure: the tolerance of filament diameter is within ±0.2mm, with better pressure and higher precision Good tensile strength, high quality and great flexibility: good tensile strength, good stretchability, good flow, low shrinkage, good flexibility and light weight No distortion. Better printing: the printed model without deformation and bubbles has a fine surface and colour accuracy Suitable for all 3D printers on the market
