Excellent 3D printer imitation metal wire! Unique metal formula (PLA/PHA + metal powder) allows you to print very similar metal works! Post-treated with sandpaper and steel velvet, your 3D printed product will have a metallic sheen and look just like it was cast. This 3D printing material is about three times heavier than the general PLA so that your 3D printing products have the same texture as the appearance in quality!
