Features UNITED WIRE DIAMETER: With uniform filament output, which helps to improve pressure accuracy. The filament is fully compatible with all popular 1.75 mm 3D printers. SMOOTHER PRINTING: Less thread pulling and twisting, minimal shrinkage and strong adhesive layer, as well as less jams and mistakes, and allows smoothing and continuous printing. THERMOCHROMIC COLOR CHANGING: PLA filament is specially designed to change color with temperature. It starts out green and transitions to yellow as it heats up during printing. WIDELY USED: PLA is one of the most commonly used methods for beginners and professionals. It is ideal for mechanical parts, prototypes, models, accessories, etc. and allows faster and easier printing. EXCELLENT PLA MATERIAL: PLA is less distortion and can print sharper corners. Due to these properties, PLA filament can provide excellent printing results.
