Features EXCELLENT PLA MATERIAL: PLA is less distortion and can print sharper corners. Due to these properties, PLA filament can provide excellent printing results. 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. 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. 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. 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.
