Using this Sunlu High - Speed PLA Filament is easy. First, make sure your 3D printer is compatible with 1.75mm filaments. Load the filament into the printer following the printer's instructions. Set the appropriate temperature for PLA material in your printer settings. When printing, keep an eye on the process to ensure smooth extrusion. As for storage, keep the filament in a dry and cool place to prevent it from absorbing moisture. If the filament gets wet, you can dry it in an oven at a low temperature for a few hours before using it again. And always handle the filament gently to avoid breakage.
