When 3D printing with PLA, you may sometimes want to print objects that are clear or translucent. This is done by using a different type of filament or lens material. Clear PLA filaments are made with additives that allow light to pass through them, while still maintaining the same strength and durability as regular PLA. Translucent PLA filaments have tiny micro-lenses suspended in the plastic, which diffract light and create a frosted effect.
