One of the key challenges in 3D printing transparent objects is the presence of tiny bubbles around extruded plastic, which can disperse light inside the object and make it merely translucent, not transparent. To overcome this challenge, researchers have developed a technique that involves using 100% infill with a rectilinear pattern, decreasing the layer height, adjusting the extrusion multiplier, infill parameters/overlay, and print cooling, and changing the transparency of the infill. This technique has been successfully applied to create high-quality lenses using FFF 3D printers such as the Original Prusa i3 MK3S.
