While there are plenty of transparent filaments sold on the market, they typically do not produce transparent prints, but rather translucent ones. The difference between transparency and translucency is in the material’s ability to diffuse light. Diffusion may result from several factors, the most dominant one in our case is the inhomogeneity of the print. Under normal settings, the printer leaves small cavities (bubbles) inside the print. Each cavity acts as a small lens (as it is curved) and scatters the light passing through, obscuring any image standing behind the print and making it… translucent!
