Hello, My question is regarding material thickness and translucency. I have drawn a sign in Solid Works which has raised letters. I want to back light the letters with LEDs so they stand out. I initially set the wall thickness at .005". After doing some reading this is probably not printable. I have sent a message to William the materials engineer and thought this would be a good place to ask as well. I plan on using WSF for the sign. Is there anyone with experience or knowledge of a project? At what thickness is the material not able to pass light. Thanks.
