I don't read the language, but it looks like they cast the transparent parts from a temporary mold I learned a long time ago the wisest thing I can do is be on my own side, be an advocate for myself and others like me. -Maya Angelou

Very strange. I read the language and my understanding is that is is not 3D-printing. It is more laser cuting of different individual layers that are then assembled.
How they go from this set of layers to a transparent part is... unclear.
