Sorry this reads as if the founders currently have no clue how eyeglasse frames are made. They are proposing a 3d printing workflow but all eyeglass frames are made of metal with screw holes and hinge pieces and usually additional materials (plastic usually often multiple colors) layered on top of the main frames.

They are not 3d printed and can not be unless you making weird one piece frames.

Anyhow until they switch from solid modelling geometry to CAD I won’t take them seriously and no one else should either.

They are definitely in the fake it to you make it stage and have yet figured out how the real world of consumer products actually are made.

This is just another ThreeJS + LLM with the standard ThreeJS built in exporters.
