A few years ago there were actually two companies trying to manufacture "zblan optical fiber" (which has better light transmission than normal optical fiber) in orbit: Made In Space, and FOMS. Both of their websites are tombstones now, afaik. The former was also attempting 3d printing in space, and was bought by Redwire.

Fascinating tech, but seemed to go nowhere.

There are now several 'manufacturing in space platform' companies, like Varda. It's not enough to just be a platform. There needs to be an actual killer app.
