Newby question re mirror making

Here's a simple question, can a primary mirror be made out of something other than glass? Considering the problems with making a tool, then grinding the glass and the popularity of cheap 3d printers, would a printed blank work. I realise it would need to be silvered.

Thanks,

Sheldon.
