I'm gonna second CA's sentiment, Aside from some mechanical specifics, the Aether1 is almost the same as the Hyrel System line of printers. The main difference is that the Hyrel SDS heads are direct-drive and the Aether's are pneumatically driven.

Pneumatically driving a syringe leads to very spongy motion, making it practically impossible to prime and un-prime the head accurately. I notice they don't have any videos of it printing or pictures of syringe printed items from it (or any printed items from it for that matter).

Also, claiming that a bike chain driven gantry has a 4 nanometer precision is just hilarious.
