Injection molded would probably mean the mold is reusable where in this case, it is not. Maybe injection filled?

This seems awful. The inflatable form is not reusable.

Well concrete is not waterproof (generally) so they are technically also using the form as waterproofing. It's pretty clever IMO but you'd need rebar at the very least for any structure worth building...

Pneumatic casting?

It seems like a high amount of complexity. Lots that can go wrong.

I’ll take tyvek and wood :)

Insulation might be nice once it gets chilly.

Concrete construction without rebar is more durable and worth bringing back.
