3D printing at scale will bring huge change to many industries including “construction”. We are already seeing this in the machining industry where replacement or repair parts can be printed immediately.
It’s a long way from perfect but its getting better by the month and history will most certainly recognize this as one of the biggest technological advances of this century.
You can probably 3d print nuclear bombs...
I believe they are printing human bone scaffolding for repair of crushed bone injuries. And liver tissue....
We use 3D printing at work to prototype different packaging configurations.
Then we choose the best option and have molds made for injection molding.
