View Full Version : 3D Printing Helped Rebuild My Face

Since replicating the first hand gun in a 3D printer, technology has come a long way. Here are three videos which show the progress which has been made.

The first is of rebuilding a face after a disfiguring accident:

The second is of a robust bicycle, made all in one continuous piece.

And the last one is - wait for it - 4D printing. Whatever will they think of next?

I have mixed views about this technology, which looks set to revolutionise fields like manufacturing and medicine, to name just two. But with the threat of even bigger job loss where does that leave the human race in terms of usefulness and fulfilment?

SPARKS FLY: TESTING 3-D PRINTED ROCKET INJECTORS

http://governmentsecrets.com/wp-content/uploads/2014/08/8-29-2014-2-17-55-PM.jpg

Engineers just completed hot-fire testing with two 3-D printed rocket injectors. Certain features of the rocket components were designed to increase rocket engine performance. The injector mixed liquid oxygen and gaseous hydrogen together, which combusted at temperatures over 6,000 degrees Fahrenheit, producing more than 20,000 pounds of thrust.

The additive manufacturing process allowed rocket designers to create an injector with 40 individual spray elements, all printed as a single component rather than manufactured individually. The part was similar in size to injectors that power small rocket engines and similar in design to injectors for large engines, such as the RS-25 engine that will power NASA’s Space Launch System (SLS) rocket, the heavy-lift, exploration class rocket under development to take humans beyond Earth orbit and to Mars.

Wow - the implications are tremendous. I wonder if replicating an item in one piece means no nuts, bolts or screws. They could end up being relics of the past . . . . and all that cussing at Ikea diagrams too :)

This could be a bad thing lol.Ever watch stargate with the replicators.
