3D printing is all the rage these days, it seems to be capable of pretty much everything, but what about 3D painting? Yeah, GE is experimenting with the technology that it is calling "cold spray" which is capable of slowly building up layers of metal by spraying metal powder at very high velocities.



The process is used to repair worn metal components, which would add years or even decades to their lifespan. 3D printing has limits of the size of the objects it can create, but 3D painting only has one limitation: the spread of its spray. This means that the technology, or spray, could be used to create or repair very large structures, or cars. The process is being looked at as one possible way to repair parts used in oil and gas drilling, which would be perfect as there's no heat involved.


No heat involved means that the chance of a fire or explosion are reduced much closer to 0%.
