Manufacturing process using electrolysis (called EFAB)
, Adam Cohen and a team of engineers at the University of Southern California have done a few more
Layer structure such as 12-
The layer nickel chain shown here has six free-moving links.
The chain is not much thicker than a piece of paper. It is probably the thinnest in the world.
But for the engineers who created it, the most exciting thing about the chain is not its size, but the process used to build it.
EFAB technology can generate any 3-D micro-
A simple device in the automation process.
The EFAB was inspired by the \"rapid prototyping\" business process, which uses the stacking program to build solid objects from layers of several hundred micrometers thick.
The equipment for rapid prototyping is usually plastic, while the EFAB can be made from 5-8 μm or less.
Each layer is high by using-
Speed \"instant masking\" technology, followed by a blanket deposit of metal.
Layers are horizontal and repeat the process after the computer-
The generated schema.
Chemical corrosion off the 3 needed for the sacrifice material to leave-D structure.
Instant masking uses a prefabricated board that deposits materials like a printing machine to make the whole process faster.
Traditional Micro
Manufacturing processes that require customization and expensive clean rooms.
Through mass production, EFAB promises to significantly reduce production by many microscale devices.
