Researchers use 3D printer to make new materials
Missouri University of Science and Technology scientists are developing additive manufacturing (AM) technology to create improved metals.
According to the researchers, the new materials could be stronger and lighter than conventional ones, which could make manufacturing more efficient and cheaper.
Dr Frank Liou and Dr Jagannanthan Sarangapani received a US$146,758 grant from the National Science Foundation to support their research, which uses AM process modeling, sensor network and process integration.
The structural amorphous metals (SAMs) are made through cyber-enabled additive manufacturing. Researchers us a laser to melt blown powder metal, which is deposited layer by layer to create whatever object is programmed into their computers. The aim is to get the cooling rate correct so that the metal is amorphous, instead of at the natural state of crystalline formation.
Because they’re random, SAMs are reportedly harder, stronger and have more fracture toughness than metals in their natural state. While a crystalline metal will break along its orderly cellular structure, an amorphous metal has no pattern and thus will resist breaking.
Crazy new application of 3D printing.
