3D Printing a Jet Engine

Using Direct Metal Laser Melting (DMLM) to fuse thin layers of hybrid alloys together, a team of engineers at GE has printed a small jet engine that operates. The 3D Printed Jet Engine – [] These Engineers 3D Printed a Mini Jet Engine, Then Took it to 33,000 RPM – [] Consider it a jet […]

Shape Memory Healing

The ability of a shape memory material to return to its original shape after being deformed was first observed in 1932 in an alloy of Gold and Cadmium (AuCd). Since then, many more shape memory materials have been developed, including metallic alloys and plastic polymers. Self-healing autonomous material comes to life – [] Now, in […]

-3300 – bronze age

By allowing copper and tin to melt together and then solidify, an alloy known as bronze is formed. Bronze is harder than either of the original metals and will hold a sharp edge longer. It was first discovered and used in the Middle East. The ability to produce valuable objects made of metal and the […]
