Video: Strength of Aluminum Metal Matrix Composite Versus Aluminum Alloy
The Aluminum MMC demonstrates a yield strength greater than 1018 steel. Additive opens the way to applying advanced materials such as this.
Here is another video illustrating that an important “hook” for additive manufacturing is the promise to develop and apply new materials. Elementum 3D hung dumbbells from competing hooks to demonstrate the superior strength of its lightweight aluminum metal matrix composite. The company performs additive material development on a machine from EOS, applying a blend of aluminum and ceramic powder to engineer the new material seen here.
What makes a good metal powder for additive manufacturing? Case study data highlights the value of particle size and shape, powder flowability, and bulk density.
How do you choose between these high-performance materials? A conversation with Arkema and Plural AM sheds light on 3D printing with these polymers.
A research organization in Germany is developing a laser beam source that operates with a green light, enabling selective laser melting of a copper alloy.
