3D Printing News Alert(For 3D printing a wonder material for the future, graphene)

Posted on Updated on

Graphene is strong, light, thin and flexible. It is the thinnest substance capable of conducting electricity, is an efficient thermal conductor and is optically transparent. Graphene is also more resistant to tearing than steel and is almost impermeable.

For 3D printing a wonder material for the future, graphene.

According to GrapheneCa Head of Business Development David Robles,” Proactive Investors to discuss the technology company that is integrating graphene into the real world using their own environmentally friendly production process.

Robles telling Proactive about the company’s revenue streams and when they are expecting to be profitable.”

According to Hodge,” Adding graphene to plastic composites can improve the tensile strength and stiffness of packaging. Graphene won’t make the material indestructible but it may be possible to reduce packaging size while maintaining the same properties. This has obvious advantages for transporting fragile goods and may also contribute to recycling. Today, recycling plastics degrades the quality of the plastic – it can be recycled an average of three times, but adding graphene to recycled plastics can improve its strength so that it can be recycled many times more. Because they are printed, [the capacitive touch sensors] can be any size or shape and printed in volume.”

According to Chris Jones, technical manager at Novalia, a partner in the EU’s Graphene Flagship, “Our mission statement is to make technology disappear into everyday items.
The ink is supplied by Researchers at the University of Cambridge, University of Manchester and produced by micro fluidization.”

According to Francesca Rosella, co-founder of CuteCircuit, “A dress was designed to illustrate the material’s strength, transparency, and conductivity. The shape and decoration of the dress represent the design of a graphene crystal. We examined graphene under a microscope to see the hexagonal structure and enlarged it to help people understand graphene’s molecular structure.”

According to the TechRadar, “Mobile warming the graphene jacket can also conduct electricity, but creator Vollebak has decided to dampen down this ability to protect wearers. Prototypes of the jacket were so conductive that the wearer could hold a battery in one hand and a light bulb in the other, and have the bulb light up, but Vollebak decided that, although interesting, it was best to play it safe and make the material a little more resistant.”

According to Researchers at Osaka Universities co-author Kazuhiko Matsumoto,” Our biosensor enables highly sensitive and quantitative detection of bacteria that cause stomach ulcers and stomach cancer by limiting its reaction in a well-defined microvolume. They have invented a new biosensor using graphene, which is a material that consists of a one-atom-thick layer of carbon, to detect bacteria like those that attack the stomach lining and that have been linked to stomach cancer. When the bacteria interact with the biosensor, chemical reactions are triggered which are detected by graphene. To enable detection of the chemical reaction products, the researchers used microfluidics to contain the bacteria in tiny droplets that are close to the surface of the sensor.”

3-D print colloidal crystals

Posted on Updated on

 

According to Mechanosynthesis Group, MIT, “Highlights from our publication on direct-write colloidal assembly, a new fabrication process combining principles of self-assembly with 3D printing.3-D print colloidal crystals.”
According to study co-author Alvin Tan, a graduate student in MIT’s Department of Materials Science and Engineering, “If you blew up each particle to the size of a soccer ball, it would be like stacking a whole lot of soccer balls to make something as tall as a skyscraper. That’s what we’re doing at the nanoscale.
If you could 3-D print a circuit that manipulates photons instead of electrons, that could pave the way for future applications in light-based computing, that manipulate light instead of electricity so that devices can be faster and more energy efficient.
According to graduate student Justin Beroz, assistant professor of mechanical engineering Mathias Kolle, and an associate professor of mechanical engineering A. John Hart. For the first time, we’ve shown that it’s possible to build macroscale self-assembled colloidal materials, and we expect this technique can build any 3-D shape, and be applied to an incredible variety of materials. Mr.Hart, the senior author of the paper.”
