Forging is not typically a term associated with 3D printing processes so was surprising to see when French 3D printing company Prodways recently announced its new technology. While the process does involve metal deposition, can it legitimately be classified as âforgingâ if a hammer or press is never involved? Continue reading “Rapid and Additive, But Forging?” »
Are Ultracapacity Polymeric Supercapacitors viable alternatives to Batteries?
Posted on June 19th, 2017 by Dr. Sina Ebnesajjad
Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS)
The answer depends on whether the recent advances in supercapacitor development help overcome the disadvantages of the capacitance technology, i.e. small amounts of energy storage. According to Dr. Brendan Howlin, at the University of Surrey Department of Chemistry, the ultracapacity supercapacitors have the potential to âopen the door to unimaginably exciting developmentsâ.

‘Spectacles’ Achieve Record Solar Panel Output for Startup
Posted on June 14th, 2017 by Ken Klapproth
When it comes to photovoltaic cells – converting sunlight into electricity – size does matter. But by thinking functionally, a recent startup out of Ăcole polytechnique fĂ©dĂ©rale de Lausanne (EPFL) proves double the output is even achievable with smaller surface areas. Continue reading “‘Spectacles’ Achieve Record Solar Panel Output for Startup” »

3D printing may have revolutionized part design and manufacture, but uses a deposition process sensitive to consistent material delivery. By âlisteningâ to parts during the additive manufacturing cycle, engineers at GE have devised a new method of assuring parts are free from defects and voids which could cause premature failure. Continue reading “GE Patents Have a Novel Ear for Validating 3D Printing Quality” »
