Hierarchical 3-D Printing of Nano porous Gold

Posted on Updated on

According to Chris Spadaccini the director of LLNL’s Center for Engineered Materials and Manufacturing, “There are a whole lot of scientific and engineering challenges left, but it could have the significant impact, scaling up should be easier with small-scale reactors because you can parallelize. You could have an array of small 3-D reactors together instead of one large vessel enabling you to control the chemical reaction process more effectively. The Monolithic nanoporous metals, derived from dealloying, have a unique bicontinuous solid/void structure that provides both large surface area and high electrical conductivity, making them ideal candidates for various energy applications”.

US Marines construct 3D-printed concrete barracks

Posted on Updated on

US Marines construct 3D-printed concrete barracks in U.S. Army Engineer Research and Development Center in Champaign, Illinois.

According to the Marine Corps Capt. Matthew Friedell, AM project officer in MCSC’s Operations and Programs/G-3,” the team used a design model on an old computer, concrete, and a 3D printer. The concrete was then put through the 3D printer. It took approximately 40 hours to complete the barracks hut. If there was a robot to do the mixing and pumping, the building could easily be created in one day. This capability would enable a great partnership with the local community because it is low cost, easy to use, and robotics could print the buildings.”

World’s first medium/large-scale 3D thermoset printer

Posted on Updated on

World’s first medium/large-scale 3D thermoset printer installed at ORNL in partnership with Magnum Venus Products.

According to the Bob Vanderhoff, CEO Magnum Venus Products and Moe Khaleel, ORNL Associate Laboratory Director for Energy and Environmental Sciences,“ Thanks to this innovation, research and development managers will be able to prototype faster and bring products to market faster.
Procurement departments will also enjoy shortened lead time on crucial molds – allowing for rapid deployment. This was made possible through ORNL slicing software that allows the integration of multivariate print process parameters.
We’re pleased to collaborate with MVP on this state-of-the-art printer and look forward to seeing the technology continue to progress and positively impact the additive manufacturing industry.
This collaboration is important for accelerating the pace with which new technologies can be successfully commercialized, leading to a larger range of applications and performance criteria for additively manufactured components, while creating new jobs and increased prosperity in our region.”
