3D-printed concrete structure

Posted on Updated on

According to Asst Prof Pham from NTU’s School of Mechanical and Aerospace Engineering, “We envisioned a team of robots which can be transported to a work site, print large pieces of concrete structures and then move on to the next project once the parts have been printed.
This research builds on the knowledge we have acquired from developing a robot to autonomously assemble. But this latest project is more complex in terms of planning, execution, and on a much larger scale.”

Lockheed Martin’s largest 3D-printed spacecraft

Posted on Updated on

According to Lockheed Martin Space executive vice president Rick Ambrose,” Lockheed Martin’s titanium domes are the largest 3D-printed spacecraft parts.
Lockheed Martin has created its largest piece. This titanium domes to cover the fuel tanks of the satellites. The use of additive manufacturing can help satellites assemble faster and with less wasted materials.
Our largest 3D printed parts to date show we’re committed to a future where we produce satellites twice as fast and at half the cost”.

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”.
