If you’re interested in superlongevity and superintelligence, then I have a book to recommend., by Sonia Contera, is a book about the intersection of biotech and nanotech. Interesting and well written for the layman, the book covers some of the latest developments in nanotechnology as it applies to biological matters. Although there are many topics, I was primarily interested in the DNA nanobots, DNA origami, and the protein nanotechnology sections. My interest is piqued in these arenas due to my expectation that DNA nanobots and protein nanobots, as well as complex self-assembled custom nanostructures, are going to be key to some of the longevity technologies and some of the possible substrates for mind uploading that are key to superlongevity and superintelligence. There are also sections in the book on 3D bioprinted organs — progress and possibilities, as well as difficulties.

There is even a section that clearly was written specifically to address a discussion that has engaged my friends, Dinorah Delfin and Dan Faggella. The title is:

FUTURE DEVICES: QUANTUM PHYSICS MEETS BIOLOGY MEETS NANOTECHNOLOGY

Now, some might be tempted to consider that particular combination to be “woo woo”, however, please keep in mind the author’s credentials. Sonia Contera is a professor of biological physics in the Department of Physics at the University of Oxford.

A team of researchers with members from Lawrence Livermore National Laboratory, Wright-Patterson Air Force Base and the Barnes Group Advisors found that controlling spatter during laser-powder bed fusion can reduce defects in metal-based 3D printing. In their paper published in the journal Science, the group describes studying the additive manufacturing printing methodology and what they learned about it. Andrew Polonsky and Tresa Pollock with the University of California, Santa Barbara have published a Perspective piece on the work done by the team in the same journal issue.

As additive manufacturing printing methodologies mature, new materials are being tested to find out if they might be used in 3D printers to create new products. In recent years, this has extended to metals. One such technique is called laser-powder bed fusion (L-PBF). It involves the use of a high-powered laser to melt and fuse metallic powders layer by layer to produce a 3D part. It has been hoped that the technique could eventually be used for aerospace and biomedical applications. But thus far, such efforts have fallen short due to the large number of defects that occur with the process. In this new effort, the researchers have discovered a way to reduce such defects, perhaps paving the way for the technique to finally fulfill its promise.

To better understand why the L-PBF process leads to so many defects (such as undesired pores) the researchers conducted X-ray synchrotron experiments and built predictive multi-physics models to gain a better understanding of what occurs during printing. One of their goals was to better understand how energy is absorbed during printing with powder layers that are only a few particles thick.

Researchers at Zhejiang University of Technology, Tianjin University, Nanjing Institute of Technology and Ritsumeikan University have recently created a soft robotic finger that integrates a self-powered curvature sensor using multi-material 3D printing technology. The new robotic finger, presented in a paper published in Elsevier’s Nano Energy journal, is made of several materials, including a stretchable electrode, polydimethylsiloxane (PDMS), AgilusBlack, VeroWhite and FLX9060.

“Soft robots have the potential to bridge the gap between machines and humans, but it is important for them to ensure a safe interaction between humans, objects and the environment,” Mengying Xie, co-author of the paper, told TechXplore. “Embedded soft sensors are critical for the development of controllable soft robots that can fulfill their full potential in practical applications.”

In their previous research, part of the research team working at Ritsumeikan University developed a fully multi-material 3D printed gripper with variable stiffness that could achieve robust grasping of objects. In this new study, Xie, Zhu and their colleagues drew inspiration from this previous work and set out to create a 3D-printed soft finger with sensing capabilities that could monitor its bending movements.

Believe it or not, 3D printed cars are a reality.

Although you won’t be able to find 3D printed cars at your local car dealership just yet, there are some very interesting concepts out there that do a great job of presenting the possibilities of 3D printing in the automotive industry. They even represent the first steps towards mass-produced 3D printed cars.

Here are 10 of the coolest cars that are 3D printed or contain 3D printed parts. Just keep in mind that most of them aren’t available for purchase.

The Czinger 21C is a 1,233bhp 3D printed hypercar complete with a turbo V8 revving to 11,000rpm, a 1+1 layout and $1.7m price tag. Oh, and the big news is it’s 3D printed. Well, large sections of the chassis are, paving the way for a revolutionary new car manufacturing process that could change… everything. It’s mind-blowing stuff, so let Jack Rix be your guide around California’s Koenigsegg rival.

Shoes will invariably wear out with enough use, but scientists might have found a way to delay the shopping trip for their replacements. A USC team has created a self-healing 3D-printed rubber that could be ideal for footwear, tires and even soft robotics. The effort involves 3D printing the material with photopolymerization (solidifying a resin with light) while introducing an oxidizer at just the right ratio to add self-healing properties without slowing down the solidifying process.

This charming conical flask-carrying robot was created by a 3D printer capable of printing with multiple different materials, at a speed and level of detail that was previously impossible. And in the future it could have some, well, slightly more useful applications…

Researchers at the US Department of Energy (DOE)’s Oak Ridge National Laboratory (ORNL) are developing a nuclear reactor core using 3D printing.

As part of its Transformational Challenge Reactor (TCR) Demonstration Program, which aims to build an additively manufactured microreactor, ORNL has refined its design of the reactor core, while also scaling up the additive manufacturing process necessary to build it. Additionally, the researchers have established qualification methods to confirm the consistency and reliability of the 3D printed components used in creating the core.

“The nuclear industry is still constrained in thinking about the way we design, build and deploy nuclear energy technology,” comments ORNL Director Thomas Zacharia.
