Mercury Systems speeds up PCB manufacturing by replacing a costly injection molded tools with in-house designed and 3D printed versions.

When it comes to turning a raw block of metal into a useful part, most processes are pretty dramatic. Sharp and tough tools are slammed into raw stock to remove tiny bits at a time, releasing the part trapped within. It doesn’t always have to be quite so violent though, as these experiments in electrochemical machining suggest.

Electrochemical machining, or ECM, is not to be confused with electrical discharge machining, or EDM. While similar, ECM is a much tamer process. Where EDM relies on a powerful electric arc between the tool and the work to erode material in a dielectric fluid, ECM is much more like electrolysis in reverse. In ECM, a workpiece and custom tool are placed in an electrolyte bath and wired to a power source; the workpiece is the anode while the tool is the cathode, and the flow of charged electrolyte through the tool ionizes the workpiece, slowly eroding it.

The trick — and expense — of ECM is generally in making the tooling, which can be extremely complicated. For his experiments, [Amos] took the shortcut of 3D-printing his tool — he chose [Suzanne] the Blender monkey — and then copper plating it, to make it conductive. Attached to the remains of a RepRap for Z-axis control and kitted out with tanks and pumps to keep the electrolyte flowing, the rig worked surprisingly well, leaving a recognizably simian faceprint on a block of steel.

A first-of-its-kind 3D-printed concrete bridge has been unveiled in Venice, Italy. The bridge is a demonstration of a new 3D printing method resulting in a structure requiring no mortar or steel reinforcement.

The bridge was developed as part of a collaboration between ETH Zurich and Zaha Hadid Architects’ Computation and Design Group. The unreinforced structure was created by 3D-printing concrete blocks using a novel type of concrete ink produced by a company called Holcim.

“This precise method of 3D concrete printing allows us to combine the principles of traditional vaulted construction with digital concrete fabrication to use material only where it is structurally necessary without producing waste,” explains Philippe Block, a researcher from ETH Zurich.

3D Printing is gaining more momentum and popularity than ever! Designers and architects all over the world are now adopting 3D Printing for the creation of almost all types of products and structures. It’s a technique that is being widely utilized in product design, owing to its simple and innovative nature. But designers aren’t employing 3D printing only to create basic models, they’re utilizing this technique in mind-blowing ways as well! From 3D printed artificial coral reefs to a menacing two-wheeler design with 3D printed bodywork, the scope of this dependable technique is unlimited! Dive into this collection of humble yet groundbreaking 3D printed designs!

Scientists from the University at Buffalo have developed a rapid new 3D bioprinting method that could represent a significant step towards fully-printed human organs.

Using a novel vat-SLA-based approach, the team have been able to reduce the time it takes to create cell-laden hydrogel structures, from over 6 hours to just 19 minutes. The expedited biofabrication method also enables the production of embedded blood vessel networks, potentially making it a significant step towards the lifesaving 3D printed organs needed by those on transplant waiting lists.

“Our method allows for the rapid printing of centimeter-sized hydrogel models,” explained the study’s lead co-author, Chi Zhou. “It significantly reduces part deformation and cellular injuries caused by the prolonged exposure to the environmental stresses you commonly see in conventional 3D printing.”

A team of researchers from the University of Maryland has 3D printed a soft robotic hand that is agile enough to play Nintendo’s Super Mario Bros. — and win!

The feat, highlighted on the front cover of the latest issue of Science Advances, demonstrates a promising innovation in the field of soft robotics, which centers on creating new types of flexible, inflatable robots that are powered using water or air rather than electricity. The inherent safety and adaptability of soft robots has sparked interest in their use for applications like prosthetics and biomedical devices. Unfortunately, controlling the fluids that make these soft robots bend and move has been especially difficult—until now.

The key breakthrough by the team, led by University of Maryland assistant professor of mechanical engineering Ryan D. Sochol, was the ability to 3D print fully assembled soft robots with integrated fluidic circuits in a single step.

As someone with a passionate interest in longevity, transhumanism and biological immortality — I am naturally both excited and optimistic that medical technology will continue to advance in my lifetime — hopefully to the point where humanity has cured or at least greatly mitigated the signs & symptoms of most diseases as well as disabilities, radically expanded human biological lifespan regardless of age, and created a more dignified existence for all as a result of rapid breakthroughs in robotics, AI, automation, nanotechnology, 3D printing and biotechnology — which I hope in turn will largely eradicate poverty, disease, food & shelter insecurity, natural resource scarcity, environmental degradation and income inequality. I know that some of my likeminded friends are far more skeptical that we will ever see outright cures or significant mitigations for major diseases and disabilities — much less radical life extension or perhaps biological immortality in human beings — which are widely available on a commercial basis. They cite their belief that pharmaceutical giants, a plethora of not for profit organizations (i.e., American Cancer Society), and many other allegedly “self-interested parties” supposedly allied with government regulatory bodies — apparently do not want to see diseases or disabilities cured or lifespan significantly extended — EVER — as this would prevent them from earning untold sums selling treatments and supports for such things on a regular ongoing basis (i.e., chemo drugs for cancer, statins for cardiovascular disease, inhaled/oral steroids for lung disease, renal replacement therapy for kidney disease, mobile supports for spinal cord injuries, ect.) They believe that too much money would be at stake, too many jobs on the line and the entire “pharma-medical-academic industrial complex” supposedly at great risk, if actual cures or significant mitigations ever saw the light of day. Some of these friends even cite their belief that fully autonomous, accident proof, self-driving cars will most likely never occur — as it would supposed put the entire auto insurance industry at existential risk as well as deprive law enforcement agencies of a key source of reliable revenue (issuing speeding tickets) This one makes me giggle! 🤭 My friends also believe that radical life extension in human beings — much less biological immortality — would apparently upset the proverbial apple cart — where the “powers that be” are concerned — in terms of everything from the highly lucrative profits which are derived from pharmaceutical sales, old age homes, life and health insurance plans, personal financial services and all of the sales of key products and services associated with the aging process — to macroeconomic considerations such as the long term viability of government entitlement programmes. They believe that government regulatory authorities allegedly working at the behest of the aforementioned self-interested parties will always seek to delay, disrupt or even derail ANY and ALL significant progress into cures/mitigations for disease/disabilities, radical human life extension and/or human biological immortality. Apparently, new biotech start ups which do advance the aforementioned things are allegedly “always aggressively bought out by monopoly capital — with their cures and advances indefinitely suppressed” I personally tend to be more on the positive and optimistic side where these things are concerned — but perhaps these rather pessimistic arguments do have some validity — minus the implied conspiracy theory aspect. Do you think human beings will ever be “allowed” to truly be free from illnesses and disabilities? Will we ever be “permitted” to radically expand our lifespans or even become biologically immortal at some point? Please discuss.

I have already taken a few courses for a master’s in physics at the University of Antwerp and I want to complete it there. In a bachelor’s degree you get a basis of knowledge in physics and quantum physics, but it gets more detailed in a master’s.

The main reason I chose to study physics is because my end goal is to achieve immortality. One of the areas that is important in the study of immortality is physics, but as of yet, there is no mapped out path to achieve it.

In America, at least 17 people a day die waiting for an organ transplant. But instead of waiting for a donor to die, what if we could someday grow our own organs?

Last week, six years after NASA announced its Vascular Tissue Challenge, a competition designed to accelerate research that could someday lead to artificial organs, the agency named two winning teams. The challenge required teams to create thick, vascularized human organ tissue that could survive for 30 days.

The two teams, named Winston and WFIRM, both from the Wake Forest Institute for Regenerative Medicine, used different 3D-printing techniques to create lab-grown liver tissue that would satisfy all of NASA’s requirements and maintain their function.
