3D print materials and products with superconducting properties is truly a breakthrough towards the mass production of various complex materials. I see this as a large step forward for 3D and placing things on an evolution track to even mass produce synthetic diamonds.

3D printing is revolutionizing many areas of manufacturing and science. In particular, 3D printing of metals has found novel applications in fields as diverse as customized medical implants, jet engine bearings and rapid prototyping for the automotive industry.

While many techniques can be used for 3D printing with metals, most rely on computer-controlled melting or sintering of a metal alloy powder by a laser or electron beam. The mechanical properties of parts produced by this method have been well studied, but not enough attention has focused on their electrical properties.

Perfect; I actually was thinking about robots as personal trainers and sparring partners for boxers. I love boxing as a workout and had thought about having a robot as a sparring partner as well as my weight/ strength training.

BTW — another concept is to build into the weight training machines AI technology to assist users. Think about if the machine sensors that the users’ muscle is about to strain that the machine takes the weight off or lightens the weight on the user of the equipment. And, if the machine senses that the person is about to have an heart attack, etc. that the equipment contacts 911, etc.

Trials of a prototype robot for sports therapy have just begun in Singapore, to create a high quality and repeatable treatment routine to improve sports recovery, reducing reliance on trained therapists.

Researchers at Case Western Reserve University have combined tissues from a sea slug with flexible 3D printed components to build “biohybrid” robots that crawl like sea turtles on the beach.

A muscle from the slug’s mouth provides the movement, which is currently controlled by an external electrical field. However, future iterations of the device will include ganglia, bundles of neurons and nerves that normally conduct signals to the muscle as the slug feeds, as an organic controller.

The researchers also manipulated collagen from the slug’s skin to build an organic scaffold to be tested in new versions of the robot.

The researchers have found a way a hacker can create sub-millimeter defects between printed layers that can create fatigue in the product.

California’s space technology company Made In Space, currently preparing their second zero gravity 3D printer called the Additive Manufacturing Facility for the International Space Station, will be playing a key role in a NASA project that could completely revolutionize manufacturing in space. They will be partnering with Northrop Grumman and Oceaneering Space Systems on Archinaut, a 3D printer capable of working in the vacuum of space that will be equipped with a robotic arm. Archinaut is scheduled to be installed on an external space station pod and will be capable of in-orbit additive manufacturing, the fabrication and assembly of communications satellite reflectors or the repair on in-orbit structures and machinery.

Matthew Davis’ Arcus is officially the most impressive thing we’ve ever seen come out of a 3D printer. Sure, cheap prosthetics and replacement body parts are important uses of the technology, but this spinning rubber band blaster is what finally makes us want to put a 3D printer on our desks.

Unlike most rubber band blasters that only fire a single shot every time you squeeze the trigger or require a drive mechanism to make them fully automatic, Davis’ Arcus uses the energy from the loaded elastics to spin the barrel and automatically fire shot after shot until it’s empty. Brilliant.

With more than 25 years of using 3D printing technology, there probably isn’t a global automotive manufacturer that has pushed the limits of using additive manufacturing applications than the BMW Group. For most of the quarter-century that they have been using 3D printing, it was primarily used in the production of prototypes or one-off custom parts. However BMW began using 3D printing technology to produce end-use parts in series production back in 2012 with their new Rolls-Royce Phantom. Over the next several years, more than 10,000 3D printed components would end up being used to manufacture each Phantom coupe that came off the assembly line. The switch from traditionally manufactured parts to 3D printed parts was so successful that BMW began incorporating them into the new Rolls-Royce Dawn this year.

Pretty cool.

Ready for some buzzword salad? David Gewirtz combines OctoPrint with OctoPi on the Raspberry Pi to drive his LulzBot Mini 3D printer. It’s actually harder to say than to do. Read on to learn how.

3D printers can churn out toys, clothing and even food. But the technology also shows potential for use in industrial sabotage, researchers warn.

Imagine a car maker using 3D printers to manufacture components, only to have the parts contain defects that are undetectable until it’s too late.

A hacker with access to the 3D printers could make that happen, a team of researchers wrote in a recent paper. This could result in a “devastating impact” for users and lead to product recalls and lawsuits, said New York University professor Nikhil Gupta, the lead author of the paper.
