3D-Printed Acoustic Levitator

Ultrasound researcher Asier Marzo has managed to 3D-print a levitator capable of levitating liquids and solids in mid-air using acoustic waves. He lined both ends with 72 transducers, connected them to an Arduino board, and then when 6-10 volts are run through them, it generates sound waves at a frequency of 40 kHz. Those sound waves can support objects in mid-air, while levitating the liquids require lower voltage. Click here to view the first image in today's viral picture gallery.

Bugatti 3D-Printed Brake Caliper

Bugatti doesn't mess around when it comes to hypercars, and all of their current offerings not only cost millions, but are the fastest on the road. The automaker decided to take things one step further by rethinking the manufacturing process, and in the process of doing so, recreated the world's first caliper produced using 3D printing technologies. It's made entirely from titanium, the same material used in the SR-71 Blackbird jet. Bugatti teamed up with Laser Zentrum Nord for the production process, which utilized 2,213 layers of titanium powder fused together by four high powered lasers over 45-hours.

Modern Day Protector

3D printers can now be purchased for less than $200, so it's no surprise that more artists are incorporating the into their work, like Garret Kane. His latest project is called "Golemecha" (combination of two words: Golem - a protector made from mud and sticks from Judaic folklore - and Mecha - a protector made from advanced robotics in the Japanese culture), which is basically a modern-day protector. It was created using 3D-printed parts, some preserved moss, lots of wire mesh, an array of LED lights and other materials. Continue reading for more pictures.

3D-Printed Nerf Gun

Nerf blasters come in all shapes and sizes, but for a truly DIY feel, there's no better feeling than 3D-printing your own. That's exactly what "OutofDarts" did with his creation, called "Sylphrena", which is essentially a fully automatic Nerf Rival-style blaster that holds 65 rounds and features a simple flip top cap for reloading on the fly. It utilizes a brushless blower, flywheels and a pusher wheel to feed the balls. Click here to view the first image in today's viral picture gallery.

3D-Printed Heart

Researchers from Swiss technology institute ETH Zurich have 3D-printed an artificial heart that could one day become a transplant for patients in need. It was made from silicon using a 3D printer, and looks as well as functions just like a real human heart. The 390 gram heart has a left and right ventricle separated by an additional chamber inflated and deflated with air pressure, similar to the pump action of the human heart. "This was simply a feasibility test. Our goal was not to present a heart ready for implantation, but to think about a new direction for the development of artificial hearts," said researcher Nicholas Cohrs.

3D-Printed Honda Motorcycle

New York-based artist Jonathan Brand has always wanted a 1972 Honda CB500, but instead of scouring the classifieds, he used open source Ultimaker 3D printers to create a replica of the motorbike from PLA plastic. In other words, each individual component of the bike was modeled in a 3D program before they were printed. Continue reading for more pictures and information.

Paul Kohlhaussen, a Richmond student, decided to create a fully-functional 3D-printed camera, when he realized his dream cameras were way out of his budget. Even more impressive is the fact that he had no prior knowledge in CAD software, and managed to teach himself everything from scratch. This custom-built creation combines the features of the Mamiya 7 (medium format photography), Hasselblad XPan (panoramas), and last, but not least, the Leica M Series. What he ended up with, is the "Cycloptic Mustard Monster," which is designed to shoot 6 x 14 negatives on 120 film, and features an 8-part modular design that easily pairs with camera gear.

Solar 3D Printer

MIT researchers have just created a solar-powered robot that can 3D print the entire basic structure of a building using on-site materials. A user could customize the structure any way they see fit, thanks to a vehicle with one large robotic arm with a second smaller and more precise arm at the end. The vehicle also comes equipped with a scoop, so that it can help prepare the building area and pick up building materials on its own. They recently showcased the technology by building a 12-foot high, 50-foot wide dome out of foam-insulation framework, in just 14-hours.

Self-taught artist Melissa Ng unveils her latest project, "Sovereign Armor," which took over 518-hours to complete, and that's without the 3D-printing process. Weighing in at 8-pounds and equipped with glowing LEDs, the intricate patterns you see "are meant to look like rolling waves while the fluting is meant to look like ripples," said the artist. The glow was designed to "give the impression of magical and ethereal energy and symbolize the light of the creative," adds Ng. Continue reading for more pictures and information.

3D-Printed Grenade Launcher

Created by the U.S. Armament Research Development and Engineering Center (RDECOM), this 3D-printed grenade launcher, called "RAMBO" (Rapid Additively Manufactured Ballistics Ordnance), is functional and made from aluminum using a proprietary direct metal laser sintering process. It took the team approximately 6-months to design and manufacture this weapon, with 3D-printed ammunition thrown in. Click here to view the first image in today's viral picture gallery.
