Scientists have created a silicon beating heart
Posted by Ian Hale in categories: 3D printing, biotech/medical
The soft artificial heart was created from silicone using a 3D-printing, lost-wax casting technique; it weighs 390 grams and has a volume of 679 cm3. “It is a silicone monoblock with complex inner structure,” explains Cohrs. This artificial heart has a right and a left ventricle, just like a real human heart, though they are not separated by a septum but by an additional chamber. This chamber is in- and deflated by pressurized air and is required to pump fluid from the blood chambers, thus replacing the muscle contraction of the human heart.

New 3D printer is ten times faster than commercial counterparts
Posted by Saúl Morales Rodriguéz in categories: 3D printing, materials
MIT engineers have developed a new desktop 3D printer that performs up to 10 times faster than existing commercial counterparts. Whereas the most common printers may fabricate a few Lego-sized bricks in one hour, the new design can print similarly sized objects in just a few minutes.
The key to the team’s nimble design lies in the printer’s compact printhead, which incorporates two new, speed-enhancing components: a screw mechanism that feeds polymer material through a nozzle at high force; and a laser, built into the printhead, that rapidly heats and melts the material, enabling it to flow faster through the nozzle.
The team demonstrated its new design by printing various detailed, handheld 3D objects, including small eyeglasses frames, a bevel gear, and a miniature replica of the MIT dome—each, from start to finish, within several minutes.
Panellists debate about using technology to enhance human life.

Among the mind-boggling new targets envisioned by the Abu Dhabi Police are sending police officers to Mars on a UAE-built spaceship and setting up the first ever police centre on Mars, among the long-term goals.
Other targets include creating the first ever cadre of astronaut officers to police outer space; foresight future police who will work to prevent crimes; 3D-printed police patrol vehicles and even a police centre; robot cops that speak every language on earth; replacing 50 per cent of the police force with robots, and carrying out half of all policing and security decisions based on data mining and analysis.

Nottingham’s 3D printed helmet ushers in a new era of natural brain scans
Posted by Nancie Hunter in categories: 3D printing, neuroscience, quantum physics
“Room temperature quantum sensors can be mounted directly on the scalp of any subject. This will give us a projected four-fold increase in sensitivity for adults, but the sensitivity could potentially be up to a 15 or 20 fold increase for children or babies.”
A £1.6 million collaborative project between scientists at the University of Nottingham and University College London (UCL) is looking to improve the way we map the human brain. Focusing on the development of magnetoencephalography (MEG), researchers have 3D printed a prototype helmet that may yield quadruple the sensitivity of current MEG devices.

3D printer makes first wearable ‘battery’
Posted by Saúl Morales Rodriguéz in categories: 3D printing, biotech/medical, mobile phones, sustainability, wearables
Imagine printing off a wristband that charges your smartphone or electric car with cheap supplies from a local hardware store.
That’s the direction materials research is heading at Brunel University London where scientists have become the first to simply and affordably 3D print a flexible, wearable ‘battery’.
The technique opens the way for novel designs for super-efficient, wearable power for phones, electric cars, medical implants like pacemakers and more.

Google moon shot stands to give industrial 3D printing a boost
Posted by Klaus Baldauf in categories: 3D printing, finance, robotics/AI, space travel
In what promises to be one small step for space travel, and one giant leap for the next generation of manufacturing, an Israeli startup is planning to land a vehicle on the moon that has crucial parts made using 3D printing technology.
SpaceIL is among five teams vying for Google’s $30 million in prize money to get a spacecraft to the moon by the end of March. One of the startup’s suppliers, Zurich-based RUAG Space, advised turning to 3D printing to manufacture the legs of its unmanned lunar lander. With financial stakes high and a tight deadline, SpaceIL engineers were at first deeply skeptical, according to RUAG executive Franck Mouriaux. They finally acquiesced after a lot of convincing.
