Open wide, because the robots have eyes on your dental work. South China Morning Post reports that a robo-dentist has autonomously implanted two new, 3D-printed teeth into a woman’s mouth.

The procedure, which appears to have made use of a robot arm from Universal Robotics, was developed by a team from the Fourth Military Medical University and Beihang University. The hardware first orients itself with the patient’s head, and is then programmed with the procedure it needs to undertake. It does a dry run to check that it’s got everything right, before the patient is given an anesthetic and the robot gets drilling. The team says that the robot works to tolerances of less than 0.3 millimeters, and can detect and compensate for movements of the person’s head.

Don’t fancy the idea? Well, bear in mind that it’s hoped the robot will be able to make up for a shortfall in the number of practicing dentists in China, which often leads to unqualified practitioners performing questionable procedures.

Robots still find it difficult to perform delicate actions, like picking up a soft object without causing damage. A new form of synthetic muscle could offer up some major improvements.

A group of researchers from the Columbia University School of Engineering and Applied Science has developed a new type of synthetic soft muscle that can be manufactured using a 3D printer. The material is capable of lifting up to 1,000 times its own weight and boasts fifteen times the strain density (expansion per gram) of natural muscle.

A team from the Universities of Glasgow, Strathclyde, the West of Scotland and Galway have created a device that sends nano vibrations across mesenchymal stem cells suspended in a collagen gel.

The authors of the paper, published in the Nature Biomedical Engineering journal, found that these tiny vibrations turn the cells into a 3D model of mineralised bone ‘putty’. This putty isn’t quite as hard as bone at this stage. That’s where the body comes in.

“We add the bone putty to an anatomically correct, rigid living scaffold, that we made by 3D printing collagen,” says Matthew Dalby, professor of cell engineering at the University of Glasgow, and one of the lead authors of the paper. “We put lots of cells in the body so it has a chance to integrate this new bone. We tell the cells what to do in the lab, then the body can act as a bioreactor to do the rest.”

Cellulose is the most abundant organic polymer in the world. It is the primary compound in the cell walls of green plants, and is typically used to make paper and cardboard.

At the VTT Technical Centre of Finland, a state owned research and development non-profit, scientists have used nano-structured cellulose to make a 3D printable material.

The nanocellulose paste is now in development to make smart-dressings that heal and monitor skin wounds.

(3Ders.org) The rapid advance of 3D printing technology means that hybrid-material wind turbine blades complete with metal mesh inserts are no longer the stuff of imagination. These energy savers with “sci-fi-level” performance could become reality in as soon as two years. Philip Totaro of Totaro & Associates, “The greatest challenge for wind turbine blade structural and manufacturing engineers is to implement the idealized performance and noise mitigated designs of aerodynamics engineers,” explains Totaro. “Limitations of previous generations of manufacturing technology and the reliance on lower cost materials have limited the type of spar/shear web structures which could be utilized.” But 3D printing could be about to change all that, Totaro says.

He is expected to walk again as his body heals, growing healthy new bone around the implanted scaffold — which will eventually dissolve.

For millennials and the generations to follow, the future will differ radically from their parents’ world. Massively powerful digital technologies will bring seismic changes in the lifestyles, opportunities, privileges and choices experienced by young people compared to their parents.

The ‘singularity’ event that scientists talk about in artificial intelligence (AI) — when robots would outsmart human beings in reasoning — has just been moved up, according to a top scientist at HP Inc. The progress in AI and machine learning has been so rapid that scientists have upped the estimate for the ‘singularity’ to happen in 2029 from 2040, shaving off 11 years of development time, says Shane Wall, Chief Technology Officer at HP, who also heads the HP Labs which is at the centre of innovation within the company.

Wall, who was speaking at the HP Reinvent Partner Forum here, said there may be some who watch with fear for that event to happen but taken adequate precautions, this change would bring in much good for everyone — be it in manufacturing, health, innovation or elsewhere. He said AI handles huge amount of data and can discern patterns to take decisions. “Machine learning uses AI and big data to learn and it can find things that no humans can see,” Wall noted.

According to him, already there are massive data farms which are crunching big numbers and there are research labs and companies where machines are taught how to use data to managing things around us. Wall, who joined HP over a decade ago, drives the company’s technology vision and its strategy and helms the innovation community within. According to him, machines have become smart enough to predict failures within a system and 3D manufacturing is a massive revolution in the making. “Already, 3D printing is handling intricate products and in the future this will bring about a disruptive change,” Wall said.
