Wow, this will be a great solution for the rapidly increasing labor rates especially in masonry work. And also this will save time when developing small items rather than making it with human involvement.

But what about the rebar? Printing walls with what is essentially mortar (since it has no aggregate in the mix) has got to be fragile as anything, in the absence of reinforcing materials.

I think it'll be quite a while before this technology will be able to pass building code requirements (think seismic activity shaking the house down like the Big Bad Wolf).

If successful, this would definitely have a huge impact on the construction industry. It's nice to see someone taking the 3D printing to a whole new level by trusting and utilizing his own engineering skills instead of relying on others.

3D printing with cement will probably not change the construction industry very much until it is able to compete with human production rates. It will have a small niche as soon as the process is working, but that will not affect the majority of concrete construction. One-off custom houses are where it will thrive.BUT all should know that all of Minniapolis regulations demand that all houses look different. There is no such thing as identical row housing in that city. One result id that houses all cost about 40% more than a similar house in a more normal area.

Given the intensely abrasive properties of cement as well as it's tendancy to set up and I wonder about the working lifetime of the cement forming robot. There are certainly quite a few challenges to be overcome before it is a commercial level product.

He should team up with these people.

If you could start making wonderful gothic designs, in cement, you could really update

churches or even amusement parks.

if you have ever seen a wall built with old bottles that would be interesting

to sequence in, if you had a second arm that would emplace old bottles to make

a wall with translucent character.

Cement! Wow. I wonder how this will change the construction industry, or the new construction of houses.

I am glad to see that there are new people working on this besides NASA. Some of us have worked on different approaches or just a form of robotic construction for years without any form of press.

Keep bringing this type of information out to the world.

A Frost & Sullivan study finds that increased cyber attacks are prompting a flurry of innovative protection tools.
Devices and interconnected systems are finding a foothold not only in our homes but in mainstream organizations. Here are three tips to mitigate the risk.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
