Bioengineer reveals the biggest challenge to 3D printing organs

Researchers at Bighamton University are working on a 3D printing process that will allow them to build tissues and organs in a lab. This could save lives as people who need an organ transplant would no longer have to wait for a suitable match to be found.

3D printed garden !

Time to spruce up those boring city rooftops! 3D printed gardens are now becoming a thing of the present! 🙂

Too many city rooftops are barren, grey, and boring. Computer scientist Yuichiro Takeuchi, who works with the Sony Computer Science Laboratories, Inc. is out to change that.Takeuchi has found a way to print gardens filled with herbs and flowers. These gardens can then be planted on rooftops, or pretty much anywhere.

He uses a 3D printer and software that he designed to print yarn encasements that hold plant seeds that grow in to full-fledged plants in just a few weeks. His 3D printing technology can print gardens that conform to any shape you choose be it, triangular, rectangular, or even panda-shaped:

The way Takeuchi’s method works is to first design your shape on a computer. Then you feed that design into the 3D printer, which prints yarn in the shape of your choosing.

Once the 3D printer is finished, an attachment to the printer dispenses tiny seeds into the yarn.

Seed-dispenser attached to 3D printer releases seeds into felt.

Takeuchi’s approach hinges on a method called hydroponics where you grow plants with mineral nutrient material in place of soil. This is how some of those amazing vertical gardens are grown, like this one in France designed by French botanist Patrick Blanc.

Creations like the one above can run commissioners $1000 per square meter. Although it might be less expensive to build one yourself, it takes a lot of time and care. High prices and long hours of manual labor are the two factors that are hindering large-scale adoption and preventing greener cities, Takeuchi told Business Insider in an email interview. But 3D printing could be the key.

“The printing solution takes away much of those hurdles, and also provides a high degree of flexibility (one can print out a garden that fits snugly into any designated space) which hopefully will make hydroponic gardening more attractive for citizen living in dense cities with limited space,” said Takeuchi.

Takeuchi presented his ideas for a greener future last month at the Sony CSL symposium, at New York’s Museum of Modern Art.

Right now, Takeuchi can grow relatively small plants, like watercress and herbs such as arugula and basil. Below is an image of one of the plants he grew in about one month:

In the future, Takeuchi wants to print yarn encasements large enough to grow fruits, vegetables, and trees. His current 3D printer is too slow for that large a scale, but he’s spending the next year on building a bigger, faster printer.

Ultimately, Takeuchi envisions his city of residence, Tokyo, lush with blooming rooftops. Plants have proven to increase productivity in the office and they’re ability to suck up carbon dioxide and output oxygen is one way cities could help mitigate their carbon footprint.

Takeuchi is interested in transforming Tokyo rooftops for another special reason, however:

“Here in Japan we love fireflies (they have a special cultural significance), but as they can only thrive in pristine environments we don’t see them in dense, built-up Tokyo,” he said. “I’m hoping that by installing a number of printed gardens on rooftops and walls throughout Tokyo, I can someday bring back fireflies to my neighborhood.”

Below is a a before and after image of what Takeuchi hopes to achieve, which he presented at the Sony CSL symposium:

3D printed paper airplane machine gun

The sort of 3D printed gun we can all enjoy shooting 🙂

paper airplane machine gun gun

Amid concerns about 3D printed guns, one man has made a prototype of a weapon everyone can agree on: a 3D printed machine gun that shoots paper airplanes.

YouTube user Papierfliegerei fabricated most of the parts for the whimsical weapon using the German 3D printing website fabberhouse.de, and acquired the rest from the Internet and his local hardware store.

The gun feeds paper into it in a flat sheet and folds the paper airplanes itself.
