MIT News Office posted a survey of the fascinating research at the university, and by alum, on an array of 3D printing technologies and applications.
Another variant underway now is a system being developed by Neri Oxman PhD ’10, the Media Lab’s Sony Corporation Career Development Assistant Professor of Media Arts and Sciences, and her graduate student Steven Keating for “printing” concrete. Their ultimate aim: printing a complete structure, even a whole building.
Why do that, instead of the tried-and-true method of casting concrete in wooden forms that dates from the heyday of the Roman Empire? In part, Oxman explains, because it opens up new possibilities in both form and function. Not only would it be possible to create fanciful, organic-looking shapes that would be difficult or impossible using molds, but the technique could also allow the properties of the concrete itself to vary continuously, producing structures that are both lighter and stronger than conventional concrete.
To illustrate this, Keating uses the example of a palm tree compared to a typical structural column. In a concrete column, the properties of the material are constant, resulting in a very heavy structure. But a palm tree’s trunk varies: denser at the outside and lighter toward the center. As part of his thesis research, he has already made sections of concrete with the same kind of variations of density.
“Nature always uses graded materials,” Keating says. Bone, for example, consists of “a hard, dense outer shell, and an interior of spongy material. It gives you a high strength-to-weight ratio. You don’t see that in man-made materials.” Not yet, at least.
Where are our petabyte drives? Brian Hayes takes us through the reasons storage is “stuck” in the low terabytes. The tl;dr is that we got such exceptional capacity growth in the late 90s and early 00s we don’t need much more right now, so the focus since then has been on SSDs, networking, interfaces, etc, […]
Amélie Lamont, a former staffer at website-hosting startup Squarespace, writes that she often found herself disregarded and disrespected by her colleagues. One comment in particular, though, set her reeling — and came to exemplify her experiences there.

White hat hackers get paid to find holes in their own employers’ online systems, and plug those holes before they become serious security risks. It’s a job that pays handsomely…mostly because few job candidates, even experienced IT professionals, have the skills to scamper over firewalls and infiltrate the deepest recesses of a battle-tested network. But […]
Why buy one of those expensive and confusing universal remotes, clogged with enough buttons to launch a space shuttle, when you could accomplish the same electronic control right on your favorite mobile device? The Blumoo Universal Remote, now just $52.99 in the Boing Boing Store, harnesses the audio power of all your household equipment right […]
You may not love Microsoft Word, but you’ve definitely used it. Other than being one of the most ubiquitous programs on the planet, it’s been the go-to word processing system for more than a quarter-century because it’s as basic as it gets. But occasionally, you’ve got assignments that beg for a lot more options than simple […]
