This light-powered 3D printer materializes objects all at once

3D printing has changed the way people approach hardware design, but most printers share a basic limitation: they essentially build objects layer by layer, generally from the bottom up. This new system from UC Berkeley, however, builds them all at once, more or less, by projecting a video through a jar of light-sensitive resin.

The device, which its creators call the replicator (but shouldn’t, because that’s a MakerBot trademark), is mechanically quite simple. It’s hard to explain it better than Berkeley’s Hayden Taylor, who led the research:

Basically, you’ve got an off-the-shelf video projector, which I literally brought in from home, and then you plug it into a laptop and use it to project a series of computed images, while a motor turns a cylinder that has a 3D-printing resin in it.

Obviously there are a lot of subtleties to it — how you formulate the resin, and, above all, how you compute the images that are going to be projected, but the barrier to creating a very simple version of this tool is not that high.

Using light to print isn’t new — many devices out there use lasers or other forms of emitted light to cause material to harden in desired patterns. But they still do things one thin layer at a time. Researchers did demonstrate a “holographic” printing method a bit like this using intersecting beams of light, but it’s much more complex. (In fact, Berkeley worked with Lawrence Livermore on this project.)

In Taylor’s device, the object to be recreated is scanned first in such a way that it can be divided into slices, a bit like a CT scanner — which is in fact the technology that sparked the team’s imagination in the first place.

By projecting light into the resin as it revolves, the material for the entire object is resolved more or less at once, or at least over a series of brief revolutions rather than hundreds or thousands of individual drawing movements.

This has a number of benefits besides speed. Objects come out smooth — if a bit crude in this prototype stage — and they can have features and cavities that other 3D printers struggle to create. The resin can even cure around an existing object, as they demonstrate by manifesting a handle around a screwdriver shaft.

Naturally, different materials and colors can be swapped in, and the uncured resin is totally reusable. It’ll be some time before it can be used at scale or at the level of precision traditional printers now achieve, but the advantages are compelling enough that it will almost certainly be pursued in parallel with other techniques.

The paper describing the new technique was published this week in the journal Science.

LittleBits lays off employees as it shifts focus toward education

New York City open-source maker startup LittleBits began to lay off staff last month, TechCrunch has learned. The loss of jobs comes as the company looks to shift more focus toward the K-12 market.

Education-specific offerings have been lucrative for the company in its eight-year existence, but recent products have found the company embracing licensed products, courtesy of its involvement with Disney’s hardware accelerator.

LittleBits confirmed the layoffs as part of an internal restructuring, in a statement offered to TechCrunch.

“The true potential that littleBits provides teachers, parents, and the children is far beyond your standard ‘off the shelf’ gift or toy. In order to have the greatest impact in shaping the next generation of Changemakers, we are prioritizing our business around the K-12 education market,” the company says. “As you can imagine, the education market’s needs are vastly different than that of retail. Given this, we had to re-shape our internal structure, which ultimately led to a reduction in staff.”

It has yet to offer a specific number, but TechCrunch believes the number to be around 15. Not huge in the grand scheme of things, but no doubt a hit to a staff of this size, which numbered around 100, after its acquisition of DIY Co, last summer. That acquisition, LittleBits’ first, will no doubt play a role in the restructuring, going forward.

It’s hard not to see echoes of the difficult decision Sphero made roughly this time last year. The robotics startup went all-in on licensed Disney brands like Star Wars and Marvel, but ultimately pivoted to an education-only focus, after a disappointing holiday season. Education, on the other hand, can prove a lucrative and stable path forward, as schools and districts tend to buy products in bulk. 

Another thing both Sphero and LittleBits have in common is a knack for truly innovative tech products that could do extremely well in the educational space with the right positioning.
