3D printing showcased at Solid conference in SF

SAN FRANCISCO (KGO) -- These days, one can 3D print just about anything, including a high performance race car.

That's exactly what was on display at the second annual O'Reilly Solid Conference at Fort Mason in San Francisco.

Now in its second year, the conference has doubled in size and drawn big names like Intel and G.E.

The conference has been promoted as: "The only conference that goes beyond the Internet of Things and additionally covers the new hardware movement-the even bigger shift that's driving the IoT and much more."

The three day event, which ended Thursday, provided, in part, an intense interactive experience. It's all about the rapidly changing business of making hardware.

Divergent Microfactories showed off its car of the future -- built in half-an-hour, from a kit full of 3D printed parts.

Here, they're not just talking about manufacturing. They're actually doing it.

"We wanted to give people the experience of what it actually looks like to see where their connected devices come from," said Solid Associate Chair David Cranor.

Another project put together at the conference was an assembly line making a wrist band for conference goers.

It lights up green if the person next to you has interests in common. It's built on a similar 3D printer to what's used for the car.
