QU-BD Combo CNC Mill And 3D Printer Pre-Order Interview

I’ve been saying for a while that there’s nothing inherently expensive about 3D printing technology…at least not the FFF type. Assuming the technology becomes more popular over the next few years (which I do) I don’t see any reason why 3D printers couldn’t become as cheap and ubiquitous as 2D printers.

However, 3D printing has weaknesses, not the least of which is that it can’t work in metal.* You can take the plastic parts and cast metal parts from them, but the heat and gases have side effects that nobody in their right mind would ever allow inside a house. It is possible to work metal by machining it in a small CNC mill, as demonstrated by the ease of finding a desktop mill on Google. Since 3D printers and CNC mills function so similarly, why not combine both functions into one machine?

QU-BD is working on that. Openalia interviewed them back when they were coming off of a successful effort to Kickstarter their own thermoplastic extruder. Now they’ve arrived at the main event, the beta Rapid Prototyping Mill (RPM) pre-order. This design is important because it has the potential to create all of the (non-electrical) parts for a 3D printer, including its own extruder. Read through the interview with Chelsea Thompson after the jump to learn a little bit about the RPM and the Revolution, which is an all-metal frame 3D printer.

* I’m limiting the analysis to current technology. Sure, there might be an unforeseen breakthrough in materials science in the near future, but that’s a different discussion.

Printable Folding Construction Demonstrated With Robots

Sometimes you just can’t get from where you are, to where you want to be, in one step. For example, open hardware tends to work with stock materials, which means flat sheet is popular. It’s usually cheaper to obtain and work than a large block of the same material. But there aren’t very many ways to use a flat sheet if it stays a flat sheet. A couple popular ways to fold a flat sheet into a useful volume are illustrated.

Can this folding idea be taken even farther? For example, can we fold flat surfaces not just into structures, but into mechanisms as well?
