Other than prusa, I'm not sure of any you can purchase. Of the build yourself ones, they are variants of prusa. Or corexy. For a bedslinger, I built a bear upgraded prusa Mk something. But custom, so not exactly. For my next, it will be a variation of a corexy. Smash together a voron and the other popular one. Because I don't like the bed design.

Plenty of open source projects out there, not sure why you would claim otherwise. The biggest is probably Voron, but it's far from the only one- Others that I'm familiar with are RatRig, Positron, the 100, the Micron, and Powerbelt3D, but that's far from an exhaustive list. There's even an SLS project called SLS4ALL.

Nice! Great list, do you run any of them?

My claim was I didn't know of any others. I've seen rat rig and voron. I'm not sure if they are really open source. I tried to contact them last year, but the documentation was locked. I'll favorite your list flow when I get some time. I'd love to build something like my first reprap.

That's fair, I think I misread the tone of your initial comment and got peeved. Voron could very well be the poster child for open source hardware projects and has a huge community around it.

It's definitely strange that you had trouble accessing the voron documentation, it's likely they were just having issues with their site. It can usually all be found at docs.vorondesign.com. RatRig also has pretty solid documentation but it can be a bit harder to find. Afaik it's all at ratrig.dozuki.com.

Hope that helps!
