Julian Leland of Swarthmore, PA, wrote in to share the milling machine he built for his senior project.

I’m a graduating engineering major at Swarthmore College in SE Pennsylvania; I just wrapped up my senior design project this month, and wanted to share it with you.

My project was to design and fabricate a “self-replicating” milling machine. Philosophically, it’s somewhat of a mixture of the RepRap and the Multimachine – create a high-precision metalworking tool, which is made entirely of easily available off-the-shelf components or components that a preexisting copy of the machine could make.

Currently, it’s still at “prototype” level – there’s been some nasty chatter issues that I’m still working out. However, in the meantime, I wanted to post my work to share with the community (and hopefully get feedback, too). Enjoy!
