Use "Download" to get properly formatted slides. Apparently Slideshare has problems with revealing items on a slide... It just puts them all there! The RepRap project is a thriving community that develops an open source 3D printer that fabricates not only arbitrary objects, but also the parts to make more 3D printers. Besides being interesting in itself, the project provides valuable indications of the impact of affordable digital production tools. I will show how a distributed community is enabled to collaboratively develop not only the software but also physical innovations and content, independent of manufacturers. I will also show how a commons of open source 3D content can emerge and how this further lowers the barriers for individuals to innovate and express themselves. It is exciting to see more and more individuals empowered to participate in this expanded scope of open source. Possibly, projects like the RepRap will revolutionize "making" not entirely unlike the PC and Linux have done for computing.

hardware and the future

fabrication
• Science fiction or inevitable?
• Why will it happen?
• How fast will it happen?
• Tension between ease of copying
and obsolete but powerful
industries?
