One hacker's view of the last four years in 3D printing and the expansion of DIY culture. It will cover the state of the art then, the state of the art now, and where we imagine we will be in four years. Far will review what technologies succeeded, what failed, and how 3D printing has grown, warts and all. He'll also talk about the growth of hackerspaces in that time and how the changes in these topics tie together to show the growing pains of both hacker-centric movements. He'll also make another round of predictions and discuss where 3D printing and hackerspaces are going next.
