Adrian Bowyer posted interesting overview of how 3d printed robot model developed trough time and how the technology advances.It starts with Yoshimi, a 3d printed robot developed by Ed Sells made on expensive Stratasys machine (since RepRap didn't exist at the time) and was wired manually trough internal channels filled with Wood's metal. The process was slow and messy, electric connections were unreliable.

As the technology advances, Adrian updated the robot design which he calls Sells now in honor of Ed. Tho robot can be printed on cheap dual extruder home 3d printer like Ormerod in one go and is internally wired with F-Electric conductive filament.

We are moving in small steps, but we are moving forward! The advancements are obvious in span of few years.
