It is amazing how quickly 3D printing technology has been advancing. The advancements we have seen from the time Chuck Hull invented the process of stereolithography in 1983 until the early 2000′s, pales in comparison to the progress we have seen in just the last few years. When Chuck Hull invented 3D printing, I’m sure he had no clue that today we’d be printing out sensors and other electronic devices, but that’s where exponential progress has taken us.
