Implantable micro-devices may one day help regenerate nerves in humans, but for now they are limited by several factors. One limitation is the processing methods used for making the micro-devices, which sometimes require etching patterns into the biodegradable materials. Shoachen Chen is helping medical equipment designers develop micro-devices by improving the processing of biodegradable materials. The Iowa State University professor of industrial and manufacturing systems engineering uses lasers for producing micro-features on polymer surfaces. He is carving out answers to questions about how lasers remove materials from polymers. His work, funded by the National Science Foundation, is important to understanding how designers integrate materials into biodegradable micro-devices.

MIT students modified a 3D printer to enable it to print more than one object and print on top of existing printed objects. All of this was made possible by modifying a Solidoodle with a height measuring laser.
