Self-introduction

Hello， My name is Yi Liu and I'm a senior at Penn state majoring in Industrial engineering.

I start to build things by myself when I was very young. Started from a ring-bell to an electronic ring-bell and now to a

ring-bell software. To me, 3D printers are just amazing, the best tool to turn imagines in your mind in to actual objects, not

only because its the easiest way but also the most efficient way. The even better news is, this tool self-replicating.
