Designing Multi-Materials Objects
Typical constructions are a combination of poured concrete and steel reinforcement. Electronics have wires and insulating materials

Specification Based Design
Design object shapes according to more complex constraints and specification in physics, motion, and other functionality (sound?).
Specification Optimization Model Fabrication

Interactive Design
How to let home users create 3D contents easily and intuitively?
More friendly UIs?
Sketch-based UI Photo based Big data (data driven)

Scale
Large scale 3D printing for architectural construction? The mechanical problem: printers that can print objects larger than themselves? (both in surface area and height)

“Closing the Loop”
Physical simulation of 3D printing? We already have a program that can print itself…
char *p="char *p=%c%s%c;main() {printf(p,34,p,34);}";main() {printf(p,34,p,34);}
A printer that can print itself?
