VDA#9 1) Consider the potential of these 3-D machines, what object would you print that could help the world? Why?  The object that I would print out of a 3D printer would be steel. I chose steel because it has the highest strenght to weight the ratio of any building material. It provide for straight walls,square corners,and allows doors to open and close properly. Which can be good to protect ancient objects in the museum. Steel is also fire resistant and the steel causes the fuel to not spread.It also doesn't rot.these are all the reason why steel is benificial to the future.                                                                  2) From a selfish standpoint, what one item would you print for yourself?  Why?  I would print out a small dog . I chose a dog because it is always alert for criminals. Is loyal to its owner. Their also rescue dogs that can help you when your endanger.thaose are the reasobns why I chose a dog for myself.
