Design is a plan for arranging elements in such a way as best
to accomplish a particular purpose - Charles Eames Design
Experience 3D Printing experience o Tolerances o Design vs.
Manufacturing
Slide 27
Environmental Issues No machinery required with 3D printing
Small impact with discarded designs due to small size Recyclable
material
Slide 28
Economic Aspects and Impact Increase in testing expands the
application of materials Industries advance
Slide 29
Global Awareness World-wide pursuit of increasing testing
results Global research Improving technology for the world
