3D Printing: Awesome Tech Making in the 21st Century Cathy Dwyer Information Technology Seidenberg School 1

MakerBot 3D Printer Creates 3D objects one layer at a time 2

What are they saying about 3D Printing? “next great technological disruption” – Economist Jan “new workers are mastering 3D printing, a technology that has the potential to revolutionize the way we make almost everything.” – President Obama, State of the Union Address, Jan

What is 3D Printing? “Additive manufacturing” where you create a 3D object one layer at a time Requires a 3D design created by tool such as auto-CAD Requires material such as plastic that can be melted then put on one layer at a time Moving build platform that draws each layer of a 3D design 4

Create Digital Design 5

Plastic filament is the raw material 6

3D Printer builds product by layering one slice of the design at a time 7

How does it work? “Drawing” a traffic cone mNYo mNYo 8

3D Printing If you can imagine it, you can build it 3D printing lowers cost and eases access to manufacturing Reduces the cost of and decreases the time needed for an innovation cycle Prototype – revise – prototype – revise: this takes days rather than years 16

Innovation Inventors imagine shapes, products, tools 3D printing gives inventors rapid prototyping and modeling Revisions and improvements can be added at a fraction of the cost of “traditional” methods “DIY” – ability to innovate, design, and manufacture has never been easier 17

Your takeaway Why study technology? Driver of innovation and opportunity. Why study in a school of computing? Technology is what we do. At Seidenberg, we do cool things with technology every day. Questions? Cathy Dwyer Information Technology Seidenberg School @ProfCDwyer 18
