1. CAD & Rapid Prototyping by 3-Dimensional Printing (3DP TM ) Jordan Medeiros Stephanie Silberstein Hannah Yun

2. Three Dimensional Printing  Process under development at MIT  Builds parts in layers from a CAD model  Offers flexibility MIT Three Dimensional Printing Laboratory

3. Project Ideas  Nastic Movement  reversible/repeatable movements in plants  Viscoelastic Structures  stress induced is proportional to the rate of strain in the material  Cellular Solids  lightweight materials with unusual physical properties (strength, temperature, etc.)

4. Main Goals: Success?  “Master” SolidWorks  Development of functional model  Takes advantage of 3-D printing  Development of material with multiple, useful applications  Better understanding of design and fabrication process

5. Why is this a compelling project?  Using 3D printing where regular machining isn’t possible  Exploring modern research fields using novel technology  Nastic movement: Naval applications  Viscoelastic structures: human tissue, Tempur-Pedic ® / memory foam  Cellular solids: honeycombs, metal foams, molecular models

6. What do we still need to learn?  SolidWorks (continuously)  Research conducted in possible project fields  Contact experts in the field  Read pertinent literature  More about the 3DP TM process

7. Risks  Being overambitious  Limitations of resources  Time constraints  Failure to produce a working model  Inability to find practical applications  Possibility of existing materials on market better suited for these applications
