1. Keith Wood

2. How it Works…  It breaks down 3D models into 2D layers  layers of fine powder are deposited onto the prototype, followed in turn by a layer of liquid binder.  A sealant is added when the part is complete for strength

3. How it works cont.  The ZPrinter 450 lays down layers between.0035 and.0040 inches thick (.089 to.102 millimeters)  It can build prototypes that are 8 inches by 10 inches by 8 inches in size (20 by 25 by 20 centimeters).

4. Materials  Plaster, corn starch, or resins

5. Cost  The ZPrinter costs $45,000 and the Spectrum Z510 about $73,000

6. Cost  I.T. Strategies projects that vendor revenues from inkjet systems, consumables and services used for rapid prototyping will grow from $78 million in 2007 to $148 million by 2012.

7. Software  The 3D inkjet uses CAD software like inventor and SolidWorks.

8. Speed  Considered the fastest prototyper on the market.  It builds an inch or two an hour

9. AMAZING!!!  You could print relief maps of the ocean floor, prototype products for pitch meetings, model human hearts for research or create architectural models to give construction workers a better visual picture of the design plans.  This technology is even being utilized to create artificial bones

10. Limitations  The prototypes are usually fragile.  The process is still slow  Expensive
