Replicators Have Arrived, Paul Spudis, Air & Space
"Of all the wonders depicted in science fiction books and movies, one of the most intriguing is the machine that makes anything that you need or desire. Merely enter a detailed plan, or push the button for items programmed into the machine - dials twirl, the machine hums and out pops what you requested. Technology gives us Aladdin's Lamp. A handy device that will find many uses. We're not quite there yet but crude versions of such imagined machines already exist."

"The ProJetTM HD 3000 3-D Production System offers the option of two modes, High Definition (HD) and Ultra High Definition (UHD), for applications ranging from prototypes and concepts to direct castable models. For direct castable models of fine jewelry and other components, the UHD mode is unmatched in its ability to handle delicate features and produce detailed parts and patterns. For precision models and prototypes, the high speed and exceptional surface quality of the standard HD mode is ideal. Rely on the HD mode everyday for a wide variety of applications including concept development, design verification, form-fit testing, and product presentations."
