HP’S 3D PRINTER HITS THE MARKET. “The Designjet 3D is based on Stratasys’s Fused Deposition Modeling (FDM) technology, which turns three-dimensional CAD drawings into tangible prototypes by extruding partially molten ABS plastic in extremely fine layers one atop the other, forming the entire 3-D model in a single piece from the ground up. Designjet 3D will print in ivory-colored plastic only while Designjet Color 3D will print single-color parts in up to eight different colors (we’re not sure why you can’t just put a different hue of ABS plastic in the Designjet 3D).”
