PERSONAL MODELER CREATES 3-D PARTS FROM CAD DESIGNS

Jul 17, 1995
Shipments of a device for creating three-dimensional models of objects designed on a computer are to begin this month. The Personal Modeler, developed by BPM Technologies of Greenville, S.C., uses a technique called ballistic particle manufacturing. Spheres of molten plastic measuring 70-75 microns in diameter are fired through a piezoelectric jetting system. The concept is similar to that used by an ink jet printer, but instead of creating letters or graphics on a page, the microscopic bits of plastic solidify into a three-dimensional structure.
