A METHOD AND A SYSTEM FOR LAYER-WISE AND PATTERN-WISE CONTROLLED APPLICATION OF PARTICULATE MATERIAL ONTO A RECEIVING UNIT

摘要

A new process for printing or construction of 3-dimensional objects comprises a pattern-controllable application, possibly in several successive layers, of a particulate material onto a receiving unit from a semiconductor die having memory elements and control logic circuitry and which constitutes a pattern matrix which is controllable regarding information, and which pattern matrix comprises a plurality of small capacitor plates which by means of electrical fields temporarily hold particulate material which has been sprinkled in.
