Method and device for manufacturing a three-dimensional object that is suitable for application to microtechnology

Abstract

The present invention relates to a method and a device for manufacturing a three-dimensional object, wherein the object is generated by successively solidifying single layers of fluid or powdery solidifiable building material by the action of electromagnetic radiation. The method comprises steps for emitting a first pulsed electromagnetic radiation onto a first area of a layer of the building material, and for emitting a second continuous electromagnetic radiation onto a second area of the layer of the building material.
