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

摘要

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.

主权项

1. A method for manufacturing a three-dimensional object, comprising generating the object by successively solidifying single layers of a liquid or powdery solidifiable building material by the action of an electromagnetic radiation, wherein within a layer, a first pulsed electromagnetic radiation and a second pulsed electromagnetic radiation with a higher frequency than the first pulsed electromagnetic radiation or a continuous electromagnetic radiation is used,
wherein between emitting of the first pulsed electromagnetic radiation onto the building material and emitting of the second pulsed or continuous electromagnetic radiation a time period is provided, during which the building material irradiated with the first pulsed electromagnetic radiation is allowed to solidify.
