Benefits of technology

[0010]By such a method and device, three-dimensional components with enhanced density may be produced, and the mechanical properties of the manufactured component may be improved correspondingly.

Problems solved by technology

The parts producible by the known method, in particular metal parts, however, have a residual porosity, for which reason they are not suitable for certain applications in the microtechnology field.

Embodiment Construction

[0013]Referring now to FIG. 1, a laser sintering device comprises a frame 1, which is open towards the top and has a platform 2 arranged therein that is movable in a vertical direction. The platform 2 is adapted to carry the three-dimensional object 3 to be manufactured. The frame 1 and the platform 2 define inside a building space. The platform 2 is connected to a lifting mechanism 12 that moves the platform 2 in a vertical direction so that the layer of the object 3 that is to be solidified is arranged in a working plane 4, respectively.

[0014]Furthermore, a coating device 5 for applying a layer of a powdery building material 3a is provided. Regarding the building material 3a, any laser-sinterable powder or powders may be used, such as polymers, for example, polyamide and / or polystyrene, metals, ceramics, compound materials and in particular high temperature plastics such as for example PAEK (polyaryletherketone). Regarding metal-containing powder material, any metals and their all...

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of copending application U.S. Ser. No. 13 / 032,283, filed on Feb. 22, 2011, which claims under 35 U.S.C. §119(a) the benefit of German Application No. 10 2010 008 960.5, filed Feb. 23, 2010, the entire contents of which are incorporated herein by reference.BACKGROUND[0002](a) Field of the Invention[0003]The present invention relates to a method and a device for manufacturing a three-dimensional object. The manufactured object is in particular suitable for application in the field of microtechnology.[0004](b) Description of the Related Art[0005]EP 0 758 952 B1 describes a known method and device for manufacturing a three-dimensional object, where the object is generated by successive solidification of single layers of a liquid or powdery solidifiable building material by action of electromagnetic radiation. Here, the electromagnetic radiation is preferably a pulsed laser radiation. DE 100 28 063 A1 and DE 10...
