Embodiment Construction

[0033] All figures do not show the invention to scale, but only schematically and only essential components thereof. In this case, the same reference numerals correspond to elements having the same function or a similar function.

[0034] according to figure 1 and 2 By way of example, a device 1 for laser sintering is described as a device for producing at least one three-dimensional object by selectively hardening a building material applied layer by layer. However, the present invention is not limited to this particular method. The present invention is also applicable to other lamination methods such as laser melting, mask sintering, drop-on-powder / dorp-on-bed, stereolithography or similar methods.

[0035] In the description of the present invention an orthogonal coordinate system (x, y, z) is used.

[0036] The device 1 for laser sintering comprises a build platform 2 arranged in the x-y plane, on which a three-dimensional object 3 is produced layer by layer in a known...

Abstract

An apparatus and a method manufacture three-dimensional objects by selective solidification of a build material applied in layers. In order to improve the manufacturing process and in particular to optimize heat input, a heating element is provided that has at least two functional openings. One of the at least two functional openings serves as a material pass-through and another of the at least two functional openings serving simultaneously as a radiation pass-through.

Description

technical field [0001] The invention relates to a device and a method for producing three-dimensional objects by selectively hardening a build-up material applied layer by layer. Background technique [0002] A large number of devices and methods are known from the prior art for the production of three-dimensional objects by selectively hardening building materials applied layer by layer. Mention may be made here, for example, of laser sintering or selective mask sintering. A facility that implements such a layer construction method is also called a rapid prototyping system. Such layer construction methods are used for the production of layer-by-layer components made of hardenable materials such as resin, plastic, metal or ceramic, and for example for the production of technical prototypes. In this case, three-dimensional objects can be produced directly from CAD data by means of additive manufacturing methods. [0003] In such layer construction methods, the construction...
