Embodiment Construction

[0044] Figure 1a with 1b The three-dimensional object 1 in has a first section 2 in the form of a flat plate with a constant thickness, a second section spaced apart from the first section 2 in the form of a straight pipe section with circular inner- and outer diameters A section 3 and a support structure 4 extending between the plate 2 and the pipe section 3 along the entire length of the pipe section 3 . The plate 2 is designed to hold the object 1 on another object, and the tube section 3 is designed to guide fluid flow between its ends. They are therefore functional sections or components, unlike the support structure 4 . The object 1 is preferably a hydraulic distribution system or a component of a hydraulic distribution system.

Abstract

An additive layer manufacturing method is disclosed for producing a three-dimensional object (1) and to a corresponding object. Layers of a powder material are sequently applied to a carrier and irradiated, before the following layer is applied, with a laser beam or particle beam selectively only in the areas of the layer which correspond to the three-dimensional object to be produced. Irradiation occurs such that the powder material in the corresponding areas is locally melted or sintered. The object (1) is provided with a first portion (2), a second portion (3) and a support structure (4) which is arranged between the two portions and used for the connection between the two portions. When the layers are constructed layer by layer, the first portion is constructed before the second portion or the first portion is provided as a separate component, on which the support structure and second portion are constructed. The support structure is constructed in the form of a plurality of support legs (9), which extend from the first portion to the second portion and are connected thereto at their opposite ends and are spaced apart from one another at least along part of their length.

Description

technical field [0001] The invention relates to an additive manufacturing method for producing three-dimensional objects and to a three-dimensional object which can be produced by this method. Background technique [0002] Additive manufacturing methods are increasingly used to manufacture prototypes or finished components very quickly. Unlike conventional manufacturing methods, which involve removing material from a block of material by, for example, milling, cutting, drilling or other machining processes, additive manufacturing methods are constructed directly layer by layer based on the digital description of the object Expected 3D object. This method is also already known as 3D printing or rapid prototyping. [0003] In a typical additive manufacturing method, a thin layer of the powdered material from which the object is to be made is first applied on a support plate, and the powder in the just applied layer is selectively The areas corresponding to the object to be ...
