Embodiment Construction

[0015] When producing three-dimensional objects, for example in so-called "3D printing", there are challenges in controlling the structure of the resulting object. For example, it may be desirable to produce objects with various structural properties that may affect or be affected by the material and / or mechanical properties of the produced objects. It is also desirable to flexibly control the structure of the objects produced. In some cases, it may be desirable to change the structure of at least a portion of the object model without having to redesign or regenerate the object model. Furthermore, it may be desirable to produce smooth controlled transitions between different predetermined configurations of different parts of the object model. For example, a first structure may be defined for a first object part and a second structure may be defined for a second object part. For the transition area between the two parts, a seamless fusion of the two structures might be expect...

Abstract

Certain examples described herein relate to the use of three-dimensional thresholding matrices in the production of three-dimensional objects. In one case, the data values ​​for the halftoned three-dimensional matrix are assigned based on the structural volume coverage representation. In some described cases, the structure volume coverage representation defines probability distributions of at least two different structures that can be used to produce a three-dimensional object. A convex combination of at least two different structures is determined based on the data values ​​represented by the structure volume coverage. Data values ​​can be assigned to the three-dimensional matrix based on the determined convex combinations. The resulting 3D matrix is ​​used in halftoning operations to control the distribution of structures in the 3D object.

Description

technical field [0001] The present invention generally relates to an apparatus for generating a three-dimensional object and a method for generating a three-dimensional object. Background technique [0002] Devices that generate three-dimensional objects, including those commonly referred to as "3D printers," have been proposed as a potentially convenient way of producing three-dimensional objects. These devices typically receive a definition of a three-dimensional object in the form of an object model. The object model is processed to instruct the device to produce the object using at least one production material. These production materials may include combinations of reagents and powder matrices, heated polymers, and / or liquid solutions of production materials. Processing of object models can be performed on a layer-by-layer basis. It may be desirable to produce three-dimensional objects having at least one property, such as color, mechanical and / or structural properti...
