Embodiment Construction

[0052] Preferred embodiments of the invention are described below by way of example with reference to the use of a liquid working medium, such as water. It should be emphasized that the invention is not limited to this example, but can also be implemented with a gaseous working medium such as air. Furthermore, it is emphasized that the practical application of the invention is not limited to the geometry of the examples described. Depending on the particular use of the invention, in particular the shape of the container, the arrangement of one and / or more sound source devices and / or the geometry of the sound beam path may be modified.

[0053] Reference is made exemplarily to particulate material, but the invention is similarly applicable to accumulating and pooling material in other forms or mixtures in the form of granules, suspensions of pastes, and / or polymers.

[0054] The figures represent schematic representations only. In a practical implementation, a power supply an...

Abstract

A method of fabricating a component (1) comprises the steps of providing precursor material in a working medium, creating acoustic forces and positioning the precursor material in the working medium under the effect of the acoustic forces, so that a material distribution is formed, which has a shape of the component to be fabricated, and subjecting at least one of the material distribution and the working medium to a fixation, so that the precursor material of the material distribution or the working medium surrounding the material distribution is bound, wherein the step of creating the acoustic forces includes generating an acoustic interference pattern (5), and the material distribution (4) is formed by moving the precursor material (2) towards energy extrema of the acoustic interference pattern (5). Furthermore, an apparatus (100) for fabricating a component (1) is described.

Description

technical field [0001] The invention relates to a method of manufacturing a part having a one-dimensional, two-dimensional or three-dimensional geometry, wherein the shape of the part is obtained by using the action of an acoustic field and acoustic force and by fixing the shape formed in the acoustic field. This can be achieved by accumulating material, such as discrete particles, in pressure nodes formed by the acoustic field. Furthermore, the invention relates to a device for producing components, said device comprising sound source means for forming a sound field which generates a shape by acoustic force, said shape including a shape formed by a distribution of particles, said device Fixing means for fixing the shape of the particle distribution are also included. The application of the invention can be used in the field of manufacturing materials and assembly of materials with arbitrary shapes, eg for rapid prototyping purposes. Background technique [0002] Rapid pro...
