20150053291 | METHOD FOR MANUFACTURING A FLUID ROUTING COMPONENT BY LAYER-WISE BUILDUP - A method for manufacturing a fluid-leading component includes positioning a base element machined by a material-removing method with a planar upper face in a mounting support. The method at least includes the initial application of a layer section with predetermined dimensions of a particulate material in a predetermined region on the planar upper face of the base element; the heating of the layer section by a heat source in such a manner that the particles of the material within predetermined dimensions bond; and the application thereto and heating of at least one further layer section with predetermined dimensions of a particulate material in a predetermined region. In this way it is possible, in the generative manufacturing method, to obviate the need to provide support structures that subsequently have to be removed, and the base element is a functional part of the component to be manufactured. | 02-26-2015 |
