Abstract
The dimensions of objects produced by means of layer-structuring methods keep increasing while said objects get heavier and are thus less easy to handle and transport. Fine structures can even break off the whole body as a result of the intrinsic weight thereof. The aim of the invention is therefore to create a layer-structuring method for producing a three-dimensional object as well as suitable material systems which improve the manageability and transportability thereof without imposing substantial restrictions regarding the variety of selectable materials and the stability of the components. Said aim is achieved by using particles that contain at least one cavity, whereby the solid body volume and thus the weight is reduced compared to massive particles without substantially reducing stability.
