The invention relates to a method and a device for casting three-dimensional structured objects. To provide a device and a method for casting three-dimensional structured objects which are economical and allow for the objects to be produced to be cast in a form in which they can easily be reused or produced, the invention provides for the device to comprise several cores (1; 31, 32) which each have essentially the form of a prism and at least three walls which are parallel to an axis or slightly convergent. The prism shapes and cross-sections are chosen such that several cores (1; 31, 32) can be juxtaposed by their prism surfaces (2, 3, 4) in a substantially tight and space-filling manner. At least part of the prism surfaces (2, 3, 4) presents recesses or casting channels (6, 7, 8, 9) which form a continuous structure when the cores (1; 31, 32) are assembled. As regards the method, the hollow form is composed of several cores with a prism-shaped cross-section in such a way that the prism surfaces lie against each other in a substantially compact and flush manner and the cores substantially fully fill out the casting space provided for, with recesses in the prism surfaces defining the structure to be cast. |
