20230128778 · 2023-04-27 ·

A method for forming a complex shape three-dimensional ceramic article by printing a first layer of a first material having a first fraction of first ceramic particles and a first fraction of a first polymeric ceramic precursor. A second layer is printed such that it is at least partially disposed on the first layer of a second material having a second fraction of second ceramic particles and a second fraction of a second polymeric ceramic precursor. A composite of the first layer and the second layer is heated at a temperature sufficient to decompose the first and second polymeric ceramic precursors and sinter the article. During the sintering process, the first and second layers with different fractions of ceramic particles undergo different degrees of shrinkage, resulting in a tuneable mismatch of the bilayer structure and accurately achieving a targeted geometry.

Method and device for producing a three-dimensional object

A method for producing a three-dimensional object on a support by applying layer by layer and selectively solidifying a building material in powder form. The method includes lowering the support to a predetermined height below a working plane, applying a layer of the building material in powder form in the working plane, selectively solidifying the applied powder layer at positions corresponding to a cross-section of the object to be produced and repeating the steps of lowering, applying and selectively solidifying until the object is completed. By doing so, the quantity of applied building material in powder form is reduced in a section in an actively controlled way or substantially no building material in powder form is applied in a section in an actively controlled way.
