3-D diamond printing using a pre-ceramic polymer with a nanoparticle filler |
摘要 |
According to some embodiments, a method includes depositing alternating layers of a ceramic powder and a pre-ceramic polymer dissolved in a solvent. Each layer of the pre-ceramic polymer is deposited in a shape corresponding to a cross section of an object. The alternating layers of the ceramic powder and the pre-ceramic polymer are deposited until the layers of the pre-ceramic polymer form the shape of the object. The method includes heating the deposited ceramic powder and pre-ceramic polymer to at least a decomposition temperature of the pre-ceramic polymer. The decomposition temperature of the pre-ceramic polymer is less than a sintering temperature of the ceramic powder. The method further includes removing excess ceramic powder that the pre-ceramic polymer was not deposited onto. |

1. A method comprising:
depositing alternating layers of a ceramic powder and a pre-ceramic polymer dissolved in a solvent, wherein:
each layer of the pre-ceramic polymer is deposited in a shape corresponding to a cross section of an object; andthe alternating layers of the ceramic powder and the pre-ceramic polymer are deposited until the layers of the pre-ceramic polymer form the shape of the object; heating the deposited ceramic powder and pre-ceramic polymer to at least a decomposition temperature of the pre-ceramic polymer, wherein the decomposition temperature of the pre-ceramic polymer is less than a sintering temperature of the ceramic powder; and removing excess ceramic powder that the pre-ceramic polymer was not deposited onto. |
