Ceramic feedstock for molten barrier layers and support structures used in additive manufacturing
The invention relates to a ceramic raw material comprising components a), b) and optionally c), component a) being at least one ceramic material, component b) being at least one binder (B) and optionally component c) being at least one additive (A). The ceramic feedstock is preferably provided in the form of filaments for use in three-dimensional (3D) printing techniques, in particular in FFF printing processes. Therefore, the ceramic raw material can be successfully used for 3D printing of a supporting structure and/or a separating layer. The invention further relates to such three-dimensional objects, in particular three-dimensional green bodies, three-dimensional brown bodies or three-dimensional sintered bodies, and to a method for the production thereof.
本发明涉及一种包含组分a)、b)和可选地c)的陶瓷原料，其中组分a)是至少一种陶瓷材料，组分b)是至少一种粘合剂(B)并且可选的组分c)是至少一种添加剂(A)。陶瓷原料优选以长丝的形式提供以用于三维(3D)打印技术，特别是FFF打印工艺中。因此，本发明的陶瓷原料可以成功地用于支撑结构和/或分离层的3D打印。此外，本发明还涉及这样的三维物体，特别是三维生坯体、三维棕坯体或三维烧结体，以及其制备方法。
