摘要:
In a method for producing a material layer with a recess, a first suspension containing a binder is applied through a first opening in a first template and a second suspension containing a binder and solid particles is applied through a second opening in a second template. The first opening in the first template is completely contained within the second opening in the second template such that the second suspension completely surrounds the first suspension to produce a green body. The green body containing the first and second suspensions is sintered such that the first suspension is evaporated to provide the recess and permanent cohesion of the solid particles in the second suspension is achieved.
