Abstract
The present invention relates to a method of forming a 3D ceramic structure by adding a 3D structure with one or more layer(s) of ceramic mixture onto a ceramic substrate. The present invention also relates to a 3D ceramic structure as well as to a green 3D ceramic structure.
Claims20
A method of forming a 3D ceramic structure comprising the steps of:
- a. providing a green ceramic substrate;
- b. adding a 3D structure with one or more layer(s) of ceramic mixture onto the ceramic substrate of step a);
- and
- c. drying and/or firing the product of step b);
- wherein the ceramic mixture comprises a ceramic material and one or more solvent(s);
- and wherein the drying shrinkage of the ceramic mixture is no more than 5% higher and no more than 5% lower than the drying shrinkage of the ceramic substrate.
The method of any one of the preceding claims, wherein adding a 3D structure with one or more layer(s) of ceramic mixture onto the ceramic substrate is carried out by microextrusion, binder jetting, or another 3D printing method.
A green 3D ceramic structure comprising one or more layer(s) of ceramic mixture on a ceramic substrate, wherein the ceramic mixture comprises a ceramic material and one or more solvent(s);
- and wherein the drying shrinkage of the ceramic mixture is no more than 5% higher and no more than 5% lower than the drying shrinkage of the ceramic substrate.
The method of claim 19, wherein adding a 3D structure with one or more layer(s) of ceramic mixture onto the ceramic substrate is carried out by a 3D printing method, preferably microextrusion. or binder jetting, or another 3D printing method.
