A binder ink mixture for 3D printing of ceramic parts in a binder jet process, comprising a molecular space filler and a free radical initiator.
A method for making a binder ink mixture for forming ceramic parts in binder jet printing, comprising forming a blend of a molecular space filler and a free radical initiator.
A method of manufacturing a three-dimensional (3D) ceramic part using a binder ink mixture comprising a molecular space filler, comprising:
- obtaining a binder ink mixture comprising a molecular space filler;
- printing a green part, comprising:
- printing a layer of the green part by:
- forming a layer of ceramic beads in a binder jet printer;
- printing a pattern of the binder ink mixture on the layer of ceramic beads;
- and
- curing the binder ink mixture to bind the ceramic beads in the pattern in place;
- and
- repeating the printing of layers of the green part until the green part is completed;
- and
- sintering the green part to remove organic components of the binder ink mixture and fuse the ceramic beads to form the 3D ceramic part.
