Fine ceramic lattices prepared by extrusion freeforming.
Microextrusion freeforming of ceramic lattices from high solids ceramic pastes provides multi scale hierarchical void structures with the advantages of low shrinkage stress and high sintered density.
Fine ceramic lattices prepared by extrusion freeforming article in journal of biomedical materials research part b applied biomaterials 79 1 116 21 october 2006 with 155 reads.
Fine ceramic lattices with spatial resolution 100 m and having precise dimensions and intricate hierarchical structure are fabricated by extrusion freeforming a rapid prototyping technique which allows overall shape and structure to be controlled by computer.
The procedure can be used for any fine ceramic powder and can therefore find applications as diverse as microwave and terahertz.
