How to Apply
Consider 3D printing for prototyping and small-batch production of ceramic filters, heat exchangers, or other components requiring complex internal structures and specific porosity.
Limitations
The study focuses on specific ceramic powders and a particular 3D printing technology; results may vary with different materials and printers. Long-term durability and performance of the filters were not extensively detailed.
