3D printed filter center tube

This invention describes a filter that uses a central tube made by 3D printing. The tube is constructed from multiple layers of solidified material, with each layer having undulating strips printed in different, non-parallel directions. This intricate layering creates tiny pores throughout the tube, allowing it to filter liquids or gases. The claims specify this filter tube has a ring shape within a housing, directing fluid from an outer chamber through the tube and into a central void.

Why it matters: Since 2021, advancements in precision 3D printing and material science have made it more feasible to create complex, controlled pore structures for filtration. This could simplify manufacturing the intricate layered design.
