A 3D model printed ball valve is a functional, compact valve created using additive manufacturing techniques, typically with durable plastic or resin materials. Designed to control fluid flow, the ball valve features a spherical closure unit with a hollow center that aligns with the pipe when open and rotates to block flow when closed. This printed component is often used in educational prototypes, low-pressure systems, and engineering demonstrations due to its customizable design, cost efficiency, and quick production time. With advancements in 3D printing technology, these valves can now mimic the performance of traditional metal valves in select applications.
