Venturi Air Amplifier

thingiverse

This is a straightforward "Air Amplifier" that amplifies air volume through an annular Venturi arrangement, driven by high pressure air input at the small tube inlet. The design can be printed with ease using a 0.2mm nozzle and comes pre-equipped with precise support structures that must be snapped off after printing to reveal the finished device. Printing with a larger nozzle will require careful scaling adjustments to ensure proper formation of the inner gap and tube, which will otherwise be supported by an integral plug. Even a simple dust-off canister can power this device, making it a viable alternative to fans for layer cooling in 3D printing applications. As designed, the Air Amplifier may present three non-manifold edges upon completion, but most slicer software is able to automatically correct these issues.
