High-efficiency Venturi eductor redesigned for metal additive manufacturing in 316L stainless steel, combining CFD optimization with lightweight single-piece construction.

​

Project Description

KS Projects redesigned a conventional Venturi eductor specifically for metal additive manufacturing using 316L stainless steel.

The objective was to improve suction performance, reduce component weight, and eliminate the manufacturing complexity associated with conventional multi-part assemblies.

The Venturi throat, diffuser, and suction port were parametrically redesigned according to additive manufacturing requirements.

A 20-iteration CFD optimization process using ANSYS Fluent was performed to refine the internal flow geometry, reduce pressure losses, and improve suction performance.

The optimized geometry achieved less than 1.2 kPa pressure differential at 1 m/s primary flow.

An additive-manufacturing-specific lattice structure was incorporated into the shell, reducing component weight from 540 g to 422 g — a 22% reduction — while maintaining the required structural performance.

The final component was prepared for production on an EOS M 290 DMLS system, with build orientation optimized to reduce support material and post-processing.
