A novel production method for porous metal components has been developed byapplying powder space holder (PSH) method to metal powder injection molding (MIM) process.The PSH-MIM method has an industrial competitive advantage that is capable of net-shapemanufacturing the micro-sized porous metal products with complicated shapes and controlledporosity and pore size. In this study, the small impeller with homogeneous micro-porous structurewas manufactured by the PSH-MIM method using porous compounds composed of fine stainlesssteel 316L powder and polymethylmethacrylate (PMMA) particle. The effects of combinations insize and fraction of PMMA particle on dimensional tolerance and variation of sintered porousspecimens were investigated. It was concluded that the PSH-MIM method could manufacturecommercially micro-porous metal components with high dimensional accuracy
