Powder-blast micromachining

There are no commercial powder blasting systems available because there is not such a market. Only a few places worldwide have utilized this technique. There are companies that can make custom-designed powder blasting systems. They only make to order. However, there are some companies, such as Micronit in the Netherlands, which provide powder blast micromachining services.

Powder blasting is a micromachining technique which uses a high-velocity air jet containing microparticles to impinge on and erode material from a surface.
