    Powderblasting has the opportunity to become a standard technology in micromachining. To machine small details with powderbalsting, it is necessary to use a suiabled mask. In this paper four mask types ares examined. BF400 resist foil is most suitable for standard use in powderblasting for reason of simplicity. A simples metal plate can be used with less accurate dimensions (> 1mm) but having the advantage of being reusable. Electroplated copper has the opportunity to be a suitable mask for machining lateral dimentions of 50 um and less. These mask materials show that there are manu ways of using powderblasting as a microtechnology.
