AJMM is capable of machining anisotropic patterns.

Abrasive jet micromachining (AJM) is a non-traditional machining process that uses an abrasive-laden air jet to erode substrates. It's also known as abrasive micro-blasting, pencil blasting, and micro-abrasive blasting. In AJM, a focused stream of abrasive particles is carried by high-pressure air or gas and impinges on the work surface through a nozzle. The work material is then removed by erosion by the high-velocity abrasive particles. The abrasive particles impact at high velocity (200–400 m/s).

In AJM, a focused stream of abrasive particles is carried by high-pressure air or gas and impinges on the work surface through a nozzle. The work material is then removed by erosion by the high-velocity abrasive particles. The abrasive particles impact at high velocity (200–400 m/s).
AJM is a relatively new approach to the fabrication of micro structures. It's a promising technique for three-dimensional machining of glass and silicon to create economically viable micro-electro-mechanical systems (MEMS).
