MEMS Head Technology

Written October 16, 2019

Micro-Electromechanical Systems (MEMS) is the technology of the very small, and merges at the nanoscale into “Nano-Electro Mechanical Systems” (NEMS) and nanotechnology. MEMS generally range in size from a micrometer (a millionth of a meter) to a millimeter (thousandth of a meter).

The scale of MEMS is such that it permits larger and denser arrays of smaller ink orifices, increasing resolution and printing speed. At these size scales, the standard constructs of classical physics do not always hold true. Some of the other benefits of silicon MEMS fabrication techniques feature sub-micron accuracy, robust material set and the ability for high-volume manufacturing. MEMS, as a process, really shines in creating nozzles, holes, manifolds and channel structures for the inkjet head design. MEMS based label printers are currently on the market, but if there are nozzle issues, the entire print bar must be replaced. These printers are licensed and all use the phrase "MEMJET".
