摘要： In one of the preferred embodiments, an inkjet printhead includes a nozzle member formed of a polymer material that has been laser-ablated to form inkjet orifices, ink channels, and vaporization chambers in the unitary nozzle member. The nozzle member is then mounted to a substrate containing heating elements associated with each orifice. In a preferred method, the orifices, ink channels, and vaporization chambers are formed using an Excimer laser.

摘要： An ink transfer printing device having improved ink dot size control. The ink transfer printing device includes an ink container for retaining ink and a perforated ink transfer surface coupled to the ink container. The ink transfer surface includes at least one concentric region on the ink transfer surface about each of the perforations to control the spread of the ink. The concentric regions form flow barriers which impede the spread of the ink at each orifice. The ink dot size control provided by the present invention facilitates continuous toning, gray scale toning and multi-color printing.

摘要： A method for continuously manufacturing parts requiring precision micro-fabrication. According to the method, a surface of a mandrel having a reusable pattern thereon is moved through an electroforming bath. While the mandrel surface moves through the bath, a metal layer is deposited on the mandrel surface to define a pattern. After the metal layer has been deposited to the selected thickness, the metal layer is separated from the mandrel surface.
