Optimization Fiber Density Design of Fibrous Ink Retaining Member in the Ink jet Cartridge
In this paper we introduce a new type of pressure regulator in the ink jet cartridge. A bundle of fiber is bundled within a polyethylene film, and inserted into the ink tank of the cartridge. The matrix of the fiber in the fiber bundle is long and straight pipe like structure. The fiber is a good pressure regulator as it provides capillary force to suck the ink and to hold the ink under certain pressure environment The compactness of the fiber determines the capillary force and the amount of ink that the cartridge can hold it is important to the cartridge designer.
It is found that, the fiber density influences the amount of the residue ink left in the cartridge after depletion, the ink usage efficiency of the ink jet cartridge, and the yield of the ink cartridge. It is suggested to design the fiber density to within the critical fiber density limitation.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
