Thermal Inkjet Printing

In this paper, a thermal inkjet printing simulation model is established in the CFD simulation platform, and the influence of inkjet driver parameters and ink physical parameters on the printing process is studied by numerical simulation. The evaporation-condensation model is coupled with the VOF multiphase flow model in Fluent software to establish a thermal inkjet printing process simulation model. Based on the orthogonal test method, we investigate the influence of fluid physical parameters (ink viscosity, surface tension) and inkjet driver parameters (heater temperature value) on droplet formation by changing the physical parameters of the material and the boundary conditions of the model. Through the comparison of the results, exploring the adjustment rules of thermal inkjet technology and obtaining the optimal combination of material and process parameters for high-quality ink drop formation.

AbstractBiomaterials for development of resorbable, three-dimensional tissue scaffolds have been used in a modified thermal inkjet printing system to explore compatibility of materials, solvents and the printing system. The polymers included collagen (type I), sodium alginate, fibronectin, poly-lactic co-glycolic acid (PLGA), polyethylene glycol (PEG), and tetraglycol were tested. Single-walled carbon nanotubes were combined with the biopolymers to determine which systems in which they would blend well, and be able to print. Uncovering which biopolymers may be printed together offers insight into development of materials which most closely match the properties of biological tissue.

This article focuses on researchers at Eastman Kodak Co. who are working toward a new generation of inkjet printheads that are based on microelectromechanical (MEMS) technology. The prize is that the MEMS scale has the potential to advance the quality of inkjet images by permitting larger and denser arrays of smaller ink orifices, to increase resolution and printing speed. In addition, the company expects that economies of scale of MEMS manufacturing will make printers more affordable by decreasing production costs. Currently, inkjet printheads use one of two approaches for ejecting ink. One uses piezoelectric channels filled with ink. The printer applies a voltage across each channel, which deforms to squeeze out the ink. But limitations in the manufacturing process make it difficult to increase the size of the orifice array. The biggest challenge in using CFD to simulate the inkjet printing process is keeping track of the drops free surface. Modeling problems such as Delametter’s, where the surface tension plays an important role, require accurate resolution and tracking of fluid surfaces. They also require an evaluation of surface curvatures and sensing where and how fluid adheres to solids.
