The company is committed to advancing inkjet technology and has a strong focus on research and development to maintain its competitive edge. By leveraging advanced simulation tools, FUJIFILM Dimatix aims to enhance the performance and efficiency of their printhead actuators, ensuring high-quality printing solutions for their diverse customer base.
挑战
The primary challenge faced by FUJIFILM Dimatix was to design unimorph diaphragm actuators for their newest ink deposition products. These actuators needed to be miniaturized to reduce costs while maximizing deflection and matching the actuator's impedance to the flow channels and nozzle. The goal was to generate a droplet meeting a target mass at a given velocity with a target maximum firing frequency for the available voltage. The complexity of the design required a deep understanding of the interactions between the piezoelectric materials and the surrounding components, necessitating a robust simulation approach to optimize the design parameters.
解决方案
To address the challenge, FUJIFILM Dimatix employed a two-stage modeling approach using COMSOL Multiphysics software. In the first stage, various actuator geometries were modeled to determine their functional parameters. These parameters were then used in a complete jet model to understand the system's response. The simulation included different layers for the silicon, metals, insulators, and PZT, as well as sections of the ink-filled pumping chamber and neighboring flow channels. By simulating the actuator's deflection under pressure and voltage loads, the team could extract valuable compliance and output data. This information was crucial for optimizing the design to meet the tight specifications and smaller geometries required for the new printheads.

Improving Vending Machine Profitability with the Internet of Things (IoT)
The vending industry is undergoing a sea change, taking advantage of new technologies to go beyond just delivering snacks to creating a new retail location. Intelligent vending machines can be found in many public locations as well as company facilities, selling different types of goods and services, including even computer accessories, gold bars, tickets, and office supplies. With increasing sophistication, they may also provide time- and location-based data pertaining to sales, inventory, and customer preferences. But at the end of the day, vending machine operators know greater profitability is driven by higher sales and lower operating costs.
