Description:

Jetting has become an increasingly important technology finding many applications beyond inkjet printing in areas such as manufacturing of optical devices, soldering, and DNA arrays. While there has been a great amount of technical progress in the delivery and control of droplets, breakthroughs in modeling and understanding of some of the fundamental processes need to be made in order to bring about the next generation of jetting devices.

The IMA workshop will bring together researchers from industry, government laboratories, and academia to address modeling issues arising in jetting technology. The goal of the workshop is to give an up-to-date snapshot of the state of the art, and to discuss challenges and open problems that remain in this field.

There will be three main sections in the workshop: (1) Droplet Generation (piezoelectric, acoustic, thermal, electric, pressure driven); (2) Rheology; and (3) Droplet Impact.
