Heat Transfer Issues in Print-heads: Control and Applications
Abstract:Thermal Control in MEMs is becoming a major subject. As the manufacturing capabilities increase and help design and build more complex structures, driving more power in smaller scale dimensions it becomes a must to harness the heat flows within the device. Sometimes, to enable a concrete function that precise, accurate heat transfer, other times just to ensure device and operation reliability. We will review the subject of heat transfer in MEMs in general and print/heads specifically.
MEMs in general and thermal inkjet print-heads in particular have different functional layers and structures designed for its intended function. When considering control over the MEMs desired operation this puts a series of constraints on the dimensions and material properties of this layers that are discussed. Equally important is the degree of “intelligence” build up on the device itself has an impact on the capability for Thermal and Energy Control. Having more capability is an enabler of several features such as speed of operation but many times needs to be traded by cost. Discussion of current solutions such as sensors in the print-heads, firing pulse schemes, pulse width modulation and others are discussed in the paper.
Last but not least it is increasingly important to take a global system perspective when designing for Thermal Control in MEMs since many of the times MEMs are meant to work within a system where other components act as important heat sources.

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.
