The Expanding Role of Semi-Conductive Polyurethane in Electro-Photographic Systems
a) Electrical Properties; Volume Resistivity, Change in Volume Resistivity over time (and/or over total energy transmitted), Change in Volume Resistivity under differing temperature and humidity conditions, Other electrical properties such as R/C charge-decay time and Refresh rate and relation to nip residence time.
b) Physical Properties: Compression Modulus and Durometer [JIS or Shore] (relation to nip width), Tensile, Tear, Shear and Cut Strength, Resilience, Compression Set, Wear and Abrasion Resistance, Surface Energy and release characteristics and COF. Chemical and ozone resistance, Surface roughness, Load and Dynamic properties (tan-δ, Hysteresis and balancing issues)
c) Base Chemistry: Material class or base polymer group (i.e. Polyester or Polyether Polyurethane and how this relates to Chemical Resistance and Hydrolytic Stability.), and the use of differing conductive agents in these systems.
d) Attribute Defect Criteria and Dimensional tolerance issues.

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.
