  8. 8. Section 2What is Inkjet Printing?
  9. 9. What is Inkjet Printing? A mechanism for controlled ejection of discrete drops of fluid Examples of actuation mechanisms: Deformation of piezoelectric crystals Thermal expansion of bubbles Effectively analogous to a fountain pen, except much smaller! Drop volumes1-80 pL
  10. 10. What is Inkjet Printing? Ink channel Nozzle Ligament SatellitePressure wave Substrate Ejecting ink Drop formation Drop ejection Drop travel Drop on substrate Drop formation controlled by: Determined by a complex interplay of: Rheology Chemical functionalities Surface tension Polymer structure Viscoelasticity Particle size and shape
  11. 11. What is Inkjet Printing? Low surface Medium surface High surface tension tension tensionInk behaviouron substrate Surface tension of ink relative to surface energy of substrate controls behaviour of ink drops on substrate Printed features are built-up drop by drop Ability to fine tune morphology of printed features by adjusting ink properties UV-cured ink UV-cured ink on plastic on copper
  12. 12. What is Inkjet Printing? Liquid carrier Surfactants Binders/ Adhesion bulk matrix promoters Rheology Other modifiers additives Functional Colorants materials
  13. 13. What is Inkjet Printing?Effect ofparticles Same size as Slightly smaller Much smaller than nozzles than nozzles nozzles Nozzles typically 20-30 m in diameter Particles in inkjet inks typically sub-micron Development of inkjet inks has been reliant on the development of nanoparticulates Key area of experience is producing stable particle dispersions High density particles tend to settle and reduce reliability Settling prevention - ink formulation and/or recirculating printhead technology
  14. 14. What is inkjet Printing? Substrate? End-user? Processing? Porous Non-porous Adhesion Line speed Paper Polymer Scratch resistance Temperature Polymer Metal Solvent resistance UV sensitivity Textile Glass Tensile properties Environmental Aqueous Oil-based Ink Types Solvent-based Phase change UV-curable
