Direct-Write Process for UV-Curable Epoxy Materials by Inkjet Technology

Abstract

We demonstrate drop-on-demand inkjet printing technique to be a high throughput method for the patterned deposition of UV-curable epoxy materials. Different multi-nozzle printheads have been used to produce epoxy droplets with controlled volume in the range from 15 to 180 pl, and to apply the droplets with high placement accuracy. For a large dot grid pattern, which was printed by addressing 126 individual ink channels, standard deviations of sigma(x) = 2.3 micrometer and sigma(y) = 2.6 micrometers have been achieved for the error in dot placement. The deposited epoxy dots were found to form planar convex lenses with a focal length of 142 micrometer. In addition, we have successfully printed magnetic nanoparticles in a carrier fluid with the drop-on-demand printheads, as a step towards the production of composites.
