Summary:

For its traditional graphics applications inkjet printing delivers isolated drops of colour to produce a pixelated image. For many of the new applications that use inkjet printing as a fabrication tool, continuous features are required (e.g. to promote electrical conductivity, or to provide barriers and junctions in devices); hence the interactions between adjacent printed drops must be considered. In addition a large range of fluids need to be delivered including polymer solutions and dense nanoparticle suspensions. To successfully fabricate objects a number of conditions must be satisfied concerning fluid properties and drop placement accuracy. It has been proposed that fluids are printable within the bounds 1
