    摘要: A method for the production of nano- or microscaled ID, 2D and/or 3D depositions from an solution (6), by means of a liquid reservoir (2) for holding the ink with an outer diameter (3,D) of at least 50 nm, is proposed, wherein there is provided an electrode (7,8 or 9) in contact with said ink (6) in said capillary (2), and wherein there is a counter electrode in and/or on and/or below and/or above a substrate (15) onto which the depositions are to be produced, including the steps of: i) keeping the electrode (7, 8, 9) and the counter electrode (15, 18) on an essentially equal potential; ii) establishing a potential difference between the electrode (7, 8, 9) and the counter electrode (15, 18) leading to the growth of an ink meniscus (1) at the nozzle (3) and to the ejection of droplets (13) at this meniscus with a homogeneous size smaller than the meniscus size (11) at a homogenous ejection frequency; keeping the voltage applied while the continuously dried droplets leave behind the dispersed material which leads a structure to emerge with essentially the same diameter as a single droplet, wherein the distance between the substrate (1) and the nozzle (3) is smaller than or equal to 20 times the meniscus diameter at least at the moment of nano-droplet ejection (12); wherein the conductivity of the ink (6) is high enough to stabilize the liquid meniscus during droplet ejection;

    摘要: For forming a fine structure of a desired material, nanoparticles of the same material are prepared in a suspension. A layer of the suspension is applied by a drop-on-demand printing system to a substrate. At least part of the layer is exposed to laser light for melting the nanoparticles at least partially. Upon solidification, the molten particles are sintered together to form the desired structure. Due to the low melting point of nanoparticles as compared to the melting point of bulk material, this procedure avoids damage to the substrate and provides a better control over the structure generation process. It can be used for generating metallic and non-metallic structures on various substrates. The laser light may have non-Gaussian intensity distribution or can combine multiple beams of Gaussian and non-Gaussian distribution for improving the quality of the generated structure, or it may be pulsed for improved control of the heat flow into the substrate.
