Method of calibrating a dispenser

A method is used to identify and compensate for errors created by changes in the relative positions of a deposition unit and a vision system of a dispenser. The method includes calibrating the vision system, dispensing a pattern of features over a working area, moving the vision system over a deposition location to locate a deposition, obtaining an image of the deposition, tagging data associated with the image, calculating a relative distance between the deposition unit and the vision system, storing correction data with spatial location in a file for later use, and using the stored data to make small corrections prior to dispensing additional material.

System and method for controlling powder bed density for 3D printing

A system and corresponding method for additive manufacturing of a three-dimensional (3D) object to improve packing density of a powder bed used in the manufacturing process. The system and corresponding method enable higher density packing of the powder. Such higher density packing leads to better mechanical interlocking of particles, leading to lower sintering temperatures and reduced deformation of the 3D object during sintering. An embodiment of the system comprises means for adjusting a volume of a powder metered onto a top surface of the powder bed to produce an adjusted metered volume and means for spreading the adjusted metered volume to produce a smooth volume for forming a smooth layer of the powder with controlled packing density across the top surface of the powder bed. The controlled packing density enables uniform shrinkage, without warping, of the 3D object during sintering to produce higher quality 3D printed objects.

Nanoparticle application with adhesives for printable electronics

A circuit assembly can be made by adhering a conductive element to a substrate with an adhesive. A first layer including an adhesive can be applied over at least a portion of a surface of the substrate. A second layer including a conductive metal can be applied over at least a portion of the first layer. The first layer and the second layer can be exposed to a temperature for a duration of time to (1) fuse the conductive metal together in at least a portion of the first layer and (2) cure the adhesive of the second layer. The fusing can be substantially complete before the curing is substantially complete to enhance bonding of the adhesive to the fused conductive metal.

Process of fabricating a beaded path on the surface of a substrate, a system for fabricating such a path, use thereof, and a kit

The invention relates to a process of fabricating a beaded path on the surface of a substrate, the process comprising: preparing a dispersion of particles in a liquid; supplying the prepared dispersion to at least one electrically conductive microcapillary in a continuous manner; forming and maintaining a convex meniscus of the dispersion at the outlet end of the microcapillary positioned above and/or below the surface of a substrate; applying alternating voltage to the microcapillary so that a beaded structure is formed between the dispersion meniscus and the surface of the substrate; and moving the microcapillary relative to the substrate and/or the substrate relative to the microcapillary so as to deposit the particles of the formed beaded structure on the surface of the substrate and simultaneously rebuild the beaded structure formed between the dispersion meniscus and the surface of a substrate. The invention also relates to a system for realizing this process and the use of the beaded path fabricated in accordance with the process of the invention for the production of electrodes in photovoltaic cells, new generation clothing, electronic components, including flexible electronics, artificial flagella, photonic and optomechanical materials, as well as for the regeneration of damaged paths on the surface of a substrate. The present invention also relates to a kit comprising a substrate and a beaded path fabricated on the surface of that substrate according to this process. The invented process is simple, efficient, hence economical, and enables fabricating beaded paths that retain their properties after turning off the voltage initially used to form a beaded structure. Moreover, the process occurs outside a liquid environment and enables fabricating of paths in a continuous manner, that is, through the formation of the beaded structure and its simultaneous depositing on the surface of a substrate allowing the fabrication of beaded paths of arbitrary length.
