摘要:
A durable printed composite material can include a printable layer having an image reverse printed thereon. The printable layer can be a transparent or translucent material. A metallic layer can be adhered to the image side of the printable layer using an adhesive layer. The layers are formed such that at least a portion of the metallic layer is visible through the printable layer. A method of forming a durable printed composite material can include reverse printing an image on a printable layer to form a printed surface. A metallic layer can then be adhered to the printed surface of the printable layer. Heat and pressure can be applied to the metallic layer to produce a durable printed composite material. The metallic layer can be at least partially visible through the printable layer. The durable printed composite material provides a medium which has an image having a reflective metallic background useful in a variety of applications.

A white ink jet ink includes high index of refraction particles having an index of refraction greater than 1.6 and a diameter of less than 100 nanometers and low index of refraction particles having an index of refraction of less than 1.5 and a diameter of between 100 and 1000 nanometers.
摘要:
A printed article with metallic luster and gold-like appearance that encompasses a printable media on which a printed feature has been formed with an ink composition. The ink composition contains iron oxide pigment particles that have an average particle 5 size in the range of about 3 to about 300 nm and the printable media contains a bottom supporting substrate and an ink-absorbing layer with pore diameters that are smaller than the average size of the iron oxide pigment particles. In such printed article, the ink composition forms onto the printable media a printed feature that has a thickness that is below about 300 nm.

A printed medium having a metallic luster includes an ink-receiving layer on a substrate and a layer of metal oxide particles disposed on the ink-receiving layer. A portion of the ink-receiving layer corresponding to at least one feature includes a non-particulate, light-absorbing colorant dispersed in the ink-receiving layer. An amount of the non-particulate, light-absorbing colorant in the ink-receiving layer portion is sufficient to render a predetermined hue to the metallic luster of the at least one feature. The metal oxide particles have an average diameter of about 3 nm to about 300 nm. The ink-receiving layer has pores that are smaller than the average diameter of the metal oxide particles.
摘要:
A printed article with optically variable properties that includes a printable media on which a printed feature has been formed with an ink composition. Said ink composition contains metal oxide particles that have an average particle size in the range of about 3 to about 180 nm and that have a refractive index superior or equal to 1.2. The printable media contains a bottom supporting substrate, an ink-absorbing layer and a metallized top layer with pore diameters that are smaller than the size of the metal oxide particles, and the ink composition forms, onto the printable media, a printed feature that exhibits optically variable properties.

A method of balancing a microelectromechanical system comprises determining if a microelectromechanical system is balanced in a plurality of orthogonal dimensions, and if the microelectromechanical system is not balanced, selectively depositing a first volume of jettable material on a portion of the microelectromechanical system to balance the microelectromechanical system in the plurality of orthogonal dimensions. A jettable material for balancing a microelectromechanical system comprises a vehicle, and a dispersion of nano-particles within the vehicle, in which the total mass of jettable material deposited on the microelectromechanical system is equal to the weight percentage of nano-particles dispersed within the vehicle multiplied by the mass of jettable material deposited on the microelectromechanical system. A microelectromechanical system comprises a number of unbalanced structures, and a number of droplets of jettable material disposed on the unbalanced structures, in which the droplets of jettable material balance the unbalanced structures in a plurality of orthogonal dimensions.
摘要:
Solid freeform fabrication (SFF) systems for producing a three-dimensional object and methods of producing three-dimensional objects are disclosed. The SFF system includes a dispensing system and a curing system. The dispensing system is adapted to dispense a radiation initiator and a build material. The radiation initiator and the build material are stored separately in the dispensing system and are dispensed separately. The curing system cures the radiation initiator and the build material after each has been dispensed.
