Abstract:
A method and apparatus for creating three dimensional solid forms in metals, ceramics, organics or any combination thereof is made possible using a computer controlled system to create local environmental conditions that favor deposition from a material stream, precursor gas, weld process or plasma. In order to increase control and accuracy, the material can also be placed while the target area is monitored by a broadband poly-spectral imaging system, which provides dimensional, geometrical, chemical composition, stress and temperature feedback to the computer controlling the process. The local environmental conditions in the deposition area are controlled for magnetic, electric, and acoustic fields as well as for temperature, pressure, flow dynamics, and atmospheric composition. Complex materials can be nullwrittennull to match a computer's file of a three dimensional shape with virtually any material composition, surface finish, and geometrical complexity. Discrete components, such as microspheres, optical, electronic or any other components or materials that do not lend themselves to the deposition process, can be inserted and the shape written around them to make them an integral part of the final form. While the system can nullwritenull a three-dimensional shape it can also be used to nullerasenull some or all of a shape. The environmental conditions can also be changed so that material can be removed under computer controlled so that any corrections or final features can be created including such operations as final polishing or surface finishing. The digital files containing the three-dimensional image, environmental and compositional data can be sent to remote locations where the data can be used to write a new three dimensional object.
Abstract:
A process is disclosed for making ultra micro fiber artificial leather. Firstly, a substrate is made from ultra micro fibers of sea-island type and a reinforcement layer via needle punch or water jet. The ultra micro fibers all include a sea component and island components. Then, the sea component of each of the ultra micro fibers is dissolved. Finally, the substrate is submerged in elastomeric resin.
Abstract:
The invention provides a method and apparatus for depositing a soluble material, such as an organic polymer, onto a substrate using an inkjet print head. The substrate is provided with an array of alignment marks and the material in solution is deposited when substantially aligned with one of the alignment marks to provide an alignment dot of the material in solution. The alignment dot is viewed before the deposited material in solution has dried. Cross-shaped alignment marks are used to facilitate viewing of the positions of the alignment dot.

Abstract:
The present invention is directed towards a method and means for molecularly patterning a surface to promote the patterned attachment of a target adherent. In some preferred embodiments the target adherent is a biological cell, but it can more generally be a biological or chemical species for which attachment at specific sites is desired. The method generally involves using a stamp to microcontact print a first type of molecule on the surface. With the stamp remaining in situ, the process then involves fluidic patterning of a second type of molecule through selected openings defined by selected recesses in the stamp and the surface itself. The second type of molecule should have an adhesion property relative to the target adherent that is complementary to that of the first type of molecule. The stamp is removed only after both the first and second types of molecules have been transferred to the surface.

The present invention relates to a forming method using a thermal transfer printing sheet which is capable of implementing a 3D pattern through a method of forming a protruded surface using a thermal conduction difference of each portion in such a manner that a partial deposition thermal transfer printing sheet is printed on a surface of a base material of a plastic related thing, or a gold silver thin film is partially printed by a carving roller, and then the printed surface is heated to a certain temperature, so that the surface is divided into a heat blocked portion and a heat absorbed portion. In the forming method using a partial deposition thermal transfer printing sheet or a gold silver thermal transfer printing sheet according to the present invention, a thermal transfer printing sheet is drynullprinted using only a heat and pressure, and a protruded surface is easily formed through a thermal diffusion process. It is possible to form various natural protruded surfaces. A work process is simple, and an excellent 3D pattern and economical product are implemented. In addition, it is possible to form various natural 3D patterns without any limit in the size of the base material or the type of the roller.
Abstract:
The present invention comprises a machine and method for applying chemicals with substrates in a continuous manner, as opposed to batch processes. The machine uses non-aqueous solvents as a carrier medium for the chemicals. The non-aqueous solvents are then evaporated away, leaving the chemicals on the substrates. Additionally, the non-aqueous solvents are then continuously condensed, purified and recycled through the machine.
