摘要： A friction reduction system for reducing friction of an intermediate transfer member (ITM) of a printing system, while the ITM is guided along the printing system by a guiding arrangement. The friction reduction system includes a fluid reservoir mounted within the printing system, a fluid depositing arrangement disposed along the ITM, and a control mechanism, adapted to control depositing of fluid, from the fluid depositing arrangement onto the guiding arrangement or onto at least a portion of the ITM. Depositing of the fluid reduces friction between the ITM and the guiding arrangement.

摘要： A method of inkjet printing a gradient dielectric element in a deposition and photo-polymerization process. The method comprises: providing a plurality of complex-dielectric-inks that are inkjet printable including a nanocomposite-ink with an organic-matrix and a nanoparticle filler dispersed within. The plurality of complex-dielectric-inks have a first complex-dielectric-ink having a first photoinitiator and a second complex-dielectric-ink with a second photoinitiator. The first and second complex-dielectric-ink have different wavelength selective photo-polymerization absorption bands such that spectrally discrete exposure results in different degrees of polymerization of the first and second complex-dielectric-ink. The method further comprises providing an optical source to polymerize the complex-dielectric-inks, depositing droplets of the plurality of complex-dielectric-ink and curing the plurality of complex-dielectric-inks, wherein deposition of the plurality of layers result in a volumetric nanoparticle concentration gradient.

摘要： A liquid jetting apparatus includes a casing, a tank formed with a liquid storage chamber which stores liquid, an inlet which allows the liquid to be poured into the liquid storage chamber, and a liquid outflow channel which allows the liquid to flow out from the liquid storage chamber, a conveying mechanism which conveys a recording medium along a conveying path extending in a front-rear direction, a carriage which moves in a left-right direction, and a head mounted on the carriage and having a nozzle which jets the liquid onto the recording medium conveyed by the conveying mechanism. The tank, the conveying path, and the carriage are arranged inside the casing, the tank is arranged outside the conveying path in the left-right direction, and at least a part of the tank is arranged inside both ends of a movement area of the carriage in the left-right direction.

摘要： The techniques described herein relate generally to reconfigurable support pads for fabric image transfers. Specifically, according to one or more embodiments of the present disclosure, reconfigurable support pads are provided for fabric image transfers (e.g., silk screening, heat transfer, direct-to-garment printing, etc.). In particular, the techniques herein provide for various adjustable configurations of portions of the fabric substrate support, which may be changed for different thicknesses of garments, and more particularly, that allow for varied thicknesses found on the same garment. For example, by configuring the support in a first “flat” configuration, a plain tee shirt may lay flat, and then configuring the support in a second “two-tiered” configuration, with one portion lower (or higher) than the other, allows for a hoodie with a thicker pocket portion at the “belly” of the garment to also lay flat. Other configurations are also available, whether manually adjusted or else dynamically controlled (e.g., using actuators) based on the type of garment selected on an associated control system.

摘要： Provided are methods of fabricating an object, effected by jetting two or more different compositions, each containing a different material or mixture of materials, which, when contacted on a receiving medium, undergo a chemical reaction therebetween to form the building material. The chemical composition of the formed building material is dictated by a ratio of the number of voxels of each composition in a voxel block. Systems for executing the methods, and printed objects obtained thereby are also provided.

摘要： An inkjet printing machine for printing individual sheets comprises at least one printing station and a transport system defining a transport track for transporting the individual sheets through the printing station, along a transport direction. The transport system comprises a plurality of gripper conveyors (150) running along the transport track for holding the individual sheets during a printing process in the printing station. Each of the gripper conveyors (150) comprises an energy storage (161) for providing energy for operating a gripper mechanism (171) of the gripper conveyor (150). The printing machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.
