Abstract: A three-dimensional (3D) inkjet printer is configured to build up an object by printing a series of layers and stacking them to form the object. In order to speed printing, drying of each layer is accelerated by using a pressure differential to extract liquid vehicle from the ink, and by moving the printed layer away from the inkjet print heads before drying so that the inkjet print heads may print the next layer. The dried printed layer may also be conditioned and/or cured. Dried printed layers are stacked at a build station to assemble the finished object.

Abstract: A multi-material three-dimensional printing apparatus is provided. The provided apparatus includes two or more print stations. Each of the print stations includes a substrate, a transportation device, a dispersion device, a compaction device, a printing device, a fixing device, and a fluidized materials removal device. The apparatus also includes an assembly apparatus in communication with the two or more print stations via the transportation device. The apparatus also includes one or more transfer devices in communication with the assembly apparatus. The apparatus also includes a computing and controlling device configured to control the operations of the two or more print stations, the assembly apparatus and the one or more transfer devices.

Abstract: A tactile sensor includes a first insulating layer having a first array of electrically conductive strips embedded therein and extending in a first direction. An intermediate layer of conductive soft polymer material is positioned above the first insulating layer and the first array of said electrically conductive strips. A second insulating layer having a second array of electrically conductive strips embedded therein, which extend in a second direction which is different than the first direction, is positioned above the intermediate layer. The first array of electrically conductive strips are connected to the second array of electrically conductive strips, and both the first and second array of electrically conductive strips are also connected to an impedance measuring device.
