摘要： 3-D printers include an intermediate transfer surface that transfers a layer of material to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers of the material on the platen. A sensor detects the thickness of the layer on the platen after a fusing station fuses the layer. A feedback loop is electrically connected to the sensor and a development station (that includes a photoreceptor, a charging station providing a static charge to the photoreceptor, a laser device exposing the photoreceptor, and a development device supplying the material to the photoreceptor). The development station adjusts the development bias of the development device, based on a layer thickness measurement from the sensor through the feedback loop, to control the thickness of subsequent ones of the layers transferred from the intermediate transfer surface to the freestanding stack on the platen.

摘要： Provided is a three-dimensional modeling apparatus including a stage, a constraining body, a supply nozzle, an irradiation unit, and a movement mechanism. The constraining body includes a surface including a linear region along a first direction, and is opposed to the stage so that the linear region is the closest to the stage. The supply nozzle supplies a material curable by energy of an energy ray into a slit region between the stage and the linear region. The irradiation unit irradiates the supplied material with the energy ray through the constraining body. The movement mechanism moves the stage relative to the constraining body along a second direction for forming a cured layer of the material for one layer, and moves the constraining body and the stage relative to each other along a stacking direction for stacking the cured layers.

摘要： The invention relates to a device for applying flowable material to a substratum (3), which can be rotated about an axis of rotation (4), in accordance with specified image data, which are stored as pixels or as vectors of a certain Cartesian coordinate grid in a first memory (18), has at least one printing head (13A, 13B), which has a plurality of nozzles arranged at a nozzle distance from each other for discharging material drops of the flowable material and is arranged at a vertical distance from the substratum, and a controller (8) for positioning the substratum (3) in relation to the at least one printing head (13A, 13B) and the discharge of the material drops. In a second memory (19), particular polar coordinate grid points (20A, 20B) of a certain polar coordinate grid are stored, which polar coordinate grid points are arranged on circular lines (R1, R2) having a predetermined circular-line distance from each other and are arranged on first rays (A1), which have a first angular distance from each other and are arranged in the direction of origin on further rays (A2) having an angular distance from each other that is greater than the first angular distance. A computer (15) is present, by means of which the particular polar coordinate grid points (20A, 20B) stored in the second memory (19) can be transformed into coordinates of the certain Cartesian coordinate system and the Cartesian grid points thus obtained are compared with the pixels of the image file.

摘要： This invention relates to processes and systems of rapid prototyping and production. Its features includes flexible material deposition along tangential directions of surfaces of a part to be made, thereby eliminating stair-shape surface due to uniform horizontal layer deposition, increasing width of material deposition to increase build up rate, applying the principles of traditional forming/joining processes, such as casting, fusion welding, plastic extrusion and injection molding in the fabrication process so that various industrial materials can be processed, applying comparatively low cost heating sources, such as induction heating and arc-heating. Additional features include varying width and size of material deposition in accordance with geometry to be formed and applying a differential molding means for improved shape formation and surface finishing.
