摘要： An improved apparatus and method are provided to remove powder from a web, for example, in a 3D printing apparatus. A flexible blade is provided to contact and move across a first portion of the web located between adjacent portions of the web to scrape powder from the first portion without removing powder deposited on the adjacent portions. A pair of edge vacuum nozzles and a central vacuum nozzle are also provided to move with the flexible blade to remove powder from both edges of the first portion and a central region of the first portion.

摘要： A three-dimensional (3D) printer includes a receiver device, a plurality of material deposition units for depositing a material including a particulate material and a liquid vehicle onto the receiver device to form a printed layer on the receiver device, and a material removing system that includes a plurality of extraction units for gradually removing the liquid vehicle from the printed layer. A delivery system of the 3D printer may transport the printed layer from the receiver device to a build platform for stacking a plurality of printed layers and a plurality of post-deposition processing stations may be positioned along the delivery system for performing post-deposition operations on the printed layer.

摘要： A three-dimensional, additive manufacturing system is disclosed. The first and second printer modules form sequences of first patterned single-layer objects and second patterned single-layer objects on the first and second carrier substrates, respectively. The patterned single-layer objects are assembled into a three-dimensional object on the assembly plate of the assembly station. A controller controls the sequences and patterns of the patterned single-layer objects formed at the printer modules, and a sequence of assembly of the first patterned single-layer objects and the second patterned single-layer objects into the three-dimensional object on the assembly plate. The first transfer module transfers the first patterned single-layer objects from the first carrier substrate to the assembly apparatus in a first transfer zone and the second transfer module transfers the second patterned single-layer objects from the second carrier substrate to the assembly apparatus in a second transfer zone. The first and second printer modules are configured to deposit first and second materials under first and second deposition conditions, respectively. The first and second materials are different and/or the first and second deposition conditions are different.

摘要： 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.

摘要： An improved method and apparatus for adding a new layer to a stack of previously processed layers. In an example, a method is provided for mounting the previously processed layer on a build platform, mounting the new layer on a substrate, aligning the new layer with the previously processed layer, moving the new layer and the previously processed into contact with one another, and applying energy to the new layer from an energy source through the substrate to simultaneously process the new layer and bond the new layer to the previously processed layer to form a bonded processed multilayer stack on the build platform. A flexible compliant pressure conveyance media is moved into contact with the substrate to apply pressure to the new layer while the energy is being applied.
