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 device includes a coater, a dispenser, and a treatment portion. The coater is to coat, layer-by-layer, a build material relative to a build pad to form a 3D object. The dispenser is to at least dispense a fluid including a first at least potentially electrically conductive material in at least some selected locations of an external surface of the 3D object. The treatment portion is to treat the 3D object to substantially increase electrically conductivity on the external surface of the 3D object at the at least some selected locations.

摘要： 3-D build jobs having surrogate supports, 3-D printers using surrogate supports, and techniques to support vulnerable regions of build pieces using surrogate supports are disclosed. The surrogate supports are generated in a first material configuration and are offset via a gap from the vulnerable regions. The gap comprises a second material configuration, such as loose or partially fused powder on which the build piece can be supported during 3-D printing. In alternative embodiments, the gap instead includes thin manual ties or a solid body using material that is stronger but more amenable to breaking off without damaging the build piece. Post-processing steps are dramatically reduced as the surrogate supports and gaps facilitate virtually error-free separation from the build piece. In an embodiment, the surrogate supports include a support structure extending to a fixed base underneath, the fixed base being a build plate or a global surrogate.
