摘要：一种五轴联动3d打印机，涉及3D打印机领域。该装置中基材驱动单元用于驱动控制基材在基座上进行旋转运动；喷头驱动单元用于在水平和竖直方向上控制3D打印机的喷头的位置；扫描单元用于扫描拍摄基材的运动轨迹，并将运动轨迹信息传输至电控系统中；电控系统用于收集扫描单元的信息并控制喷头驱动单元、基材驱动单元的运动。该装置实现了在x、y、z轴方向上精确控制喷头的位置，且将转台放置在基座的凹槽内部，且使用梯形摆臂，使得旋转中心低于摆臂旋转中心，降低了转台的高度，从而降低了驱动装置整体的高度，并且也降低了成本。

摘要： A method for 3D printing a part with an additive manufacturing system includes printing a first portion (302)(308) of a part (342) in a layerwise manner and analyzing a topology (344) of the first portion (302)(308) of the part. The method includes determining a tool path for printing a second portion (306) of the part on a surface of the first portion (302) of the part (346), and pre-heating the first portion (302)(308) of the part along the tool path as a function of the topological analysis of the first portion of the part (348). The method includes printing the second portion (306) of the part along the tool path (350).

摘要： A system and method of producing a three-dimensional object are provided. The method includes providing a volume of radiation-reactive material; illuminating the radiation-reactive material with patterned radiation such that a portion of the volume of radiation-reactive material corresponding to the three-dimensional object reacts to form the three-dimensional object and a remaining portion remains unreacted; and removing the remaining portion of the radiation-reactive material to provide the three-dimensional object. The illuminating the radiation-reactive material with patterned radiation is based on a minimization of deviations of an energy deposition density below a first threshold in an object zone, an unconstrained buffer zone surrounding the object zone, and a minimization of deviations of energy deposition density above a second threshold in a zone surrounding the buffer zone. The object zone corresponds to a location of the three-dimensional object.

摘要： Bei einem Verfahren zur Herstellung mittels eines additiven Fertigungsverfahrens oder eines 3D-Druckprozesses wenigstens eines Bauteils aufweisend wenigstens zwei Baumaterialen mit je einer kritischen Verweilzeit T_x_max werden Daten zur Herstellung des Bauteils bereitgestellt und das Bauteil in wenigstens einen Bauabschnitt mit entsprechenden Bauabschnittinformationen zerlegt. Nach einem Äbleiten wenigstens eines Baumaterialvolumens und wenigstens einer mittleren Äustragsrate pro Bauabschnitt aus den Bauabschnittinformationen wird wenigstens eine Bauzeit pro Bauabschnitt und wenigstens eine resultierende Verweilzeit t_x je Baumaterial aus dem Baumaterialvolumen und der Äustragsrate berechnet. Die resultierenden Verweilzeiten t_x werden mit den jeweiligen kritischen Verweilzeiten T_x_max der entsprechenden Baumaterialien abgeglichen. Dadurch, dass wenigstens eine Anpassung der Daten, sodass die jeweiligen resultierenden Verweilzeiten t_x unter den jeweiligen kritischen Verweilzeiten T_x_max der entsprechenden Baumaterialien liegen vorgenommen wird, wenn wenigstens eine resultierende Verweilzeit t_x die jeweilige kritische Verweilzeit T_x_max des entsprechenden Baumaterials überschreitet ergibt sich eine Optimierung in Hinsicht auf den Verbrauch des benötigten Baumaterials und der Qualität des Bauteils.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for an additive manufacturing heat transfer simulation process. The process includes converting a model of an object into a node representation of the object and generating a network graph of the object based on the node representation. For each block of nodes in the node representation the process includes: applying a simulated heat to the block of nodes by multiple causation functions, performing an energy balance of heat flow into and out of the node to determine the energy stored in the node, and estimating a diffusion of heat to other nodes using physics based edge weights between nodes in the network graph. The process includes generating a representation of an estimated heat distribution within the object.

摘要： According to one aspect, there is provided a method of automatically creating sacrificial parts to be printed in the three-dimensional printer. The method comprises obtaining object model data relating to a three-dimensional object to be printed in a build chamber by a three-dimensional printer. The method determines whether the object will likely be deformed during a curing process of contents of the build chamber, wherein the curing process comprises heating of the contents of the build chamber and generating a gas flow. If the determination is affirmative, the method includes generating updated object model data including additional object to be printed in proximity to the object, the additional object to prevent deformation of the object due to the gas flow applied during the curing process.
