摘要： A three-dimensional printer includes a laser line scanner and hardware to rotate the scanner relative to an object on a build platform. In this configuration, three- dimensional surface data can be obtained from the object, e.g., for use as an input to subsequent processing steps such as the generation of tool instructions to fabricate a three-dimensional copy of the object, or various surfaces thereof.

摘要： An h-bridge uses a diode or other level shifter between the gates of two transistors in series. The level shifter enforces a sufficient voltage separation between the gates to ensure that both transistors cannot be turned on at the same time. In addition to mitigating cross-conduction during switching, the disclosed circuit makes it possible to control the four gates of an h-bridge with two control signals.

摘要： A build chamber of a three-dimensional printer uses directed heat to preheat a region within the chamber where a build will be initiated, and then uses circulating, heated air to maintain a target temperature for the entire build volume after the build is initiated. A fixed heating element and blower may advantageously be used for both heating steps, and preheating may be accomplished more quickly by initially directing heat at the locus of build initiation rather than diffusing heat throughout an entire build volume.
摘要翻译：三维打印机的构建室使用定向热来预热室内将要启动构造的区域，然后在构建开始之后使用循环的加热空气来维持整个构建体积的目标温度。固定的加热元件和鼓风机可以有利地用于两个加热步骤，并且可以通过初始地引导构建起始点的热量而不是在整个构建体积中扩散热来更快地实现预热。

摘要： An extruder or other similar tool head of a three-dimensional printer is slidably mounted along a feedpath of build material so that the extruder can move into and out of contact with a build surface according to whether build material is being extruded. The extruder may be spring-biased against the forward feedpath so that the extruder remains above the build surface in the absence of applied forces, and then moves downward into a position for extrusion when build material is fed into the extruder. In another aspect, modular tool heads are disclosed that can be automatically coupled to and removed from the three-dimensional printer by a suitable robotics system. A tool crib may be provided to store multiple tool heads while not in use.

摘要： An extruder for a three-dimension printer uses a printed circuit board (PCB) heating element with leads having temperature-sensitive resistance. The resulting circuit can be driven at high power to heat an extruder, or at a low power with a known current to measure a resistance from which temperature can be inferred. Thus a single circuit on a printed circuit board can be driven alternately in two modes to heat and sense temperature of an extruder.

摘要： An extrusion head of an extruder is configured to move along a feedpath independently from a heating element so that the extrusion head can yield to extrusion-related forces. Specifically, the extruder may include an extrusion head movably coupled to a thermal core to permit axial displacement of the extrusion head relative to the thermal core. In use, the extrusion head may be displaced within the thermal core when the extruder is subject to extrusion-related forces (e.g., an upward force created by a retraction of build material or a downward force created by an advance of build material). This motion can facilitate better transitions by the extruder between different layers or z-axis positions in a model during fabrication.
摘要翻译：挤出机的挤出头构造成沿着进给路径独立于加热元件移动，使得挤出头可以屈服于挤压相关的力。具体地，挤出机可以包括可移动地联接到热芯的挤出头，以允许挤出头相对于热芯的轴向位移。在使用中，当挤出机经受与挤压相关的力（例如，通过构建材料的缩回产生的向上的力或由建筑材料的前进产生的向下的力）时，挤出头可以在热芯内移位。该运动可以促进在制造过程中模型中挤出机在不同层或z轴位置之间的更好的过渡。

摘要： A three-dimensional printer positions a tool such as an extruder in three-dimensional space using a passive, i.e., non-motorized, z-axis alignment technique that generates z-axis movement based upon motorized movements along another axis. In this manner, intermittent z-axis step movements such as those from layer to layer in a multi-layer fabrication process can be performed without the need for an additional, dedicated motor for z-axis movement. The passive system may employ a variety of different gearing techniques to convert x-axis or y-axis movements into a z-axis movement under various conditions. For example, the three-dimensional printing tool may move to a predetermined position along a first axis (e.g., an x-axis or y-axis) where a passive gear assembly engages a rack or the like. When in this predetermined position along the first axis, the tool can move along a second axis and create a resulting movement on a third axis (e.g., the z-axis).
摘要翻译：三维打印机使用被动的，即非机动化的z轴对准技术，在三维空间中定位诸如挤出机的工具，该技术基于沿着另一个轴线的电动运动产生z轴运动。以这种方式，可以在不需要用于z轴运动的附加的专用电动机的情况下执行在多层制造工艺中的间歇性z轴步进运动，例如从层到层的运动。被动系统可以采用各种不同的传动技术将x轴或y轴运动转换成各种条件下的z轴运动。例如，三维打印工具可以沿着第一轴（例如，x轴或y轴）移动到预定位置，其中被动齿轮组件接合齿条等。当沿着第一轴线处于该预定位置时，工具可以沿着第二轴线移动并在第三轴线（例如，z轴）上产生所得到的运动。
