    Abstract: An apparatus performing as a base for printing 3D objects using high temperature thermoplastics employing additive manufacturing methods is provided. The apparatus comprises a heated build platform, a thin removable plate secured on top of the build platform, a high temperature polymer coating applied over the removable plate, and surface treatment of high temperature polymer coating to maintain adhesion between 3D object and printing surface. Also, the removable plate has low coefficient of thermal expansion compared to build platform below it, for avoiding bowing of the plate as it is heated due to heated build platform, hence providing flat printing surface. The thin removable plate allows 3D objects to pop off the plate upon cooling, without damaging the polymer coating, the plate, or the object. It also allows for continuous operation of printing, while the plate is released for cooling, a new plate is installed for printing.

    Abstract: The present invention provides a system and a method for real time monitoring and identifying defects occurring in a three dimensional object build via an additive manufacturing process. Further, the present invention provides in-situ correction of such defects by a plurality of functional tool heads possessing freedom of motion in arbitrary planes and approach, where the functional tool heads are automatically and independently controlled based on a feedback analysis from the printing process, implementing analyzing techniques. Furthermore, the present invention provides a mechanism for analyzing defected data collected from detection devices and correcting tool path instructions and object model in-situ during construction of a 3D object. A build report is also generated that displays, in 3D space, the structural geometry and inherent properties of a final build object along with the features of corrected and uncorrected defects. Advantageously, the build report helps in improving 3D printing process for subsequent objects.

    Abstract translation: 提供了使用采用添加剂制造方法的使用高温热塑性塑料作为打印3D物体的基座的装置。 该装置包括加热构建平台，固定在构建平台顶部的薄可移除板，施加在可移除板上的高温聚合物涂层，以及表面处理高温聚合物涂层以保持3D对象和印刷表面之间的粘附。 此外，与其下的构建平台相比，可拆卸板具有低的热膨胀系数，用于避免由于加热构造平台而被加热的板的弯曲，因此提供平坦的打印表面。 薄的可移动板允许3D物体在冷却时弹出板，而不会损坏聚合物涂层，板或物体。 它还允许连续打印操作，而板被释放以进行冷却时，安装新的印版用于打印。

    Abstract: A FFF-based 3D printer includes a thermal management system that incorporates liquid cooling for the cooling block. In the illustrative embodiment, the thermal management system includes a coolant block that couples to the surface of the existing cooling block, a liquid-coolant reservoir, a fan for cooling the reservoir, a pump for pumping the coolant, and conduits for conducting the coolant to and from the coolant block. Embodiments of the invention provide a way to prevent or substantially reduce the incidence of clogging as otherwise occurs when attempting to print high-temperature, high-viscosity materials using FFF-based 3d printers.
