摘要： The systems and methods described herein include an approach to performing quality assessment for 3-D printed objects during the printing process, for collecting data regarding 3-D printed objects, and for capturing data to make a digital model of an object. This approach uses sensor data (e.g., digital imagery) to characterize printing progress or to detect 3-D printing defects that would otherwise result in printing incomplete objects, such as premature printing job termination, dry printing, over/under application, movement of the filament, and other defects. Sensor data capturing can also be used as part of a destructive scanning process to perform post-printing object assessment or to collect data on a real-world object to facilitate creation of a digital model. These systems and methods may leverage the discrete nature of a pixel provided through digital imagery to be assessed with limited computational resources in a non-recursive manner.

摘要翻译： 本文描述的系统和方法包括在打印过程中对3-D打印对象进行质量评估的方法，用于收集关于3-D打印对象的数据，以及用于捕获数据以形成对象的数字模型。 这种方法使用传感器数据（例如，数字图像）来表征打印进度或检测否则会导致打印不完整对象的三维打印缺陷，例如过早打印作业终止，干打印，过/下应用，移动 灯丝等缺陷。 传感器数据捕获也可用作破坏性扫描过程的一部分，以执行后打印对象评估或收集真实世界对象上的数据，以便于创建数字模型。 这些系统和方法可以利用通过数字图像提供的像素的离散特性以非递归方式用有限的计算资源进行评估。
