Abstract: A self-monitoring additive manufacturing system and method of operation utilizes a surface imaging monitor to image a surface of a slice of a workpiece for storage and processing of the image to detect surface anomalies. The monitoring may operate in real time and in unison with an energy gun of the system for correction of the anomalies in real-time by re-melting of the anomaly.

Abstract: A method of operating an additive manufacturing system (20) utilizing a layer-by-layer thermo-mechanical analysis system (68) includes the steps of pre-modeling a structure or workpiece (38) into a plurality of slices (42) stacked from a bottom slice (42C) to a top slice (42A) of the plurality of slices (42), assuming a second slice (42B) modeled immediately below a first slice (42A) is a rigid substrate, and run a response force analysis for the first slice (42A). The analysis system may reiterate this process for each slice (42A-42C) calculating a force distribution map (72) for each slice (42A-42C), and adding the force distribution maps (72) to a total response force map (70) of the entire structure (38). The additive manufacturing system (20) may then use the total response force map (70) to optimize material properties for selected regions of each slice (42A-42C) to a sacrificial support structure (74S) and/or the final product.

Abstract translation: 使用逐层热机械分析系统（68）操作添加剂制造系统（20）的方法包括以下步骤：将结构或工件（38）预先建模为多个层叠（42）堆叠的切片 假设在第一切片（42A）正下方建模的第二切片（42B），假定在多个切片（42）中的顶切片（42A）的底切片（42C）是刚性基底，并且运行响应力分析 第一切片（42A）。 分析系统可以对每个切片（42A-42C）计算力分布图（72A）的每个切片（42A-42C）重复该过程，并将力分布图（72）加到总响应力图（70） 的整个结构（38）。 添加剂制造系统（20）然后可以使用总响应力图（70）来将每个切片（42A-42C）的选定区域的材料特性优化为牺牲支撑结构（74S）和/或最终产品。
