Recently, the number and types of measurement devices that collect data that are used to monitor laser-based powder bed fusion of metals processes and inspect additive manufacturing metal parts have increased rapidly. Each measurement device generates data in a unique coordinate system and in a unique format. Data
In a 3D digital manufacturing environment—the 3D-printing devices, power, and support equipment—are the OT, and data gathering devices and computing equipment are the IT. "There is a range of 3D technologies that are available to go from art to part," said Chandrakant Patel, chief engineer at HP and an ASME fellow.
Abstract. A paradigm shift in the traditional sequential design approaches is critically essential to create application-specific hierarchical and multifunctional materials with superior long-term performance for next-generation energy technologies involving extreme environments. In the current work, we aim to leverage the flexibility and
Abstract. Additive manufacturing (AM) provides design flexibility and allows rapid fabrications of parts with complex geometries. The presence of internal defects, however, can lead to the deficit performance of the fabricated part. X-ray computed tomography (XCT) is a nondestructive inspection technique often used for AM parts.

One of the key barriers to widespread adoption of additive manufacturing (AM) for metal parts is the build-up of residual stresses. In the laser-based powder bed fusion process, a laser selectively fuses metal powder layer by layer, generating significant temperature gradients that cause residual stress within the part.
