Project B03

In-situ characterization of additively manufactured hybrid and porous components

The primary objective of B03, within the context of the initial funding phase, is the in-situ measurement of quality-determining parameters, such as shape, temperature, reflectance behavior, and porosity, of HyPo material layers produced via L-DED, aiming to control the manufacturing process. For this purpose, an optical multisensory measurement system, consisting of an endoscopic laser triangulation sensor, an image processing sensor, and a thermographic camera, along with customized calibration and evaluation methods, is being developed and investigated.
Concurrently with the shape assessment of the deposited material layers immediately after production, their surface temperature is also recorded by a high-resolution infrared camera. By calibrating the infrared camera relative to the other sensors of the multisensory measurement system, the temperature data captured can be fused with the 3D measurement data of the component shape. Methods for detecting and characterizing material transitions in multifunctional high-performance components made of hybrid materials are being researched based on the estimation and analysis of the bidirectional reflectance distribution function (BRDF) of the component surface.
