Additive manufacturing (AM) technologies, generally called 3D printing, are widely used because their use provides a high added value in manufacturing complex-shaped components and objects. Defects may occur within the components at different time of manufacturing, and in this regard, non-destructive techniques (NDT) represent a key tool for the quality control of AM components in many industrial fields, such as aerospace, oil and gas, and power industries. In this work, the capability of active thermography and eddy current techniques to detect real imposed defects that are representative of the laser powder bed fusion process has been investigated. A 3D complex shape of defects was revealed by a μCT investigation used as reference results for the other NDT methods. The study was focused on two different types of defects: porosities generated in keyhole mode as well as in lack of fusion mode. Different thermographic and eddy current measurements were carried out on AM samples, providing the capability to detect volumetric irregularly shaped defects using non-destructive methods.
Charakterisierung einer durch Überlast geschädigten GFK-Platte mit Thermografie und Ultraschall
(2013)
Eine GFK-Platte mit eingefräster Nut wurde in einem Zugversuch mit
ca. 90 kN belastet, was zu einer sichtbaren Veränderung an den Seitenflächen führte.
Anschließend wurde die Platte mit Ultraschall und Thermografie auf innere Schädigungen untersucht. Beide Verfahren konnten räumlich ausgedehnte Bereiche mit zahlreichen Anzeigen nachweisen, jedoch keine geschlossene Fläche. Mit UT wurden außerdem porenreiche oberflächennahe Schichten in dem Material detektiert. Diese Poren verringerten die Nachweisempfindlichkeit beider Messverfahren.

Active Thermography a nondestructive testing method for damage assessment in concrete structures
(2013)
As shown recently, the quantification of damage in historic masonry structures is possible by using active thermography. In this paper, a case study is presented concerning systematic studies of the determination of damage size and prognosis of damage increase inside a sandstone column by using different approaches of active thermography. Various heating sources as well as impulse and periodic heating have been compared. Reproducible investigations in regular time intervals for structural monitoring are possible.
Active thermography is sensitive to inhomogeneities at and below the surface of objects investigated. Thus, it should be useful for detecting plaster delaminations on concrete. In this paper, the results of field and laboratory investigations into plaster-covered concrete were compared. For evaluating the bonding state of the plaster it is not sufficient to study only the thermal contrasts at the surface of the investigated objects. The experimental results suggest that the overall thermal behaviour has to be considered.
