The CMOS camera works by using a sending a beam of modulated light to the target scene, and measuring the change in phase of the reflected light. Since time of flight is directly linked to the phase, it is possible to determine the range to the scene. By using an array of photo-detectors, it is possible to map the distance to several points in the scene quickly, and no scanning is required.}, | The CMOS camera works by using a sending a beam of modulated light to the target scene, and measuring the change in phase of the reflected light.

Difficulties arise in performing laser ultrasound detection on optically rough samples; this paper presents work to date on capturing SRAS images of AM constructs. Images are taken of samples made using different 3D metal printing technologies including selective laser melting (SLM) and wire and arc additive manufacturing (WAAM). Whilst this is currently conducted offline, potentially, the presented inspection system could be performed in an online capacity as the components are printed, to verify mechanical properties and provide information to feed back into the build process.}, | Difficulties arise in performing laser ultrasound detection on optically rough samples; this paper presents work to date on capturing SRAS images of AM constructs.

SRAS (spatially resolved acoustic spectroscopy) is a method of characterising material though laser generated surface acoustic waves. The grain structures of AM metal parts can be imaged using this system, which would include information on the size and orientation of the grain; this can ultimately be used to ascertain the material stiffness. In addition, this technique can be used to detect the print porosity (e.g. gaps or errors). Difficulties arise in performing laser ultrasound detection on optically rough samples; this paper presents work to date on capturing SRAS images of the AM material from the speckle reflection. Images are taken of samples made using 3D metal printing technologies including selective laser melting (SLM) and wire and arc additive manufacturing (WAAM). Whilst this is currently conducted offline, the presented system illustrates a concept that could, in the future, be able to make measurements in an online capacity.}, | SRAS (spatially resolved acoustic spectroscopy) is a method of characterising material though laser generated surface acoustic waves.

In this paper, we present our solution of measuring the surface acoustic wave generated on an as-deposited AM part. The SAW is measured using the speckle reflection off the optically rough surface, captured using a speckle knife edge detector (SKED)(figure 1). The mapped SAW velocities measured off the AM part in a 2D scan will be presented – the link between print parameters and print quality will be illustrated. Mapping the characteristics of an as-deposited part in a timely and non invasive manner is a critical improvement to the AM technology.}, | In this paper, we present our solution of measuring the surface acoustic wave generated on an as-deposited AM part.

This presentation will provide an insight into ongoing work which makes use of two techniques; optical coherence tomography (OCT) and Spatially Resolved Acoustic Spectroscopy (SRAS) for polymer and metal ALM methods respectively. Both of these techniques are of significant interest to machine builders since they are able to evaluate both surface and subsurface integrity. Through the use of OCT it is possible to discriminate between the density of subsurface regions within the near surface 500µm of Nylon 12 SLS specimen. In addition the use of SRAS is shown to detect surface pores alongside correlating crack densities with laser scan strategies. The use of these tools also presents new opportunities for inspection and discussion will also focus on how they will be used in the industrial setting.}, | This presentation will provide an insight into ongoing work which makes use of two techniques; optical coherence tomography (OCT) and Spatially Resolved Acoustic Spectroscopy (SRAS) for polymer and metal ALM methods respectively.

Beyond identification of defects, next generation machine tools will be able to propose and execute repair strategies to some classifications of defects once observed. This will represent a step change in machine tool technology and will serve to open numerous applications for additive manufacturing. This talk will firstly address the rapidly shifting state-of-the-art in this area focusing on metal/polymer powder bed fabrication methodologies. Techniques for comparing in-process evaluation apparatus will be discussed with respect to assessing the spatial and temporal capability of a given instrument. Instruments being developed at the University of Nottingham for in process metrology and monitoring will be presented. Typical data sets created by these will be introduced and capability examined. The method of machine integration and reasonable expectations as a result of future developments will be discussed. In addition recent advances at Nottingham will be introduced which highlight a new methodology for detecting and repairing cracks and pores produced in metal powder bed systems. Activities supported through European and EPSRC initiative will also be explored. These include in-process fringe projection/ photogrammetry techniques, a two-sensor approach to process optimization, a multi-sensor fusion approach for metal powder-bed fusion, laser ultrasonics and optical coherence tomography.}, | Beyond identification of defects, next generation machine tools will be able to propose and execute repair strategies to some classifications of defects once observed.

This study investigates the use of spatially resolved acoustic spectroscopy (SRAS) scan data to inform repair strategies within a commercial selective laser melting machine. Using the common aerospace nickel superalloys, Inconel 718 and CM247-LC, localised re-melting was shown to consistently reduce the depth of defect. A 50 \% reduction in defect depth was observed for both materials using different rework strategies. No appreciable variation was seen with the single-shot strategy, due inaccurate realignment.}, | This study investigates the use of spatially resolved acoustic spectroscopy (SRAS) scan data to inform repair strategies within a commercial selective laser melting machine.

Spatially Resolved Acoustic Spectroscopy (SRAS) is an acoustic microscopy technique, which utilises laser ultrasonics for the excitation and detection of surface acoustic waves for materials characterisation. This technique meets many of the requirements of a suitable inspection technique for SLM, such as non-destructive, and early studies have confirmed the ability to detect defects and measure microstructure in SLM parts using SRAS. However, significant challenges remain as the technique and instrumentation is developed towards online measurements. This talk will discuss the merits of using SRAS for in-process inspection for defect detection and characterisation, with a review to enabling remedial action. Discussion will touch on system capability, including a time-cost model and progress towards build system integration. Particular focus will be paid to the detection and characterisation of porosity, both subsurface and surface breaking.}, | Spatially Resolved Acoustic Spectroscopy (SRAS) is an acoustic microscopy technique, which utilises laser ultrasonics for the excitation and detection of surface acoustic waves for materials characterisation.

The proposed laser ultrasound technique can be used to detected both surface and subsurface defects, and can be used to inspect the material microstructure or texture. Working on as-deposited SLM material is challenging due to the high surface roughness. We will present results of the laser ultrasonic technique – spatially resolved acoustic spectroscopy (SRAS) – on as deposited material from a build chamber compatible instrument. We will discuss the possibilities for defect and microstructure control, and the challenges remaining for online inspection.}, | The proposed laser ultrasound technique can be used to detected both surface and subsurface defects, and can be used to inspect the material microstructure or texture.
