    AESUB - the new scanning spray for reflective and transparent surfaces evaporates on its own

    The scanning of reflective and transparent components is a challenge even for modern sensors. To be able to measure the components, they are matted using special sprays. The problem used to be cleaning the components after scanning. Conventional sprays stick stubbornly to the surfaces and are difficult to remove. Removal is time-consuming and the components are frequently rendered unusable in the process. Even sophisticated measuring equipment can be damaged by permanent adhesive sprays.


    Directly matt components in the measurement area
    Components can be directly sprayed in the measurement area using the self-evaporating AESUB scanning sprays. Within seconds, high contrast values that the scanner can easily record arise on the surface as a result of a thin, white layer. The layer thickness ranges between 1µ and 15µm.  The matting layer is dry to the touch so that the components can be handled and repositioned during the scanning process. Reference points can be directly placed on the layer. They hold significantly better than conventional sprays.
     
    No subsequent cleaning of the sprayed surfaces
    There is no need to clean components with the new scanning sprays from AESUB. The spray mist does not even contaminate the surrounding area, because the matting layer sublimates, i.e. it evaporates on its own. Depending on the spray version, the sublimation time is between 4 and 24 hours. Measuring capacities can be significantly increased because the AESUB sprays reduce the previously required preparation and post-treatment of glossy and transparent components to a minimum.
    All AESUB scanning sprays are free from titanium dioxide, which is hazardous to health.
    The self-evaporating AESUB scanning sprays contain no pigments.

    About AESUB:
    Scanningspray Vertriebs GmbH, established in 2018 in Dortmund (Germany), has specialised in the development and production of scanning sprays.  With in-depth expertise in 3D scanning and aerosol development, AESUB products are continually developed to enable faster, more efficient and more precise 3D scanning processes.

  • Automated matting of shiny and transparent parts
    Automation is progressing at breath-taking speed. Costs have to be lowered and capacities increased. In automobile manufacture in particular, this trend is clearly visible. And in optical measurement technology, too, processes are increasingly being automated. In spatially defined scanning boxes, 3D scanners mounted on robot arms rapidly and accurately digitalise the components in an extremely short space of time. However, automated measurement meets its limits when it is difficult or impossible to measure the dimensions of the components owing to their shape, size or material characteristics. These include transparent, reflective and uneven surfaces which hinder the entire optical measuring process and – if it is possible at all – often lead to distorted measurement results.

    Problematic: scanning of transparent and reflective surfaces
    With transparent surfaces, the light of the scanner shines through the surface which means that the surface structure cannot be captured.
    Similarly, with reflective surfaces, the scanner is also not able to scan the surfaces. Here, the ray of light is reflected not in a diffuse, but focused manner.

    A further problem comes from components with pronounced uneven areas. The walls of recesses cause reflections and lead to incorrect representations.

    Matting of the surfaces
    Transparent and reflective surfaces can be matted using scanning sprays. Using a newly developed spray, the AESUB scanning spray, a matt, white and homogeneous coating is generated in just a few seconds. As a result, the component’s surface become impervious to light and no longer reflects, which means that the objects can be scanned. Because the AESUB spray automatically sublimates, cleaning of the components after the scanning process – something which is time-consuming and/or costly – is no longer necessary.

    Automated spraying
    Using spray robots, the measurement of problematic surfaces is automated further: the matting is directly integrated into the automated digitalisation process. To do this, the component is arranged in the measuring cell and/or scanning box for the measuring process. Via a spraying mechanism, the

    AESUB green scanning spray is fed into the robot arm.  The robot arm travels along the path programmed for the digitalisation and, in the process, evenly sprays the component to be measured with the AESUB scanning spray. Depending on the component size, the entire spraying process lasts approx.  20 - 60 seconds. A white, homogeneous layer approx. 10 µm thick is generated, onto which reference points can also be applied without a problem. Subsequently, the digitalisation begins with a second robot arm on which the scanner is mounted and which travels along the same contours as the spray robot previously.

    Automatically sublimating spray, no contamination of the measuring environment, no cleaning

    The AESUB spray is free from pigments – such as harmful titanium dioxide – which are frequently used in conventional scanning sprays. Pigment-containing sprays inevitably cause contamination of the measuring environment. They put the user at risk and damage the component and also the sensitive measuring equipment. Because the AESUB spray evaporates automatically, no cleaning of the component or measuring environment is required. Unlike the pigment-containing sprays, the coating applied with AESUB sprays is touch-dry, which hugely simplifies the handling of the sprayed component.

  • Measurement targets or so-called reference points are often placed on the component surface to be scanned before the 3D scan. The points are used to combine the individual scan images into an overall scan of the complete component and are thus often essential for accurate scan data.

    The scanning of large component parts such as engine hoods is now becoming even quicker thanks to a net of measurement targets. The Target-Net by AESUB is laid over the object to be scanned and, just like that, reference points are provided across its whole area. The 3D scan process can start immediately. The target net is thus an efficient alternative to the adhesive dots used in the past, which had to be glued on individually and then laboriously removed again after the measurement.

    The measurement targets are distributed uniformly at intervals of approx. 100 millimetres across the entire Target-Net. The Target-Net itself measures 1500 x 2500 millimetres and has in total  approx. 300 measurement targets. Thanks to the high measurement target density, several scans can be performed very quickly from different perspectives.

    For metallic parts, a net with magnetic measurement targets is available; measurement targets hold securely to the surface. With non-metallic parts, e.g. made from stone or plastic, the Target-Net is stretched across them or, depending on the material or surface, fixed with optionally available suction pads. The reference points “float” approx. 10mm above the surface. The individual mesh threads are either not even detected by the scanner or can be cut out with a few clicks in post-processing using suitable software. The Target-Net is handy, can be packed away quickly and is easy to transport. Since the net can be reused almost indefinitely, this significantly reduces the amount of consumables required.

    Special sizes, e.g. 8000x12000 millimetres, can be manufactured on request.

    Currently, the Target-Net is equipped with 6mm retroreflective reference points. In the future there will also be a version with 3mm points. On request, Target-Nets with non-reflective points can also be produced.
