Now it’s official: paintings and pieces of art that have been scanned with the FARO Focus3D suffer no damage through heat. This has been confirmed by a report by Seibersdorf Labor GmbH.
The recordings of pieces of art or interiors of museums is quick and reliable with laser scanners – and can even be done during visiting hours thanks to the safety of scanners for eyes. Nevertheless, the question of whether pieces of art suffer damage as a result of scanning arises time and again. Reason enough for FARO to have this danger investigated in a report.
Oil paintings are seen as particularly sensitive. Paint and oil have low thermal conductivity and heat capacity values. The high-energy laser could cause an increase in the temperature on the surface and damage the substance of the painting considerably. The report does away with these fears.
For a worst case scenario, a FARO Focus3D X was set up at a distance of one metre from an oil painting – without any protective glass between the piece and the scanner. If a scan is conducted in which the scanner moves horizontally – as is customary in practice – there is a temperature increase on the surface of the oil painting of less than 1.3 degrees Celsius. Even if the head of the scanner doesn’t move and the painting is thus scanned with the laser beams for several minutes, the maximum temperature increase is under 2 degrees Celsius.
To test restorative techniques for example, it is normal to place items with oil paints in an oven for several days at over 60 degrees Celsius and so accelerate an aging process. Against this backdrop, it quickly becomes clear that a short-term temperature increase of less than 2 degrees Celsius due to the FARO Focus3D will cause no damage. This has now been confirmed in the report by Seibersdorf Labor GmbH. It also permits the conclusion that photochemical effects are very unlikely at a wavelength of 1,550 nm – good news for the use of the FARO family of laser scanners in the area of cultural assets.
The Dancing Faun was discovered on October 26, 1830 in the ruins of the most opulent Roman home discovered at Pompeii: the House of the Faun, as it later became known, which was also home to the Alexander Mosaic. The Faun is thought to be either a 2nd-century Greek original, or a very high-quality Roman copy.
With help from the FARO Edge ScanArm HD, Cosmo Wenman were able to scan a 18th-centruy plaster cast of the Faun at the Skulpturhalle Basel museum. The scan did however require some digital resculpting to restore loss of detail in the plaster and to restore two broken fingers on his left hand. With this Cosmo Wenman plan to use the 3D scanned data to cast a 1:1 copy in bronze, the first of its kind.
Ideal for capturing highly accurate and detailed historical artifacts, the FARO Edge Scan Arm can enable the reverse engineering or even aid in the restoration of artefacts just like that of the Dancing Faun. However the products versatility means that, no matter what you are up against, be it a need to perform 3D inspections, CAD-to-part analysis or alignments – FARO’s portable CMMs are the industry standard in Metrology.
Stampinox S.r.l., a leading company in the hot-forged special fasteners sector, is located in Merone, Italy, halfway between Como and Lecco. It manufactures fasteners with no dimension limits and with diameters as small as M6 (metric system) or ¼” (imperial system), in alloy and stainless steels, titanium, duplex, super duplex and special alloys and materials.
Highly qualified personnel carry out control activities using inspection and testing systems and up-to-date procedures. The use of control instruments capable of preventing the waste of materials and time is also fundamental. “In recent years,” Stefano Marelli explains, “many of our clients have started requesting fasteners with increasingly strict tolerances to be used on parts with shapes and dimensions that are very difficult to measure. With traditional measurement instruments, it was extremely laborious to check measurements and concentricity, planarity and linearity rations on elements that are so small and, at times, also difficult to reach. We also tried out other types of solutions, such as mechanical sensors and probes, but we were never completely satisfied”.
Stampinox therefore decided to acquire a more technologically advanced instrument, the FARO Edge portable coordinate measurement machine (CMM). Stefano Marelli explained: “We have found the FARO Edge to be the ideal instrument to meet our needs. It is capable of easily checking product quality using 3D inspections and measurements, dimensional analysis and CAD comparisons. It is also much more flexible than other 3D measurement devices: it can be used in the metrology room as well as on-machine right in the workshop. This last feature is particularly useful and convenient, since it enables us to speed up in-process as well as end-of-process controls. That saves us precious time.”
The FARO Edge measurement arm uses next-generation technology to guarantee top-of-the-line performance and reliability. Users will also find the device even simpler to use due to its integrated computer touchscreen. Stefano Marelli continued: “It was quite straightforward to begin using the measurement arm at our company. The FARO technicians who worked alongside us during the initial period of training and support helped us to appreciate how easy it is to use. It is no coincidence that the FARO Edge is used not only by measurement personnel, but also by other non-specialist staff.”
Today, about one year since it was purchased, the FARO Edge has become an indispensable tool in the Stampinox workshop. Stefano Marelli stated: “When it comes to verifying tolerances in particular, this instrument provides extremely high levels of repeatability and accuracy, fully in line with the objectives we had set for ourselves. However, it is especially the measurement acquisition speed that has left us absolutely satisfied: with the FARO device, the speed of control operations has increased considerably, typically by around 20-30%.” To sum up, as confirmed by Stefano Marelli, this device has turned out to be an important and crucial investment for Stampinox: “The FARO Edge has allowed us to take a significant step forward, as it enables us to sell complex products that we previously had the technical capability of manufacturing, but were not able to measure adequately.”
Machined parts have long been reserved for industrial markets. However, they have recently started being used in the construction industry to meet the demands of architects who are continually pushing the boundaries in both their architectural designs and their choice of materials. As a result, building professionals must find different ways of working, breaking their habit of making on-site adjustments, which would be impossible (as machine tools are not portable) or extremely costly for these kinds of parts. Cambium – an industrial company that has diversified into the construction industry – has understood this change perfectly, as Thomas Mermillod, Head of Research and Development at the company, explains: “It is essential for the parts to fit together well, which means it is necessary to have a very precise knowledge of the topography of the site and to position the first pieces with a high degree of accuracy. With the Focus3D laser scanner and FARO Laser Tracker, we are able to meet this challenge.” While new construction is not simple, renovation projects are even more complicated as the geometrical layout of the site is generally notprecisely known.
Cambium was recently faced with this situation when it participated in the renovation of the concert hall in the Maison de la Radio in Paris. Cambium was selected to manufacture and install the wooden panels of the 140 m2 acoustic reflector hanging from the ceiling in the hall. The company made 200 wooden panels, each one unique, with curved shapes and grooves of different shapes and widths. As sound quality is crucial for the reputation of a concert hall, it was imperative to respect every detail of the requirements set out by the acoustics experts (the Japanese firm Nagata Acoustics). “Without the Laser Tracker, we would not have been able to complete this project. We used the tracker to check the panels after manufacture and particularly when positioning the first panel, as this first element is crucial for the arrangement of all the parts of the structure. This long-range tool is very convenient to use: the camera was located on the ground and guided us as we positioned the panels 12 m above ground level. The tool’s range is also ideal for largescale projects, so we were able to work for an entire day without changing its position,” said Thomas Mermillod.
Cambium has been using the FARO Laser Tracker for eight years. The company uses it for the two main tasks for which laser trackers are employed – control and alignment aid. Initially, Cambium also used the tracker for scanning sites and buildings, which was a bit tedious because this required a point-by-point survey. As the Focus v laser scanner automatically creates a point cloud, things have become much easier. The tool proved to be invaluable in the renovation of the concert hall in the Maison de la Radio. It allowed Cambium to create a plan of the architecturally complex hall, which has almost no flat areas (vertical or horizontal) or angles, but many curves. “Another very important aspect of the FARO product range is that it is very easy to use the laser tracker and laser scanner within the same reference framework and using the same software (PolyWorks, in our case),” concludes Thomas Mermillod.

Okay, so the question is: what exactly is reverse engineering?
Reverse Engineering is the process of duplicating an existing product without the aid of drawings, documentation, or computer models.
Normally the product designer creates a drawing showing how an object is to be built and then the object is manufactured by following the design drawing.
However, with reverse engineering the steps are inverted and the object is ‘reverse engineered’ to discover its structure, function and operation. Therefore, duplication of the part is enabled by capturing physical dimensions, features and material properties.
The FARO ScanArm is a portable CMM ideally suited for reverse engineering applications. One key advantage of using the ScanArm to inspect is that soft, deformable, and complex shapes can be easily inspected without coming into contact with the part, greatly reducing the risk of damaging the item.

Modern-day challengers have a clear benchmark against which to measure their skill and ingenuity. The World Water Speed Record is the pinnacle of sporting achievement on water – a compelling contest by man and machine, played out on a backcloth of wind and wave, distance and time.
The current record of 317.60 mph was set by Australian Ken Warby, in Spirit of Australia on the 8th of October 1978, at Blowering Dam Reservoir, NSW, Australia. Although this impressive mark has been challenged on several occasions, the record has now stood resolute for more than 36 years.
With the objective of bringing the Water Speed Record back to the UK, author Nigel Macknight established the ambitious Quicksilver project. Now, after much development work, experimentation and in-depth trials, an extremely efficient boat design has emerged.
With the help of the FARO Edge ScanArm HD data has been gathered relating to all of the Quicksilver boats external surfaces. The rapid capture of precise data will help to expedite the penultimate stage of the project. The FARO Edge ScanArm HD combines the flexibility and the functionalities of a FARO Edge measuring Arm with the high-definition Laser Line Probe HD creating a powerful contact/non-contact portable measurement system ideal for challenging application requirements, such as In-Process Inspection and Automotive.
