3D scanning is an unknown world for you? You don’t know the advantages of using this service in your company? Let us briefly introduce you to 3D scanning and its multiple possibilities.
3D scanning is a process that allows you to measure objects with great precision using a 3D scanner.
It should be noted that there are several types of scanners. However, it is possible to divide those currently used in the industry into two broad categories:
The first type of 3D scanner, the portable high precision scanner, is, as its name indicates, a device that can be carried almost anywhere, in order to perform a 3D scan of a part with a high degree of accuracy. The device emits a light source where laser crosses are projected onto the part to be scanned, allowing the creation of a mesh that very accurately represents the surfaces of the object. The size of the parts that can be scanned can be very small or very large, as long as accuracy is desired.
The types of applications for the ultra-high accuracy handheld 3D scanner are varied. It can be used in the case of reverse engineering, in order to accurately reproduce an existing part, either because it is discontinued, or, a common problem these days, the delivery times to get the desired part are very long. It is also possible to use this scanner in the case of the inspection of parts, either to confirm the manufacture before installation by comparing the scan and the model, or to check a flatness or even wear of an object. In short, the strength of portable 3D scanning is the accurate reproduction of parts that are difficult to measure or the inspection of an object that needs to have some accuracy.
The parts must be clean and dry to perform the scan. For example, if there is grease or dust buildup on the object, they will get scanned, which will take away the accuracy.
At FORCETECH CONSULTANTS, we have a HANDYSCAN BLACK ELITE OF CREAFORM. It is one of the fastest and most accurate devices on the market, with an accuracy of 0,025 mm (0,0009 po). We also have maxSHOT 3D, which when used with HandySCAN, keeps accuracy on large objects.
These are examples of projects that have been completed by our team with HandySCAN :
The second type of scanner, and the most used in our case, is the scanner 3D à balayage laser. This scan is referred to as long-range, since it allows for large-scale scans. The device works by emitting laser pulses that generate a point cloud with each scan. The combination of all the point clouds reconstructs the volume of the non-contact environment. This type of scanner is used for very large rooms, as well as for complete environments, such as a room, part of a factory or an outdoor yard, etc.
The types of applications for the long-range 3D scanner are numerous. Whenever equipment, structure or piping needs to be installed in an existing location, the laser scanning 3D scanner is the tool of choice. With the entire existing environment available, it is easy to plan where new equipment will be installed, while avoiding potential conflicts. It is also possible to do monitoring with the long range 3D scanner. By taking scans on a regular basis, it is possible to compare the evolution of a tunnel, a tank or a building in space for example. Volume evaluation is also very easy with this equipment, especially for ore reserve evaluation.
This scanner can also be used for reproduction of very large parts where the required accuracy does not require the use of the high accuracy scan. However, it is possible to combine data from both types of scanners, in order to have increased accuracy on certain parts of large parts. In short, with 3D scans, the possibilities are almost endless.
Chez Forcetech Consultants, we have a RTC 360 de Leica. Again, this is one of the best and fastest devices on the market today. With a measurement rate of up to 2 million points per second, creating HDR images and creating a color point cloud cant can be done in just 2-3 minutes.
It automatically locates itself in space with these many cameras, creating the links automatically between stations. Using the field application also allows you to see real-time data acquired by the device. The RTC 360 has a range of 0.5 m to 130 m, as well as an accuracy ranging from 2 mm to 6 mm depending on the range.
We also have at our disposal a boom system with a counterweight that allows us to scan vertically, as well as a tripod with a height of up to 15 feet. This equipment allows us to perform scans in hard-to-reach locations.
