The market for structural 3D scanning is growing exponentially as the advances in technology are making it more accurate and accessible. The market for 3D scanning products like blue light scanners is projected to be worth Billions in the coming years as it is supported by numerous industrial sectors ranging from aerospace and defense to construction. The popularity of 3D scanning indicates just how much of a game changer this technology is.

Traditionally, 3D scanners relied on lasers and white light to convert a physical model into a digital one. However, they could only be used on limited surfaces and had some issues related to accuracy. Blue light scanners are the latest solution that use structured light to successfully address the aforementioned problems and deliver exceptional results with consistency.

The Technology Behind Blue Light Scanners

To understand the operations of a blue light scanner, it’s imperative to know about the technology behind it. Finite Element Analysis (FEA) and triangulation are the building blocks of 3D scanners. The projector in a 3D scanner casts a fringe pattern on the surface you need to scan. 

3D scanners use internal cameras to register any distortions in the fringe patterns and map them out in a cartesian coordinate system. These distortions are then transmitted to a computer that uses the associated software to create a 3D model for other applications and further processing.

Structured light scanners are known for their accuracy because the object is scanned from different angles. The object remains stationary and operators move the scanner over it to capture every single surface. Generally, blue light scanners take only a few seconds to deliver results and are accurate to a 10th of a millimeter or more.

Why are Blue Light 3D Scanners Preferred Over Other Options? 

Blue light scanners are generally considered better than all the other options available in the market. Laser scanners and white light scanners are the most common alternatives, but their main problem is that they fail to reach the level of accuracy, versatility, and consistency ensured by blue light scanners.

The biggest problem of 3D scanning before structured light scanners was the light’s tendency to refract or get absorbed by the object. This property had a significant impact on the overall accuracy of the scan and operators had to conduct multiple scans of the same area to avoid such issues. Structured light addressed this problem by using fringes. 

In the past, structured light scanners relied on white light, which improved the accuracy and consistency of their results. However, white light was sensitive to heat and could still not process transparent or shiny objects accurately. You also had to dim all the other lights in the room to operate the scanner. Shifting to blue light solved all these issues. Blue light has a shorter wavelength which allows the scanner to operate in bright conditions. Similarly, blue lights are also less sensitive to heat sources and are slightly better at handling shiny objects. 

How does Tangent Solutions Use Blue Light Scanners to Maintain its Top-notch Services?

Tangent Solutions is committed to providing the best engineering design and scanning services to its customers by using the most powerful equipment available in the market. For 3D scanning, Tangent Solutions relies on the Creaform HandyScan Black Elite, which is one of the most powerful handheld scanners available in the market. The Creaform HandyScan uses a combination of industry-grade features and capabilities that make it a perfect choice for various professional applications like quality control, reverse engineering, and product design.

The HandyScan Black Elite comes with proprietary TRUaccuracy technology that comes with the volumetric accuracy of 0.02mm and a mesh resolution of 0.1mm. The scanner also comes with the VXElements 7.0 and LiveMesh tools, which immediately convert the scanned data into a suitable format for your CAD tool.

Tangent understands that speed is of paramount importance in many applications and offers a same-day delivery guarantee for many of its services. With the HandyScan Elite by Creaform, Tangent Solution can deliver excellent results in the shortest time possible. The scanning speed of HandyScan Elite is   1,300,000 measurements per second, which makes it about 60% faster than a standard professional 3D scanner without compromising on the accuracy.

When it comes to functionality, the Creaform 3D scanner leaves nothing to be desired. The powerful blue light scanner weighs 2.1 lbs (1Kg), which makes it easier to operate over long time periods. The simplistic design is quite easy to control as all the buttons are conveniently located at the top of the handle. The scanner also comes with a VDI/VDE 2634 Part 3 accreditation which is a gold standard for 3D measurement systems.

Tangent Solutions offers on-site inspection services to its clients as well. There are multiple scenarios where the object can’t be transported or you might need 3D scanning services to conduct repairs on heavy machinery. Creaform HandyScan Black Elite is perfect for such situations as it is both portable and powerful enough to handle the most complex job. This 3D scanner also remains unaffected by the lighting conditions, which allows our team to get started with the scanning process without disturbing your production facility.
