3D scanning technology has taken over the industrial world in a short while because of its unparalleled capabilities. The process is quite simple to initiate. It also takes a fraction of time to process all kinds of unique geometries with relative ease.
All 3D scanners operate similarly, but the scanning methodology it uses can have a significant impact on the results. The two most common types of 3D scanners available in the market today are 3D laser scanners and structured light / blue light scanners. In this article, we’ll go through the basics of 3D laser scanning and discuss its applications.
What is 3D Laser Scanning?
3D laser scanning is a non-destructive method of creating digital replicas of physical objects with the help of hardware and software tools. The technology uses a laser pointer or a laser line to cover each surface and translate the data in the cartesian plane (x, y, and z coordinates), which is then processed by the computer and converted into a CAD-friendly format. 3D laser scanners usually deal with over a million data points in a single scan. The process is accurate and can even process the most complex geometries without needing any special considerations.
3D Laser Scanning Services
The 3D scanning process is not complicated, and in many cases, it is a cost-effective option as well. However, you’ll need to invest a considerable amount in an industrial scanner, associated software, and other resources to get started. Spending so much is not an option for many startups and businesses that occasionally use this technology.
For such businesses that use the technology for reverse engineering, inspection, or any other reason, it is smarter to opt for a 3D scanning service that can perform the scan and deliver a digital file. 3D laser scanning is quite versatile, so you won’t have to make any special preparation (except a few tweaks). A reliable 3D laser scanning service can carry out the scan and deliver results in a single day. You can even ask for design changes and other services, as most 3D laser scanning services will have a CAD department as well.
For 3D scanning services as well, the business is both scalable and productive due to the versatility of this technology. 3D laser scanning has countless applications across several industries, and a 3D scanning service can cater to all their requirements without making any significant changes.
Applications of 3D Laser Scanning
A distinctive quality of 3D scanning is its versatility. Unlike many other methodologies, the scanning process and result quality remain constant irrespective of the application or industry. This adaptability is among the most prominent reasons why 3D scanning has become so popular across various industries in such a short time.
We have compiled a few industrial areas where 3D scanning plays an integral role.
- Design Engineering
- Simulation and analysis
- Maintenance and inspection
- Academia and research
- Entertainment and AR/VR
- Archeology and art
- Medical applications
The applications of 3D laser scanning go beyond the above list. The technology is developing at an unprecedented rate, and a lot of new industries are continually adding 3D scanning to their processes.
Benefits of 3D Laser Scanning
1 – Fast and Accurate
Compared with any other measurement method, 3D scanning is both fast and accurate. Not only that, you directly get a digital replication of your design in real-time. A single 3D scan usually collects numerous data points, which allows it to deliver the results with the utmost precision and consistency. Regular 3D scanners have a tolerance of few millimeters, and it gets further refined if you go for a superior industrial model.
2 – Adaptable and Cost-effective
Another excellent quality of the 3D scanning technology is its adaptability. The same set of equipment and software tool has the capability of catering to the needs of various industries. For prototyping businesses and other similar environments, 3D scanning is also a cost-effective option. Apart from the initial cost of purchasing a scanner and the associated software, you won’t have to spend so much money.
You can even avoid the initial purchase costs by approaching a reliable 3D scanning service like Tangent Solutions. Here’s a guide to help you get the best price.
3 – Delivers Comprehensive Results
Another benefit of using 3D scanning, especially for reverse engineering and design applications, is the technology’s ability to conduct detailed scans. Many engineers have had the experience of measuring the object again for extra details. 3D scanning eliminates this issue because the scans register all the data in a single go.
4 – Suitable for Production
For managers and business owners, continuing operations without breaks is a crucial job. Production breaks can cause unexpected delays, which can cause several other problems down the line. It’s one of the reasons why companies focus so much on preventive maintenance and other best practices to ensure reliability in crucial times. With 3D scanning, maintenance professionals can inspect key components without shutting down production and rectify issues proactively.
5 – Safe and Reliable
Building on the last point, 3D scanning also has the potential of improving the safety standards in a production environment. In many industrial applications, maintenance of machinery is quite hard due to the harsh conditions, which is risky and unsafe for human operators. For such cases, you can integrate 3D scanning technology in modern robots to carry out the job reliably without endangering human life.
Other 3D Laser Scanning Technologies
3D laser scanning is not the only technology that allows you to recreate objects, assemblies, and terrains digitally. There are multiple other methods of doing this job, but the following are the most popular.
1 – Structured Light 3D Laser Scanning
Both structured light scanners and 3D laser scanners use the same principles to create 3D scans. The only difference is in the wavelength and geometry of the light beam. Both technologies are so similar that some experts do not consider them different. However, the results and acceptable operating conditions of structured light scanners are better than their laser counterparts.
Instead of a laser line or a pointer, structured light scanners cast a fringe pattern on the object and registers deformations in it to create a data cloud. Structured light scanners are more accurate and versatile than 3D laser scanners. Blue light scanners can also work in well-lit areas, which is impossible for 3D laser scanners.
2 – Photogrammetry
Photogrammetry is another popular method of creating digital scans that focuses more on realism than accuracy. The technology uses several photographs of an object from all sides and uses their overlap to recreate a digital model.
Photogrammetry is a perfect choice for geological applications and terrain mapping. You can also combine photogrammetry and 3D scanning for large-scale applications. To know more about how industries are using photogrammetry and 3D scanning, check out this article.
3 – Contact Based Scans (CMM)
When compared to 3D scanning, this method has been around for a while and uses a probing machine called a coordinate measuring machine. In the CMM, a contact probe goes through the entire surface and transfers the data in cartesian coordinates. The output data of a CMM is quite different than 3D scanners, but you can use bot technologies interchangeably for quality control and inspection. You can’t use CMM for other applications where you need a CAD file or an STL file.
