3D scanning technology is an exciting and rapidly evolving field. There are many different types of 3D scanners available on the market, each with its own advantages and disadvantages. This blog post will give a detailed overview of three of the most popular 3D scanning technologies: laser scanning, structured light scanning, and photogrammetry.
1. What is 3D Scanning?
It is the process of using advanced technologies to create a three-dimensional representation of an object. This data can then be used to create a physical model of the object using a 3D printer or other manufacturing processes. 3D scanning can be used to create a detailed replica of just about any object, including people. 3D scanning technology is often used in the medical field to create accurate models of body parts, which can be used for surgical planning or prosthetic creation. It is also used extensively in the automotive and aerospace industries for prototyping and quality control.
There are a variety of ways to capture data for 3D scannings, such as using laser scanners, structured light scanners, or coordinate measuring machines. Each method has its own advantages and disadvantages, and the choice of which method to use will depend on the specific application. Once the data is captured, it can be processed to create various outputs, such as a 3D point cloud, a polygon mesh, or a CAD model.
Laser scanners
Laser scanners are devices that emit a laser beam and measure the reflected light to create a three-dimensional image of an object or environment. They are used in a variety of applications, such as 3D printing, surveying, and industrial inspection. Laser scanners work by projecting a laser beam onto an object or surface and measuring the reflected light. The data collected is used to create a three-dimensional image of the object or environment. Laser scanners are used in a variety of applications, such as 3D printing, surveying, and industrial inspection. They are also used for research purposes, such as studying the surface of Mars. Laser scanners are becoming increasingly popular as they offer fast and accurate results.

Structured light scanners
Structured light scanners are a type of 3D scanner used to create 3D models of objects. They work by projecting a pattern of light onto an object and then measuring the deformation of the pattern. This information is then used to create a 3D model of the object. Structured light scanners are used in a variety of applications, including industrial design, reverse engineering, and quality control. They are also used in medical and scientific research. There are a variety of different types of structured light scanners on the market. Some of the most popular brands include the Faro 3D scanner and the Artec 3D scanner.
Coordinate measuring machines
Coordinate measuring machines (CMMs) are highly precise tools used to measure the physical dimensions of objects. They are commonly used in manufacturing and quality control applications to ensure that products meet specifications. CMMs come in a variety of sizes and configurations and can be operated manually or with computer numerical control (CNC). CNC CMMs are programmed to follow a specific measuring routine and can be used to measure complex shapes or large numbers of parts with high accuracy. Manual CMMs are typically smaller and easier to use than CNC machines and are well suited for measuring smaller parts or for taking occasional measurements.
2. Advantages of 3D scanning technology
3D scanning technology has a number of advantages that make it an attractive option for many different applications. Perhaps the most obvious advantage is its ability to create highly accurate three-dimensional models of objects. This can be extremely useful for things like reverse engineering or quality control. Another advantage of 3D scanning technology is its flexibility.
Unlike traditional methods of measurement, 3D scanning can be used to measure objects of any size or shape. This makes it ideal for measuring objects that are difficult to access or have irregular surfaces. Finally, 3D scanning is relatively quick and easy to use. This makes it a great tool for capturing detailed information about an object without having to invest a lot of time or money.
3. Disadvantages of 3D scanning technology
There are a few disadvantages of 3D scanning technology to be aware of. Firstly, the process of 3D scanning can be quite time-consuming, particularly if you are scanning large objects. Secondly, the accuracy of 3D scans can be affected by the quality of the scanner and the environment in which the scanning takes place. For example, if there is too much light or movement during the scanning process, this can result in a less accurate scan. Finally, 3D scanning can be pretty expensive, depending on the quality of the scanner and the software required to process the 3D scan.
4. What’s the Future of 3D scanning technology?
The future of 3D scanning technology is looking very promising. With the rapid advancement of this technology, it is becoming increasingly affordable and easier to use. This means that more and more people are able to benefit from the technology.
It is used in a variety of different fields, such as medicine, architecture, engineering, and even art. The possibilities are endless, and technology is constantly evolving. One of the most exciting aspects is its potential for use in medicine. For example, 3D scanning can be used to create detailed models of organs and body parts. This can be extremely helpful for doctors and surgeons who need to plan complex procedures.
In summary, 3D scanning technology is a methodology used to make a digital model of an object, then convert that model into a digital 3-D model or image. Scanning an object is typically done on-site for immediate use, or at a lab for accuracy. The 3-D model or image can then be used in numerous ways, such as for digital design, engineering, and printing.
