3D scan technology is something that is used in hundreds of industries across the entire world. In fact, we wouldn’t have many of the products and services that we have today without it.
But, how does 3D scan technology function? We’ve got all the information that you need to know. Let’s dive in.
So, What Exactly Is 3D Scan Technology?
As the name might suggest, 3D scanning involves collecting specific data from a physical object in order to determine the amount of space that it takes up. After this information has been procured, users are then able to digitally analyze the object and determine certain attributes.
From here, they can use this data to increase both efficiency and quality.
What Are the Different Types?
3D scanning occurs in a large number of different environments. This means that there are different types of 3D scanning better suited for some situations than others.
Let’s explore some of the most commonly seen.
This type of 3D scanning makes use of lasers in order to identify the location of certain data points through triangulation. A laser is projected onto the surface of the object and the shape of the line that it produces is observed by cameras.
The scanner is calibrated in such a way that the device is fully aware of the positions of both the laser and the cameras.
This is what allows accurate triangulation to be possible. Interestingly, this technique loses some of its efficacy when scanning shiny objects or those with transparent surfaces.
Although the name may not imply so, structured light 3D scanners also make use of triangulation. This method uses data collected from both the laser and camera sensors to determine precise XYZ coordinates.
This makes it a highly efficient form of 3D scanning that is applicable in a large number of circumstances.
Additionally, structured light 3D scanning is notably efficient and is both smooth and continuous during operation. The color of the light used also has an influence on the results.
Depending on your needs, you may prefer to use blue light instead of white light since blue light has a narrower wavelength. This allows blue light to collect smoother, more accurate results.
It should come as no surprise that contact-based 3D scanning is a bit more physically involved than the previously mentioned methods. During contact-based scanning, a probe is used that makes contact with the surface of the object.
This tool is often manually operated in order to procure the most accurate results. As you might guess, this type of 3D scanning takes much more time than other methods and often produces less precise information.
This type of 3D scanning comes into play when a user wishes to extract dimensional information from a photograph. Although this 3D scanning is able to produce highly accurate results on its own, it is often used in conjunction with other methods for comprehensive analysis.
It functions by utilizing a camera to take multiple two-dimensional photos in order to develop a data set for three-dimensional results. So, this is something that you should keep in mind when determining which is the right type of scanning for your needs.
What Is It Used For?
Put simply, the applications for 3D scanning technology are virtually unlimited. Not only does it allow professionals to achieve results far more efficiently, but they can also accomplish tasks that would be otherwise impossible or impractical to do by hand.
For example, a mechanic can quickly determine the dimensions of a tool or parts without having to dismantle it. Let’s briefly explore scenarios in which 3D scanning technology is used.
One of the most popular uses for 3D scanning is reverse engineering. To elaborate, you can scan a finished product in order to derive a three-dimensional model of the object.
You can then analyze this information on a computer and freely manipulate it.
Since you can achieve such accurate results, you can then reverse engineer the structure behind the object. This will allow you to obtain powerful insight into how it was created and how it can be improved.
Interestingly, many professionals are apprehensive when it comes to integrating 3D scanning technology due to how much it costs. But, the benefits far outweigh the money that you will need to invest.
For quality assurance purposes, 3D scanning is irreplaceable. You can reduce waste, minimize costs, and make small improvements in order to achieve the best level of quality possible.
This is particularly useful in industries where optimum efficiency is a necessity, such as aerospace engineering.

Since 3D scanning allows you to digitally manipulate an object, it is ideal for product design. In fact, it is highly difficult or impossible in many circumstances to achieve the same results through other methods.
Additionally, 3D scanning often provides professionals with unique insight into how a particular object or tool functions. With this information, they can then improve or modify the object in order to achieve better results.
