What is 3D Scanning – How It Works – Should You Buy It?
How Does It Work?
3D scanning is the first step of 3D printing. There are two typical ways to 3D print firstly you can manually design your desired shape or design and another way you can scan any object you want to print then you have to give a final touch with some 3D scanning software that we will talk later. Well if you are interested in 3D printing and 3D scanning let’s answer all your question in a nutshell.
What Is 3D Scanning?
3D scanning is the process where real-world object scanned by 3D scanner. It collects data and recreates an original shape into a digital shape thanks to the 3D scanner it now becomes a 3D object. It will help us in the future when we want to print this object with any 3D printer. But don’t worry if want to edit this object and modify the object you also can do it with 3D designing software. There are a number of possible ways to print your object and scan your object but today I will talk about three of them. photogrammetry, and structured light scanning. Choice any of them regarding your requirement of the project.
How Does 3D Scanning Work
Laser 3D Scanning
3D laser scanning technology is non-violating and non-destructive technology. It captures a digital image(shape) of an object using a line of the laser. 3D scanners able to measure really fine details and it creates a shape with “point cloud” we can say 3D printer able to capture the exact size and shape of real-world object. 3D laser scanners calculate fine details and catch free-form shapes to create extremely accurate point clouds rapidly.
3D laser scanning is perfectly suited for the calculation and analysis of contoured structures and complex dimensions requiring massive amounts of data for their accurate description and where this is impossible using conventional measuring methods or a contact detector.
Photogrammetry is the use of mapping and visualization of photos. It is used to calculate the distance among objects, and applications for photogrammetry can use pictures to create 3D renderings. Although it was mostly used for topographic modeling in its early days, it has been used frequently in a variety of unexpected ways. It seems pretty simple, no? This method uses the parallax obtained between several pictures, taken from different points of view.
This is the tool used to turn many images into a specific 3D model. This won’t allow you to get the most accurate result, but you could actually achieve a satisfactory result by using good photogrammetry technology!
Structured Light Scanning
A structured light scanner’s fundamental task is simple: You projected a structured pattern of light onto a target, then film it with at minimum one camera (usually two cameras) to catch how the subject refracts light the pattern of light. You can measure the item’s measurements in all its form by triangulating several scan frames.
How Does it Work?
If you just want to replicate an actual object, 3D scanning can be a faster and easier method to construct a 3D model for 3D printing. You can apply the changes to it once you have your 3D template, it can certainly be a good base for beginning your design.
What are these 3D scans applications? This imaging technology is really doing the most of the medical sector. It also helps to create created from 3D scans for clinicians to calculate prothesis. In the dental industry, for instance, the use of 3D scanners is already quite common for analyzing, simulating options or even designing certain dental products, such as braces, implants and dentures. Use 3D scanning or 3D printing is ideal to remove all the molds drawbacks and the whole production method.
