What is 3D Scanning used for?

In this article, we will look at the basics of 3D scanning and how different industries have adopted 3D scanning into their workflow. You will be amazed at the results people have achieved. It may open your mind to possible solutions for your business.

Before we get to carried away, letÂ’s go over a few points about 3D scanning.

What is a 3D scan?
A 3D scan is a virtual map of a model or part. It transfers the data into a point cloud or a mesh —the point cloud/mesh comprises of thousands of triangles or polygons. These shapes form a 3D map of the scanned item. No matter how intricate the part, every detail can be captured. 3D scan data opens up a world of possibilities.

What is 3D scanning?
3D scanning is a method of analyzing a real-world object. The scanner collects data, capturing the shape and size of the item, by taking multiple photographs of the item. It stitches the pictures together. Once the scan is complete, you have a 3D model of your part. It can be turned around and viewed at every angle.

What does a 3D scanner do?
A 3D scanner is similar to a camera. It captures the data point of objects within its view. It uses a structured light beam, and a camera to collect the data. It calculates how much the structured light beam deforms over the object. This data is what creates the scanned model.

How do you use a 3D scanner?
That depends on what you are scanning. Smaller items are best suited to a table-top scanner. Table-top scanners have a turntable and two cameras on either side of the turntable.

If your item is taller than 200mm, say a car bumper for instance. Then you would need a mobile scanner. A mobile scanner is ideal for parts that are in situ and cannot move. They would scan the entire object using data points. ItÂ’s a very accurate and speedy way to collect data.

What is 3D scanning used for?
3D scanning data is used for a multitude of reasons. If you want to 3D print an object and you donÂ’t have a 3D model, you will need to scan the item. To reverse engineer a product, you will need a 3D scan of the object. To design a mating part, its so helpful to have the exact measurements of the original piece. Using 3D scanning technology makes this process much easier. It cuts down the number of revisions and improves the workflow. Saving businesses time and of course, money!

3D Scanning And Architecture
Architects need models of buildings and structures for several reasons, such as restoration or documentation. There are only two ways to collect this data – measure the building or 3D scan the building. As you can imagine 3D scanning, the building is a lot faster and more accurate. Can you imagine trying to measure every inch of an entire building?

3D scan data can be beneficial in the restoration process. You can see the exact condition of the building and what exactly needs repairing. If you have the right technology, there is no limit to what size building you can scan.
