Did you know that the 3D scanning market value was over $45 million in 2020? This shouldn't come as a surprise given all of the utility a 3D scanner can provide. Some of the most notable benefits include taking accurate measurements and making detailed documentation.

With so many options for 3D scanners, though, it can be difficult for you to choose the one that's best for you. In this guide, we'll go over everything you need to know when buying 3D scanners, as well as the factors you need to consider when making your decision. So, let's get started!

 

Resolution

One of the first things you'll want to consider when choosing a 3D scanner is the resolution.

Resolution refers to the smallest details that the scanner can pick up. For most scanning applications, you'll want a scanner with high resolution. This will ensure that all the details of your scan are captured accurately.

There are two main ways to measure resolution: voxel resolution and 3D point resolution. Voxel resolution is the number of cubes that make up a unit of volume in the scan. 3D point resolution is the smallest distance between two points that the scanner can detect.

For most projects, you'll want a scanner with high voxel and 3D point resolutions.

This will ensure that the scanner can capture all the details of your object. For those who use scanners for their company, the resolution is crucial. You will need the highest resolution possible to maximize customer satisfaction and scale your business.

 

Scan Speed

Another important factor to consider when choosing a 3D scanner provider is speed.

Some scanners are faster than others, so it's important to choose one that will meet your needs. If you need to scan large objects or multiple objects at once, you'll want a scanner with a high scanning speed.

If you're only scanning a few small objects, a scanner with a slower scanning speed will be adequate.

 

Size

The size of the 3D scanner is another attribute to keep in mind. Some scanners are bigger than others, so you'll need to make sure the scanner you choose will fit comfortably in your workspace.

Additionally, some scanners are more portable than others. If you need to move your scanner between different locations, you'll want a scanner that is easy to transport. Otherwise, it can be highly inconvenient to own.

 

Price

You should never neglect the price of your 3D scanner. Not all scanners are created equal, and you often get what you pay for.

That being said, you don't always have to choose the cheapest scanner. Sometimes it's worth spending a little more on a scanner with better features. Under the right circumstances, it will pay for itself as you continue to use it. You can also check online customer reviews to get a feel of what you can expect.

 

Accuracy

Accuracy is another key factor to consider when choosing a 3D scanner. The accuracy of a scanner refers to how close the scan is to the actual object.

If you need a high degree of accuracy for your scan, you'll want to choose a scanner that's advertised as having outstanding accuracy. If accuracy is less important to you, you can choose a scanner with a lower degree of accuracy.

This can be great for situations where you need to complete as many projects as possible within a short period. Creating mockups, for example, is a scenario where accuracy is not as important as speed.

 

Understanding Conventional Accuracy Vs. Volumetric Accuracy

When looking at 3D scanners, you'll often see two different types of accuracy mentioned: conventional accuracy and volumetric accuracy.

Conventional accuracy refers to the accuracy of the scan in terms of its shape. Volumetric accuracy, on the other hand, refers to the accuracy of the scan in terms of its volume.

Generally speaking, volumetric accuracy is more important than conventional accuracy. This is because the volume of an object is what determines its weight, and therefore its cost. So, if you need to know the weight of an object for shipping or manufacturing purposes, you'll want a scanner with high volumetric accuracy.

There are a few different factors that can affect the volumetric accuracy of a scanner. The most important factor is the number of points that the scanner can capture. A scanner that can capture a large number of points will be highly accurate. Other factors that can affect both types of accuracy include the scanning speed and resolution of the scanner.

 

Field of View

The field of view (FOV) is the size of the area that the scanner can see.

The bigger the FOV, the more area the scanner can cover. If you need to scan large objects, a scanner with a large FOV is your ideal option.

If you only need to scan small objects, you can get by with a scanner with a smaller FOV. Some scanners also offer a 360-degree FOV, which means the scanner can scan objects from all angles. This can go a long way toward making your scanning project easier to complete.
