Handheld & Stationary 3D Scanner Comparison

August 22, 2024

Summary. Handheld vs stationary 3D scanners differ in accuracy, resolution, and portability. While stationary scanners provide high-resolution images, handhelds offer flexibility and portability. Consider usage needs for the best choice. Consult professionals for handheld 3D scanner comparison insights.

When it comes to choosing between a handheld and stationary 3D scanner it is important to consider the ways in which you will use it. Then, you will have a better understanding of which device will best suit your needs. Here, we will discuss the comparison of handheld and stationary 3D scanner. We’ll also discuss their uses and how they can adapt to suit your projects.

You can see Central Scanning’s full range of 3D scanners here – both stationary and handheld.

Stationary 3D Scanner

As the name suggests, a Stationary 3D Scanner is mounted in one place and is fixed to that location. Instead of moving the scanner, you will instead carefully move the object you wish to scan. This is until you have finished capturing all the different angles and positions of the object. Similar to how panoramic photographs work, each scan will merge together at the end to create a ‘full picture’ 3D digital model of your object.

Handheld 3D Scanner

The handheld scanner works in a similar way to its stationary counterpart but acts as more of a video camera. The user must continuously be moving around the object so that it is able to create an overall digital scan of the entire object until every digital detail you desire is captured.

What are the differences between the two?

It may appear that there isn’t much to differentiate these two scanners. There are in fact a number of factors which affect their usability and performance in varying situations.

Accuracy & Resolution Of Image

The most obvious difference would have to be the level of accuracy and the resolution of your final digital image. A stationary scanner will always be able to pick up detail and shape with increased accuracy which will ultimately create a high-resolution image. This is primarily down to how each scanner take a snapshot of the object. A stationary scanner will take many snapshots in one scan and then combine each to create the average shot of that scan. Conversely, the handheld scanner will take a single snapshot and use that image as the shot for the scan.

You may also find that handheld 3D scanners have more capability when scanning hard to reach areas. Therefore, helping you create a more accurate and detailed overall digital design of your object. It is easy to manoeuvre and can quickly scan large areas of an object. That being said, stationary scanners can also scan large objects by simply moving it forwards or backwards to increase the lenses’ field of view.

Battery Life & Off Site Capabilities

There are however aspects of the stationary scanner’s design that are arguably more user friendly. An example is how portable it is. If you are looking to scan objects away from a computer, the handheld scanner can provide you with hours of battery life. This allows you to scan wherever and whenever. It can also be hooked up to a tablet on the go, making it even easier to use off site. Stationary scanners would never have this capability as they require a constant stream of power to successfully run.

FAQ: Choosing Between Handheld and Stationary 3D Scanners

What should I consider when choosing between a handheld and stationary 3D scanner?

When deciding between handheld and stationary 3D scanners, consider how you plan to use the device. Factors like portability, accuracy, resolution, and the nature of the objects you need to scan will play a significant role in determining the best fit for your needs.

How does the accuracy and resolution of handheld and stationary 3D scanners compare?

Stationary 3D scanners generally provide higher accuracy and resolution due to their ability to take multiple snapshots from a fixed position. These images are then combined to create a detailed, high-resolution digital model. Handheld scanners, while slightly less precise in some cases, offer greater flexibility and are excellent for capturing hard-to-reach areas and scanning larger objects quickly.

Are handheld 3D scanners more portable than stationary ones?

Yes, handheld 3D scanners are designed for portability and can be used on-site with ease. They typically offer hours of battery life and can be connected to a tablet or mobile device, making them ideal for scanning in various locations. Stationary scanners, in contrast, require a constant power supply and are better suited for environments where mobility is less of a concern.

Can stationary 3D scanners capture large objects effectively?

Stationary 3D scanners can capture large objects effectively by adjusting the distance between the scanner and the object to widen the field of view. While they excel in detailed and precise scans, they are generally less flexible than handheld scanners when it comes to scanning objects in different locations or from various angles.

Which type of scanner is better for scanning hard-to-reach areas?

Handheld 3D scanners are typically better suited for scanning hard-to-reach areas due to their maneuverability. They allow users to move around the object and capture details from various angles, making them ideal for scanning complex shapes and surfaces.

Why consult a professional when choosing a 3D scanner?

Consulting a professional can help you understand the capabilities of each scanner model and ensure that you select the right device for your specific needs. A knowledgeable provider like Central Scanning can guide you through the decision-making process, offering insights into how different scanners perform in various applications.
