We’ve listed the top three things you must know before buying a 3D scanner in this blog post to make a profound decision!

3D printers are capable of producing the item you’ve designed. However, scanning an existing item and replicating it with a 3D printer is easier. Furthermore, 3D scanners can scan existing parts, hand sculpted models, and the human body to design authentic products to complement them.

3D scanners can also be used to check the accuracy of 3D-printed parts. This provides a clear business case for 3D scanners, but it is unclear which of the primarily available 3D scanners could be your perfect choice. You need not worry because we’ve listed the top three things you must know before buying a 3D scanner in this blog post to make a profound decision!

Cost versus Accuracy

In general, the lower the accuracy, the lower the price. Most 3D scanners employ an offset camera to triangulate points on an item, but they vary in how the points are generated. The structured light scanners are more accurate than laser scanners. This is because they do not create the noise generated by the laser speckle pattern. Details less than the resolution of the scanner will not be recorded.

In certain circumstances, speed and accuracy are more important than precision. High resolution is critical in reverse engineering applications. Low resolution is acceptable when scanning and printing products on a low-cost consumer printer.


Expect to spend more on a 3D scanner as the size increases. Don’t settle for poor resolution or waste time while attempting to collect 3D data with a scanner that is too tiny for the task.

Don’t forget to factor in the volume. Desktop scanners can scan an item on the turntable, but only as high as the scanner can be lifted. Tall, slender objects cannot be adequately scanned as a result. Handheld 3D scanners have fewer size limits since they may be physically maneuvered around the object. A portable 3D scanner, for example, is generally the ideal option if you want to scan an entire room.

The Desired Application

Do you need to scan objects very instantly? In most cases, handheld 3D scanners are the best option. Because they cannot sit still, portable scanners are ideal for assessing someone’s spinal curvature. Because they scan patients and their surroundings swiftly and conveniently, handheld 3D scanners are perfect for medical and ergonomic applications.

A single-axis turntable is suitable for scanning vases and other simple objects. If the things you’re scanning include recessed and angled features, a multi-axis turntable that tilts the object is preferable. This guarantees that angles and curves obscured when the object is scanned on a single axis are captured. If you don’t perform this when required, you’ll overlook essential characteristics in the scan.

To put it all condensed, if you’re scanning materials with deep relief, a multi-axis turntable or portable 3D scanner is required. Is it the intention to scan sites such as sets and ground cover? The best option is to use handheld scanners.

3D scanning makes it possible to acquire the data required to generate three-dimensional models swiftly. The best 3D scanner, however, can only be determined based on the application and the scenario.
