3D Is Becoming Increasingly Popular – Is a 3D Scanner Right for You?

3D scanners are becoming increasingly popular and essential tools across many different industries. So, what is a 3D scanner, what are the challenges of using one, and what are the factors you need to consider when choosing a 3D scanner? This article will deeply analyze these aspects to help you gain a clearer understanding and make the right choice for your practical needs.

What is a 3D Scanner and Its Practical Applications

A 3D scanner is a high-tech device used to digitize real-world objects into digital three-dimensional models by collecting data on the object's shape, size, and surface. This technology uses a laser or structured light source projected onto the object; sensors then capture millions of data points to create a point cloud for accurate 3D model generation.

The applications of 3D scanners are wide-ranging and rapidly developing. In manufacturing, they aid in rapid prototyping, quality inspection, and reverse engineering for more precise component fabrication. The architecture and construction sectors use them to recreate the current state of a structure, supporting the preservation or upgrading of historic architecture. 3D scanners are also applied in coordinate measurement in the shipbuilding industry and for quick repair of damaged parts.

Challenges When Using 3D Scanners

Although 3D scanners offer many benefits, you must be aware of the practical challenges in their use. Lighting is a crucial factor; dim or uneven lighting environments reduce the quality of the scanned data. Certain materials, such as highly reflective, transparent, or dark surfaces, can challenge the sensors. Furthermore, the complex size and shape of an object can sometimes create gaps or data omissions during the scanning process.

Hardware requirements for the computer are also something you need to consider carefully to process large volumes of data quickly and efficiently. Some 3D scanners are still not truly convenient in terms of mobility or ease of use, requiring the operator to have a certain level of technical knowledge to operate the equipment and modify the models. The selection of accompanying software is equally important, as it determines the capability to process and utilize the 3D scan data.

Key Factors to Consider When Choosing a 3D Scanner

When selecting a 3D scanner, you should focus on technical factors such as accuracy, scanning speed, maximum and minimum scanning volume, the ability to scan diverse materials, and data output formats to match your usage needs.

For instance, the Shining3D EinScan-SE Desktop 3D Scanner stands out with an accuracy of up to ≤0.1 mm, a fixed scanning volume of up to 700×700×700 mm, and a fast scanning speed (less than 8 seconds in fixed mode). It supports multiple data formats like OBJ and STL. It is suitable for creating detailed models of prototype products, quality inspection, or reverse engineering.

The INSIZE and Cognex scanners are also highly regarded options, with various models ranging from handheld to fixed, offering flexibility for tasks from industrial metrology to product inspection. Portability and ease of use are also a concern for many users, especially with handheld scanners like the EinScan Libre from Shining3D, which helps minimize preparation time and increase field work efficiency.

The 3D scanner is becoming an indispensable tool in many fields, offering the ability to accurately recreate models and providing a variety of practical applications. Although some challenges remain, such as lighting conditions, specialized materials, and technical operating requirements, by choosing the right 3D scanner, you can fully and effectively utilize this technology.
