10 Reasons Why 3D Scanning Is Useful for 3D Printing

3D scanning is a non-contact, non-destructive process used to capture the shape and dimensions of real objects or environments. Utilizing lasers and cameras, this technology collects detailed data that can be transformed into high-precision 3D models for a variety of applications. Before exploring the specific uses where 3D scanning excels, let’s take a brief look at how the scanning process works.

The scanning process itself utilizes various technologies and devices, which we will delve into later in more detail. Regardless of the technology employed, the scan involves capturing data from multiple positions and angles to create a comprehensive model of the entire object. This data is then utilized by CAD technicians to generate 2D drawings or 3D models. These models serve numerous purposes such as analysis, design planning, inspection, archiving, or creating new objects—showcasing the diverse applications of 3D scanning. Let’s now explore why you should consider 3D scanning and the benefits it offers for 3D printing.

3D scanners are imaging devices that create a virtual 3D model of a real object by measuring it. The devices use various technologies. The scanning process can be carried out using laser scanners, structured light scanning or photogrammetry, for example. Laser scanners usually use LiDAR technology (Light Detection and Ranging), which emits pulsed light waves that are reflected by the objects to be scanned. Software classifies the data obtained and 3D models are created using the resulting data point clouds.
