Today, modern 3D technologies have already gained recognition in various fields of human activity, and recently such technology as 3D scanning has gained particular popularity.

Scanning 3d objects allows you to get three-dimensional digital models of various physical objects in a matter of seconds. Ready-made models can be applied in medicine, construction and architecture, in the film industry, etc.

The use of a 3d scanner greatly speeds up and simplifies the process of obtaining a 3d model of an object, and also allows you to get the most accurate model.    

How do 3D Scanners work                       

A 3D scanner is a special device designed to collect and analyze data about a physical object, on the basis of which its three-dimensional model is then built.

When examining a physical object, a 3d scanner recreates its exact copy, realizing it in a 3d model of the object. A modern 3D scanner can be a small hand-held device or look like a larger stationary device that additionally uses a special lamp and laser as a backlight, which increases the accuracy of measurements.

The principle of operation of the device is determined by the scanning technology used in this case, in any case, the device needs to determine the distance to the object of study.

How to scan an object for 3d printing? In order to determine the distance to the scanned object, the scanner uses built-in cameras and special illumination, all measurements received by the device are recorded, and upon completion of the data analysis, a finished three-dimensional model is displayed on the screen.

The scanning process can also be performed using a laser beam moving over the surface of the object, taking all the necessary measurements. The coordinates of all measured points are recorded and, based on this information, a computer model of the object is built.

Types of 3D scanners By setting all the necessary parameters and resolution, you can get a higher detail of the finished object. Modern scanning devices make it possible to obtain ready-made three-dimensional models with an accuracy of several tens or hundreds of micrometers.

3d scanning of objects allows you to recreate not only the natural shape of the object, but also its color. The resulting three-dimensional image of the scanned object can always be adjusted to specific requirements and needs with the help of special computer programs for working with 3D graphics.

What are 3D Scanners used for              

An answer on the question how to 3d scan an object is simple. For the convenience and efficiency of 3D scanning of objects of various sizes and geometries, various 3D scanners are used.

  1. In the focus of attention are small detailed objects. The digitization of such products usually subject requires maximum measurement accuracy. Artec Space Spider 3D scanner is widely used for this. GOM 3D scanners are also used for this purpose.
  2. Next one group is medium-sized objects. Scanning of this category of objects, is carried out with hand-held 3D scanners. Artec Eva is great structured light choice to carry out this task.
  3. One more group is large objects (buildings, communications, trucks, etc.). Scanning large objects requires the scanner to read the form at large distances (0-300 meters). Scanners provide fast and accurate (~ 1 mm) construction of a 3D model of objects at distances from 0 to several hundred meters.
