Affordable low cost 3D scanners are available in the market. These affordable 3D scanners are used by hobbyists, educators, students and freelancers for personal use.

In this article we will discuss applications of 3D scanner, How to select a 3D Scanner? and the best affordable low price 3D scanner available in the market for real world object scanning applications.

Why 3D Scanners are used?

Most affordable 3D scanners available in the market are used for scanning 3D objects and manufacturing them using a 3D printer. But in a real world 3D scanning has a vast variety of applications in engineering, entertainment and robotics. Following are the applications of 3D scanners in various fields.

  • 3D scanning is used for reverse engineering and inspection of manufactured parts in mechanical engineering.
  • Scanning and 3D printing real world objects.
  • Used in the entertainment industry for creating video game or movie real world characters.
  • Environment mapping in robotics.
  • Create 3D objects for Augmented Reality and Virtual Reality app developments.

Types of 3D Scanner : Available 3D Scanning Technologies

Various types of 3D scanning technologies are available in the market. Each technology has its own advantages, limitations and applications. For example, some scanners work best with large objects whereas some 3D scanners are designed to scan small parts with precision and accuracy. Following types of 3D scanning technologies are available in the market.

  1. Laser Based 3D Scanner
  2. Structured-light Scanning
  3. Coordinate Measuring Machine.
  4. Optical 3D Scanning
Laser Based 3D Scanner

Laser scanners utilize a trigonometric triangulation method to accurately scan 3D objects and work best for short range applications. 

The laser based 3D scanners have following advantages.

  • Low cost and easy to use.
  • Glossy surfaces can be scanned.
  • Portable.
  • Minimal impact from environment light conditions.
Structured Light 3D Scanners

Structured-light scanners are also known as blue or white light scanners. Compared to laser based scanners, structured light scanners utilize white or blue light to generate object 3D surfaces using  triangulation methods. They also work best for short range applications. 

Structured light 3D scanners have the following advantages

  • Low cost.
  • Highly accurate.
  • Larger scan area.
  • Multiple lenses for small and large part scanning are available.
Coordinate Measuring Machine (CMM)

CMM machines utilizes a probe that is moved along part surface to generate its 3D surface. Mostly CMM machines are used to inspect part quality.

CMM inspection machines have following advantages:

  • Highly accurate
  • Small or medium range parts can be measured.
Optical 3D Scanner

Optical scanners utilize a set of cameras and other sensors to track and scan an object position relative to the scanning head. Most optical scanners are portable and used to scan large objects.

Optical 3D scanner has the following advantages.

  • Portable.
  • Large scan area.
  • Low cost.

Factors affecting the selection of a 3D Scanner?

As discussed above, various types of 3D scanning technologies are available in the market. Buying a most expensive scanner may not work best for you. Therefore it is recommended to analyze a 3D scanner on following parameters and take decision accordingly.

Part Surface Type and Finish

Not all scanners work for all parts. For example, a reflection based scanner does not work best on glossy or clear surfaces. To scan glossy surfaces using a reflection based scanner, part preprocessing is required.

Accuracy and Resolution Requirements

A 3D scanner price starts from a few hundred dollars and can go up to thousands of dollars. What differentiate them is the level of the details a 3D sensor can capture. For example, for manufacturing and quality control activities a highly accurate 3D scanner is required. Whereas for Augmented reality and gaming development less accurate 3D scanner will also work.

Object Size

3D scanners are available in various scan area capabilities. Therefore good practice to select a scanner based on the range of object sizes you want to scan.

Scanner Types

Various types of scanners such as : desktop, handheld, auto scan are available. Therefore a good practice is to decide scanner type according to the available infrastructure.

Application Type

It’s really important to know if the 3D scanner you are planning to buy is safe to use on living beings. For example, laser scanners can harm human eyes. Therefore if the application is to scan human or animal bodies. You should buy a scanner that is more safe for humans.

Best Affordable Low Cost 3D Scanner

Depending on technology used, bed size and accuracy a 3D scanner price may vary from a few 100 USD to thousands of dollars. Following is the list of affordable low cost 3D Scanners available in the market. Each scanner has its own advantages, limitations and applications.
