Getting Started With 3D Scanning

What Is 3D Scanning?

In 3d printing, 3d scanning is a critical first step. 3d scanning is the process of creating a digital model of a physical object. It involves scanning the object using a specialized sensor and then transforming the data into a 3d model.

This model can then be edited, printed or used in digital simulations.

Various Types Of 3D Scanning Technologies Available

A variety of 3d scanning technologies are available, with each having its advantages and disadvantages. Choosing the right type of scanner for the job is crucial. Below are some options:

  • Photogrammetry: Uses multiple photographs of an object and triangulates the position of each feature to create a 3d model. It provides high-resolution and accurate models.
  • Structured light scanning: Uses a structured light projector to project a pattern onto the object, which is then captured by a camera. It is quicker than photogrammetry but less accurate.
  • Laser scanning: Uses a laser to scan an object and create a point cloud. It is the most accurate scanning method but can be expensive.
  • Time-of-flight: Uses a sensor to emit a pulsed light and then measures the time it takes for the light to return. It is fast but not as high in accuracy compared to laser scanning.

Factors To Consider Before Choosing A 3D Scanner

Choosing the right 3d scanner is critical when it comes to acquiring the necessary level of accuracy and detail in the 3d model. Here are some factors to consider before choosing a 3d scanner:
