Speed up Reverse Engineering of Impeller by 3D Scanner

Mar 18, 2020

With the continuous improvement of modern manufacturing technology and product design, products’ complexity and precision make manual measurement tend to be more difficult. Especially for some parts with complex structures and details, manual measurement easily produces accumulated errors so as not to obtain complete and accurate 3D data.

In recent years, 3D scanning technology has been widely used in various fields. 3D scanners have been favored by users because of their high accuracy, fast speed, simple operation and obvious portability.

The difficulty in getting 3D data of complicated object

There are various 3D scanners on the market. Generally, some of 3D scanners can handle normal objects without obvious features, but they have difficulty in conducting 3D inspection of hole, dead angles, complicated surface, etc. What kind of 3D scanner can be regarded as a satisfactory one when scanning object with many features like impeller?

What customer needs?

The manufacturer hopes to optimize product development based on precise 3D data and eliminate deviations. Reverse engineering is used for hardware analysis, the main purpose is to analyze the design principles directly from the finished product when we can’t easily obtain the necessary production information.

ScanTech 3D Solution

Impeller is usually designed with narrow gaps, which forms obstacles to conduct 3D measurement from different angles and capture complete 3D data.

A high-precision PRINCE 3D scanner, with red and blue laser scan working mode, is widely applied in product development, reverse engineering, quality control, reverse engineering and others. This 3D laser scanner features in:

  • Easy to scan large or small things even a coin
  • Resolution of 0.020 mm
  • Rapidly switch two scanning modes
  • Scan deep hole by single red laser line
  • Insensitive to environment

Case Analysis

1. High-precision 3D scanning and obtain 3D data

2. Import 3D data and intercept the bottom outline of the impeller

3. Draw the bottom outline

4. Create CAD model by rotating

5. Segment blade & surface fitting

6. Cut the blade’s outline by rotary projection

7. Draw the blade outline

8. Create a single blade CAD model

9. Create complete blade CAD model by circular rotation

10. Get a complete 3D model

The PRINCE 3D scanner fast captures 3D data such as deep holes and inaccessible potions of the complex object. With the help of 3D scanning technology, manufacturers accelerate R&D flows and get product quality improved.
