3D Scanning: Inspection and Reverse Engineering

What is 3D Scanning and How Does it Work?

A 3D scanner is a device used to capture the physical shape and dimensions of objects or environments in a digital format. It allows for the creation of accurate three-dimensional representations, commonly referred to as point clouds or meshes. Laser scanning involves the use of laser beams to measure the distance between the scanner and the object's surface. The scanner emits laser light and measures the time it takes for the light to bounce back. By scanning the laser across the object's surface and capturing the reflected light, the scanner creates a point cloud representing the object's shape. Scanners are becoming increasingly accurate and are currently accurate down to the 0.001”!

What Can be Scanned? Are there Limitations?

Scanning is almost limitless, some main uses are to reverse engineer, extract dimensions of mating parts or inspection. Additionally, 3D scanning can be applied to any industry. The ability to scan a part is quick and can provide instant feedback to the operator.

The main limitations are the size of the part, occluded geometries and moving objects (object must remain still).

What Can I do with a 3D Scan?

One of the remarkable aspects of 3D scanning is the multitude of possibilities it offers. The versatility of 3D scanning allows for exporting scans in a wide range of commonly used 3D part formats, providing users with flexibility and compatibility. With such diverse export options available, the potential applications of 3D scan data become extensive.

Once a scan is exported in a compatible 3D part format, it opens up a world of opportunities. One notable avenue is the seamless integration of the scan data into Computer-Aided Design (CAD) software. Beyond CAD integration, 3D scan data also serves as a foundation for generating comprehensive inspection reports.

Moreover, the power of 3D scanning extends to the realm of additive manufacturing, specifically 3D printing. With the exported scan data at hand, it becomes possible to reproduce a physical replica of the scanned object directly through 3D printing technology.

Processing the 3D Scan using Polyworks

What are the key features of PolyWorks Inspection software?

PolyWorks Inspection software offers a range of key features, including data integration, dimensional analysis, inspection planning, GD&T evaluation, reporting and documentation, automation and efficiency tools, advanced analysis capabilities, and integration with various metrology devices. These features collectively enable users to perform comprehensive and accurate dimensional quality control and inspection tasks.

How does PolyWorks Inspection software facilitate the inspection process?

PolyWorks Inspection software streamlines the inspection process by providing tools for inspection planning, measurement sequencing, tolerance specification, and GD&T evaluation. It allows users to import and integrate 3D scan data from different sources, perform dimensional analysis, compare scan data to CAD models or reference objects, and generate detailed inspection reports. Additionally, the software supports automation features, such as batch processing and scripting, to enhance efficiency and reduce manual effort in repetitive tasks.

In which industries is PolyWorks Inspection software commonly used?

PolyWorks Inspection software finds application in various industries, including automotive, aerospace, manufacturing, engineering, consumer goods, and medical devices.

For example, surface deviation analysis allows users to compare the scanned surface of an object with its nominal CAD model or reference geometry. It provides a visual representation of surface deviations, highlighting areas where the actual scan data deviates from the intended design. Surface deviation analysis aids in identifying areas of concern and assessing the overall quality and conformance of the scanned object.
