Five Best Practices for First Article Inspection with a 3D Scanner

3D scanning can be an effective tool for first article inspection. It is relatively fast, produces accurate results, and can be more cost-effective than other solutions. However, 3D scanning does not work for every first article inspection application. For example, if the part includes internal features or surface finishes that are not compatible with optical inspection tools, a different approach might make more sense.

10 Commonly Missed First Article Inspection Issues

First article inspection is an important component of successful manufacturing. The first article in production must be inspected, or measured, to determine whether it meets the engineering specifications. If it does not, corrective steps must be taken. These steps take time and money, which is why first article inspection must be quick and accurate.

Pros and Cons of Color Mapping for First Article Inspection

Color mapping is commonly used as a profile analysis tool in first article inspection primarily because it allows you to quickly visualize the differences between the scanned part and its nominal CAD model specifications. After an object is scanned, point cloud software highlights the differences using a color map. Each color represents a different degree of variation between the scanned part and the original design so that manufacturers are better able to understand what the part’s actual condition is and refine and improve the corresponding manufacturing processes.

Why Are We Still Bluing and Scribing Castings?

Bluing and scribing of castings (also known as casting layout) is a tried-and-true method for dimensional inspection of a metal part made typically by sand casting or permanent mold. By placing the dimensions from a drawing on to the actual part, you can determine whether it meets the specifications. Although this method has been used for decades, new technologies have effectively superseded the need for it in most cases.
