Get to know 3D scanning technology

Without a doubt, technologies are really cutting-edge and incredible because they succeed in converting ideas into a reality, including 3D scanning. Who can reap benefits from this technology? Anybody in testing, surveying, design, manufacturing, and so on. Below, we will provide you with what you should know about this technology.

What is 3D Scanning?

3D Scanning refers to a non-destructive and non-contact innovation with the capability of capturing physical object shapes digitally utilizing a laser light line. 3D scanners make “point clouds” of information from an object’s surface. That means this scanning technology is a method of capturing the actual shape and size of a physical object into the computer realm as a digital three-dimensional display.

3D Scanning Benefits

  • Capture any physical object’s entire physical measurement fast
  • Speed up your design work
  • Make sure that parts will match each other on the first attempt
  • Leverage advanced manufacturing on components that were initially produced before CAD (Computer-Aided Design)
  • Make a comparison between produced components’ “as-built” status and “as-designed” product unit

3D Scanning Process

Acquisition of data

Put a physical object that needs laser scanning on the digitizer bed. Then, exclusively developed software is in charge of driving the laser probe over the subject surface. This probe does the job of projecting a laser light line onto the surface, whereas two camera sensors keep recording the distance and form of the laser line in 3 dimensions when it passes along the physical object.

Data that result

The physical object’s shape shows up as countless points referred to as a “point cloud” on the monitor of the output device when the laser travels capturing all of the object’s external form. The process is really rapid, collecting more than 700k points each second as well as really accurate.

Modeling option based on application

Following the creation of the massive point cloud data files, you have these registered and combined into a single 3-dimensional display of your physical object, then processed with a range of software packages appropriate for a particular application.

Inspection based on point cloud data

In case you utilize the data for inspection, you will want to compare the scanned physical object to the CAD data of the design team. The outcome of the comparison procedure is present in a color-coded deviation map formatted in PDF that demonstrates how the CAD and scan data are different. 

Reverse engineering based on CAD Model

3D scanning is the most precise, rapid, and automatic method of obtaining 3D data to serve in reverse engineering. Utilizing exclusively developed software, the point cloud data is useful for building a 3-dimensional CAD model of the component’s geometry. The 3-dimensional CAD model helps with the accurate remanufacturing of the scanned physical object. 3D Laser Scanning Design can offer surface models or solid ones with higher sophistication, whichever requirements are set down for the application.
