Need to make manufacturing design changes? But you don’t have parts data and documentation? No problem! 3D Scanning technology coupled with 3D modeling lets you generate your parts library and documentation.
Mold Making and 3D Scanning
Companies that work with molds often make tooling changes right on the shop floor. These kinds of work-in-process changes help to reduce production delays and keep products flowing out the door. However, what usually happens is that these hand-finished changes result in a mismatch between the original CAD model and the actual physical mold.
When a mis-match like this occurs, it is necessary to determine where the CAD data differs from the actual part, and then modify the CAD data, and that’s where 3D laser scanning proves invaluable. By scanning the actual part, and comparing the scanned data to the CAD model data, the model can be modified to reflect that changes. This means that the current revision is always the one that is used on the shop floor.
Reverse Engineering and 3D Scanning
Another important application is reverse engineering and inspection of complex parts and assemblies. Sometimes it is necessary to generate a new CAD/CAM model in order to update a manufacturer’s database of components that have changed since the original CAD models were developed.
This often occurs in manufacturing of automobiles and aircraft.
By 3D scanning, a color error map can be generated to identify exactly how the current product differs from the original design intent. New products can then be developed from existing products by modifying the CAD model level rather than starting from scratch.
CAD modeling from laser scan data is typically about eight times faster than the time required for processes that involve manually creating the model from CMM touch probe data. The millions of coordinates from 3D laser scanning define all the subtle freeform and surface transitional shape changes that are difficult or impractical from a time standpoint to measure with touch probe.
The advantages of laser scanning in reverse engineering helps explain why the use of this technology is growing so rapidly manufacturing and molding.
Accuracy is the Secret
Accuracy in scanning and accuracy in modeling guarantee the results.
We’ve produced 3D CAD Model Libraries for many different vendors, in multiple CAD formats.
The models we generate are:
- Rich media assets
- Suitable for publishing on your website and for your customers’ use
- Time and resource savers for your customers — a huge marketing advantage
- Directly downloadable for your designs or your customers’ designs
- Useable in engineering, structure building, BIM and other types of projects for faster prototyping
- Useful for retrofitting, reverse engineering and various types of simulations.
- It’s easier to do simulations and physical calculations.
3D laser scanning offers tremendous time savings and cost benefits for many industries. From parts and molds to structures and crime scenes, laser scanning makes capturing details easier, faster and far more economical and 3D modeling brings the details alive in the virtual world.
