3D digitization for reverse engineering.

3D digitization for reverse engineering.

With reverse engineering, like its name says, the usual and natural process is invested to reach the manufacture of a product.

Do you want to update the design of an old object that you think can be improved?

Once an object, a piece or any component of a mechanism has been scanned in 3D (digitized), we can use the polygonal mesh (composed by polygons), resulting from the scan for different purposes.
With the properly textured 3D model we can create renders or representations of still image or video, … or, in addition to well textured and properly optimized for quick download, create an interactive presentation, to publish on a web page or share online.
It is also possible to obtain a polygonal mesh with resolutions as high as necessary to reproduce it with maximum fidelity through 3D printing.

For reverse engineering we have to remodel the polygonal mesh, converting it into a mesh of parametric curves.

This makes possible to study it, add modifications based on the data obtained, and obtain as a result a product suitable for its manufacture.
During the remodeling process of the new object, different prototypes can be created using 3D printing to be able to verify the modifications made up to that point and introduce the necessary arrangements into the design.

The digitization process of a scanned object or mechanism for reverse engineering is based on converting the data obtained as a virtual object from a 3D scanner into CAD (computer-aided design) format by the detailed analysis of its manufacture, its operation, what are its aerodynamic, hydrodynamic qualities, resistance to specific efforts, etc. This procedure facilitates the study and rectification of an object or the creation of a new object without copying the original.

The 3D scanning software, working with the scanners, provides us with a “point cloud” of the object that determines its precise shape and exact dimensions. Once this data is obtained, we can create a CAD file, parameterizing the 3D mesh resulting from the scan, for its treatment with the appropriate engineering software, to represent the virtual object in a computer simulation.

Reverse engineering is often used because the technical documentation for a particular object or device has been lost or has never been written down.
It is used by some companies to examine competing products, to analyze for example how it works, what it does, what components it consists of and how they are related to each other, estimate costs, identify potential patent infringements, etc.
This technique is applicable to many other fields of engineering and design such as the manufacture of automotive seats and accessories, systems and environments for human use (ergonomics), quality control, prototyping, hydrodynamics of ships, airplane and automotive aerodynamics, etc.
