Outsource 3D Reverse Engineering Services
Before talking about the 3D scanning and reverse engineering service, it’s a good idea to make a small introduction about what reverse engineering is. Reverse engineering is the process that allows you to convert all real objects into a digital file , through software, obtaining the exact mathematical measurements.
With this operation, the piece is digitized first, i.e the physical quantity is converted into a digital 3D model, and then the surfaces of the object are mathematically reconstructed to duplicate, modify or analyze it. According to traditional methods, the acquisition of the geometry of the object is achieved with a manual measurement, while we will see how this process can speed up and make more accurate through 3D scanning for reverse engineering.
The 3D scanning for reverse engineering makes it possible to accurately acquire 3D shape of the object, in a fourth of the time compared to manual methods. Thus obtained the form, through appropriate tools and software for 3D scanning and reverse engineering, you can then proceed with reworking this data in surfaces or solid mathematics.
The measurement that is performed by 3D scanning uses a 3D digitizing technique that accurately captures and recreates the shapes of the object. For the detection you can use 3D contact scanners, or touch probes, or non-contacting optical 3D scanners, faster and easier to handle, laser light or structured light.
In more detail, the file acquired by the 3D scanner is in the form of a “point cloud” and, following a triangulation process that creates polygons, is transformed into a polygon mesh. This process can take place in real time.
The mesh will then be reworked through a software in mathematical surfaces, better known as NURBS, or solid entities, to obtain the starting point for the design of the object to be modified or reproduced exactly.
The reconstruction process is useful for analyzing the piece you are working, but more often the reverse engineering is required to take the measures and the forms as a starting point to draw another object.
Any prototype or model, even created manually, can subsequently be produced by machine, once the executive machining tables or 3D models have been reconstructed on which to calculate the tool paths.
All the reverse engineering process as described allows to recreate the CAD model, the executive tables and the base for any subsequent processing.
3D scanning reverse engineering: what are the application areas?
3D scanning and reverse engineering can be applied to the most diverse sectors , from industry, to manufacturing or crafts, and allow to recreate the CAD mathematics of objects, spare parts, worn molds, artefacts, shoe forms, parts of car, or any object that does not have the original designs.
Here are some of the 3D scanning and reverse engineering applications:
-Of ‘Sector automotive , to digitize auto parts such as frames, hoods, doors, bumpers, reservoirs, engine parts, windshields, and quickly make changes to create new design;
-Sector of ‘ industry : to get the designs and 3D models of objects you want to quickly make changes such as casings, impellers, turbines;
-Manufacturing sector: it is possible to recreate the original 3D drawings and models of old and worn molds ;
-Sector of art or craftsmanship : you can produce endless copies of an object created artistically and manually as statues, unique creations, vases, artifacts, jewelry;
-Interior design : for example to recreate design objects and furniture, handles, chairs, wardrobes, legs of worked tables and friezes.
These listed are just some of the possible areas of application where reverse modeling is required starting from the data acquired with a 3D scanner.

Is reverse engineering possible using a 3D scanner?
-The process of reconstruction of CAD mathematics is faster if you use a 3D scanner to detect the characteristics of the object. This tool allows to acquire the real shape, in a 3D mesh that is then transformed into NURBS or solid surfaces through a reconstruction process with appropriate software.
-With this operation you get CAD mathematics and you can reproduce exactly the object as it is, or you can model it in 3D and make a different shape.
-Naturally, using a 3D scanner, the process becomes faster than in the case of manual, 2D or point-to-point measurements, and allows cutting the times that would have been necessary to completely create the object without having any initial trace.
-3D scanners that allow you to digitize objects can be of different types, for example they can be 3D contact scanners – also called CMM probes, or you can use optical 3D scanners not in contact with laser light technology or structured light , which are generally more manageable and allow to make detections by moving easily around the object, without constraints.
CAD reverse engineering software
-The CAD file obtained by reverse engineering, you can completely model, redesign or use to create new projects, based on the form that was created or acquired through the use of a 3D scanner.
-The advantage of working a CAD from reverse engineering is time saving: you can finish a project faster and you can develop more components in less time, increasing productivity.
-Some software also allow you to work, in the same graphical interface, both the 3D scanning file that was acquired by a tool to detect the 3D shape, which then perform the mathematical reconstruction of the CAD file.
-These software can also be referred to as “mesh to CAD reverse engineering software” and have integrated functionality for both importing and modifying 3D scanning data and then creating complex surfaces and geometries.
-Depending on your needs we can deliver the file in mesh format, such as STL from 3D scanning, or in solid format, IGES or STEP, but also in the native CAD format of the software you use.
