In the context of engineering reverse engineering means the creation of a digital 3D model based on physical master.
When reverse engineering? It Is used mainly for the renovation of spare parts and models, which we do not have access to technical documentation Or 3d model and we decided to produce them again.
Why do we need to produce a 3d model? If the works are produced By 3d printing (additive technologies), we will need a 3d model for production.
In the manufacture of spare parts , 3d printing is mostly the cheapest method of production, given that we do not need any other production tools and preparations.
If the model will be produced by a technology other than 3D printing, it will serve as a source of form references for the creation of the drawing technical documentation (using parametric modelling software).
Reverse engineering reveals how the works were originally produced and usually the assembly needs to be completely dismantled. Part of the parts gradually create 3D models.
Several reverse engineering procedures can be applied in practice:
1. Manual measurement,
2. Semi-automatic measuring of the touch probe,
3. Scan the surface of the laser,
4. Optical 3D scan of the surface,
5. CT Scan.
In the table below we compare the speed, accuracy, price and use of each measurement method:
| Method of measurement | Speed | Accuracy | Price | Use |
| Manual measurement | Slow | Low | Low | Simple bodies with a low number of details and perpendicular surfaces |
| Measuring the touch probe | Slow | High | High | Precision engineering Parts |
| Laser surface Scan | Fast | Average | Average | Complex shapes with a higher number of details and non-symmetry |
| Optical scan of 3D surface | Average | High | High | Larger shape-complex bodies with a high number of details |
| CT Scan | Fast | High | Very high | Parts where volume reconstruction is required, including cavities |
We also offer comprehensive reverse engineering in our services. Just when you contact us about what model you are interested in and we will advise you on the most appropriate option that we can also implement.
Whether we decide for any procedure, the great advantage of reverse engineering is that when we already have a replica of The physical body in the 3d model, we can further adjust it so that it is for example. more solid, chemically or mechanically resistant, whether or not by changing the shape or material.
