More and more popular innovative technology of 3D print finds its application in many stages of preparing the final version of a product. Using spatial scanning, you can e.g. get data necessary to complete standard documentation and enrich it with a visualisation of physical details. What are the features and the most important benefits of using reverse engineering?

Reverse engineering – what is it?

Reverse engineering is mainly an analysis of a factual product that gets transferred to the virtual reality through getting a file in 2D or 3D format. Due to gathering information concerning geometrical features of a product, 3D model is generated that includes physical properties of the product. Digitalization and the final form of a virtual prototype are made by using specialized tools, such as 3D scanners, laser scanners and coordinate-measuring machines. Reverse engineering allows to reproduce constructions of already existing objects, determine the content of their components or recreate lost documentation. The broad use of this kind of engineering makes it easy to apply in motor, shipbuilding, medical industry or aviation.

Models in reverse engineering

Reverse engineering can be used in practice in a few ways. Among available models, there are 3 most used:

  • Areal model – it allows to precisely copy a particular object, determining its surface and detailed parameters. When applying this type of method, it is possible to analyze product in a fast way to detect any defects, working marks or other structure imperfections.
  • Parametric model – enables mathematical definition of a product, thanks to which, CAD models are created. During using parametric model, defects of a product are ignored, whereas attention is drawn to getting data necessary to editing a prototype, its modification or completing 2D documentation.
  • Hybrid model – is an integration of the above-mentioned models – areal and parametric. As a result, there is a chance of creating a prototype, modifying it and preparing documentation

The benefits of using reverse engineering

Using reverse engineering entails a string of innovative solutions that make work easier. Generating 3D models of the products contributes to obtaining complete technical descriptions, that have an influence on preparing a comprehensive description of the product. Additionally, conducted analyzes provide an opportunity to design forms and matrices adjusted to existing components, introducing changes inside the product structure, as well as testing the endurance of particular elements, thanks to the different work conditions of a certain device.

Reverse engineering is a fast and tested method of scanning objects, and subsequently, of changing a structure of products. It allows to create proper parts and practical tools, necessary to execute all planned modifications. Techniques and models of reverse engineering are the way of receiving CAD data, useful during conducting tests or completing documentation.
