3D scanning and reverse engineering
3D scanning and reverse engineering
The structured-light optical 3D scanner allows to acquire with great precision the tridimensional shape of an object and make complex shape 3D models difficult to achieve by cad design only. It’s an indispensable tool for the solution of reverse engineering problems, artefacts design or spare parts in absence of original digital model.
The acquisition and digital modeling process is generically followed by a data elaboration phase that has the purpose to make the models really usable by various applications, or in synergy with a tool machine or a 3D printer.
The 3D scanning is performed without need of contact with object surface, so its applicability is very wide and include many sectors including:
Industrial design
Thanks to optical 3D scanning it’s possible to gain any analytic or structured shape to better define the design of a product starting from a phisical object, for example a prototipe.
The digitalization of a prototipe or any phisical model helps the designer to develop his own ideas in a direct and prompt way and more creative.
Mechanical and automotive
The optical 3D scanner allows to test mechanical parts verifying the correct coupling before their production.
It’s also possible to digitalize bigger dimension parts as hoods, bumpers, doors, motorcycle frames, rims, fuel tanks, silhouettes of laminated glass for windshields, etc.
Moulds and moulding
The optical 3D scanner is ideal for the creation or reconstruction of mould for artistic and mechanical objects necessary for their production.
It’s a very valid tool for the recostruction of worn moulds, in fact allows to make a 3D model faithful of the existing mould shape where it will be possible to eliminate defects of wearing and aging by reconstructing original designed 3D model.

Dimensional inspections
The optical 3D scanning technology intervenes so important in the field of dimensional testing.
Very accurate 3D measurements coming from model acquiring allow to tackle activities of dimensional inspections and quality control.
Geomagic Qualify software make the comparing from 3d scanning data and nominal CAD mathematic; it’s possible to draw up detailed reports that underline gap, out of tolerance areas and surface to surface deviations.
Fashion, shoes and accessories
With the aid of optical 3D scanning system it’s possible to obtain a perfect digital copy of the physical part subjected to the scanning.
Buckles, buttons, clips, rings, jewelry, engravings, silver frames, small metal, precious objects are all details that, through non-contact optical 3D scanning, can be acquired, catalogued and used to start the design of new variants and stilistic alternatives.
The optical 3D scanner is an optimal solution for the digitalization of silhouettes of soles, heels, wedges, shapes.
The digital copy of a real model helps the manufacturer to creation of new stilistic models and mould making.
It also can be used for the take-over of logos, engravings, embossing, toe.
3D archiviation
The acquisition of the geometry of an object by optical scanning 3D is a fast and non-destructive method to create a digital archive of products, goods and collections, offering many opportunities such as: reproduction, reconstruction, restoration, development of new product lines, catalogs 3D virtual animations, etc…
Artistic and restoration
The acquiring and view of tridimensional models of real objects represents an important resource and potentiality.
The field of application of Artistic and Restoration is one of the most interesting, in fact the optical 3D scanner is proposed as a valid solution for copy of complex sculptured shapes rich in details as friezes, bas-reliefs, busts, statuettes with the purpose to make an archive or a digital catalogue and/or reproduce with rapid-prototyping technology or to make a complete digital restoration.
It’s a valid technology applicable in all artistic sectors: ancient and modern art, holy art, funerary art, sculpture, pottery, glass art, musical instruments, silverware, chandeliers, furnishing.
It’s possible to make copies of pieces to reproduce or restore identical to the original, or it’s possible to make enlargements and reductions for commercial or expositive purposes.
Collecting and modellism
The optical 3D scanning technology is very useful to acquire handcrafted models and to acquire existing objects to reproduce in scale.
Coins, statuettes, plastic toys and small metal will can be copied faithfully returning STL files usable for rapid prototyping.
