We can define 3D scanning as the process that includes scanner technology to apply reverse engineering and scan the object, parts, or area in question.

Making a 3D scan with a laser scanner and then digitizing the physical objects created from the capture will allow data content that, processed with software, can deliver a product with more detailed information about the model or scanned construction.

This type of service, in conjunction with scanning solutions, can add value in resolving decisions in a company. The models obtained from space can provide data such as adjustments or deformations obtained from the place through reverse engineering. A 3D scanner allows a generation of a digitized model suitable for industry or other sectors.

Scanning technology

The use of laser light is one of the means that allows for capturing free-form shapes, and any real-world object, with 3d scanning and the correct use of structured light scanning on the scanned object, guarantees fine details and precision.

Some methods, like laser triangulation scanners, can offer highly accurate point clouds from scan objects and areas. In conjunction with data processing and CAD software, point cloud data can provide relevant data for your company and decision-making.

CAD software to scan objects

The scanning process can be complicated if you do not have various software packages to generate a cad model and thus obtain a digital representation. Using software complemented with laser scanning technology is an excellent solution to get different points of a three-dimensional picture.

Essential factors in a 3D scan

The area or place

The precision and fidelity of digitization will depend on the sectors to be scanned. Also, privacy will be a crucial factor in the speed to generate it and thus avoid interruptions so that the scanning processes fulfil their function correctly.

Lighting conditions

Light conditions will also be essential, as a well-lit environment will make scanning more accessible and give you more accurate models. The capture of textures is more delicate, so the object to be scanned mustn't have reflections or other things that could interfere with the process.

Dimensions of the object or place

The object's size to be scanned will also play a valuable role since a high number of polygons can make it difficult to process the model, and a lower number of polygons can lead to poorly defined textures.

Software used

The software used is also one of the factors to consider since it must be able to process the data captured by the scanner efficiently and give a good result. For example, CAD software or other platforms that are on the market will be of great help to generate quality digitization.

Advantages of a 3D scan

  • The advantages of using this technology are mainly:
  • A three-dimensional representation of an object, piece, or space can be made without the need to be physically present.
  • It is possible to obtain a replica in digital format of the scanned item.
  • It facilitates the work of those who have to create models from scratch.
  • It is a handy tool for conserving historical goods since it allows making a three-dimensional copy without intervening directly on the original.
  • It can be used to produce virtual reality or augmented reality experiences.

Applications of 3D digitization in parts and spaces

The use of digitization is not exclusive to objects for 3D printing because it can also be used to obtain models of parts or spaces for other benefits such as:

  • Reverse engineering: it is possible to execute a three-dimensional copy of an object to study and learn how it works or improve its design.
  • Architecture: the digitization of buildings or interiors allows, for example, the creation of a virtual visit to a space.
  • Cultural heritage: allows three-dimensional models of historical assets to be obtained for their conservation or study.
  • Medicine: allows three-dimensional models of organs or body parts to be obtained for training or study.

As we can see, there are many possibilities that three-dimensional digitization can offer, both in the field of objects and in that of spaces. If you need more information on this subject or are looking for a company specializing in this service, do not hesitate to contact JT Reality Capture.
