3D scanners are widely utilized in various branches of industry, architecture, art, medicine, and are taken advantage of to improve production processes, especially those strictly connected with 3D modeling and designing. Our comprehensive offer includes such devices as well. Among them, there are units that may serve various purposes, depending on their technical parameters. Additionally, we are knowledgeable and experienced when it comes to practical applications of 3D scanners, as we have realized numerous projects for companies operating in a myriad of branches of industry – check our references. Exemplary fields, in the case of which the use of 3D technology may be of use are:
- Quality control based on the comparison of the created model with the CAD model by means of examining surface deviations,
- Reverse engineering that it the preparation of a CAD model basing on a 3D scan of an object,
- Reconstruction of damaged items in the case of lacking technical documentation,
- Quick item copying thanks to the use of the „FROM MODEL TO MODEL” process,
- Creating three-dimensional graphical model of unique items (for example: sculptures, architectural elements),
- Collision analysis in the case of digital part adjustment,
- Quick item dimensions adjustment,
- Making item documentation and its digital copy (2D/3D), measurement-related reports.
Branches of industry the representatives of which we have been collaborating with and which have been taking advantage of 3D scanners as operational tools are:
- medicine (orthopedics, prosthetics, plastic surgery, orthodontics, etc.),
- architecture (building location and design archiving, mock-up creation, etc.),
- museology (museum object digitization, landmarked building archiving, virtual museums, etc.),
- industry (reverse engineering, quality control, quick prototyping, etc.),
- multimedia (factual figure virtualization, advertising, special effects, etc.).
A short description of a 3D scanner operational paradigm and an exemplary image presenting the said process can both be found below:
Three basic components that affect the specificity of a 3D scanner are: light source high resolution digital camera(s) and scanner’s software. The creation of a digital 3D model by means of white light scanner is performed in the following manner:
- Desired item is illuminated by a source of light being a high resolution digital projector. Light beams of various structure are utilized for the said purpose (black-and- white stripes reflecting on the model in the film).
- Digital cameras capture reflected light together with cues on how images with straight lines reflected on the scanned item are bent on the surface of the item.
- Specified pieces of information are then sent to the software, which, basing on them, creates a set of points in a three-dimensional coordinate system, which is the equivalent of replicating the item in a digital form.
- After a single scan is completed, several more are needed to obtain a factual shape and form of the object.
- Then, the 3D scanner is no longer needed. The prepared 3D model can be processed further depending on the desired application of the scan made.
- Depending on the software used, the outcome of 3D scanning is typically a file in a format allowing for printing the model by means of a 3D printer (STL) or in a format making it possible to safely store 3D models (OBJ, PLY)
In the movie clips below, the process of object scanning by means of Artec Eva and LMI Advance is presented.
The quality and duration of scanning depend on, among others, type of utilized light source, scanner resolution, and the number of scanner cameras. Nevertheless, even a state-of- the-art scanner may be useless if its user does not have basic knowledge on 3D scanner operation (for example, in terms of its calibration, configuration, and principles of preparing the environment and the object for scanning).
