A 3D scanner is a device that
analyzes a real-world object or environment to collect data on its shape and
possibly its appearance (i.e. color). The collected data can then be used to
construct digital, three dimensional models.
·
Creation of points cloud system representing a
geometric surface with a laser beam.
·
Records distance values to the surface within the
scanner field of view.
·
The object is then recreated in a “reconstruction”
software package.
Collected 3D data is useful for
a wide variety of applications. These devices are used extensively by the
entertainment industry in the production of movies and video games. Other
common applications of this technology include industrial design, orthotics and
prosthetics, reverse engineering and prototyping, quality control/inspection
and documentation of cultural artifacts.

3D Laser digitizing systems are
utilized in the areas of analysis, design and verification, rapid prototyping,
tooling/part development, metrology/Q.C and updating existing CAD which
includes manufacturing automotive & aerospace parts, recreational and
consumer goods and medical devices, as well as the entertainment, museum and
power generation industry.
Laser scanning describes the general method to sample or scan a
surface using laser technology. Several areas of application exist that mainly
differ in the power of the lasers that are used, and in the results of the
scanning process. Low laser power is used when the scanned surface doesn't have
to be influenced, e.g. when it only has to be digitized. Confocal or 3D laser scanning
are methods to get information about the scanned surface. Another low-power
application is structured light projection systems that are used for solar cell
flatness metrology enabling stress calculation with throughput in excess of
2000 wafers per hour.
For high laser power, the
influence on a working piece depends on the power of the laser: medium power
values are used for laser engraving, where material is partially removed by the
laser. With higher powers the material becomes fluid and laser welding can be
realized, or if the power is high enough to remove the material completely,
then laser cutting can be performed.
Benefits
of 3D Scanner
·
Faster data collection
·
Save time modeling complex components
·
Shorter Project Cycle Times
·
Data can be integrated with CAD
·
Accurate representation of surfaces impossible to
achieve with current solid modeling technology (Wood grains, bumpy surfaces,
curves, grooves, etc.
·
Allows for better analysis in CAE Platforms.(Motion
simulation, fluid flow analysis, FEA analysis, etc)
Drawbacks
of 3D Scanner
·
High resolution scans mean large files.
·
Usually post processing required
·
Requires high end technology
