REVERSE ENGINEERING:
Introduction – traditional relief
Example of output
Traditional relief
Method that uses meter, gauge, levels, lines, laser rangefinder and other tools
for the direct measurement of distances and angles.

REVERSE ENGINEERING:
3D Scanning Relief with 3D scanner
Method that employs structured light that
represents the surfaces of the object in three-
dimensional space

Reproduction in scale of existent
objects
SCANNING OF EXISTING
OBJECT STL RAPID
PROTOTYPING (Stereolitography,
sintering, object, FDM)
![Page 14: 3D scanning and Reverse Engineering](https://reader033.fdocuments.us/reader033/viewer/2022042615/55aa01ab1a28ab15188b45dd/html5/thumbnails/14.jpg)
Dimensional control, verifications of
variances.
Ability to associate the scan in Rapid Fit
Verifications of symmetry and surface
trends.
Verifications of discrepancies between
CAD and a real object (ex prototype),
between objects of the same series or
different batches (ex. Production of the
same object with different technologies),
including mold and real object.

Verifications deviations between CAD and real object

Structure for fixing the
components in their conditions of
use for the analysis of quality.

SCANNING THE EXISTING OBJECT
STL REVERSE various
- Relief for rebuilding damaged items (ex,
mold damaged)
- Relief for reconstruction of mathematical
objects non-existing (ex, the object on
which you want to start a new production
or storage.
- Relief for assembling parts or packaging
design

There are different approaches and
ways of working to “mathematize”
mesh, these changes according to the
purpose of the work and the
charasteristics of the object.

Photogrammetric Relief
Method that employs metrical rooms
or calibrated for the indirect
measurement of points in space.
