Rapid Prototyping & Reverse Engineering
Modern 3D imaging technologies like industrial computer tomography
have reached a level of accuracy allowing the use of their output
data within Rapid Prototyping and Reverse Engineering
applications.

cylinder head (800 MB CT-data with 0.3x0.3x0.5 mm voxel
resolution). Lower images: photographs of the original part

The combination of voxel data generated by modern 3D imaging
technologies, e.g. industrial computer tomography with
modern rapid tooling methods, e.g. selective laser sintering and
sophisticated software technology which lines up all technologies
into a single process chain have become a powerful tool for many
application fields. Volume Graphics provides the software
technology needed for this tasks.
Example: reproduction of a cylinder-head of a historic car
engine.
The cylinder-head of a BMW roadster build in 1937 was reproduced
from CT data. The voxel data was processed by VGStudio MAX 1.0,
e.g. to extract the water-jacket geometry. The geometry was
exported as an STL-file which was further used to rebuild the
water-jacket core by selective laser sintering. The water-jacket
core was used for the aluminum casting process.
