Example 11: Clay Model
Click on image to enlarge
Problem: To reverse engineer a clay model of a computer speaker for the purpose of
rapid prototype production. Due to the delicate nature of this prototype model, the piece needed to be
measured using a method that would not distort / damage the sculpted part surface.
Process: The creation of the required data called for a very dense ‘point cloud’ of
data. The process used on this piece involved the use of a 3-Dimensional laser digitizing system. Nearly
1,000,000 individual data points were originally measured from the piece, which was then significantly
reduced to around 250,000 points for the creation of the rapid prototyping data file
(.STL format).
Solution: The measured ‘point cloud’ was imported into one of our advanced CAD
software packages for processing. Each point was connected to its neighboring points in the form of
triangles. These triangles collectively create the required mesh which rapid prototyping machines need
for model creation.
