Abstract
Additive manufacturing is a cost effective way
to generate copies of damaged parts for
demonstrations. Integrating scanned data of
a damaged area into an existing model may
be challenging. However, using the relatively
inexpensive Nettfab software (from one can
generate a “watertight” model that is easy to
print.

Step 1: Scan Data of Damage
• Example of Scanned Data saved in a STL
(Standard Tessellation Language) Format

Step 2: Import Data into Nettfab
and Make Repairs
Imported data is cleaned up and holes
filled in so that the damaged area is now
one solid model or “watertight”.

Step 3: Combine the “Repaired”
Scan with the Desired Model
Model
Scanned Data
Nettfab’s Boolean function subtracts the
scanned damage from the target part

Step 4: Generate a New STL File
Export a new stl model file of the damaged part
Nettfab also
allows one
to add text

Step 5: Print the Part
Example Prints from a Stratasys Fortus 400mc
Slice height of .005” Model Material - ASA
