3D printing

An institution I am working with would like to have a three-
dimensional wax object 3D scanned and 3D printed. This composite
object consists also of 18th century silk, linen, and met threads.
Due to the construction of the object, it is not possible to shield
the silk from the light exposure from this process during the 3D
scanning.

The proposed protocol for the 3D scanning would consist of the use
of structured light scanning with a 200 lumen projector with an
R/G/B LED light source. The cumulative amount of light exposure
would range from a minimum of 2,000 lumens (40 scans x 15 seconds
each) to a maximum of 16,000 lumens (80 scans x 60 seconds each).

The institution's objective is to display the reproduction and to
put the original object in permanent storage. Does anyone have
experience with or recommendations for using 3D scanning techniques
to capture historic textiles?   Does anyone have experience with or
recommendations for using 3D printing in ABS to replicate beeswax? I
am interested in providing the institution with information
regarding the benefits and drawbacks of utilizing this technology.
