Franck,
The information I have from DTM is as follows:
Coefficient Thermal Expansion x 10-6 -60 to 450 deg. F (-51 to 232 deg. C) using ASTM E831 in / in/deg F (m/m/deg C) is 7.99 (14.4)
The information I have is a year old or so. DTM might have more current data.
Hope this helps.

Subject: Rapid Tool / coefficient of thermal expansion
What is the coefficient of thermal expansion (%) of a mould or part built
using the Rapid Tool metal process from DTM?
Is it only related to the percentage of copper and steel?
