Hi list,
Does anyone here have an idea of the thermal conductivity of the RapidSteel
(whichever evolution...) but before SLS (in the powder bed) ?
Thanks a lot.

Franck,
The thermal conductivity values reported for RapidSteel 2.0 are correct.
The primary difference between RapidSteel 1.0 and 2.0 is the thermal
conductivity of the infiltrant. The thermal conductivity of copper is
401 W/mK and the thermal conductivity of Bronze (89% Cu, 11% Sn) is 54
W/mK. The thermal conductivity of 316 stainless is 13.4 W/mK. If you
have a combination of the two metals, the thermal conductivity can not be
greater than the individual components. If the RapidSteel 2.0 sample was
fully dense (without defects), the thermal conductivity would approach 31
W/mK.
(55%)*(13.4 W/mK) + (45%)*(54 W/mK) = 31.5 W/mK
This number is in good agreement with the value reported.

I have got a copy of RapidSteel 2.0 properties.
The given values for the thermal conductivity are 23 W/m
