SLS Part/Feed Bed temps?

From: Brian Caulfield (

I am just curious about a few aspects of the SLS process as regards temperatures.

What is the ideal Part bed temperature?

For PA we have the part bed 12 degrees C below the Tm (Approx PB temp of 150-153), can anybody tell me why 12 degrees?

What is the ideal Feed bed temperatures?

Should the part bed temperature be proportional to the energy density from the laser i.e decrease as the ED increases?

If anybody has an ideas on this topic or knows a bit more than me on it I would love to hear it.
