dear friends

I am a post graduate student doing research in Selective Laser sintering Polymer powders at PSG College of Technology

Machine : Sinterstation 2500 plus

material : Duraform PA (polyamide)

In my experiments I infer that accuracy of exposed powder is better that that of fresh powder with 11W laser power

what may be the reason behind it?

Before this experimentation we assumed that fresh powder may give better dimensional accuracy and using only fresh powder for industrial projects.
