We've run into similar issues in the past - several ways to solve it. Best way is to replace the piston seal. We've also noticed that the addition of too much flow additive can cause issues with seals that are considered good.

Subject: [rp-ml] Sinterstation 2500+ Part Piston Leak
Howdy,
I have a powder/nitrogen leak occurring between the part piston and the piston wall on a Sinterstation 2500+ machine while running. After about 1-1.5" of material the gap fills enough that there is no visible drainage. So far it has not affected any parts since it is off in the front right corner (facing the machine) but I would like to resolve the issue. Has anyone else experienced this? Any suggestions for troubleshooting?
Thank you,
Gregory M. Paulsen
