Has anyone faced the problem of having powders sticking on their SLS rollers as they goes over the part bed. I am testing out on some biomaterials and it seemed that the powders tend to stick on the rollers despite the fact that the I have ensured that part bed temperature is raised to an appropriate temperature. The powder size is around 25 micron so I do not know if this is due to electrostatic. I do understand that the average powder size of Duraform is about 60 micron.
Anyone out there with any advice and experience to share. Thanks in advance.
