Hi
There were quality issues of spreading powder.
Could one give idea to find them, to prevent and fix them?

Hi myying
it seems to me that this is due to the roller,it looks like mechanical damage to scratches or something sticky
can you show a photo of the roller? is it spinning?

Hi myying,

a bit late response, sorry. These kinds of spreading issues are quite common even on the Projet 660. They are usually due to dirty spreader roller / scraping blade, or more often because of worn out powder (i.e. some of the finer granules have gone after many print works)

cheers
