Powder Refreshment; Powder Refreshment With The Phs/Multi Phs - SINTERIT LISA X Original User Manual

12. POWDER REFRESHMENT

Powder refreshment is a process that restores the initial properties of the powder that is recovered from the printing.
IMPORTANT!
• Every SLS powder recovered in the printing process requires sifting.
• Not every SLS powder recovered in the printing process requires adding fresh powder.
• For detailed information please refer to the specifications of the specific SLS powder. You can
find them on our website www.sinterit.com.
IMPORTANT!
Information about how much fresh powder needs to be added in the refresh process will be
displayed on the printer screen after the printer cleaning step and also generated in a report from
Sinterit Studio.
ATTENTION!
Always wear appropriate personal protective equipment when working with powder: clothing,
protective glasses, facemask, and gloves. You will find a suitable kit in the Dedicated Powder Tools
package.
