Cleaning The Machine And Changing The Powder; General Legal Information - SINTERIT Lisa Pro User Manual

D. Cleaning the machine and changing the powder
1) Material with higher melting point (H) -> Material with lower melting point (L)
When changing from ​ H to ​ L ​ , no dutiful cleaning of the inside of the printer is required.
The same actions as cleaning the machine after printing should be carried out.
2) Material with lower melting point (L) -> Material with higher melting point (H)
● When changing ​ L to ​ H it is required to clean the machine very precisely. Special
attention should be paid on the bottom and side walls of the print and FEED BED's as
well as the RECOATER's guide bar. It is also recommended to clean the area around
the BEDs using compressed air. Disassemble the RECOATER's casing and remove
the remaining powder. It is important to clean the printer as thoroughly as possible
before adding ​ H ​ ; otherwise, the remaining ​ L ​ ( e.g. FLEXA with its properties similar to
rubber, becoming liquid in temperatures above 100[°C]) may get into the mechanism
responsible for moving the BEDs or the RECOATER's mechanism, and damage the
machine.
● Clean the LASER PROTECTION GLASS as some fumes may release during printing
with FLEXA and make the glass foggy. If it is hard to clean the surface, you can use
ethyl acetate.
WARNING!
Important messages will be displayed in Sinterit STUDIO 2019, not abiding
with which may result in damaging the print and/or the printer. Similar
messages will appear on the display of Sinterit LISA PRO Printer. Please
read them carefully in case of changing the powder from the ones with
lower melting point to those with higher melting point (especially FLEXA or
TPE to PA12 or PA11).
The thorough cleaning procedure must be performed if you switch from any material
with higher melting point to a material that melts at lower temperature.
