UltiMaker S8 Installation and user manual
4.5 Printing process
This section describes the various steps taken by the printer and/or the operator during all stages of
the printing process.
Pre-print
When a print job is selected, either remotely or via USB, the UltiMaker S8 will automatically prepare for printing. This
can take several minutes and includes the following processes:
• Configuration check. The printer will check if the printer has the right configuration for the selected print
job (print cores and materials). If so, the print preparation will proceed. If not, the printer will show a
configuration change request.
• Preheating. The print cores and build plate will heat up according to the material settings.
• Active leveling. The print cores will probe the build plate in several locations to create a detailed height map.
This information will be used to ensure optimal adhesion of the print.
In combination with a Material Station, all materials are in a pre-loaded state. When a print job is started, the
required materials are automatically forwarded to the print head. The UltiMaker S8 will prime the materials.
Printing
After preparation, the print will start. Normally, no interaction is required during the printing process.
However, the print could be interrupted by a flow sensor trigger. If the printer detects a problem with material flow,
the print will be paused. This can be because the material has run out or is tangled on the spool. You can then load a
new material spool to continue the print.
In combination with a Material Station, the UltiMaker S8 can automatically change to a new spool if the active
material runs out. There must be a second spool of the same material loaded to benefit from this feature. If
there is no other compatible spool available, the print will pause until a new spool is placed in a material bay.
Keep the door closed during printing for safety and optimal air management. Never reach into the UltiMaker S8 while
the printer is in operation.
Note: If something goes wrong during printing, pause or abort the print job via the display or Digital Factory.
Post-print
When the print is done, the printer will cool down and lower the build plate. It is recommended to keep the door
closed until the cooldown process has finished for optimal air filtering.
Hot surface warning: Always wait until the build plate has cooled down to a safe temperature (the display will
indicate a hot build plate with an orange warning bar).
Open the door and take the build plate out of the printer to remove the print. Once the build plate has been cleared
and placed back in the printer, select Confirm removal on the display. This will allow the next print job to start.
