8 USE OF THE PRINTER
ATTENTION:
The operations related to these activities must be performed by authorized and professionally
qualified personnel.
ATTENTION:
Pay particular attention during the various stages of the procedures, it is essential to wear gauntlets
because there is a risk of burns.
ATTENTION:
During operations, the operator must wear all the necessary Personal Protective Equipment (PPE).
NOTE:
The procedures of use of the printer desribed in this section are presented in alphabetical order.
If you need a guided printing procedure, see section 6 “First use of the printer”
8.1. Adhesion to the bed
The adhesion to the plate takes place during the deposition of the first layer and is essential for the success of
the printing.
Before reading this paragraph make sure to read and understand the paragraph 8.12 “VACS - Vaacum Active
Control System”.
The fundamental points of a good adhesion are:
• Good calibration of the printing bed
• Right printing plate or glue (based on the material to be printed)
• Adequate speed, flow and nozzle temperature in the first layer
• If necessary a temperature for the Firecap system (based on the material to be printed)
It is recommended to monitor the adhesion between first layer and bed during the first minutes of each print.
In order to control the sticking on the first layer some print settings can also be used:
• Raft: creates an interface structure before printing the actual part, improving a lot the adhesion and
resolving minor calibration imperfections.
• Brim: creates additional external perimeters on the base of the object increasing the sticking surface and
stabilizing the extrusion before the print.
• First layer height: the height of the first layer can be increased to resolve minor calibration issues
If the extrusion of the material on the first layer is particularly scarce or even absent, check that:
• The extruder is not clogged, with the procedure displayed in paragraph 8.7 Manual Control
• The extruder is not printing too close to the bed (preventing extrusion during the print)
• The extruder temperature is actually the one needed for the material in use
