6. Sandblasting the printouts
ATTENTION!
•
Before starting any job with Sinterit SANDBLASTER XL, always wear Protective
Glasses, Protective Dust mask, and optional gloves.
•
You can use use the “PERSONAL PROTECTION” set included with Sinterit Lisa printers.
ATTENTION!
•
It is strongly forbidden to start sandblasting when the sandblaster is not fully closed
(open door) or when LED light
18
is not on.
•
Make sure the Power switch
1
is OFF-position before plugging in the machine.
•
The Inner Air Blow Gun
20
and external Air Blow Gun
D
should always point away
from the operator to the workpiece.
IMPORTANT!
•
Before you can start sandblasting make sure the printout is free of oil, water and
moisture.
•
The Abrasive Material should be moist free. Moist grit clutters, which causes a bad
flow and clogging.
1. Turn on the compressor and the Sinterit SANDBLASTER XL.
2. Check all the pneumatic tubings and joints for leaks. If they appear, replace the element or seal it with PVC tape
E
or Teflon tape (not available in the set).

IMPORTANT!
•
Use the Inner Air Blow Gun
20
only for large and strong prints.
•
The Static Nozzle
19
is ideal for standard and fragile prints.
•
By default, ceramic nozzle no. 5 is installed in the Inner Air Blow Gun. You can also choose
to use a larger or smaller ceramic nozzle (available in the Accessory box).
•
Nozzles smaller than No. 5 do not work precisely with the Sinterit Abrasive material.
•
A bigger size ceramic nozzle gets the job done faster because it can blast a larger surface,
this also causes a higher air consumption, make sure the compressor can handle it.
6. Use the Pneumatic pressure regulator
3
and the Pressure gauge
5
and set the work pressure of the compressed
air between 5 and 8.6 bar (58-125 psi). You can start with a working pressure of 4-5 bar, then most workpieces can
be blasted easily with this pressure.
