6. Sandblasting the printouts
1. Turn on the compressor and the Sinterit
SANDBLASTER.
2. Check all the pneumatic tubings and joints for leaks.
If they appear, replace the element or seal it with
Teon tape.
3. Put on the Protective Dust Mask and Protective
Glasses (e.g. you can use the „PERSONAL
PROTECTION” set included with Lisa printers).
4. Open the SANDBLASTER lid 6and insert the printout
into the chamber 11 , under the Nozzle 5.
5. Close the SANDBLASTER’s lid 6 rmly.
6. Use the Pneumatic pressure regulator 9and the
Pressure gauge 1to set the desired pressure in
the range of 0.8-0.6 [MPa] (87-116 [Psi]). In order to
adjust the cleaning intensity, unlock the regulating
device by pulling the Pneumatic pressure regulator,
and use the indications of the Pressure gauge to
select an appropriate value. After performing the
adjustment, lock the Pneumatic pressure regulator
by pressing the knob.
Image 6. Unblocking the Pneumatic pressure regulator.
ATTENTION!
Adjust the sandblasting intensity appropriately, depending on the type of the object to be cleaned.
• For solid, thick-walled objects, the pressure may be near the maximum, which
is 0.8 [MPa] (116 [Psi]).
• For objects with an openwork structure, it is recommended to lower the pressure
to 0.6 [MPa] (87 [Psi]). If, despite lowering the pressure, the object becomes damaged, se-
lect a lower pressure value empirically, as appropriate.
7. Put your hands into the Protective Rubber Gloves 2, grab the printout and begin cleaning by pressing the Control
pedal J.
8. Sandblast the printout with a continuous stream of air, moving the printout in circular motions until all unnecessary
powder is removed.
9. After cleaning the printout, wait a moment, for the dust to fall. Open the lid and take out the sandblasted object.
Close the lid.
10. All remaining powder and abrasive material can be blown out from the printout with the Air blow gun G.
11. When the work is nished, turn off the pressure to 0 [MPa] (0 [Psi]) and switch off the SANDBLASTER.
7. Maintenance of the Sinterit SANDBLASTER
• There is no need for maintenance after each use. All replacements on need.
• Before performing the maintenance of the device, disconnect the power and the compressed air.
• Clean the lid and the parts of the SANDBLASTER with a soft cloth. Do not use any solvents for cleaning!
• Avoid allowing moisture into the abrasive material, as it may cause clogging of the Nozzle.
A. THE VIEWING WINDOWOF THE SANDBLASTER LID
• Use a soft cloth or paper towels to clean the SANDBLASTER viewing window.
• When the PE protective foil Dbecomes matt (fogged), which makes it impossible to see the SANDBLASTER
chamber 11 , the foil should be replaced with a new one (the three spare PE protective foils are available in
additional accessories of the SANDBLASTER).
- Remove the old PE protective foil.
- Clean the inside of the SANDBLASTER lid 6and the viewing window with a soft cloth (it is best to soak it with
alcohol).
- Wait until all it dries and carefully place the new PE protective foil D.
