4. If available, use compressed air to remove loose
debris from the platform to avoid piercing the vat
film for future prints.
5. When not in use, the platform should be stored
inside of the printer.
10. MAINTENANCE
10.1 REPLACING THE
RESIN VAT FILM
In normal operation, you should replace the resin
vat film and gasket after approximately 20 prints.
You should immediately replace the film if there is
any visible damage or evidence of resin leakage.
Replacing the vat film will take approximately 40
minutes if the correct procedure is followed and the
correct tools are used. It is important to clean the vat
body thoroughly to avoid fragments of cured resin or
other contaminants damaging the newly fitted film.
A video for Replacing the Resin Vat Film is available
You will need:
-
Vat Cleaning Foam Mat
-
Paper Towel
-
Cleaning Solvent (e.g. Isopropyl Alcohol)
- Scraper
-
1x Vat Film

1x Vat Gasket
-
Pozi 1 Screwdriver

Pozi 2 Screwdriver
1. Find a clean, flat surface to work on.
2. Use the vat cleaning foam mat provided to cover
the surface and protect the vat from damage.
3. Clean the vat thoroughly to avoid dripping resin
when the vat is turned over.
4. Turn over the vat.
5. Remove the large vat screws using the Pozi 2
Screwdriver, keep them to one side.
6. Lift off the vat ring assembly and remove the vat
gasket.
7. Clean the vat body thoroughly, ensuring that no
cured resin or other contamination is present on the
surfaces that will contact the new film.
8. Remove the small vat screws using the Pozi 1
Screwdriver, keep them to one side.
10.2 PRINT PLATFORM
RE-CALIBRATION
The print platform has been pre-calibrated on our
production line according to strict QC procedures.
This ensures that the bottom surface of the print
platform is parallel with the LCD screen. The platform
should not become misaligned during your time
using Liquid Crystal Magna. However, misalignment
can happen if the print platform is dropped, specific
bolts are loosened etc.
Should there be a requirement for print platform re-
calibration, please contact our Support Team for
further guidance.

9. Lift off the top vat ring with larger countersunk
holes, remove the vat film and dispose of it.
10. Clean both vat rings thoroughly using paper
towel and cleaning solvent.
11. Ensure the vat cleaning foam mat is clean.
12. Lay the bottom ring down facing upwards.
13. Take a new piece of vat film from the pack and
lay it centrally over the ring.
14. Place the top ring onto the film with the
countersinks facing upwards, aligning the holes with
those on the bottom ring.
15. Secure the two rings together using the small
screws and Pozi 1 Screwdriver. Now the vat ring
assembly is ready for the next step.
16. Carefully pierce holes for the larger vat screws
using the tip of the screwdriver.
17. Apply a new vat gasket to the frame of the vat
and ensure the holes are aligned.
18. Place the vat ring assembly on top of the vat
gasket with the countersinks facing upwards.
19. Secure the vat ring assembly to the vat body using
the larger vat screws with the Pozi 2 screwdriver.
22. Check that no damage has been caused to the
new film during the assembly process.
23. The vat is ready to use.
20. Carefully cut away the excess film.
21. Check that the vat ring assembly sits flat against
the vat body with no visible gaps.
NOTE:
The screws should pierce the film as you begin
to tighten them. The film must be kept flat at all
times. It should not be under tension but there
must be no creases. There should be excess film
on all sides of the rings.
NOTE:
You can gently tap on the vat film with a fingertip
(not a fingernail) to check the tension. There
should be a high-pitched, resonant sound like a
small drum. If the film feels loose, the vat will not
function properly.
NOTE:
Tighten the screws in two phases. Fit all screws
loosely before fully tightening any. In both
phases, start with the corners, then the middle
of each edge. Finish the remaining screws in
opposite pairs.
