ELEGOO SATURN: How to replace the FEP

If your Saturn machine needs to replace the FEP, please follow the steps below.

Tools you need: 2.0mm Hex Wrench, 2.5mm Hex Wrench, 3.0mm Hex Wrench, Utility Knife, 80*80*8mm size Sponge, Gloves, New FEP


1) Remove the 4 screws circled in the picture.

2) Remove the 12 screws circled in the picture.

3) Remove the 24 screws that fix the FEP to the black frame.

4) Peel off the protective film from both sides of the new FEP.

5) Place one of the frame on the table, place the sponge(so that the FEP is at the approriate level of slack), place the FEP, place the other frame, then lock the 24 screws to secure.

Caution: Please note the install direction of the black frame (refer to the video for operation). The side with the larger opening of the 12 screw holes shall face the table surface.

6) Remove the excess film with the utility knife along the edge of the frame.

7) Put the FEP and the frame back on then lock all the screws.

    I have issues using your instructions for changing the FEP on my Saturn. Most of it is great however advising on which screws are tightened and the order is not mentioned. My inner frame seems buckled, possibly tightening in the wrong order. I am guessing this is the issue. I have now got a vat I am unable to use. I have already delayed printing as I am having issues printing. I have a Mars which has given me a lot fewer problems. Have you any suggestions.

    Yours faithfully,
