HOUSEKEEPING

To set-up for your next print, the housekeeping activities should be taken into consideration. Please see below.

CLEANING THE RESIN VAT

1. After printing, resin should be removed from the vat to ensure there are no fragments of cured resin to print.

2. Take the resin bottle used for the previous print and remove the cap.

3. neck of the bottle.
   NOTE: With some resin bottle sizes, both parts of the cap will need to be removed in order to make room for the funnel.

4. Carefully remove the resin vat from the printer.

5. Tilt the vat towards the corner with the pouring

6. Once most of the resin has poured away, use the vat cleaning tool to guide the remaining resin to the corner of the vat.

7. with paper towel.

8. Place vat on suitable clean, smooth surface (e.g. the provided silicone mat).

9. Use paper towel to soak up the last of the resin in the vat.

10. Use a small amount of suitable cleaning solvent walls. Dry them thoroughly.

11. Check for any fragments of cured resin using the soft spatula provided.

12. you have any doubt about the condition of the vat
    NOTE: Printing with a damaged vat will cause failures and leaks causing permanent damage to the printer.

13.  Check the screen of your LC Opus for any sign of resin contamination or damage.

14.  If resin is present, clean thoroughly using paper towel and the provided pallet knife if needed, this needs replacing.
    NOTE: If you believe your printer’s screen may be damaged, contact your supplier or visit the support pages of the Photocentric website.

15. Store the resin vat in the printer when not in use.
    Alternatively, use the ‘Cure Resin Layer’ feature to clean the resin vat. This function assists with the removal of debris without further damage to the following:

16. Select ‘Maintain’ from the Main Page on the GUI.

17.  Select ‘Cure Resin Layer’ from the Maintain Page.

18.  The screen will cure a layer of resin at the bottom of the resin vat.

19.  Follow steps 2-15 of the above Section, ensuring the cured resin layer is removed from the vat using the palette knife or vat cleaning tool provided.

CLEANING THE PRINT PLATFORM

After printed parts have been harvested, it is vital that the print platform is cleaned thoroughly before being used again.

1. If any Photocentric Resin Cleaner or residual suitable cleaning solvent and paper towel.

2. 2. Cured resin should be removed from the platform using the scraper provided.
   3. Ensure there is no cured resin blocking the holes
   NOTE:
   Observation of burrs or pickups on the platform indicate that it will need to be sanded. The sanding should be minimal to avoid degrading the surface of the platform and its parallelism. We recommend 60 grit sanding paper.

3. 4. If available, use compressed air to remove loose debris from the platform and platform holes to avoid
   5. When not in use, the platform should be stored inside of the printer.

MAINTENANCE

GENERAL MAINTENANCE

The main air intake for LC Opus’ cooling system is on the base of the printer. Over time, dust will overheat. This will eventually trigger the thermal cut- out and cause a print failure. The LCD screen may also be permanently damaged. is in regular use. For printers in constant use or in from the base plate and replaced without tools. To get access, you will need to elevate the front of the machine. Always make sure the vat is empty and the hood is closed before lifting or moving LC Opus. Ask another person to help you and observe proper lifting practice. The printer weighs 38 kg. Use warm has dried fully. LC Opus will work consistently as long as it is kept clean at all times. Any equipment to be used alongside this printer e.g., resin bottles, gloves, tools etc should be kept clean. For further information, please visit our website:

PRINT PLATFORM AND RESIN VAT 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 resin vat LCD are all in contact once the platform reaches the end of its movement to the bottom. The platform and vat should not become misaligned during your time using LC Opus. In the rare event that misalignment occurs, you will need to reset the printer platform and vat to their correct positions. You will need: T25 L-Shape Torx Key
NOTE: When purchasing secondary print platforms and resin vats, they do NOT need to be re-calibrated. Both can be used interchangeably from printer to printer.
Print Platform Re-Calibration
To watch a video on Print Platform Re-Calibration click here.

1. Remove the resin vat from the printer.

2. Ensure the print platform and screen are completely clean, failure to do so could lead to damage of the screen or inaccurate homing leading to print failures.

3. Secure the print platform into the printer by tightening the turn knob.

4. On the ‘Main’ screen, select ‘Maintain’.
   

5. Select ‘ReCalibrate’.

6.  Select ‘Platform’.
   

7. Close the printer hood and select ‘Start’.
