2. Turn on the printer using the rocker switch at the back of the printer.

3. Take the pre-homed platform from the accessory box, unpack completely, slide it over the arm and tighten the knob.

4. Take one vat from the accessory box, unwrap carefully, and place it centrally over the screen.Your printer is all set and ready to use! 

Notes:

DO NOT remove the protective film covering the screen. In the event of any resin spillage clean with a damp and soapy cloth. If you damage the film,
replacements are available from Photocentric or your reseller.

To unplug the printer from the power, first turn off and unplug the power cord from the wall socket. Wait for 10 minutes to allow full discharge (small blue LED light on the power supply should go off), then disconnect the plug from the printer. 

If you want to remove the cable, you need to hold the collar and pull it back.

Starting A Test Print

Filling the Vat with Resin 

Note: Always wear gloves when handling the resin

1. Take your 250g sample resin bottle, shake it and pour the contents into the vat.

2. Place the hood onto the printer

Starting a Test Print

Now you have set up your printer lets make your very first print! Your LC Precision 1.5 has been shipped with a default test print pre-loaded. For your first print use this print and the sample resin supplied with your printer which you have just filled into the vat.

1. On the touchscreen, press the Print button, which will display the following screen.

2. Click the test file LC Precision 1.5 test file.cws to highlight it and press Print!. The print will then start.

3. Once the print job is completed, the platform will move back up to the home position and you can start the cleaning process. (Refer to the cleaning section on this page)

Note: The software may take a few seconds to calculate the print duration. The correct print time will be calculated after the completion of the bottom layer.

Post Processing

Removing the Finished Part & Washing

1. Remove the hood

2. Take off the platform. Place the hood back onto the printer to protect the resin in the vat from light.

3. Wipe excess resin from the platform off with absorbent paper. Hold the platform over a sink, spray warm soapy water or Photocentric Resin Cleaner over parts to clean off excess of resin.

4. You can rinse off the rest of resin with hot water. Be gentle with delicate parts. Water pressure may damage them.

5. Once cleaned, you shouldn’t be able to see any trace of uncured resin.

6. If you have access to an air compressor with an air gun, you can dry your parts after cleaning. We recommend this for delicate and accurate parts to ensure all holes and pores are free of any traces of uncured resin.

 

Post Exposing

1. Gently remove the parts from platform by sliding the scraper (provided) underneath parts.

Note: Depending on your application, you can remove supports at this stage or leave them on during the post exposure process. For jewellery applications, we recommend removing the supports when parts are soft (before post exposure) to avoid leaving support marks on parts.

2. Place parts underwater in light (UV, sunlight or a table light) for a least 30 minutes to remove the surface tack. Parts get fully hardened by being under UV light for 2 hours and in hot water (140°F).

3. Once post exposure is complete, dry the parts and your print is complete.

Note: For any applications where accuracy of parts is critical (like dental use), we recommend post exposing in water and under light while parts are still attached to the platform.

 

Reskinning The Vat

Note: This procedure is optional. New disposable vats can be purchased from our store

 

You will need:

Scissors
Craft knife
Pallet knife
Photocentric vat film (Purchase here)
Single sided sticky tape
Double sided tape
Paper towel

Please read carefully.

Re-skinning the vat is a simple process but care and attention must be paid to cleanliness and removing cured bits of resin. Make sure at each stage of the process that the work surface, vat, and your hands are very clean and free from debris that may cause holes in the film.

1. Remove the film currently taped to the vat and dispose of it. It may be possible to use the double-sided tape again if it has no resin on it. If the tape cannot be reused, remove it completely and replace on the lower edge of the vat.

2. Wipe the vat clean and wash all parts with soap and water. Pay attention to the underside of the vat, resin may have cured here. Remove any hard bits of resin as they may make a hole when tightening the new film over it.

3. Place double sided tape at the top of all four sides of the vat. Check the new vat film isn’t pierced or dented and place it over the protective brown paper, on a flat work surface. Place one edge of the vat along the edge of vat film.

4. Fold over the other side of the film and pulling it firmly tight in the middle stretch the edges out so there are no creases.

5. Pull each side of the film up and onto the sides of the vat.

6. Apply single sided tape at the corners over the folds to keep the film tight. The vat should now be tensioned. Trim excess edges off. On the short sides of the vat place a piece of single sided tape.

7. Finally, fill with water and leave on absorbent paper to check for leaks. Drain and dry with paper towel before use.

Maintenance

Print Platform Calibration

We recommend you calibrate your platform every 100 prints. An uncalibrated platform may lead to failures due to first layers not attaching to the build plate or shifting layers during print.

1. Select Maintain on the screen menu.

2. Press Calibrate Platform and follow screen instructions carefully.

3. Loosely lock the bolts in the orientation as shown in figure 1 and then tighten them all fully.

4. When you press Finish your calibration will be complete and your LC Precision 1.5 is once more ready for use.

General Maintenance

1. It is extremely important to keep the top surface of your printer clean. If the screen film gets damaged please replace it.

2. Please vacuum the two chassis fans (rear panel and bottom fans) every two months. It is important to keep fans dust free and avoid overheating the electronic parts.

 

Troubleshooting

  1. Nothing or not everything is appearing on the platform

Homing – if your platform is not properly homed then this will cause parts to not fully adhere across the platform. Indications that this is a homing issue is when you have parts adhering to one side of the platform but not both. Please note, if this is a homing issue you should have bits of cured resin in the vat on the side where nothing has attached to the build plate. If you do not have any cured resin in the vat then your LCD screen could have become damaged – to check this please run a dry print. It is also worth noting, if you have the base layers of all your parts adhering to the platform then this is not a homing issue and likely an error with the file or the supports.   

  1. Part is not attaching to the supports
  • If your part has not printed successfully but the supports have then this suggests that the tips are too small for the model you are printing, we advise the below support tips and bodies as a minimum safe recommendation. 
  • To solve this issue just increase the thickness of your support tips and bodies and your part will evenly attach to your supports.  

  1. Print has failed 
  • Vat leak – if a vat leak has occurred, you’ll likely have interference (as above) as well, this is essentially where you vat film has become pierced or damaged beyond use. We would advise re-skinning your vat and fully cleaning down both the screen protector and vat. 
  • Not enough supports – if there are not enough supports then your part will fail as it cannot evenly attach to the supports forcing it to fail and cure in the vat. If this is the case either your quantity of supports will need to be increased or the thickness of your support tips and bodies will need to be increased. 

  

  1. Random stray “strips” curing in the vat 
  • It is likely that there is a bit of light leakage occurring around your LCD screen, this is caused when the plastic shim has moved slightly either during printing or transit allowing a tiny line of light to appear and cure some of the resin in your vat. 

  

  1. Castable violet prints failing 
  • Castable violet and red resins have a wax-based element that can be affected by climate, if your climate becomes too cold then your resin can experience minor wax separation. To solve this issue, you’ll need to heat your resin to 140°F for approximately 4 hours. Once it has been heated please shake your bottle thoroughly to ensure this separation is re-absorbed, this will then be ready for printing.
