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.
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.
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.
Preparing For The Next Print
1. To prepare for the next print job, scrape off any cured resin and clean the build platform with hot water and liquid soap. Dry the platform. Now, your build platform is ready for your next print, with no extra adjustment.
2. Pour the remaining resin in the vat back into the bottle through the funnel using the filter paper provided.
3. Use the vat cleaning tool (white card) to direct any excess of resin from vat down to the funnel.
4. Place the vat on paper towels and mop up resin residue with absorbent paper. After you can clean with damp soapy paper.
5. Ensure you clean the vat thoroughly. Cured resin can easily pierce the vat film and adversely affect the homing of your next print. Ultimately you could damage the screen film and even your screen.
6. If you have a leak on the screen, mop up the liquid resin immediately using absorbent paper or a damp tissue with soapy water or IPA. Hardened resin can be removed by chipping off with provided white card or plastic scraper. Metal
scrapers should only be used with extreme care to avoid scratching the screen film. It is extremely important to keep your screen plate surface clean from any resin. If not, you risk print failures. Please refer to the video here for details on removing resin from the screen.
Reskinning The Vat
Note: This procedure is optional. New disposable vats can be purchased from our store
You will need:
Photocentric vat film (Purchase here)
Single sided sticky tape
Double sided tape
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.
