Setting up hardware & Homing the printer

The touchscreen at the front will turn on. The screen will start making a system check and the welcome screen will appear a few seconds later.
  2. Slide the platform back onto the linear drive and tighten up the top screw.
  3. Open one of the vats from the top side to avoid damaging the vat film and place the vat centrally over the screen.
  4. On the touchscreen press Maintain then Home to home the printer. 

 

Note: If you do not have a display port connection you can use a display port to HDMI adaptor. VGA connections are not supported.

Setting up a Print

Filling the Vat with Resin 

Note: Always wear gloves when handling the resin

1. Once you have the printer assembled and connected then press + 10 and pour your sample resin, which comes in the ancillary box, into the vat. Once poured then press – 10.

2. With the vat filled with resin place the hood onto the printer.

Note: If you have an object that is 100 cm3 then it will use 115g of resin. Always overfill by at least 20% to ensure consistent resin flow. For most prints, filling the vatto 1/3 full is more than enough. Place the hood back on the printer.

Note: Don’t remove the hood during the operation or the print will stop.

Starting a Test Print

Now you have set up your printer lets make your very first print! Your LC HR2 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 homepage, press the Print button, which will display the following screen.
  2. Click the test file Ring.cws to highlight it and press Print!. The print will then start.

If you are having or still experiencing issues please contact our technical support team here.

Post Processing

Removing the Finished Part & Washing

1. When your print has finished, press the +50 button and the platform will rise to above the level of the vat.

 

2. Remove the hood again and with absorbent paper under it, remove the flex plate or build platform and set it down on the paper. Place the hood back on to protect the resin in the vat from light.

 

3. Gently remove any excess polymer with absorbent paper. The fastest way to clean it and achieve a dry surface is by removing the flex plate and spraying or immersing it in Photocentric Resin Cleaner, which can be purchased from our store. Alternatively, you can wash it in hot water and detergent. Hold the flex plate under running hot water and gently clean the part with a soft brush or sponge and liquid detergent. Then remove the object by twisting the flex plate and cut off the supports. Take care not to damage it, it will not achieve full hardness until after post exposing in light. An ultrasonic cleaner is
useful to clean delicate objects.

Post Exposing

When clean of residual resin, place in water of Aprox. 60ºC, and leave under UV unit for ideally 2 hours. For optimum post-cure results, replace the water with hot water as needed. Longer may be needed if using Daylight not UV. Remove from water and dry.

 

Note: If you’re printing dental prints, something delicate or you wish for your print to stay in its constructed shape, you will need to complete the post exposure in water whilst the print is still attached to the platform.

2 hours post exposure

If you are having or still experiencing issues please contact our technical support team here.

Preparing for the next print

Follow the instructions below or watch the video here

1. Chip off any cured resin and clean the flex plate and platform with hot water and liquid detergent. Dry it thoroughly before inserting back into printer. Ensure the build platform is placed on the printer with the Serial Number sticker to the rear. Also, make sure the flex plate is placed back on the platform with the wings extending upwards.

 

2. Empty the vat and clean it after every print in case you have any solid pieces on the bottom as these would prevent the platform from homing correctly. Lift the vat from the printer; pour the resin back into the bottle through the filter paper into the funnel provided.

 

3. If you have a leak on the screen mop up the liquid resin immediately using absorbent paper. Clean off with a damp cloth with detergent. Hardened resin can be removed by chipping off with a credit card or plastic scraper (provided in the ancillary box. Metal scrapers should only be used with extreme care to avoid scratching the screen.

 

4. The build platform is labelled with the Serial # of the printer that it was supplied with. If you are using more than one printer, it is important to ensure that the correct build platform is placed back on the corresponding printer. The homing of the platform is performed during factory production, however, if rehoming is necessary, follow the instructions below.

Re-homing the platform

It is necessary to follow the homing set-up if a new build platform is being used or if an existing platform is to be used on a different printer. It is also, recommended that re-homing is completed after 100 prints approximately.

1. With the build platform completely removed, press the maintain button then press the home button.

 

2. Loosen the three adjustment screws on top of the print arm with an allen key.

 

3. Replace the build platform ensuring the Serial Number sticker is to the rear and that the flex plate is fitted. Do not tighten the central lever yet. Tighten each adjustment screw until resistance is met, do not over tighten.

 

4. Now tighten the central lever. Use the control panel to raise the platform, ensuring it lifts evenly. If it does not, repeat the homing procedure.

 

5. Apply locklite threadlocker to the three screws.

Re-Skinning 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.
