Comgrow Creality LD-002H UV Resin 3D Printer User Manual

1. Introduzione

Thank you for choosing the Comgrow Creality LD-002H UV Resin 3D Printer. This manual provides essential information for the safe and efficient operation of your device. Please read it thoroughly before use and keep it for future reference.

The LD-002H features a 2K HD LCD screen for high-precision printing, a robust Z-axis linear rail for stability, and an integrated air filtering system for improved working conditions. Its generous build volume of 130x82x160mm allows for a wide range of projects.

2. Impostazione

2.1 Disimballaggio e controllo dei componenti

Carefully remove all packaging materials. Verify that all components listed in the packing list are present and undamaged. If any parts are missing or damaged, contact customer support.

2.2 Posizionamento della stampante

Place the printer on a stable, level surface in a well-ventilated area. Ensure there is sufficient space around the printer for operation and maintenance. Avoid direct sunlight exposure.

2.3 Manual Leveling System

The LD-002H features a manual leveling system for precise calibration of the build plate.

1. Loosen the leveling nuts on the build plate.
2. Lower the build plate until it is close to the LCD screen.
3. Place a piece of A4 paper (approximately 0.1mm thick) between the build plate and the LCD screen.
4. Gently press down on the build plate to ensure it is level and the paper can be pulled with slight resistance.
5. Tighten the leveling nuts securely to fix the build plate in position.
6. Rimuovere la carta.

2.4 Z-axis Linear Rail

The Z-axis linear rail provides stable and precise vertical movement for the build plate, crucial for accurate layer adhesion and overall print quality. No assembly is typically required for this component, but ensure it is free from obstructions.

2.5 Software Installation (CHITU BOX)

The Comgrow Creality LD-002H utilizes CHITU BOX slicing software. Install the latest version from the official CHITU BOX website. This software allows you to prepare your 3D models for printing, add supports, and generate the necessary print files.

3. Istruzioni per l'uso

3.1 Preparing Your Model

1. Import your 3D model (e.g., .STL, .OBJ) into CHITU BOX.
2. Adjust the model's size, orientation, and position on the virtual build plate.
3. Generate supports as needed for overhangs and intricate details.
4. Slice the model, which converts it into layers and generates the print file (e.g., .cbddlp).
5. Save the print file su un'unità USB.

3.2 Loading Resin

1. Ensure the resin vat is clean and free of debris.
2. Shake the resin bottle thoroughly before opening.
3. Carefully pour the resin into the vat, ensuring it does not exceed the maximum fill line.
4. Quando si maneggia la resina, indossare sempre dispositivi di protezione individuale adeguati (guanti, occhiali di sicurezza).

3.3 Avvio di una stampa

1. Insert the USB drive containing your print file nella porta USB della stampante.
2. Power on the printer. The 3.5-inch intelligent color touch screen will display the main menu.
3. Navigate to the print menu and select your desired file dall'unità USB.
4. Confirm the print settings and start the printing process.
5. The printer will automatically lower the build plate and begin curing layers.

3.4 Post-elaborazione

1. Una volta completata la stampa, rimuovere con cautela la piastra di stampa dalla stampante.
2. Use a scraper to gently remove the printed model from the build plate.
3. Wash the model in isopropyl alcohol (IPA) to remove uncured resin. Multiple washes may be necessary.
4. Allow the model to dry completely.
5. Cure the model under a UV light source to fully harden the resin.
6. Remove any remaining supports.

4. Manutenzione

4.1 Pulizia della vasca di resina

After each print, inspect the resin vat for any cured resin particles. Use a plastic scraper to gently remove them. If changing resin types or storing the printer, empty and clean the vat thoroughly with IPA.

4.2 Pulizia della piastra di stampa

Clean the build plate with IPA after each print to remove any resin residue. Ensure it is completely dry before starting a new print.

4.3 Cura dello schermo LCD

The 2K HD LCD screen is a critical component. Avoid touching it directly. If cleaning is necessary, use a soft, lint-free cloth and a small amount of screen cleaner. Never use abrasive materials or excessive liquid.

4.4 Air Filtering System

The integrated air filtering system helps reduce resin odors. Periodically check and replace the activated carbon filter as recommended by the manufacturer to maintain its effectiveness.

5. Risoluzione Dei Problemi

5.1 Errori di stampa

• Il modello non si attacca alla piastra di costruzione: Re-level the build plate, increase bottom exposure time in slicer settings, or roughen the build plate surface slightly.
• Stampe parziali o strati mancanti: Check resin level, ensure the FEP film in the vat is clean and undamaged, verify LCD screen functionality, or increase normal exposure time.
• Distorted or inaccurate prints: Ensure the Z-axis linear rail is clean and lubricated, check for loose components, or recalibrate exposure settings.
• Leafing or cured resin in corners of vat: This can indicate UV light leakage or over-curing. Adjust exposure settings, ensure the resin vat is properly seated, and inspect the LCD screen for damage.

5.2 La stampante non risponde

• Controllare i collegamenti di alimentazione.
• Ensure the USB drive is properly inserted and formatted correctly (FAT32).
• Riavvia la stampante.

5.3 Problemi di odore

While the printer has an air filtering system, resin printing can still produce odors. Ensure adequate ventilation in your workspace. Consider replacing the air filter if odors persist.
