- Operate the printer in a well-ventilated area to avoid inhaling resin fumes.
- Tenez l'imprimante à l'écart de la lumière directe du soleil, des sources de chaleur et des matériaux inflammables.
- Ne touchez pas les pièces mobiles pendant le fonctionnement.
- Assurez-vous que l'alimentation électrique est correctement dimensionnée pour votre région et correctement mise à la terre.
- Tenir hors de portée des enfants et des animaux domestiques.
- Éliminer la résine non polymérisée et les déchets conformément à la réglementation locale.
3. Installation
3.1 Déballage et inspection
Carefully remove all components from the packaging. Inspect the printer and accessories for any signs of damage during transit. If any damage is found, contact customer support immediately.
3.2 Identification des composants
Familiarize yourself with the main components of your ELEGOO Mars 5 Ultra 3D printer:
- Unité d'impression
- Plaque de construction
- Resin Tank (Vat) with dual pour spouts
- Adaptateur secteur
- Clé USB
- Scraper, Gloves, Funnel, Mask
3.3 Assemblage initial
The Mars 5 Ultra comes largely pre-assembled. Attach the build plate to the Z-axis arm using the quick-release mechanism. Ensure it is securely fastened. Place the resin tank onto the LCD screen, aligning it correctly.
3.4 Mise à niveau automatique
The ELEGOO Mars 5 Ultra features an intelligent mechanical sensor for automatic leveling. Follow these steps:
- Allumez l'imprimante.
- Navigate to the 'Tools' menu on the capacitive touchscreen.
- Select 'Leveling' or 'Auto-Level' option. The printer will automatically detect the build plate position and calibrate itself.
- Confirm the leveling process is complete on the screen.

3.5 Chargement de résine
Before loading resin, ensure the resin tank is clean and free of debris. Gently pour the desired resin into the resin tank, ensuring it does not exceed the maximum fill line. The dual pour spouts facilitate easier pouring and draining.
4. Fonctionnement
4.1 Préparation de votre modèle pour l'impression
Use a compatible slicing software (e.g., Chitubox) to prepare your 3D model. Ensure the model is properly oriented, supported, and sliced according to the printer's specifications and resin type. Save the sliced file to a USB drive or transfer it via Wi-Fi.
4.2 Démarrage d'une impression
- Insert the USB drive into the printer or ensure Wi-Fi connection is established.
- On the touchscreen, select 'Print' and choose your desired file.
- Confirm print settings. The printer supports switching between fast and slow printing modes for optimal quality or speed.
- Initiate the print. The printer will begin the printing process, utilizing its advanced tilt release technology for faster layer separation.

4.3 Monitoring with AI Camera
The built-in AI camera provides real-time monitoring of your print progress. Access the camera feed through the printer's interface or a connected device. The AI camera can detect issues such as empty build plates or model warping, alerting you to potential problems.

4.4 Impression en cluster Wi-Fi et mises à jour du micrologiciel
The Mars 5 Ultra supports Wi-Fi connectivity for file transfers and remote control. Multiple printers can be connected to the same LAN for cluster printing, allowing for efficient management of multiple print jobs. Firmware updates can be performed wirelessly via OTA (Over-The-Air) for convenient system upgrades.

4.5 Fonction de reprise d'impression
En cas de panne de couranttage during printing, the Mars 5 Ultra can resume the printing process once power is restored. After powering on, select 'Continue Printing' from the menu to resume your job.
5. Entretien
Un entretien régulier assure la longévité et les performances optimales de votre imprimante 3D.
5.1 Nettoyage du réservoir de résine et du plateau d'impression
- After each print, carefully remove the build plate and scrape off any remaining resin. Clean the build plate with isopropyl alcohol (IPA).
- If changing resin types or if the resin tank has been idle for an extended period, drain the resin using the dual pour spouts and clean the tank with IPA.
- Inspect the FEP film (release film) in the resin tank for damage or cloudiness. Replace if necessary.
5.2 Nettoyage de l'écran LCD
Gently wipe the LCD screen with a soft, lint-free cloth and IPA. Avoid using abrasive materials or excessive force, as this can damage the screen or its protective film. A 9h replaceable scratch-resistant film is installed for added protection.
5.3 Z-Axis Maintenance
Periodically inspect the Z-axis lead screw for dust or resin residue. Clean and apply a small amount of lubricant if needed to ensure smooth movement.
6. Dépannage
This section addresses common issues you might encounter with your ELEGOO Mars 5 Ultra 3D printer.
6.1 Printing Errors and Warnings
The intelligent mechanical sensor provides warnings for various printing anomalies:
- Insufficient Resin Detected: If the printer detects low resin levels, it will prompt you to add more.
- Foreign Objects Detected: The sensor can identify foreign objects in the resin tank. Remove them before continuing to prevent damage.
- Release Film Replacement Needed: The printer may indicate when the FEP film requires replacement due to wear.
- Elevated Light Board Temperatures: The printer will stop operation if the lamp board temperature exceeds 80°C until it cools down, protecting components from overheating.

6.2 Problèmes d'impression courants
- Impressions ne collant pas au plateau : Ensure the build plate is clean and properly leveled. Increase bottom exposure time in your slicer settings. The laser-engraved platform is designed to enhance model adhesion.
- Failed prints or partial prints: Check resin exposure settings, FEP film condition, and ensure the resin is well-mixed.
- Layer lines or poor detail: Verify your model's supports, resin settings, and ensure the printer is on a stable surface. The 9K mono LCD with 18*18μm XY resolution is designed for excellent detail.
6.3 Problèmes d'alimentation et de démarrage
If the printer gets stuck at the boot screen or experiences UV LED issues, try the following:
- Perform a hard reset by unplugging and replugging the power cable.
- Ensure the firmware is up to date. If issues persist, attempt to re-flash the firmware via USB from the official ELEGOO website.
- If the UV LED is not working, check connections and consult ELEGOO support.
