Leveling Procedure

1. Take out the printer carefully and remove any protective film.
2. Turn on the printer.
3. Insert the build platform, fasten the rotary knob, and loosen the screws. Diagram showing the build platform being attached to the Z-axis.
4. Remove the resin tank. Place an A4 paper between the build platform and the 4K LCD screen. Click "Move Z axis to zero" on the touchscreen. Diagram showing an A4 paper placed between the build platform and the LCD screen.
5. When the build platform stops moving, use one hand to press it gently to ensure it is centered, then fasten it using the Allen Wrench. Illustration showing how to fasten screws on the build platform after leveling.
6. Since tightening the screws of the build plate can affect the leveling, you may need to calibrate the Z axis height slightly again.
   • If there is no resistance or only slight resistance when pulling out the A4 paper, click to descend the Z axis by 0.1mm.
   • If the paper cannot be pulled out or the resistance is very high, click to raise the Z axis by 0.1mm.
   • If there is some resistance but you can still pull the paper out with slight effort, stop adjusting the Z axis.

7. After the leveling is complete, set the current Z axis position as the initial height for the first layer of printing. Return to the previous interface and click "Set Z=0". A confirmation message will appear; click "Confirm" to complete. UI screens showing the 'Set Z=0' option and the confirmation dialog.
8. Press "10mm" then press "up" for 10 times; the Z axis will go up about 100mm. UI screen showing Z-axis movement controls.
9. Test the lights by pressing "Tool" -> "Exposure" -> "Next". UI screens for testing light exposure. If the 4K screen displays a complete "ELEGOO TECHNOLOGY www.elegoo.com", the UV lights are working perfectly.
10. Put the resin tank back and fasten the screws. Diagram showing the resin tank being placed back onto the printer.

Print Test

1 Model Printing (Cover the machine with the anti-UV cover.)

Please be careful to remove the protective film from the touch screen panel.

Put on a face mask and gloves first (to avoid direct skin contact). Slowly add resin to the max line of the tank, ensuring it does not exceed the max line. Cover the printer with the anti-UV cover to protect it from UV light. Make sure the printer is level and does not wobble. Plug the USB into the printer, select the model file "Rook.ctb" and start printing. Illustration of the Mars 3 printer with the anti-UV cover on.

UI screens showing options for selecting and starting a print job.

If you find that there is not enough resin to complete the model during printing, you can press the "Pause" button, add more resin to the tank, and then press "Print" to continue printing.

Wash Your Print and Clean the Tank

Once printing is completed, please wait until the resin on the build platform doesn't drip any more. Loosen the rotary knob and remove the build platform. Use the scrapper to remove the model. Wash the model with 95% ethyl alcohol or isopropyl alcohol if you are using standard resin or ABS-like resin. Diagram showing how to remove a printed model from the build platform using a scrapper.

ELEGOO ChiTu Box Software

1 Install ChiTu Box

ELEGOO ChiTu Box is saved in the U Disk. Choose the right version and install it on your computer, or you can download the latest version from www.elegoo.com/download if you prefer.

2 How To Use ChiTu Box

After installation, run ChiTu software. Click File -> Open File, then open your own 3D model files (.stl type) or download some samples from www.elegoo.com. You can control and change the visual angle, size, and position of the model by left-clicking the model and using the options on the left menu.

Other operations:

1. Long press the left click and drag the model to the desired position.
2. Scroll the mouse wheel to zoom in or out on the model.
3. Long press the right click to see different perspectives of the model.

3 ChiTu Box Setting

3.1 Click "Parameter Settings" and choose ELEGOO Mars 3 as your default printer. Screenshot of ChiTu Box software showing machine selection, with ELEGOO MARS 3 highlighted.

3.2 Build Volume

Below are the default parameters, and you don't need to change them. If the model is bigger than the printer's build volume, you would need to change its size with the ratio locked. Screenshot of ChiTu Box software showing printer settings including resolution, size, and build area.

3.3 Resin Parameter

Resin Density: 1.1g/ml

Resin Cost: You can input the cost of resin, and after slicing, you will see how much it cost for your model. Screenshot of ChiTu Box software showing resin parameter settings like density and cost.

3.4 Parameters

The recommended Layer Height is 0.05mm, but you can set it from 0.01-0.2mm. The higher you set, the longer time it will take for exposure of each layer.

• Layer Count: Set as 3-6 layers.
• Exposure Time: Can be set as 1.5-3s depending on the height of the layer and the complexity of the model. The thicker the setting, the more the bottom will stick to the build platform.
• Bottom Exposure Time: Can be set as 20-40s. The longer the setting, the more the bottom will stick to the build platform.
• Transition Layer: Default parameter and does not need to be changed.
• Transition Type: The default parameter is linear and does not need to be changed.
• Waiting Mode Of Printing Process: Default parameter is static and does not need to be changed.
• The quiescent time after retract: Default parameter is 0 and does not need to be changed.
• Bottom Lift Distance: When printing the bottom layers, it is recommended to set the lifting distance of the build plate to 3-5mm.
• Lifting Distance: When printing the normal layers, it is recommended to set the lifting distance of the build plate to 3-5mm.
• Bottom Lift Speed: When printing the bottom layers, it is recommended to set the lifting speed of the build plate to 80mm/min.
• Lifting Speed: When printing the normal layers, it is recommended to set the lifting speed of the build plate to 110mm/min.
• Retract Speed: When printing the bottom layers, it is recommended to set the retract speed of the build plate to 280mm/min.

4 Save Model

After setting up all the parameters, click "slice". Once it's done, click "export sliced files to U Disk or SD Card", then plug the U disk into your printer and start printing. 3D rendering of sliced models within the ChiTu Box software, showing placement on the build platform.

FAQ (Frequently Asked Questions)

1. Model doesn't stick to the build platform
   • Bottom layer exposure time is too short; please set the exposure time longer.
   • Model bottom has very small contact with the build platform; please add more bottom layers.
   • Leveling is not well set, which can cause the first layer to be too thick or one side to be very thick and the other side very thin.
2. Model layer breakage
   • The printer is shaking during printing.
   • The release liner film is very loose due to long-time usage and needs to be changed.
   • The build platform or resin tank is not fastened securely.
3. Mars 3 can't work
   • ELEGOO offers a full one-year warranty on the printer and a 6-month warranty on the screen.
   • If your printer doesn't work, please contact ELEGOO at 3dp@elegoo.com. To help solve problems, please add your order ID in your email.
4. Printing failure
   • If the model was not completely printed or failed, there might be some residues left in the resin. These can be filtered out using a funnel when saving the rest of the resin back into its sealed bottle. If you don't filter out the residues, the platform may cause damage to the 4K screen when you're printing next time. As for the leftover resin on the platform and in the tank, you can clean and wipe them up using tissues.

Maintenance

1. If the Z axis keeps making friction noises, please apply some lubricant to it.
2. Please do not use sharp or pointy objects to scrape the release liner film to avoid damages. Illustration showing a scrapper with a red cross symbol, indicating not to use sharp objects on the release liner film.
3. Be careful when you remove the build platform to avoid damaging the 4K LCD screen.
4. Remember to pour the rest of the resin from the tank back into the resin bottle and seal it well if you don't use the printer in the next 48 hours. And if there are any residues, please use a filter to filter them out. Diagram showing resin being poured from the tank through a filter into a bottle.
5. Please clean up the build platform and the printer using tissues or ethyl alcohol once you complete printing.
6. Please clean up the resin tank before changing to another color of resin.
