Leveling

1. Take out the printer carefully and take off the plastic film.
2. Turn on the printer.
3. Please insert the build platform, fasten the rotary knob, and loose the screws (see picture 1).
4. Remove the resin tank and put an A4 paper between the build platform and 4K LCD screen and click“ Move Z axis to zero” (See picture 2). When the build platform stops please use one hand to press it and make sure it’s in the central position then fasten it using the Allen Wrench. (See picture 3)
5. Since tightening the screws of the build plate it will be tighter when pulling out the A4 paper,at that time, you need to calibrate the height of the Z axis slightly again. If there is no resistance or only a few resistance when pulling out the A4 paper, click to descend the Z axis at a distance of 0.1mm. If the paper cannot be pulled out or the resistance is very high, then you should click to rise the Z axis at the distance of 0.1mm.If there is some resistance but you can still pull it out with slight efforts, then stop adjusting Z axis. (See picture 4)
6. After the above leveling is completed, set the current Z-axis position as the initial height if the first layer of printing. The operation is as follows: Return to the previous interface and click“ Set Z=0”. At this time, the screen will pop up a message as shown in the picture. Then click“ Confirm” to complete. (See picture 5)
7. Press“ 10mm”-then press“ up” for 10 times, then Z axis will go up about 100mm.(See picture 6)
8. Test the lights by pressing“ Tool”-” Exposure”-” Next” (See picture 7). If the 4K screen can display a complete“ ELEGOO TECHNOLOGY www.elegoo.com”then the UV lights work perfectly.

Print Test

1. Model Printing (Cover the machine with the anti-UV cover.)
   Please put on a face mask and gloves first (to avoid direct contact with the skin), then slowly add resin to the max line of the tank and the resin should not exceed the max line, cover it with an anti-UV cover to protect it from UV light and make sure the printer is level and does not wobble, plug the USB into the printer, select the model file “Rock.ctb” and start printing .
   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.

2. Wash Your Print and Clean the Tank
   Once printing is completed please wait until the resin on the build platform doesn’t drop anymore. Lose the rotary knob and remove the build platform. Use a scrapper to remove the model and wash it with 95% degree (or higher) ethyl alcohol if you are using standard resin or ABS-like resin. (See picture 9 )

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.

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

Other operations:

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

ChiTu Box Setting

1. Click“ Parameter Settings” and choose ELEGOO Mars 3 as your default printer.(See picture 10)

Build Volume
The below are the default parameters and you don’t need to change them. If the model is bigger than printer build volume you would need to change its size with ratio locked.(See picture 10)

Resin Parameter (See picture 11)

• Resin Density: 1.1g/ml
• Resin Cost: You can input the cost of resin and after slicing you will see how much it costs for your model.

Parameters (See picture 11)

• Layer Height: The recommended 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 is, the more the bottom will stick to the build platform.
• Bottom Exposure Time: This can be set as 20-40s, the longer the setting is, 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: The default parameter is static and does not need to be changed.
• The quiescent time after retract: The 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.

Save Model
After setting up all the parameters, click “slice” and once it’s done, click “export sliced files to U Disk or SD Card” then plug the U disk to your printer, start printing. (See picture 12)

FAQ

The model doesn’t stick to the build platform
The bottom layer exposure time is too short, please set the exposure time longer. Model bottom has very small contact with the build platform and please add more bottom layers. Leveling is not well set and it will cause the layer too thick or one side is very thick and the other side is very thin.

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.

Mars 3 can’t work
We offer a full one-year warranty on the printer and a 6-month warranty for the screen. If your printer doesn’t work please contact us at 3dp@elegoo.com as to better help and solve problems for you please add your order ID in your email.

Printing failure
If the model was not completely printed or failed, there might be some residues left in the resin, which can be filtered out using a funnel when you save the rest 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 to the left resin on the platform and tank, you can clean and wipe them up using tissues.

Maintenance

1. If the Z axis keeps making friction noises, please add some lubricant to it.
2. Please do not use sharp or pointy objects to scrape the release liner film in case of damage.
3. Be careful when you remove the build platform in case you may damage 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.
5. Please clean up the build platform by using tissues or ethyl alcohol once you complete printing.
6. Please clean up the resin tank before changing another color of resin.

Warranty Service

1. ELEGOO provides a 1-year warranty for equipment damaged by non-human factors, except for filament, LCD screen, and FEP release film.
2. The LCD screen comes with a 6-month non-artificial damage warranty.
3. No warranty is provided for personal modification or disassembly of equipment.
