Safety

Universal Safety

• Be aware of your surroundings, especially when handling large materials.
• Do not approach anyone operating equipment. Stand patiently in their field of view.
• Use PPE, including filtration and eye protection, when handling dust or emptying dust/shaving containers.

Equipment-Specific Safety

• Keep the Mars 2 Pro 3D Printer and its accessories out of the reach of children.
• Fill the resin tank no less than 1/3 of its volume, but do not exceed the MAX line position.
• Place the printer in a dry environment and protect it from rain and moisture.
• If you run into an emergency during use, please turn off the power supply of the 3D printer first.
• Use the printer indoors and avoid direct sunlight and a dusty environment.
• Use 95% ethyl alcohol or isopropyl alcohol to wash your model unless you are using water washable resin.
• If the printing fails, you need to clean the excess cured resin in the resin tank and change the resin, otherwise, it may cause damage to the printer.
• When operating the 3D printer, please wear a mask and gloves to avoid direct skin contact with the photopolymer resin.
• If the release film in the resin tank is whitened, scratched, or has no elasticity, the printing failure rate is high, please replace the release film in time.
• Be careful when removing models with sharp edges from the build platform.
• If you have any problems with the printer, please report them to Asmbly via QR code.

Etiquette

The 3D printers do not have a daily limit on booking time, but the time spent with the printers should include not only the print time, but also the additional time needed for pre-print and post-print tasks. Please incorporate this extra time when booking the printers.

Resin Safety

• Wear gloves and mask when using.
• Keep away from children, dust and direct sunlight.
• May cause an allergic skin reaction. If skin contact occurs, wash thoroughly with plenty of soap and water.
• Causes serious eye irritation. In case of eye contact, use the emergency eye flush bottles located by the sink or rinse eyes with water for 20 minutes.
• Avoid breathing vapors.

Operation

Chitu Box Slicer Setup

1. Import .stl type file through Open File, and adjust the model by changing the view angle, size, and position of the model.
2. Go to "Settings" and Select ELEGOO MARS 2 PRO as the default printer.
3. Adjust the printer parameters as needed, though keep the parameters as default if no change is needed.
4. When the model is ready, click "Slice", and when it's done, click "Save" to export the sliced file and copy it to U disk. (Alternatively, selecting "Network Sending" immediately sends the print to the printer wirelessly.)

Recommended Parameters in Chitu Box

Resin Density: 1.1g/mL

Layer Height: 0.05mm

Bottom Layer Count: 3-6 layers

Exposure Time: 1.5-3s (Set according to the layer height and complexity of the model. Thicker layers require longer exposure times, resulting in lengthier prints).

Bottom Exposure Time: 20-40s (Longer exposure times create a stickier bottom on the build plate).

Light-off Delay/Bottom Light-off Delay: 7s/8s

Bottom Lift Distance: 5mm

Lifting Distance: 3-5mm

Bottom Lift Speed: 90mm/min

Lifting Speed: 100mm/min

Retract Speed: 150mm/min

Leveling the Bed

To level the bed, follow these steps:

1. Press "Tool" and the "Manual" on the touchscreen to enter the leveling interface.
2. Place an A4 sheet of paper on the LCD screen, ensuring both the screen and the build plate are clean.
3. Loosen the screws securing the build plate.
4. Tap the home icon to start the Z=0 process.
5. Once Z=0 is set, align the plate to avoid it touching the vat incorrectly.
6. Tighten the two screws to level the plate. There should be some resistance when pulling the paper. If there is no resistance, readjust the screws to level the plate. If there is too much resistance, lift the plate and reset Z=0 for this position.

Cleanup

Universal Cleaning Guide

• Return the equipment to neutral.
• Sweep up any dust and debris around the tool, your table top, and the floor - both in the equipment area and your work area.
• Clear the floor of any tripping hazards, like power cords.
• Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster behind the workshop.
• Leave the shop 110% better than you found it.

Tool Specific Cleaning Guide

• Do not use sharp or pointy tools to scrape the resin tank to avoid damaging the release liner film.
• Clean up the resin tank before changing the resin to another color.
• Before and after printing, clean the build plate with paper towels or alcohol to ensure that there are no bumps or burrs on the build plate.
• Before each printing, daily check the exterior of the machine and all mechanical parts for any obvious damage, defects, or abnormalities.
• Try to keep the printing environment at 25-30 degrees Celsius when printing, and ventilate the printing room as much as possible to facilitate heat dissipation of the machine and resin odor volatilization.
• If the Z-axis keeps making friction noise, add some lubricant to the lead screw. Please check and apply lubricant grease at least every 2-3 months, and increase the frequency of application as the printing frequency increases.
• If you don't use the printer in the next 48 hours, pour the remaining resin from the resin tank back into the resin bottle and seal it well. If there is any residue, please use a filter to filter it out.
• Check the condition of the release film before each printing, and observe whether the release film is loose, whether there are scratches or severe whitening on the surface, and if so, replace it in time. The release film is a vulnerable part, replace it at least once every 1-2 months, and increase the replacement frequency as the printing frequency increases.
• Be careful when removing the printing platform to prevent damaging the LCD screen. The service life of the screen is about 2000+ hours and will decrease with increasing printing frequency. Do a good job of daily screen cleaning, and unplug the machine in time after printing. If there is a screen exposure problem or service life has seriously affected the print quality, please replace the screen in time.
