Test Printing

After inserting the build plate into the connecting block, press down the handle to secure the build plate. The build plate is capable of self-leveling and ready to use.

1. Model Printing

Slowly add resin into the resin tank (ensure the resin level is not less than 1/3 of the tank volume and does not exceed the MAX line). The machine will perform a self-check before printing; do not touch the machine during this process. Cover the printer's anti-UV cover and then select the sliced test model for printing.

2. Model Processing

After printing is completed, wait until the resin on the build plate stops dripping. Lift the handle to take out the build plate, and use a scraper to remove the model. ELEGOO's cleaning and curing machine can be used for post-processing the model.

3.3 Resin Parameter

• Resin Density: 1.1g/ml
• Resin Cost: Input the actual price of the resin purchased; the slicing software can calculate the resin costs for each model printed.

3.4 Parameters

• Layer Height: The thickness of each printed layer. Recommended height is 0.05mm, adjustable from 0.01-0.2mm. Higher thickness requires longer exposure time per layer.
• Bottom Layer Count: The number of initial printing layers. The default is 5 layers.
• Exposure Time: Exposure time for normal printing layers. Default is 2.5 seconds. Thicker layers require longer exposure.
• Transition Layer Count: Number of transition layers after bottom layers for better bonding. Other parameters are the same as normal layers, except for exposure time.
• Bottom Exposure Time: Exposure time for bottom layers. Increasing this can improve stickiness to the printing platform. Default is 35 seconds.
• Wait After Cure: Time between end of exposure and build platform leaving surface. Default: 0 seconds.
• Wait Before Cure: Time between build platform moving to printing surface and starting exposure. Default: 0.5 seconds.
• Wait After Lift: Time between printing platform lifting, becoming stationary, and starting to return. Default: 0 seconds.
• Bottom Wait After Cure: Time between end of exposure and build platform moving away from surface for bottom layers. Default: 0 seconds.
• Bottom Wait Before Cure: Time between build platform moving to printing surface and starting exposure for bottom layers. Default: 0.5 seconds.
• Bottom Wait After Lift: Time between build platform lifting, becoming stationary, and starting to return for bottom layers. Default: 0 seconds.
• Bottom Lift Distance: Distance build platform leaves printing surface each time during bottom printing. Default: 3+4mm.
• Lifting Distance: Distance build platform leaves printing surface each time during normal layer printing. Default: 3+4mm.
• Bottom Retract Distance: Retract distance of the build platform during bottom printing. Do not change if not necessary.
• Retract Distance: Retract distance of the build platform during normal layer printing. Do not change if not necessary.
• Bottom Lift Speed: Moving speed of build platform away from printing surface during bottom printing. Default: 65+180mm/min.
• Lifting Speed: Moving speed of build platform away from printing surface during normal layer printing. Default: 60+180mm/min.
• Bottom Retract Speed: Moving speed of build platform close to printing surface during bottom printing. Default: 180+65mm/min.
• Retract Speed: Moving speed of build platform close to printing surface during normal layer printing. Default: 180+65mm/min.
• Parameter mode: Default is static mode. Options include high-speed mode or smooth mode. The printer dynamically adjusts parameters based on model complexity to improve print quality and speed.

Note: Printing parameters listed are for reference only. For actual applications, contact official after-sales technical support for confirmation based on factors like machine model and resin type/color.

FAQ

1. Model doesn't stick to the build plate

Bottom layer exposure time might be too short; please add more time. Ensure the model bottom has sufficient contact with the build plate and add more bottom layers.

2. Model layer breakage

Check if the printer is shaking during printing. The release liner film may be too loose due to long-time usage and needs changing. Ensure the build plate or resin tank is securely fastened.

3. Abnormal Screen Exposure

If your printer is not working correctly, contact ELEGOO at 3dp@elegoo.com. Please include your order ID in your email to help resolve the issue faster.

4. Printing failure

If a model was not completely printed or failed, there might be residues left in the resin. Filter the resin using a funnel when saving it back into its bottle. Failure to filter residues can damage the LCD screen on subsequent prints. Clean residual resin on the build plate and tank with tissues.

5. Error message for residue detection when starting a print

First, check if the resin tank and build plate are properly secured. Try printing again. Avoid touching or causing vibrations to the machine during the self-check process to prevent sensor calibration issues. If the error persists, clean the resin tank or filter the resin for any tiny foreign objects.

6. Resin insufficient or exceeding maximum volume error when starting a print

The mechanical sensor detects the remaining resin. Ensure the resin level is above one-third of the tank volume and does not exceed the MAX line to prevent leakage. If the required resin amount exceeds the current level, a prompt for resin refilling will appear. Recalibrate the device through the self-check process if abnormal errors occur. Do not touch or vibrate the machine during self-check.

7. How to adjust the printing speed

The release speed is fixed (fast/slow modes available). The first 50 layers are always printed at a slower speed for higher success rates. Actual printing speed per layer depends on slicing parameters like layer thickness, exposure time, and wait time.

8. Resin leaks into the machine

Due to the nature of tilted release motion, a completely sealed printing area is not possible. Protective measures are in place. When the sensor detects resin exceeding the MAX line, the print stops with a warning. A groove below the build plate collects minor leaks. For significant spills, disconnect power promptly and open the front panel for cleaning.

Machine Maintenance

• Do not use sharp or pointy tools to scrape the resin tank to avoid damaging the release liner film.
• Clean 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 there are no bumps or burrs.
• Before each printing, perform a daily check of the machine's exterior and all mechanical parts for obvious damage, defects, or abnormalities.
• Maintain the printing environment at 25-30 degrees Celsius and ventilate the room to facilitate heat dissipation and resin odor volatilization.
• If the Z-axis makes friction noise, add lubricant to the lead screw. Apply lubricant grease at least every 2-3 months, increasing frequency with printing usage.
• If the printer is not used for 48 hours, pour the remaining resin from the resin tank back into the resin bottle and seal it well. Filter any residue.
• The release film is a wearing part; replace it regularly according to machine prompts to ensure printing success.
• Be careful when removing the printing platform to avoid damaging the LCD screen. The screen's service life is approximately 2000+ hours, decreasing with increased printing frequency. Clean the screen daily and unplug the machine after printing. Replace the screen if there is an exposure problem or if its service life affects print quality.
