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 your printer. When operating the 3D printer, please wear a mask and gloves to avoid direct skin contact with the photopolymer resin. If the release lm in the resin tank is whitened, scratched, or has no elasticity, the printing failure rate is high, please replace the release lm in time. Please use 95% (or higher) ethyl alcohol or isopropyl alcohol to wash your model unless you are using water washable resin. If you have any problems with the printer, please contact us at 3dp@elegoo.com. Please do not disassemble or modify ELEGOO 3D printers by yourself, otherwise, the warranty will expire, and damage caused by personal operating errors need to pay for repairs.

Handle 1. Model Printing Slowly add the resin into the resin tank (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, and do not touch the machine during the self-check). 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, then lift the handle to take out the build plate, and use a scraper to remove the model. You can use ELEGOO's cleaning and curing machine to post-process the model. Software Installation and Setup The printer can install and use the Chitu Box in the USB ash drive. 1. Install Chitu Box Select from the USB ash drive or go to Chitu's ocial website (www.chitubox.com) to download the right slicing software version and install it on your computer. 2. How to Use Chitu Box After the installation is complete, run the Chitu Box software. Click "File-Open File", then open your 3D model le (.stl type). By left-clicking on the model and using the options on the left menu, you can control and change the viewing angle, size, and position of the model. 3. Chitu Box Setting 3.1 Machine Conguration Parameters Click "Parameter Settings" and select ELEGOO Saturn 4 Ultra as your default printer. (See Picture 1)

(Picture 1)

(Picture 2) 3.2 Build Volume You don't need to change the default parameters (See Picture 2), and X indicates the maximum print size in the X-axis direction, and so on. 3.3 Resin Parameter (See Picture 3) Resin Density: 1.1g/ml Resin Cost: You can input the real price of the resin you purchased, and the slicing software can calculate the resin costs for each model you print. Software Installation and Setup

(Picture 3) 3.4 Parameters (See Picture 3) Layer Height: The thickness of each printed layer, the recommended height is 0.05mm, but you can set it from 0.01-0.2mm. The higher the thickness you set, the longer the exposure time will be required for each layer. Bottom Layer Count: The setting number of initial printing layers. If the number of bottom layers is n, the exposure time of the rst n layers is the exposure time of the bottom layer. The default setting is 5 layers. Exposure Time: The exposure time for normal printing layers. The default exposure time is 2.5 seconds, and the thicker the printing layer setting is, the longer the time it will take. Bottom Exposure Time: The setting of bottom layer exposure time. Properly increasing the bottom exposure time can help to increase the stickiness between the printed model and the printing platform, and the default setting is 35 seconds. Transition Layer Count: The number of transition layers after the bottom layers for a tighter bonding between layers. Except for the exposure time, other parameters of the transition layers are the same as the normal layers. Transition Type: Set the transition type of exposure time when transitioning from bottom layers to normal layers, the default is linear transition. Rest Time Before Release: The time dierence between the end of print exposure and the start of printer release. The default is 0 seconds. Rest Time After Release: After the printing platform is lifted, the time dierence between the printer starts to rest and starts to return. The default is 0 seconds. Rest Time After Retract: The time dierence between the printer starts to rest after retraction and the start of exposure. The default is 0 seconds. Note: The printing parameters listed in this manual are for reference only. In actual applications, please contact the ocial after-sales technical support to conrm the parameters based on comprehensive factors such as the machine model and resin (including type and color) used by the individual. Network Management Center 1. After the printer is connected to WiFi, open the slicing software and click in the upper right corner to enter "Network Management Center" (You need to download and install Chitu Manager for rst time use.) (See Picture 4)

(Picture 4) Network Management Center 2. After entering the network management center, click "Add Device" to associate the printer

(make sure the computer and printer are in the same LAN), and the associated device can be remotely controlled through the computer. (See Picture 5)

(Picture 5) Network Management Center 3. In the printer management interface, you can turn on the camera to observe the printing situation in real time, and you can also control the time-lapse photography function to turn on or o. (See Picture 6)

(Picture 6) Machine Maintenance Please do not use sharp or pointy tools to scrape the resin tank to avoid damaging the release liner lm. Please 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, please 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, please 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 lter to lter it out. The release lm is a wearing part, please replace it regularly according to the machine prompts to ensure the success rate of printing. Please 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 aected the print quality, please replace the screen in time.
