I have been using this for work for about a year now. I no longer need it as I have stopped printing, so I will sell it. If it doesn't sell even with about 10 likes, I will put it up for auction. The contents are as follows: Saturn 3 Ultra main unit FEP film x 4 sheets (only 1 missing) ELEGOO ABS-like 3.0 resin 2kg (new) AC cables Universal wrench I wiped it down overall, but the dirt is noticeable, so I would appreciate it if you could purchase it with that in mind. There are no problems with the operation. Also, the USB ports on both sides of the main unit where the filters are inserted are likely unusable due to dust. It is more effective to use a commercially available charcoal odor eliminator or an air purifier than to attach a filter. Please also understand that some non-genuine parts, such as screws and tape, are used. I usually wrote print files to a USB memory stick without using Wi-Fi or other transfer methods. When printing by dynamically reading from the memory, the printing stops if you touch the memory even a little, so it is convenient to write it to the main unit in advance. The exposure test results of the panel are also shown in the image. I will take care not to scratch the panel, etc., when packing. I was using it until just a few days ago, so calibration is not necessary, and you should be able to use it immediately. I can be flexible with the price. It is also possible to sell the main unit only without accessories, and a discount is available for that. I also have another unit of the same model, a 16L ultrasonic cleaner, and a post-curing machine, so please let me know if you are considering these as well. If necessary, I can also provide the optimal parameters for the included resin (slicing settings).
