ELEGOO Saturn 2 8K 3D Printer, MSLA UV Resin Printer with 10 inch Monochrome LCD, Air Purifier and Screen Protector, 219x123x250mm Larger Printing Size
About this deal
Before any version could be put into production, work on all Saturn variants was stopped in favor of launching all future payloads from the Space Shuttle. Finally, FabFilter Saturn 2 contains all the usual FabFilter goodies: perfectly tuned knobs, MIDI Learn, Smart For this study, the Boeing company also investigated configurations designated INT-20 and INT-21 which employed its S-IC first stage, and eliminated either North American's S-II second stage, or the Douglas S-IVB third stage. Budget constraints led to cancellation of the study and exclusive use of the Space Shuttle for orbital payloads.
After you have your printer all set up, you can load a model to slice. Slicing with a resin printer is quite a bit different from slicing for a traditional FDM printer. Since the model is printed upside down and is printed used liquid resin, there are additional things you need to take into account such as drainage holes, the weight of the item you are printing so it doesn’t fall off the build plate, and even where the supports attach so that when they are removed, you don’t remove delicate details. After this, it’s just a matter of generating supports like with the first model and printing it out.
The Saturn INT-19 would have used smaller solid boosters, derived from the first stage of the Minuteman missile, to supplement the thrust of the S-II. Eleven configurations were studied, using between four and twelve solids, with some being started at lift-off, and some being started in flight, and varying propellant loads in the Saturn stages. The S-II stage would have been modified by refitting the J-2–SL engines with reduced expansion ratio nozzles, to increase sea level thrust to 174,400 pounds-force (776kN) per engine. The highest total impulse configuration would have used twelve boosters, with eight started at launch and four started after the first group had been jettisoned. It would have been capable of lofting a payload of 75,400 pounds (34,200kg). 
The popular Elegoo Saturn gets another new edition: the Elegoo Saturn 2! The successor is equipped with a huge 10-inch 8K monochrome LCD, allowing for even larger and more accurate prints. The huge build volume of this MSLA-3D printer makes it possible to print detailed, large-format objects. The Saturn 2 is equipped with dual linear rails along the Z-axis, which ensure high stability. The movements of the build platform run smoothly. The MSLA 3D printer allows you a Z-axis resolution of up to 0.00125 mm. This is a very polished machine that produces prints of phenomenal quality. During the entire time I was testing it, I had no failed prints. If you are looking for a mid-sized 3D resin printer or you need to print in a high level of detail, you really can’t go wrong with this printer.One thing that you hear discussed a bit less often is exposure to UV light. With the Elegoo Saturn 2, I tested whether removing the cover would turn off the UV light source and unfortunately found it continues to emit UV light. Although it’s likely not any stronger than sunlight, it is best to avoid looking directly at a UV light source with your eyes if you can help it, and it is a good idea to avoid direct exposure to your skin as well. Most of the time the resin will be covering up the UV light source, so this isn’t really much of an issue, but it is something to be aware of. Printing Included Test Prints on the Elegoo Saturn 2 8K To get your model prepared, you will want to place the model at an angle. Placing models at an angle makes it much easier to remove them from the build platform without damage in the process. It also gives more surface area for supports to hold on so the model is less likely to fall during printing.
