Resin-based 3D printers have been round for a number of years now and can be found in all sizes, starting from items sufficiently small to suit in your desktop to bigger printers which have a quantity that exceeds some standard FDM printers. As producers develop these printers, they’re quickly including new options to make them simpler to make use of and extra accessible to the typical individual and the brand new Saturn 2 isn’t any exception.
Elegoo has been within the resin 3D printer enterprise for the previous few years and has produced a number of totally different sizes starting from small printers just like the latest Elegoo Mars 3, which has a 4K decision, all the best way as much as the brand new Elegoo Jupiter, with a 6K decision. Just like the quantity in its title suggests, the brand new Elegoo Saturn 2 is the most recent iteration of their Elegoo Saturn line of resin 3D printers and comes with fairly a number of enhancements. The Saturn 2, which is designed to compete with the Finest Resin 3D Printers, usually has a retail value of $600, however will probably be out there for pre-order with an early hen value of solely $500 for the primary 1000 items and $550 for the following 5000 items.
For the prints on this evaluation, I used a few of Elegoo’s water washable resin as a result of it was thinner than the low odor resin I had used beforehand with different resin printers and I needed to deliver out the small print so the prints would come out higher. I used to be very impressed with the brand new resin and utilizing it did appear to make a distinction in each the benefit of cleanup in addition to an enchancment within the high quality of the prints.
In keeping with Elegoo, they need to have an 8K resin out there very quickly, nevertheless it was not out there for buy on the time of this evaluation.

Included within the Field with Elegoo Saturn 2 8K
The Elegoo Saturn 2 got here properly packaged with loads of foam round all sides together with some cardboard reinforcements alongside the sides to assist stop any injury occurring throughout delivery.
Like a lot of Elegoo’s different printers, it got here packaged in a nesting doll model with the instruments packaged within a smaller field. The smaller field is within the printer itself together with the construct platform, which is positioned inside a big block of froth.
The Elegoo Saturn 2 features a fairly normal array of equipment that many different Elegoo resin printers ship with together with instruments such because the diagonal cutters for help removing in addition to the metallic and plastic spatulas.
The metallic spatula is for serving to to take away your prints from the construct plate and also you need to watch out whereas doing so, as it may possibly probably gouge or scuff the metallic floor. The comfortable spatula is used extra as a software for cleanup akin to helping with eradicating any residual resin out of the resin tank when emptying.
It additionally comes with a set of hex key wrenches and a few spare screws in case any servicing or repairs must be carried out through the printer’s lifetime. There are two pairs of latex gloves and two surgical model masks for private safety, however you’ll in all probability need to get some greater high quality masks and extra gloves for working with resin.
Moreover, it comes with a set of paper filtering funnels, the facility brick, an air air purifier module, a consumer guide, and a USB reminiscence stick to a duplicate of the guide, Chitubox Fundamental (the beneficial slider for the Elegoo Saturn 2) and a few check prints on it.
Design of Elegoo Saturn 2 8K
Instantly, you possibly can inform the design of the Saturn 2 is totally different from the earlier fashions. Whereas not being as curvy because the Mars 3, the aesthetic is interesting in its personal proper. With regard to the options, the Elegoo Saturn 2 is closest in design to the Saturn S of another of Elegoo’s choices, which is to be anticipated as that was the earlier mannequin.
One of the apparent enhancements of the Elegoo Saturn 2 is the 8K excessive decision display screen. The display screen is 10 inches, which is a noticeable enchancment over the 8.9-inch display screen on the unique Saturn and the 9.1 inch show that got here on the Saturn S.
Along with having a bigger display screen, additionally it is a considerably greater decision then both of its two predecessors. The upper decision means you possibly can produce extra detailed fashions than ever earlier than. Beneath the 8K LCD is a Fresnel Lens that is ready to distribute the UV mild very evenly.
The Elegoo Saturn 2 is pushed by a pair of linear rails together with a pleasant thick lead screw for a really sturdy construct platform, which is important to supply detailed prints at such a excessive decision.
One of many extra fascinating design options is a detachable panel within the rear of the UV cowl that can be utilized to connect with an exhaust air flow system to assist additional cut back odors for individuals who function in small areas and are involved with fumes.
Like Elegoo’s Saturn S and Jupiter printers, the Saturn 2 8K comes with a replaceable air air purifier module that’s powered by a port beneath the UV cowl. Despite the fact that the port is formed like a normal USB port, it has a warning subsequent to it that the output voltage is 24 volts as an alternative of the same old 5 volts produced by USB ports, so that you wouldn’t need to plug your USB reminiscence stick into it. Throughout testing, I seen that there was nonetheless a lingering resin odor that wasn’t utterly eradicated.
One other function that I’m actually glad to see on this mannequin is that the facility swap that’s on the rear of the Saturn S has now been changed with an influence button on the entrance of the Saturn 2, making it very handy to activate and off.
Leveling the Construct Platform on the Elegoo Saturn 2 8K
Leveling the printer was fairly simple. Step one is to loosen the 2 bolts on the perimeters of the resin tank. Then utilizing the management panel on the entrance of the printer, you need to increase the construct platform to a ample peak that the resin tank will be eliminated.
Then after ensuring the big knob that holds the construct platform onto the printer is tightened, use the biggest hex key to loosen the bolts on the entrance and aspect slightly below the knob. Ensure that to take away the display screen protector from the LCD should you haven’t already.
There’s a card that comes with the printer that’s concerning the thickness of cardstock. It would be best to place that straight on prime of the LCD display screen. On the sooner generations of printers, a daily piece of paper was used to compensate for the thickness of the FEP movie, however a thicker card is now used as a result of the brand new FEP 2.0 movie is thicker and extra sturdy.
Subsequent, you’ll want to press the house button to decrease the construct platform till it rests squarely on the cardboard. You possibly can press the house button to readjust the cardboard if vital. As soon as you’re pleased with the place, maintain the construct platform with some strain in opposition to the LCD when you tighten first the entrance bolt, after which the aspect bolt.
You possibly can then press the up button till the construct platform is excessive sufficient to reinstall the resin tank. The platform ought to now be correctly leveled. If you’re having bother with prints sticking to the platform otherwise you discover a flat spot in your printed mannequin after eradicating it, chances are you’ll need to attempt re-leveling the platform.
Printing Security with Elegoo Saturn 2 8K
With resin printing, you’ll want to print in a properly ventilated space that’s nonetheless out of the best way of any UV radiation akin to direct or oblique daylight. Even with the low odor resins, the fumes can nonetheless be poisonous. Additionally, you will need to be sure to are sporting gloves to keep away from straight contacting the resin together with your pores and skin.
One factor that you simply hear mentioned a bit much less typically is publicity to UV mild. With the Elegoo Saturn 2, I examined whether or not eradicating the quilt would flip off the UV mild supply and sadly discovered it continues to emit UV mild. Though it’s probably not any stronger than daylight, it’s best to keep away from wanting straight at a UV mild supply together with your eyes should you will help it, and it’s a good suggestion to keep away from direct publicity to your pores and skin as properly. More often than not the resin will probably be masking up the UV mild supply, so this isn’t actually a lot of a problem, however it’s one thing to concentrate on.
Printing Included Take a look at Prints on the Elegoo Saturn 2 8K
Take a look at prints enable 3D printer producers to reveal the printer’s strengths. Having the prints pre-sliced is a little bit of a double-edged sword. On one hand, the producer can select the perfect settings for the printer, however however, the producer is making a guess concerning the particular resin that new customers will probably be utilizing to supply the check prints. In typical Elegoo vogue, the check print that comes with the Saturn 2 is a pair of rooks.
With a few of Elegoo’s earlier printers, this guessing has yielded softer prints that had been typically gouged with the spatula upon removing. It seems that the corporate has elevated the publicity time with the most recent check prints, so it takes a bit longer, however the mannequin is much less prone to be broken.
Printing the check prints is fairly easy. Simply insert the USB reminiscence stick into the USB port on the fitting aspect of the printer, choose the Print possibility from the primary menu, open the “ELEGOO SATURN 2 Rook Mannequin for Printing Take a look at” folder, and choose the Rook Take a look at Print Mannequin. There may be additionally an STL of the mannequin if you need to attempt slicing it your self with Chitubox.
Making ready Recordsdata for Printing with Chitubox
The very first thing you’ll need to do after you have Chitubox Fundamental put in is so as to add a brand new printer within the software program. The present model on the time of this writing already has the Saturn 2 as an possibility, making setup a breeze. One factor you’ll want to verify is the publicity instances on the resin you may be utilizing. I ended up needing to extend the publicity time fairly a bit for the water washable resin as a result of the default values left the resin somewhat too comfortable.
After you might have your printer all arrange, you possibly can load a mannequin to slice. Slicing with a resin printer is sort of a bit totally different from slicing for a standard FDM printer. For the reason that mannequin is printed the other way up and is printed used liquid resin, there are further issues you should take into consideration akin to drainage holes, the load of the merchandise you’re printing so it doesn’t fall off the construct plate, and even the place the helps connect in order that when they’re eliminated, you don’t take away delicate particulars.
For the primary mannequin, I went with the Tower of Pi to point out primary slicing. This one is pretty simple because it doesn’t have any massive strong sections, nevertheless it additionally has plenty of element making it a terrific demonstration of a resin printer.
To get your mannequin ready, you’ll want to place the mannequin at an angle. Putting fashions at an angle makes it a lot simpler to take away them from the construct platform with out injury within the course of. It additionally offers extra floor space for helps to carry on so the mannequin is much less prone to fall throughout printing.
Begin by opening up the file that you simply wish to print. You possibly can open the Rotate panel on the left aspect by clicking the Rotate button. In case your mannequin is just not upright, you possibly can first get it oriented accurately utilizing the controls. As soon as it’s upright, discover the axis that corresponds to the longer aspect of the construct platform and click on +45° or -45° to position it at a forty five diploma tilt with the intention to add helps. You possibly can at all times regulate this angle to your liking, however I discovered the lean buttons had been fairly handy.
Beneath the Helps tab on the fitting aspect of the display screen, you possibly can have Chitubox robotically generate helps. For this mannequin, I discovered the default settings to be ample and added helps just for objects above the construct platform by clicking on the +Platform button. After urgent the button, it is going to take about 10 seconds or so for the helps to be generated.
As soon as the construct helps are in place, you possibly can return to the Settings tab and click on on the Slice button. It will slice the mannequin. As soon as it’s sliced, a Save button will seem, which is able to can help you save the sliced file onto the USB stick that got here with the printer.
As soon as it’s saved, you possibly can eject the reminiscence stick out of your laptop and plug it into the printer. On the printer, simply go to the Print possibility from the menu and select the mannequin. It ought to present up simply because it seemed in Chitubox.
Printing a Bust on the Elegoo Saturn 2 8K
To check printing a bust, I made a decision to go along with a mannequin of an Elf Archer Bust as a result of the scale match properly on this printer and I needed to see how the small print got here out. Chitubox has a pleasant function that permits you to hole out the mannequin. It additionally has a function to can help you add drain holes with the intention to rinse out any extra resin from inside the pinnacle.
To begin with, I loaded my mannequin into Chitubox Professional simply as described above and obtained it sitting at an angled orientation. I oriented with the face pointing away from the construct platform in order that there can be fewer helps on the face.
I clicked on the Scale button to get to the size controls and elevated the size to the utmost utilizing the Scale to suit button. Then I backed it off by about 10% in an effort to depart room for the helps.
I clicked on the Hole button on the prime, which lets you set the thickness of the outer shell. I elevated the worth to 3mm as a result of the defaults are a bit on the skinny aspect. I then added a single massive drainage gap on the underside of the bust utilizing the Dig Gap software.
The opening will largely aid you out when washing and cleansing your mannequin as most extra resin will depart the mannequin as it’s printed. Chitubox may even robotically generate a plug that you need to use to fill the outlet after washing, although chances are you’ll select to only delete this.
After this, it’s only a matter of producing helps like with the primary mannequin and printing it out.
After you have completed printing, you possibly can wash the within of the mannequin out utilizing the drain gap. I seen that helps had been generated contained in the mannequin by means of the outlet, however I simply left them. Whereas cleansing my print, I used to be somewhat too keen with eradicating the helps and ended up breaking the hair and chipping the face, however in any other case the standard of the print turned out excellent.
Printing Detailed Fashions on the Elegoo Saturn 2 8K
For an in depth check print, I went with a mannequin known as Purple Dragon that includes a winged dragon. This mannequin was somewhat too massive for this printer on the full measurement, so I selected Scale to suit, which got here out to round 75% or the unique measurement. I didn’t hassle to hole the within as many of the bigger options weren’t excessively large and because of this, no drainage holes had been vital. The principle factor to be careful for on an in depth mannequin like that is guaranteeing the helps are in a spot the place eradicating them doesn’t trigger you to by accident injury the print.
Washing and Curing on the Elegoo Saturn 2 8K
After printing, the mannequin will nonetheless probably have some leftover resin on it and, to get a resin print to look its greatest, you’ll want to clear it.
To clean the fashions, I used Elegoo’s largest Wash and Remedy station, the Mercury X bundle. Though this was designed with the unique Saturn and Saturn S in thoughts, which have barely smaller construct volumes, I discovered the construct platform nonetheless match into the tank. The one concern I had was with a few of the taller prints bottoming out.
As a result of I used a water washable resin, I emptied the isopropyl alcohol from the rinse tank right into a bucket to be used at a later time and changed it with faucet water.
What labored properly for me was to start out off by washing the merchandise within the water first after printing, then take away the helps whereas they had been nonetheless comfortable. After that, I dipped it in water briefly and used the comb included with the water washable resin to loosen up any extra resin residue. I gave it one other rinse within the rinse tank in hopes that the water would now be capable to get into the nooks to assist take away any further resin. After letting the merchandise utterly dry, I then cured it and this prevented any white residue from forming on the prints, which may occur even with the water washable resins.
Cleansing Up After a Failed Print on Elegoo Saturn 2 8K
Prints can and ultimately do fail even on resin printers, although I didn’t expertise any failed prints on the Saturn 2 myself. Whether or not it occurs on account of help constructions which might be unable to help the mass or any variety of different issues, you continue to could have a large number to wash up earlier than you possibly can print once more.
It’s best to start out by eradicating the mannequin above the resin tank. I discovered that utilizing the metallic spatula on the construct plate labored fairly properly. The rationale you need to take away the mannequin first is to keep away from dripping any resin onto the LCD display screen, which could be very tough, if not unattainable to take away as soon as hardened.
After that, run a tank clear cycle by means of the printer’s menu, which is able to expose your complete backside layer of the tray to UV mild and create a strong mass of any little items which will have damaged off of the failed print. You could think about including a chunk of eliminated help from a earlier print to at least one nook first to make removing of the mass simpler.
As soon as that’s full and you’ve got eliminated the hardened resin, it is best to empty the resin tank. The plastic spatula works properly to help with this. Emptying the resin first permits you to examine the FEP movie as properly. If it will get too broken, chances are you’ll want to interchange it earlier than persevering with.
Additionally, you will need to confirm that any stray resin didn’t get on the surface of the resin tray in order that it doesn’t find yourself getting onto the LCD display screen when positioned again onto the printer, which may find yourself curing there. Despite the fact that the LCD is scratch resistant, you’ll nonetheless need to be extraordinarily cautious should you did have any resin remedy there, which is why it’s best to keep away from it within the first place.
You need to use some isopropyl alcohol to assist clear any surfaces that resin will get onto and paper towels to wipe it dry. You could need to depart any failed prints outdoors to dry within the solar and harden or you might place them in a remedy chamber should you like.
This can be a very polished machine that produces prints of phenomenal high quality. Throughout your complete time I used to be testing it, I had no failed prints. If you’re in search of a mid-sized 3D resin printer or you should print in a excessive degree of element, you actually can’t go incorrect with this printer.
One other printer that’s in the same price range vary that you could be additionally need to check out is the Phrozen Sonic Mini 8k with an much more spectacular decision of twenty-two microns, however with the tradeoff being a smaller print quantity. In order for you one thing with a smaller footprint and you want Elegoo, chances are you’ll think about going with the Elegoo Mars 3. If you’re in search of a bigger construct quantity, chances are you’ll need to think about looking on the Elegoo Jupiter. Nevertheless, if you would like this degree of element and construct quantity collectively, the Saturn 2 8K is difficult to beat.
