The Maker’s Toolbox: Elegoo Jupiter 2 Resin 3D Printer Review

Sometimes you want both detail and size, which is why Elegoo launched the original Jupiter MSLA (masked stereolithography) resin 3D printer back in 2021. It had a large build volume, but still offered the detail and quality of resin printing. It is, however, now pretty old and MSLA has come a long way since then, which is why Elegoo just released the new and improved Jupiter 2.

I’ve been testing the new Elegoo Jupiter 2 for the past couple of months and am ready to tell you about my experience with the printer.

The basics

The Jupiter 2 has a lot of improvements over the original Jupiter, starting with resolution. The original Jupiter had a 6K screen, which was very good at the time, but that was across the large 12.8” panel that was necessary to achieve the generous build volume. The result was a pixel size of 51×51µm. That number represents the “raw” detail the printer can achieve and was pretty average at the time.

The Jupiter 2 is much, much better. It has 16K resolution in the same 12.8” screen real estate, resulting in a pixel size of 20×26µm. So, the pixels on the Jupiter 2 are just 1/5th of the area of those on the original Jupiter. In theory, that allows for much finer detail — though there is a point of diminishing returns, because resin curing doesn’t scale down infinitely.

The build volume of the new Jupiter 2 is 302.4×162×300mm, which is a bitlarger than the original Jupiter, but not dramatically so. It is 24.6mm wider, but only 6.0mm deeper. It is, however, gargantuan by typical MSLA resin 3D printer standards.

Aside from the much better screen, most of the practical differences are about convenience and resin handling. The new Jupiter 2 can pump resin in and out of the vat, can heat the resin in the vat, has a larger touchscreen interface, handy hinged doors, a built-in camera, auto-leveling, a quick-release build plate, and a more sophisticated sensor suite.

Unboxing and first impressions

The Elegoo Jupiter 2 is huge and it comes in a huge box. You may need a friend just to help you move the thing and get it onto your workbench.

The printer comes packaged well, but mine did arrive with some very minor damage to the bottom of the door area. That was probably the shipping carrier’s fault, but it is still worth noting. Thankfully, it doesn’t affect the functionality and you wouldn’t even see it if I didn’t tell you about it.

Setup time is about average for a modern MSLA resin 3D printer. You’ll spend most of that time taking parts out of the box and peeling off protective film. The resin pump setup takes a bit of time, but Elegoo helpfully provides some large jugs for you to use with any resin you already have on hand.

When you turn on the Jupiter 2, it will go through a basic configuration wizard and then perform a self-test. That self-testing happens every time you power up the printer, but it only takes a minute or so to complete.

Once you’ve added resin (more on that in a moment), you can print a pre-sliced test file or use Elegoo SatelLite software to run your own job. If you configure WiFi, SatelLite can send sliced files to the Jupiter 2 over your network, so you don’t have to fiddle with USB thumb drives.

Resin feeding

This was the feature I was most excited about, because dealing with resin is a big hassle — and most of the reason I usually stick to filament these days.

On the back of the Jupiter 2, there is a mounted holder for rectangular jugs of resin (the typical cylindrical bottles don’t fit). A hose goes from that bottle to an internal pump, which can run in both directions. In one direction, it pumps resin into the vat to keep the level optimal through large prints. In the other direction (recycling mode), it pumps resin from the vat back into the bottle.

Automatic resin filling is nice, because you don’t have to worry about the vat going dry if you print something particularly big. A flip-down sensor tells the Jupiter 2 when resin is at the right level.

The “recycling” mode is nice, because you don’t have to deal with the mess and hassle of trying to pour resin from the vat back into the bottle. That’s particularly useful if you like to switch between different resin colors or types.

However, the recycling mode doesn’t do a good job of sucking all of the resin out of the vat. You’ll need to tilt the printer back so the resin pools around the hose, or use a scraper to push the excess resin into that area. Even then, there will be some left in the vat that you’ll need to wipe up.

It is also worth noting that some resin will stay in the hose, so you’ll get slight contamination when switching from one kind of resin to another. It is minimal enough that it shouldn’t be a problem in most cases, but it is worth considering if you’re switching from, say, black to white.

The build plate

The Elegoo Jupiter 2, like most other resin printers these days, has a quick-release latch for the build plate. That’s nice and works well, so removing the build plate only takes a second.

However, the build plate itself is pretty standard and that’s kind of a shame. Some other manufacturers have started using build plate designs that allow for print removal without tools. The Halot X1, for example, has a two-piece build plate that releases the print with just a little wiggle.

I was disappointed to see that the Jupiter 2 doesn’t incorporate something like that, because removing resin prints from build plates is always a pain (often a literal pain, when you stab yourself with the scraper).

I don’t want to knock the Jupiter 2 too hard for this, because most resin printers still have these standard rigid build plates. But it is worth taking into account.

The doors

I really like the dual doors on the Jupiter 2. They swing out of the way, giving you plenty of space to work. You don’t have to fumble around with a big cover that needs a dedicated place to rest. And because the doors swing out horizontally, you can put the Jupiter 2 on a shelf with limited vertical space.

The doors are the kind of convenience feature that I love to see on new printer models. They won’t generate hype, but they make actually using the printer a lot more pleasant.

The heated vat

There isn’t much to say here, except that the Jupiter 2 has a heated vat and that is a good thing. The resin in the vat will naturally heat during the printing process and that temperature change can affect quality. By heating the resin before printing and maintaining that temperature during printing, you avoid issues.

Frankly, all resin printers should have vat heaters these days.

Sensors galore

The Elegoo Jupiter 2 has a whole bunch of sensors and it goes through a self-check procedure every time it starts up.

In my testing, that always worked fine.

There is always a chance of a sensor failing, and so increasing a printer’s complexity isn’t always a good thing. But because mine didn’t have any problems, I don’t have anything negative to say about the sensor suite. Presumably, some (like the load cells used for leveling) improve quality and/or reliability, so that is a bonus.

The user interface

The user interface on the Jupiter 2 is mostly fine. The touchscreen is a good size, has nice image quality, and is responsive. And finding your way around when printing isn’t too difficult, as there isn’t a whole lot to figure out.

But there were some things I didn’t like, including the menu structure. That resin recycling function, for example, is buried under the Settings > Accessibility menu. Why is it there? I have no idea and it doesn’t make sense. I’m sure some users won’t even realize the function exists, because they wouldn’t think to look there.

That isn’t a big deal, but I recommend looking through all of the menus to learn which functions are available and where they are.

Software

As of April 20th, 2026, Elegoo says that the Jupiter 2 “is currently only compatible with ELEGOO SatelLite, but this will be updated later.”

So, I used SatelLite for all of my testing. Based on its functions and overall design, I’m pretty sure it is just a re-skinned Chitubox. The performance is certainly similar.

I don’t love it, because a lot of things are just weird. To change resin parameters, for instance, you have to go to Home > Personal Library and create a new entry in your library (or edit an existing one). You can either create that from scratch or modify an entry, including one you import from the cloud. It is convoluted and sometimes didn’t seem to update properly for me.

Those quirks aside, SatelLite is functional and does the core tasks — adding supports, hollowing, resizing, and slicing — just fine. The automatic supports are surprisingly good and offer tons of customization, though I wouldn’t put it quite on the same level as Lychee.

Test Prints

My test prints all turned out great.

If you’ll allow me a digression, my opinion is that we’re past the point of diminishing returns and have reached the physical limits of MSLA resin printing.

Screens can reach higher pixel density and light engines can certainly get more parallel. But UV curing is a chemical reaction and it is hard to confine it to an area any smaller than we already do.

All of that to say that the Elegoo Jupiter 2 has fantastic print quality, but the same has been true for pretty much all decent MSLA resin printers for years.

There isn’t anything at all to complain about on the quality front, it is just that there isn’t anything special about the print quality either.

I think if you’re buying a Jupiter 2, it is for the build volume and other features, like the automatic resin filling and the vat heating.

Conclusions

The Elegoo Jupiter 2 is a solid printer. It is big, works well, has a decent feature set, and doesn’t have any serious problems. The question is: how does it compare to the competition and should you buy it?

I think there is actually a very strong case for the Jupiter 2, because competing printers lack either its build volume or its resolution. The Anycubic Photon Mono M7 Max, for example, has a similar build volume, but about half the resolution in each axis (X and Y).

In fact, there really aren’t any viable competitors that match the Elegoo Jupiter 2’s build volume and resolution right now. That will probably change in the near future, but the Jupiter 2 is the only consumer MSLA 3D printer with that particular combination right now.

At a price of $899, it is very compelling. I wouldn’t say it is perfect, but its issues are minor and it sure seems to be the best option available to those who want big prints at high resolution.
