Elegoo Saturn Review: Is This the Best Printer For You?

It’s incredible how 3D printers have come a long way from as recently as five years ago. Back then, when you say 3D printer, people would think of a costly machine that would take too long to print something. And they wouldn’t be right.

But things have changed. You now have 3D printers that are speedy and can be within budget. But even when they’re affordable, there are no apparent tradeoffs. You still get a quality machine that can deliver eye-catching prints in high resolution.

The Elegoo Saturn is one of these devices. Using masked stereolithography technology, the Elegoo Saturn can deliver speedy print times with decent resolutions. It’s also a printer that offers a big build volume at a price that you would love.

What are the features of the Elegoo Saturn that you should know? And should you buy it? Read on and discover more about this 3D printer.

Monochrome LCD

Elegoo Saturn

If you only need to read one section, then this should be it. Elegoo Saturn is a masked stereolithography 3D printer.

Stereolithography traces its meaning to two Greek words:

  • Stereo, which means solid
  • Lithography, which means writing

Your stereolithography printers are creating objects using light. Probably the best-known types of stereolithography use laser and digital light processing.

  • Laser-based stereolithography uses an ultraviolet laser to create your prints. These lasers are reflected onto the print area, and the light solidifies the resin on a layer per layer basis.
  • DLP stereolithography, on the other hand, projects light onto the resin.
  • Masked stereolithography replaces the laser and projector with an LCD screen.

Benefits of Masked Stereolithography

Masked stereolithography prints your objects faster than a laser SLA printer, especially when you’re printing denser and larger items. What’s more, because these LCD panels are the same ones used for smartphones, availability is not an issue.

They are mass-produced, so LCD panels in these 3D printers cost less too.

Elegoo Saturn Is Faster than Most Other MSLA Printers

If MSLA printers, in general, are faster than laser stereolithography printers. That is because of the technology that allows the printer to print an entire layer of your object as opposed to the piece by piece printing done by lasers.

But because the typical MSLA uses the same LCDs as your smartphones, these colored LCDs have filters to deliver red, green, and blue to your screen. These filters are blocking some of the light that would typically go straight to the resin and cure it.

So when it comes to MSLA printers, monochrome LCDs are not a bad thing. It just means a printer can print your objects a lot faster than most MSLA printers.

And true enough, the Elegoo Saturn has a printing speed of 1.2 inches (30 millimeters) per hour. The monochrome LCD significantly reduces the curing times of the resin because it has a more intense light.

High-Resolution LCD

Not only is the Elegoo Saturn fast, but prints are impressive as well. The 4K screen measures 8.9 inches (226.06 millimeters) with a 3,840 by 2,400 pixels resolution. That is four times the number of pixels compared to 2K screens.

However, because of the huge build size of Elegoo Saturn, its overall X/Y pixel size rests at 50 microns, which is slightly less detailed than the X/Y pixel size of both Mars Pro and Mars.

Design

The Elegoo Saturn’s design draws comparison to the company’s own Mars and Mars Pro printer: Saturn looks the same as Mars and Mars Pro, only bigger.

Saturn’s base measures 11 by 9.4 inches (280 by 240 millimeters) with an all-metal build. It puts the control panel at the front. This touch display measures 3.5 inches (88.9 millimeters), and it is how you interact with the printer.

The USB slot of this printer is located on the right side, fortunately making it more accessible than the USB slot on the Mars that Elegoo put at the back of the machine.

The vat where you put the resin is also larger than the one on Mars and Mars Pro, measuring 7.6 by 4.7 inches (192 by 120 millimeters). Putting in or changing the resin is now easier and less messy because of the pouring aid.

Z-Axis

You will surely be impressed with the Elegoo Saturn’s Z-axis. The lead screw is sandwiched between two linear rails, making it very stable and sturdy.

Notable Features

Elegoo Saturn 3d printer

So what are the features that you should know about the Elegoo Saturn?

  • The 4K monochrome LCD delivers a more intense light source for faster curing times. This LCD panel is much bigger and more durable than the ones you find on Mars and Mars Pro.
  • Dual linear rails provide more stability to the printer.
  • A print resolution of 50 microns means that this printer can deliver bigger prints with the same level of detail as the Elegoo Mars.
  • Two cooling fans help to keep the temperatures low while also helping to make the LCD last longer.
  • The touch display is big enough at 3.5 inches (88.9 millimeters), allowing you to operate the device efficiently.
  • Ethernet connectivity is a technology that allows you to print from your computer and even remotely.
  • The prints will adhere better to the bed because of the sandblasted surface. That means that you’d have less printing errors.

Resin

Elegoo Saturn works with a wide variety of resins. What’s more, the company manufactures and sells its own resins, but you can use third-party products with this printer.

Pricing

With all the nifty features, a sizable print volume, fast printing times, and other attractive benefits, you’d expect to pay a lot for the chance to own an Elegoo Saturn.

However, this printer retails anywhere from $300 to $600, depending on where you look. It is sold on Amazon, as well as other online retailers. But it is always out of stock.

Huge Build Volume

We’ve saved the best for last. What can make an affordable and fast 3D printer even better? A significant build volume, of course.

In this regard, the Elegoo Saturn doesn’t disappoint. It has a build volume of 7.6 by 4.7 by 7.9 inches (192 by 120 by 200 millimeters). These dimensions significantly beat out the Elegoo Mars: Saturn has 3.5 times the print volume of the Elegoo Mars.

Bottom Line

We certainly wish that all companies, no matter what their product is, would be like Elegoo. They have taken an excellent product in the Elegoo Mars and made it better, faster, and bigger.

The company has not disappointed its users with the release of both Elegoo Mars and Mars Pro, and they didn’t start disappointing with the Saturn. With a massive build volume and faster printing times, while keeping the price down and the print resolutions the same, Elegoo has made Saturn the go-to 3D printer for people who like the have professional quality prints without spending too much.

Pros

  • Works really fast and efficiently
  • Breezy and headache-free operations right out of the box
  • Compatible with 405 nm UV-sensitive resins

Cons

Comparison to other Elegoo 3D the printers

We’ve compared the Saturn with Elegoo’s earlier printers: Mars and Mars Pro. It is easy to see just how the company has improved its offerings over time. The Saturn is bigger and faster than both of its older siblings and yet delivers the same print resolutions as the smaller printers.

Here’s a side-by-side comparison of these three printers to make it easier for you to see how the Saturn compares to earlier devices from the same company.

FAQs

Question: What is the big deal with bigger build volumes anyway?

Answer: A lot of 3D printing enthusiasts will tell you to get a printer with a significant build volume. There are many benefits to owning one.

You get to print the 3D model in its entirety. A big build volume allows you to print your models in one piece, rather than printing it in parts and then assembling them afterward.

Not only does printing and assembling more parts take time, but it also costs more. What’s more, if you have to work with a smaller printer, you will lose details in the 3D model because you are forced to scale everything down.

When you have a bigger build volume, you can have more pieces when you print in batches. For instance, you can easily print ten small 3D models with a printer that has a massive build volume as opposed to only three to five in smaller printers.

In effect, you save a lot of time and resources with a bigger build volume because you no longer have to do a lot of batches.

Question: What are the benefits of MSLA printers?

Answer: We have touched on how MSLA printers cost less and print faster than other types of stereolithography printers. But there are more benefits to owning an MSLA printer like the Elegoo Saturn:

  • It can produce more accurate parts, as well as include more details than other types of 3D printers.
  • It has a smooth finish, so you can create stunning prototypes without spending a lot of time post-processing.
  • There are many specialty resins available not just for MSLA printers but also for other types of SLA printers. You can get castable and flexible resins if you need them.
  • There are some interesting things that you should know about SLA printers, as well. These are what you might call the downsides of owning one:
  • SLA printed parts are less durable than those printed with other types of 3D printers, such as those that use fused deposition modeling technology. As such, if you are printing functional parts, it is best to avoid doing so with an SLA printer.
  • SLA prints are vulnerable to sunlight. As such, these parts will change, deteriorate, and degrade over time.
  • When printing with an SLA printer, you typically need strong supports. This process might add to post-processing time and work.

Should You Buy the Elegoo Saturn?

When it comes to affordable 3D printers, the Elegoo Saturn ticks a lot of boxes. Aside from the attractive price, you also get a printer that has a massive build volume, allowing you to get prints that measure 282 cubic inches (4,624 cubic centimeters).

It uses one of the newest technologies, MSLA, with a monochrome LCD that allows it to cure resins in two seconds and print up to slightly more than an inch (30 millimeters) per hour.

So while the Elegoo Saturn can be hefty and heavy, it’s really a difficult printer to pass up. However, it’s not always available and can be out of stock at several retailers, including the company’s own online store. Fortunately, there are alternatives that you can find.

If you want something with a bigger build volume, you can go for the Peopoly Phenom. This printer can give you a build volume of 1,043.9 cubic inches (17,106.3 cubic centimeters) and almost twice the maximum height. But you might be turned off by the price, which is more than six times that of Elegoo Saturn at $2,000.

If you’re working within a smaller budget, both the Phrozen Sonic Mini and the Photon Mono SE are closer to the Elegoo Saturn when it comes to pricing. Both of these printers use monochrome LCD and can deliver fast printing times. But both have smaller build volumes than what’s offered by Elegoo Saturn.

The Final Word on the Elegoo Saturn

The Elegoo Saturn is one of those 3D printers that gives you what you want: fast printing times, huge build volumes, and 4K clear printing resolutions. It also helps that the manufacturer doesn’t scrimp on the materials, giving you a sturdy, durable, and stable printer. Plus, it will not cost the buyer an arm and a leg to own this device.

It’s hard to go wrong with such a 3D printer, and we don’t have problems recommending it at all, if only Elegoo manufactured more of them, as it’s almost always out of stock.
