Elegoo Saturn S vs Saturn 2

Last Updated: February 28th, 2023

Medium resin printers are ideal for those that need that bit of extra printing volume. The printers function exactly the same as the smaller ones and they have a similar level of reliability.

We recommend going with the Saturn S to save money, unless you absolutely need the additional build volume or resolution of the Saturn 2.

If you desire the resolution bump but are on a budget, then going with a printer like the Photon Mono 4K, Photon M3, or Mars 3 could be more applicable.

Saturn S vs Saturn 2

Elegoo Saturn 2

Saturn S and Saturn 2

  • Both printers have aluminum vats by default.
  • Both printers use PFA (nFEP/FEP 2.0) in the vat.
  • Antialiasing works on both printers and can be verified through UVTools.
  • The Saturn S and Saturn 2 can be used with the Chitubox or Lychee slicers.
  • Both Saturns' LCD screens have a pre-installed tempered glass protector.
  • Both printers come with Elegoo's "air purifier", which is just a small brick of compressed carbon. This unit is inconsequential since carbon will only filter ~40-60% of VOCs (in a 1-2" thick layer). For a primary defense, resin printers should always be placed outside the residence or vented out a window.

Saturn S

  • The Saturn S gains a ≈3.8% increase in the printing area and an extra 10mm in build height over the original Saturn. Also, there is the small bump in XY resolution - 0.05mm to 0.048mm.
  • The Saturn S is ~$200 cheaper than the Saturn 2.

Final Thoughts

As you can tell, the Saturn S and Saturn 2 are pretty similar. The main difference between the two is the XY-resolution increase by the Saturn 2. It also gains a fair amount of build volume but not enough to launch it out of the medium range.

The resolution and build volume increases of the Saturn 2 does not justify the extra ~$200 for casual users. The Saturn S is will provide the best bang for your buck.

Resin Printer Setup Example

Beyond the printer, you will need to budget for resin and additional supplies. Ideally, the printer will be outside the residence (ie: garage/shed/balcony) but it can be indoors in a separate room if vented out a window.

A grow tent is an affordable enclosure that can both assist in venting the printer and helping to keep the resin warm during winter. Small heaters and a temperature controller can be used to keep the resin at its recommended level.
