Elegoo Saturn vs Saturn S

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. The Elegoo Saturn is a reliable pick for a medium resin printer and so is the Saturn S, the new variant.

Since the 'upgrades' of the Saturn S are minor and the price is ~$50 higher, we would recommend sticking with the regular Elegoo Saturn. If you want a printer with more volume, check out the Photon M3 Series or the Saturn 2. If you want some extra XY-resolution and are on a budget, go for one of the smaller resin printers.

Going into 2023, it appears that the original 4K Saturn is being phased out.

Saturn S vs Saturn

Elegoo Saturn S

Saturn S and Saturn

  • Both printers have aluminum vats by default.
  • Antialiasing works on both printers and can be verified through UVTools.
  • The Saturn S and Saturn can be used with the Chitubox or Lychee slicers.
  • Both Saturns' LCD screens have a pre-installed tempered glass protector.

Saturn S

  • The Saturn S gains a ≈3.8% increase in the printing area - 192x120 to 196x122 mm.
  • There is an extra 10mm in build height over the regular Saturn.
  • The Saturn S has a slight bump in XY resolution, 0.002 mm - 0.05 mm to 0.048 mm.
  • The Saturn S replacement screens are not publicly available yet, so if you need one you will have to contact Elegoo.

Elegoo Saturn

  • The regular Saturn does not come with Elegoo's "air purifier", which is just a small brick of compressed carbon. This unit is inconsequential since carbon tends to only filter ~40-60% of VOCs (in a 1"+ thick layer). For a primary defense, resin printers should always be placed outside the residence or vented out a window.
  • The Elegoo Saturn comes with "FEP1.0" while the Saturn S comes with "FEP2.0". This, along with 'nFEP', is primarily just marketing. Very little difference exists between FEP and PFA - they can be obtained from the manufacturer, supply websites online, amazon, or from distributers like McMaster. The FEP from McMaster is actually US-sourced PFA & is a solid choice.
  • The light intensity of the Saturn is 2.07 mW/cm2 at the surface of the LCD screen.

Final Thoughts

As you can tell, the Saturn S and Saturn are essentially the same printer. It is hard to justify the added cost of the Saturn S with the minor upgrades. However, it appears that the Saturn is being phased out, so we are left with the Saturn S and Saturn 2.

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.
