What are the differences between the Elegoo Saturn & Saturn S?

Elegoo officially launched the Saturn on June 6, 2020. With initial supply issues, most people were only getting one after Q1 2021. After roughly a year on the market, Elegoo has already replaced it with a new version, the Elegoo Saturn S. The original Elegoo Saturn is available in the Liqcreate Lab. Due to the amount of machines currently released, we did not find the Saturn S interesting enough to add to our line-up of testing machines. In this article you can learn about the differences between the Elegoo Saturn and Saturn S.

Elegoo Saturn vs the Elegoo Saturn S

Towards the end of 2021, Elegoo released an upgraded version of the Elegoo Saturn 4K monochrome LCD resin printer. In this paragraph will a comparison of the main parameters of the Saturn S and Saturn can be found.

3D-printer Type	Elegoo Saturn S	Elegoo Saturn
LCD size	9.1”	8.9”
XY Resolution in pixels	4098*2560	3840*2400
Size of a pixel	48um / 0.048mm	50um / 0.05mm
LCD Screen Life	2000h	2000h
Build Volume	196*122*210mm (L*W*H)	192*120*200mm (L*W*H)
Printing Speed	30-70mm/h	30-40mm/h
Screen Scratch-resistant Film	√	√
Air Purifier	√	×
FEP film	FEP2.0	FEP1.0

Minimal improvements of the Saturn S compared to the original Elegoo Saturn:

• 1: Increase in LCD size from  from 8.9” to 9.1”.
  2: Increase Z-axis heigth from 200mm to 210mm
  3: Upgrade from FEP1.0 to FEP2.0, the release force is smaller, and the success rate of printing is improved.
  4: New air purifier, fresh printing environment

All the differences between the Elegoo Saturn and Saturn S are so small, that it is likely a supply-chain issue or cost-performance optimization that they “upgraded” this machine. From a performance standpoint the improvements do not seem to be big enough to launch a new version.

Elegoo Saturn & Saturn S compatible 3D-printing resin

Settings for all Liqcreate resins on the Elegoo Saturn are available on our website. As the Elegoo Saturn S is not available in our lab, we do not have validated settings for this 3D-printer. A good starting point would be the settings for the regular Elegoo Saturn, as these machines are quite similar.
