Between these two large-format 3D printers, the real question is not which is objectively better; it is which print workflow you need. One is a used Elegoo Saturn MSLA resin printer with a $149.95 price tag and an explicit for parts/repair position. The other is an open box Creality K1 Max FDM printer at $590.00 built around high-speed printing and auto leveling. In industrial additive 3D printing, resin and FDM are different approaches to the same large-format goal, and that difference matters here more than the price spread.
Quick verdict
Choose the Elegoo Saturn if you are comfortable with a used MSLA printer that has only been power-on tested and is sold as-is for parts or repair. Choose the Creality K1 Max if you want a large-format FDM printer with 600 mm/s max speed, auto leveling, and monitoring features in an open box unit.

Where each product wins
Elegoo Saturn wins on entry price and resin detail
If your budget is the deciding factor and you are willing to treat the machine as a repair project, the Elegoo Saturn is the lower-cost large-format MSLA option. It also carries the layer-resolution detail of an MSLA resin printer, with a 28.5 µm pixel pitch and a 218.88 x 123.12 x 250 mm build envelope.
Creality K1 Max wins on speed and feature set
If speed and automation are the priority, the Creality K1 Max has the high-speed feature set: 600 mm/s max speed, auto leveling, LiDAR first-layer scanning, camera monitoring, and dual cooling. The 11.81 x 11.81 x 11.81 in build volume gives it a large-format FDM footprint.
Product notes
Elegoo Saturn Large-Format MSLA Resin 3D Printer
At $149.95, this is the lower-priced large-format resin option in the comparison, and the listed specs include a 218.88 x 123.12 x 250 mm maximum print size and 28.5 µm resolution. The important limitation is that the unit is used, intended for parts or repair, has only been power-on tested, and no accessories are provided unless otherwise stated. That means the buyer should expect to repair and configure the setup themselves. If you want a printer that is simply ready to print, this is not the option. But if you are looking for a lower-cost resin platform and have time to troubleshoot, it fits.
Creality K1 Max 3D Printer
The Creality K1 Max is the higher-priced option, but it also has the high-speed FDM focus. Listed as open box, it includes 600 mm/s max speed, 20,000 mm/s² acceleration, auto leveling, LiDAR first-layer scanning, real-time camera monitoring, and dual cooling. The 11.81 x 11.81 x 11.81 in print volume is generous for large-format work. The trade-off is the higher listed price and the open box condition, so this is not a brand-new sealed unit. For a shopper who wants a large-format FDM machine with speed and automation, this is the one.
Final choice by use case
For a shopper who wants a large-format MSLA resin printer and is ready to take on an as-is repair project, the Elegoo Saturn at $149.95 is the match. For a shopper who wants a high-speed large-format FDM printer with auto leveling and monitoring, the Creality K1 Max at $590.00 is the match. The two are separated by $440.05, but they are really solving two different problems: one is a low-cost resin repair project, the other is an open box high-speed FDM machine.
