Overall, the Ender 3 S1 Pro’s specs make it a superior machine next to the standard S1. The Sprite Extruder Pro, with its extra temperature headroom allowing the hot end to reach 300 °C, performed well through our tests and printed pretty much everything we threw at it that didn’t need an enclosure. The PEI-coated build plate also performed exceptionally, keeping standard materials in place with relative ease. Together, these two features are the best part of this machine.
