Firstly, let’s take a look at what this printer does well. It absolutely hits some peaks for me, and on these, alone, it’s a worthwhile contender to many printers on the market.
Extruder and nozzle
The S1 Pro also has a "Sprite" full-metal dual-gear direct extruder rather than the more common Bowden design (where the filament is fed through a plastic tube at an angle). With an extrusion force of 80N. This is a manual loading and unloading process, but it allows for a bit more wiggle room when it comes to which filaments you use, and is generally very straight forward.
The S1’s new brass nozzle design can stand up to 300°C printing temperature, and is compatible with multiple filaments, such as PLA, ABS, PVA, Wood, TPU, PETG, and PA.
The build plate is magnetic PEI Spring Steel, which is pretty common these days because of how easy it is to remove prints from the surface—no more worrying about scratching your build plate with a chisel as you try to pry the plastic off.
A feature I enjoyed having added from the get-go was the LED light, built into the top of the frame. Yes, you can mod your own onto the Ender, but it’s a lovely touch to have it there from the beginning.
The Ender 3 S1 Pro has a filament sensor to ensure that you don’t suddenly run out of filament and ruin a print, and includes a power loss detection feature, which likewise keeps a sudden outage from making a mess of things. These are totally standard at this price range these days, but weren’t not that long ago, so it’s worth a highlight.
You can use it to shoot lasers
One of the immediate highlights about the Ender 3 S1 Pro is that it’s compatible with Creality’s line of laser modules, opening an exciting doorway to a truly multipurpose device capable of both 3D printing and laser engraving.
