Original Prusa MK4S is built around our new 32-bit connected architecture and the next-generation extruder (Nextruder). It lays down a perfect first layer every time without Live Adjust Z and it has support for high-speed printing with Input Shaper and Pressure Advance. We also improved the safety features even further. Plus, there are a ton of useful things, such as quick-swap nozzles, built-in support for remote printing and webcams, and many more. And it’s still beautifully quiet.
