Prusa Research was founded as a one-man startup in 2012 by Josef Prusa, a Czech hobbyist, maker and inventor - and now one of the most famous names in the 3D printing industry.

What's a Clone? It's important to note that, while printers like the Ender 3, being ultimately inspired by the Original Prusa i3, are technically clones, they also sort of exist in their own categories now.

Both the Ender 3 S1 Pro and the Prusa MK3S+ come standard with auto bed leveling, but they use differing methods to achieve the same results. The S1 Pro uses a CR-Touch probe, which uses a moving probe to detect the position of the bed, while the MK3S+ uses a superPINDA inductive sensor.
