Reliability revision
MK3S+ introduced SuperPINDA, revised Y-bearing clips, a reinforced X-end and smaller filament-path changes. Prusa describes this as a reliability and assembly revision rather than a large print-quality change.
First layer and connectivity
Mesh bed leveling is automatic, but first-layer Z adjustment remains manual. Network control needs an additional Raspberry Pi; it is not native Ethernet or Wi-Fi hardware.
Introduced in 2020.
Announced November 24, 2020; Prusa said shipping began the previous week.

Read this with the specifications

A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
