Sovol SV06 Plus review
A big-bed printer built on the open Prusa i3 MK3 design. Not fast, but fully open-source, well understood, and generous on build volume.
Best for: A big, open, hackable printer on a budget.

Specifications are the manufacturer's published figures. "Max speed" is a peak that no printer holds across a whole part, so use it for comparison and don't expect it in real print times.
