“Desktop 3D printer” means any machine that runs on a household outlet and fits on a bench, which in 2026 is everything from a 180 mm Bambu A1 mini to a 350 mm Creality K2 Plus, plus resin printers. The useful distinctions inside the category are size class, frame type (bedslinger, CoreXY, resin) and whether it is enclosed. Pick the size from your parts, the frame from your speed and material needs, and the process from whether you need detail or strength.
