What reviewers found
Bambu Lab H2S
- CGMagazine (8/10): Called it refined and reliable. Real world print times were about 20 to 30% shorter than typical fast CoreXY profiles and aggregated XY error measured under 0.5 mm. Multi color prints ran a few hours longer than on the H2D on day long jobs, with considerable purge waste. Source
- The Gadgeteer: Ran the H2S AMS 2 Pro combo for about a month, often around the clock. First calibration took about 30 minutes, PETG CF prints finished well and the AMS 2 Pro was nearly error free. Downsides were purge waste on multi color jobs and the pricey optional Vision Encoder. Source
Prusa Research Original Prusa MK4S
- Tom's Hardware: Called it one of the best printers they have tested. Flow rose to 24 mm3/s with Prusament PLA, and a puzzle print took 2 h 59 min versus 3 h 23 min on a Bambu P1P with smoother parts that fit. Source
- TechRadar (5/5): Scored 30 of 30 in its print quality test with a combined dimensional error of 0.097 mm, and every Benchy in its multi print test finished. Noted the high price and open frame. Source
