The H2D is a large, heated chamber printer whose two nozzles cut purge waste in two material prints, and it can add a laser and cutter. It fits serious makers and small businesses that print engineering filaments or want one machine for printing and crafting. Skip it if you mostly print PLA at home, since it costs $1,549 or more and weighs 31 kg.

The MK4S is a proven open frame Prusa that prints very cleanly, runs quietly and can be bought as a kit for $709. It suits people who value print quality, repairability and support over the lowest price. Skip it if you want ABS without buying an enclosure or want multi color in the box.

What reviewers found
Bambu Lab H2D
- Tom's Hardware (Editor's Choice): Called it one of the best printers they had seen. A two color print of 114 parts took 8 h 4 min with about 2.6 g of purge and prime tower waste, versus 6.54 g on a P1P. A Benchy took 21 min 30 s. Source
- TechRadar (4.5/5): Scored 28 of 30 in both print tests. A two filament print took 5 h 27 min versus over 12 hours on an X1C. Noted a small laser work area and an AI camera that can pause prints too readily. 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
