What reviewers found
Prusa Research CORE One+ INDX
- TechRadar (5/5): Gave it Editor's Choice. In a head to head with the Bambu Lab H2C, the INDX produced 27 models while the H2C produced 15. Scored 27/30 on its print test suite with 0.208 mm average X and Y error. Downsides: slow recalibration and soft nozzles. Source
- Tom's Hardware: Editor's Choice. A PLA dragon took 25 h 41 min with 1,646 tool changes and 18 g of waste; a PETG planter took 6 h 14 min with 6.84 g of waste. It made 83.58 g less waste than the Bambu Lab H2C on the same job. TPU prints oozed and jammed. 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
