What reviewers found
Elegoo Neptune 4 Max
- Tom's Hardware: Speed Benchy took 31 min 12 s. A 250% articulated frog took 10 h 26 min with rough spots and a near layer shift. A TPU purse printed well at 45 mm/s. About twice as fast as the Neptune 3 Max. Source
- 3DWithUs (4.5 out of 5): Assembly took about 30 minutes. Printed a 520 mm window handle and eight PETG brackets in one batch. The screen failed out of the box and needed a manual fix. ABS warped. Source
Prusa Research CORE One+ INDX
- 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
- 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
