What reviewers found
Bambu Lab A2L
- Tom's Hardware: Editor's Choice. A Flexi panda took 2 h 40 min in one color and 6 h 46 min in three colors. A TPU 95A bag printed in 7 h 9 min. A PETG spinner failed near 95% due to a thin base. The AMS Lite vibrated off an IKEA Lack table after 45 minutes. Source
- FauxHammer (4/5): Called it a great hobby printer with good print quality for its class, but found the live camera feed about 1 frame per second and no ABS or ASA profile at test time. Source
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
