⚖️ Expert Verdict
The Bambu Lab P1P and the Elegoo Neptune 4 Pro represent two very different ways to achieve high-speed printing. The Neptune 4 Pro uses Klipper firmware on a traditional bed-slinger design, offering incredible speed for a very low price. The P1P uses a more advanced CoreXY design which provides better print quality at those same high speeds. Elegoo’s machine is perfect for users who enjoy tweaking their settings and want the most 'bang for their buck.' On the other hand, the P1P is a premium product that focuses on a seamless, Apple-like user experience. The P1P is also compatible with the AMS system for multi-colour printing, which the Neptune cannot offer. While the Neptune 4 Pro is a fantastic value, it requires more manual leveling and maintenance over time. For a serious hobbyist who wants to focus on designing rather than fixing the printer, the P1P is the better long-term choice.
