⚖️ Expert Verdict
The Bambu Lab P1S and the Original Prusa MK4S represent the two biggest names in the enthusiast market today. The P1S is a CoreXY machine that comes fully enclosed and ready for multi-colour printing with the AMS, focusing on a fast and automated user experience. The Prusa MK4S is an open-frame bed-slinger that focuses on extreme mechanical precision and long-term durability. Prusa’s 'Nextruder' and load cell sensor provide a perfect first layer without any calibration, which is slightly more consistent than the P1S’s system. However, the P1S being enclosed gives it a massive advantage for technical materials like ABS, which are difficult to print on the open MK4S without buying a separate enclosure. The P1S is also significantly faster in most real-world scenarios due to its CoreXY motion. Prusa wins on open-source repairability and long-term firmware updates, ensuring the printer stays current for years. If you want a printer that will last a decade and is easy to fix, get the Prusa. If you want a fast, enclosed, multi-colour machine that works like an appliance today, the P1S is our winner.
