The Full Review

The Bambu Lab P1S delivers professional-grade speed, reliability, and print quality in a well-engineered enclosed package that rivals printers twice its price.

The Bambu Lab P1S is a high-speed Core XY 3D printer designed for makers, hobbyists, and small businesses who want professional-grade results without the steep learning curve of traditional FDM machines. Building on the foundation of the popular P1P, the P1S adds a fully enclosed chassis with textured glass panels, improving thermal stability and making it far better suited for printing demanding engineering materials like ABS, ASA, and PC. Inside, the printer features a hardened steel nozzle, an all-metal hotend capable of reaching 300°C, and an active cooling system that helps parts cure evenly and quickly, letting the P1S output print speeds up to 500mm/s while maintaining impressive accuracy and surface finish. What sets the P1S apart in the 3D printing space is its blend of automation and convenience. The printer includes automatic bed leveling, flow calibration, and vibration compensation, all of which reduce the manual tuning typically required to get clean first layers and consistent extrusion. A built-in camera allows for remote monitoring and timelapse creation through the Bambu Handy app, while Wi-Fi connectivity and cloud slicing via Bambu Studio streamline the entire workflow from design to finished print. The optional AMS (Automatic Material System) turns the P1S into a multi-color, multi-material powerhouse, automatically switching between up to four spools mid-print without operator intervention, which opens the door to complex, colorful designs that would otherwise require manual filament swaps. Physically compact yet sturdy, the P1S offers a 256 x 256 x 256mm build volume, giving users ample room for functional parts, cosplay props, miniatures, and prototypes. Its enclosed design not only improves print quality on temperature-sensitive filaments but also reduces noise and contains fumes, making it a practical choice for shared workspaces or home offices. Paired with Bambu Lab's own PLA, PETG, and ABS filament lines—engineered for consistent diameter and moisture-resistant packaging—the P1S delivers a cohesive ecosystem where hardware and materials are optimized to work together. For anyone in the 3D printing and filament niche looking for speed, reliability, and minimal fuss, the P1S stands out as a machine that bridges the gap between hobbyist affordability and near-industrial performance.

The Bambu Lab P1S delivers professional-grade speed, reliability, and print quality in a well-engineered enclosed package that rivals printers twice its price. Its combination of fast CoreXYS motion, smart calibration, and optional AMS multi-color printing makes it an outstanding choice for hobbyists and small businesses alike, though newcomers should budget for accessories and expect a modest learning curve with its ecosystem.
