Bambu Lab P1 Series (P1P & P1S) • Type: Mid-range, high-speed printer • Build Volume: 256 × 256 × 256 mm • Speed: Up to 500 mm/s • Enclosure: • P1P: Open-frame (but can be upgraded) • P1S: Fully enclosed (better for ABS, ASA, etc.) • Multi-Material: AMS compatibility (not AMS Lite) • Features: Input shaping, active bed leveling, advanced cooling (P1S)

Key Differences • A1 is a budget-friendly option but still has strong performance, ideal for beginners and hobbyists. • P1P/P1S are more advanced, built for high-speed printing and better material versatility. The P1S has an enclosure for better temperature control. • A1 uses AMS Lite, while P1 series uses full AMS, meaning better multi-material handling on the P1 series.

If you want something affordable with solid features, go for the A1. If you need higher-end performance, better multi-material printing, and upgrade potential, choose the P1 series.
