Bambu Lab A1, brand new and unused. This is the A1 Combo without the AMS Lite multi-material printing system. Therefore, the box has been opened once. Since it is unused, I believe there will be no operational issues, but returns are possible if there are initial defects. Nozzle replacement is easy and requires no tools. It is equipped with a camera and can take time-lapse videos. You can print and check the image during printing remotely from your smartphone or PC. Product Description Fully Automatic Calibration No effort required The A1 automatically handles various calibrations. It performs high-precision calibration for all print tasks, including Z-offset, bed leveling, resonance, and nozzle pressure. Fast and High Precision Reliable high-speed performance The A1 is equipped with low-drag linear rails, a powerful MCU, an acceleration sensor, a nozzle pressure sensor, and an advanced motion control system that maximizes their potential. Its high-speed performance is built on a solid foundation, ensuring consistent reliability with stable and uniform output in all prints. Full-size build volume Ample space to expand your imagination The A1 has a build volume of 256mm x 256mm x 256mm, which is larger than most entry-level printers. You can print a helmet in one go.
