Bambu Lab A1 Combo with upgraded heatbed Features Full-Auto Calibration and Auto Bed Level Goodbye to Tedious Manual Calibration And Tuning A1 handles various calibrations all by itself. It meticulously calibrates the Z-offset, bed-level, vibration resonance and nozzle pressure for EVERY print job, automatically. Auto Z-Offset No More "Paper Method" A1 probes the bed with the nozzle to measure the absolute Z-offset. No need to stick a paper as reference. Auto Vibration Calibration Auto Tune Both X & Y Resonance Before Every Print A1 has sensors in toolhead and heatbed. One of the very first bed-slinger printers to run auto resonance calibration on both X & Y axes. Auto Flow Dynamics Fully Automated PA (Pressure Advanced) Calibration First of its kind, A1 runs the nozzle pressure based flow dynamics calibration algorithm. No need to draw any pattern or get any manual pick & match involved, A1 handles Pressure Advanced calibration automatically. Auto Belt Tension Auto Monitoring And Adjusting The Belts A1 can check the belt tension automatically through the vibration frequency calibration. If the belt tension is loose the HMS system will notify you to adjust the auto belt tensioner. Auto Filament Loading Load/Unload Filament With One Touch No manual setting involved, A1 fully automated the filament load/unload process. Swift Maintenance Quick Swap Nozzles All-new quick swap hotend design, the hotend pops in and out with just 1 clip. AMS lite Multi-Color Printing For Everyone The all-new AMS lite is elegant and reliable, making multi-color 3D printing accessible to everyone. Active Flow Rate Compensation Print Smooth At Every Corner, Always The A1 revolutionizes flow control in 3D printing. It utilizes a high-resolution, high-frequency eddy current sensor to measure the pressure in the nozzle. Our algorithm actively compensates the flow rate according to the readings to extrude with accuracy. High-speed Precision Bed Slinger with CoreXY Speed And Quality Full-metal Rails, Rigid frame, nozzle pressure sensor, accelerometers, powerful MCU, and above all, an advanced motion control system that utilizes these features to print a 14-minute benchy with quality and following all the speed benchy rules straight out of the box without using specialized filaments. Intuitive UI As Easy As Your Smart Phone A1 now has a simplified touchscreen UI system that walks you through all the hurdles. You don't have to be a 3D printing expert to use the A1.
