A1 mini

The A1 mini is an FDM 3D printer from Bambu Lab with a 180 x 180 x 180 mm build volume.

Specifications

Build Volume: The A1 mini has a build volume of 180 x 180 x 180 mm .

Kinematics: It utilizes a Cartesian cantilever design (commonly known as a bedslinger), meaning it features a single Z-axis upright that supports the X-axis extruder arm, while the print bed moves along the Y-axis . To ensure stability, the printer uses full-metal linear rails across its axes .

Speed: The printer reaches a maximum toolhead speed of 500 mm/s and a maximum acceleration of 10,000 mm/s² [3, 10, 11]. Typical, consistent print speeds average around 200 mm/s to 300 mm/s .

Calibration

First-Layer Calibration

• Step: Thoroughly wash the build plate with warm water and detergent to remove dust or oils, and avoid touching the surface with bare hands . Ensure the nozzle is free of clogs and that the hotend screws are properly tightened . Print a simple 0.2mm thick cube scaled to the size of the bed to test the layer visually [3, 4].
• Expected outcome: A smooth, uniform surface where lines fuse without gaps, ridges, or peeling at the edges [4, 5].
