2. Case Studies & Real-World Applications

3. Case Study -1 Bambu Lab AI Mini – IoT-powered 3D printer .

4. Motion system of the A1 mini Accelerometers : These sensors are installed on the tool head to monitor the tension force of the X-axis and Y-axis belts. Eddy Current Sensor : Located in the hot-end, this high-resolution, high-frequency sensor measures nozzle pressure. It enables active flow rate compensation by dynamically adjusting the extrusion based on real-time pressure reading These sensors work together to ensure precise movement and extrusion, contributing to the A1 Mini's high-speed and high-quality 3D printing capabilities.

5. Tool head module The tool head unit is one of the key components of the A1 mini. The tool head module mainly consists of the following components: hot-end assembly, extruder unit, cutter unit, filament hub, and filament sensor.

6. Tool head module This allows the toolhead to accommodate four different materials, enabling multi-color printing combined with a multi-color printing module . In addition, the filament hub contains a magnet inside, which works in conjunction with a filament entanglement hall sensor to check for filament entanglement . When there is excessive resistance during filament feeding, the filament hub is pulled down, causing the magnet to move closer to the Hall sensor and triggering a filament entanglement alert.

7. Cooling System Efficient cooling of the printed model is essential for fast printing . The A1 mini has a custom 5015 centrifugal fan, featuring two opposing air outlets. This design directs the cooling air precisely towards the vicinity of the nozzle, ensuring rapid cooling of the printed parts.

8. Touch Probe Detection A1 mini has a feature to measure the force exerted on the hotend , which can be used to detect contact between the toolhead and the heatbed . Combining this with the up-and-down movement of the Z-axis, the A1 mini can directly measure the height of a specific point on the heated bed relative to the center of the bed

9. Camera The printer integrates a camera used for spaghetti detection (to be supported in future firmware updates) and real-time monitoring of prints using the Bambu Slicer or Bambu Handy application. In addition to the monitoring function, the camera can record videos of the prints to the micro SD card and generate time-lapse videos. The machine is not equipped with night vision, but the camera module has an auxiliary light to illuminate the print.
