3D Farmers has introduced an interesting free 3D model for automation for the Bambu Lab A1 and A1 Mini 3D printers. The focus is on a modular setup that automatically removes components and thus significantly reduces the manual workload per printing process. The basis for this is a combination of mechanical conversion and software optimization, which is tailored to precisely designed STL models and G-code macros.
The system is based on a 20-degree tilt module for the A1, which is attached without tools using existing threaded holes. This tilt facilitates the automatic removal of finished printed parts. The parts are removed using a scraper coated with TPU to prevent scratches on the components. An adapted design of the printed objects reduces the contact surface and favors the peeling movement during removal.
According to 3D Farmers, automation reduces the unit cost of a component from around $7 to $2.70. While initial tests still had to contend with mechanical problems during removal, stable results were achieved through slicer hacks and design adjustments. The 3D model and further details can be downloaded directly from MakerWorld. The A1 mini model can be found here.
