In the field of 3D printing, there is a continuous trend towards the automation of work processes. A new project by developer Andre Me aims to automate the changing of build plates on the Bambu A1 Mini 3D printer.
The system developed by Andre Me is based on a clever mechanism. Each build plate is fitted with a special device that interacts with attachments on the printer. This interaction enables the automatic loading of new plates and the removal of finished prints.
Once a printing process is complete, a customised G-code triggers an action: An attachment on the printer slides under the build plate and lifts it off the magnetic print surface. The finished plate is then pushed forwards. Behind the printer is a stack of fresh build plates, from which the printer removes a new one from below as required.
One of the main advantages of this system is the low number of moving parts. This increases reliability and reduces potential sources of error. However, the design takes up more space than the printer alone, which could be problematic in cramped environments.
Andre Me’s approach differs from other automation solutions, which often rely on ejecting finished parts. Instead, his system exchanges complete build plates, which can be particularly advantageous in series production.
The developer demonstrates the efficiency of his system in a time-lapse video.
Another video shows the system producing shells in different colours.
Such automation solutions could make 3D printing more attractive for small and medium-sized production series. They enable continuous operation with minimal manual intervention, which increases efficiency and reduces labour costs.
