New auto ejection tool for Bambu Lab print farms automatically ejects finished 3D prints from the machine — $129 kit includes auto door opener and special bed surface for frictionless part ejection

3DQue Systems wants to make 3D print farming easier and more hands-free. The company has developed both hardware and software, such as AutoFarm3D, to replace manual workflows. This includes auto ejection, where prints can be popped right off the bed by the printer itself, and also an automated door opening and closing mod that enables prints to be ejected from the machine before another print is started.

The concept isn’t new, and we’ve seen YouTubers in the past add a bit of g-code that makes the print head push a finished print off the bed. In 2021, 3DQue introduced Quinly3D for bedslingers, which added a toolhead shield, tilted platform and slide to the concept. The contraption allowed the print time to cool and loosen from the heated bed, then instructed the 3d printer to push the print forward. The tilted base lets gravity do the rest of the work.

However, Bambu Lab’s Core XY printers pose a unique problem: doors. You can’t just tilt a P1S – one of the most popular 3D printers used by print farms – and keep the door closed.

Enclosed printers are used to maintain a stable temperature for engineering-grade materials, so removing the door is not an option if you’re printing in something like ASA, Nylon, or a PC blend material. 3DQue created an automatic opener for these printers that attaches to the corner of the door and opens it on command.
