3D Robots Come Out of Printers Like Magic, No Assembly Required

A team of scientists in Scotland have successfully printed a soft-bodied robot from an upside-down block that can step out of the printer without further assembly.

The four-legged robot developed by the University of Edinburgh can be 3D printed in just 9 hours, significantly shortening the time compared to similar products in the US. (Photo: University of Edinburgh)

The device is made from the open source Flex Printer, which costs only about $500, much cheaper than commercial systems. (Photo: University of Edinburgh)

The printing material is flexible TPU plastic, which is often difficult to control because it easily bends and sags when melted. (Photo: RTE)

To solve the problem, the team reversed the printing process, instead of printing from top to bottom, they printed from bottom to top. (Photo: ENTECH Online)

This “upside down” approach allows gravity to better support the adhesion of the material layers, increasing precision and stability. (Photo: Tom's Hardware)

Once printing is complete, the tray is flipped over so the robot “stands” in the right direction, ready to go with its integrated pneumatic actuator. (Photo: IFLScience)

Although it is only a demonstration prototype, this technology promises to open an era of cheap, accessible 3D printing of soft-bodied robots. (Photo: MSN)

The team believes that 3D printed robots without assembly will soon be applied in exploration, medicine and emergency rescue. (Photo: ScienceDirect.com)
