The limitation of 3D Printer build volume is over. The folks over at NEXT and LIFE Labs have created a prototype robot with a 3D print head attached to it. Unlike a traditional 3D Printer that moves the print head around within the confines of a machine, the 3&DBot drives the print head around any flat surface, extruding as it goes.
Although the 3&DBot has 4 wheels, they are all stationary and face independent directions. Normally, this arrangement would only allow a vehicle to rotate in a circle. However, the wheels used here are not conventional, they are Mecanum-style with many mini-wheels around the main. This arrangement allows omnidirectional movement of the robot, depending on how each wheel is driven. If you haven’t seen this type of movement before, it is definitely worth watching the video after the break.
Sure, the print quality leaves something to be desired and the distance the print head is from the robot chassis may be a bit limiting but all new technology has to start somewhere. This is a great joining of two technologies. Don’t scoff, remember your Iphone 12 wouldn’t be possible without this.
