Flexoflow 3D Printer: Flexible arm structure

grabcad

The Flexoflow 3D printer is a single-part, flexible geometry model inspired by Dr. Shridhar Kota's work at the University of Michigan and NASA's flexible wing aircraft. It features an arm operated by three motors that twist a "guiding plate" to move the nozzle/machining head for material deposition. Gear and worm wheel torque transmission maintains structure position while preventing backward torque. A rotatory base provides access to the third degree of printing, and the printer's leafy structure reduces weight and power requirements, as well as maintenance needs. Flexoflow's flexible geometry distributes stress uniformly for increased durability and can be manufactured using additive methods in one step. Inspired by a tree branch's flexibility during wind, the designer created several paper models before finalizing this innovative design.
