3D Printed 7-Axis Robotic Arm
Dexter manufacturer Haddington Dynamics supplies its 7-axis fully assembled robotic arms and kits to NASA, GoogleX, and Toshiba. After using the arm, a high-profile customer suggested they move away from using weak PLA material and instead utilize Markforged’s Onyx material with continuous carbon fiber reinforcement to achieve the strength they desired. This was enough for Haddington Dynamics to purchase four Markforged printers. Inventor of Dexter, Kent Gilson said “within about three weeks of receiving our printers, we had completely redesigned the robot with the carbon fiber layup and saved all kinds of volume.” Dexter is now almost completely made from Markforged 3D printed parts, which has saved the company 58% in costs.
Haddington Dynamics’ customers receive custom swappable 3D printed gripper fingers with each robotic kit. Dexter’s modular end effectors are capable of pick and placing, gripping, 3D printing, and even working with CNC machines. A single Dexter pays off a printer. “You recover your ROI in a single output, which changes the manufacturing model,” said Todd Enerson, CEO at Haddington Dynamics.
