3D Printed 7-Axis Robotic Arm
Haddington Dynamics, an engineering startup who develops and manufactures a 7-axis robotic arm for such customers as NASA, GoogleX and Toshiba, spent years trying laser cutters and inexpensive desktop printers to build a robot without success.
When they discovered Markforged 3D printing, it allowed them to achieve just what they were seeking — engineering-quality parts for their robots. They were so impressed that they built their business around 3D printing and created a print farm of carbon fiber printers to keep up with demand.
From end-use parts to custom end effectors, read on to see how they reduced part counts from 800 to less than 100 to save time and money.
Robotic arms need to be cost-effective and stiff enough to maintain 50-micron precision in the arm’s movements.
A fleet of several Markforged printers allowed the team to develop durable custom gripper fingers for customers.
Haddington Dynamics reduced part count from 800 to under 70 and can assemble Dexter robots within a day.
