Robot Machining Will Complement Metal 3D Printing

When Peter Zelinski attended the recent International Manufacturing Technology Show (IMTS), part of what he was looking for were developments outside the show’s additive manufacturing area that have implications for AM. He found one in Kuka’s booth. The robot technology supplier showcased not only robotic 3D printing solutions, but also robotic metal cutting: using the robot CNC machining in metal. Improved robot rigidity makes this possible, along with a robot design allowing for high-force work. The promise: Metal 3D printing via robot can be performed in a hybrid cycle in which the robot itself also takes care of machining the part.

Pretty cool to conbine the process this way. I see this is a strong approach for prototype applications to lower cost and lead times for sure. Also add in the idea of low cost tooling design( practically non existent ), and i see this as a very strong application for low volume and fast lead time automation. Although this is niche, i am interested to see how the machine tool industry juggernauts continue to advance and pusg this forward. Imagine the ability to have real rigidity and spindle power at the helm of that flexibility. The future is here.

3D printing will never replace CNC machining completely. As you mentioned in the title, machining will be complementary to 3D printing. CNC machining can add a surface finish, tidy up the outside dimensions, drill holes, thread holes, machine some mounting pockets, and enhance overall features on the 3D printed part. Looking ahead, advancements in both technologies could lead to even more efficient workflows, particularly in industries like aerospace and medical devices, where precision and material properties are critical.

Well, why not add structure. Im looking into hybrid robots and i know that there are ways to continue to increase rigidity. Adding articulating arms similar to a parallel robot would be where I would develop further. A robotic arm alone wont replace a cnc mill. But you can add to it to make it just as good if not better at many applications.

Good. Fit it with a laser cutting/welding/marking head too for sheet + composites work.

If both a wire-arc print head and a milling tool could be mounted to the same robot arm you would have a very adaptable setup. Not as accurate as a dedicated CNC but much more portable for making parts in the field or in small spaces.
