Robotic additive manufacturing, also known as robotic additive manufacturing, is gaining popularity as a more flexible and efficient technique for 3D printing larger and faster objects.
Robotic 3D printing, also known as robotic arm printing, is a type of additive manufacturing that uses robots to create objects. A 3D printer head combines with a multi-axis robotic arm to make a 3D printer considerably more versatile than traditional three-axis devices.
With its wide range of motion, the robotic arm offers a whole new realm of creative flexibility in 3D printing. The arm can print from almost any angle, allowing the creation of very intricate curved shapes.
Printing parts with a robotic arm does not require supports with 3D printers, allowing greater design freedom and lower material costs. However, this requires self-supporting structures, which would normally rule out cantilevered designs. Many manufacturers, on the other hand, have addressed this problem by allowing the build deck to reorient, allowing for the creation of cantilevers.
Due to multi-axis toolpaths that can be designed with specialized 3D printing software, robotic 3D printing does not need to cut through layers like traditional printers.
This concept, however, brings us to the downsides of technology. Both the 3D printer head and robotic arm require programming instructions, making them difficult to use. There are no recognized standards for the transfer of information between the CAD system and the arm at this time.
Improper planning and control can cause poor printing or possibly the arm hitting the printed component and causing damage. The highest part quality is also influenced by the robot’s motion control systems, the quality and effectiveness of which can vary considerably.
Lastly, robotic 3D printers are often more expensive than conventional 3D printers. These factors have so far prevented them from becoming mainstream solutions, but as you can see from the printer options below, the technology is becoming more and more common.
The market isn’t exactly overflowing with hundreds of printer manufacturers, as you might expect given the specialized nature of robot-assisted 3D printing. Actually today you can buy a robotic arm from one company and an arm end extrusion tool from another.
Today, companies are more likely to build their own polymer or concrete boom end extruders and connect them to an “original” robotic arm. As a result, there are many more companies that provide robotic arm 3D printing services using their own printer than there are that sell robotic arm printers.
