The best 3D printing solutions for robotic arms

One of the trends we increasingly see as additive manufacturing becomes industrialized is an increased focus on large format additive manufacturing. While this can of course be achieved with large machines, especially those using FDM, robotic arms offer a number of advantages for users. Robotic arms not only allow large-scale printing thanks to the long reach of the arms, but also more freedom thanks to their multiple axes as well as the fact that the resulting parts often do not require support structures. Although there are only a handful of manufacturers creating the robotic arms, they have been adapted by 3D printing manufacturers for polymer and metal AM solutions. In the following list, in no particular order, we take a closer look at what is currently on the market, both for original weapons and for adapted solutions.

Original Robotic Weapon Manufacturers

KUKKA

The German company KUKA is undoubtedly one of the leaders in the automation market, offering robots that allow the electronics, automotive and healthcare industries to simplify their manufacturing processes. KUKA develops solutions adaptable to additive manufacturing. It is therefore not surprising to find the KUKA brand on many robotic 3D printers, whether to design metal, plastic or even concrete parts. One example is the KR QUANTEC range of robotic arms, which offer machines with reach from 2,671 to 3,904 mm and load capacity from 120 to 300 kilos.

Third-party 3D printing companies using these solutions

CEAD

CEAD is a Dutch company based in Delf that develops large-scale 3D printers. This company stands out by offering robotic solutions that combine printing and CNC milling processes in a single process. Another solution is the AM Flexbot, a robotic solution for large-scale 3D printing. Siemens Sinumerik controllers are responsible for controlling the Comau robot arm, thus requiring no robot controller. This controller can control 31 axes at the same time as it moves along its path. Your AM Flexbot can be expanded with additional functions such as a rotary table, additional robots or other production processes such as CNC milling. It is the perfect choice for a custom solution with a specific application.

Weber Additive DXR Series

The German company Weber Additive, dedicated to the development of different manufacturing technologies, also offers robotic arm solutions for 3D printing. Weber’s DXR robotic system includes a high-quality extruder capable of 3D printing. The extruder is powered by a 6-axis industrial robot that allows it to move with precision. Its robotic arm based on the manufacturer Kuka and its AE series extruders are adapted to the needs of its customers to provide the most optimal results. These systems offer great advantages, such as 3D printing with 6-axis kinematics, variable angle of the build head or overprinting on existing parts, among others. You can take a look at the solution in the video below:

Hyperion Robotics’ robotic arm

Founded in 2019 in Helsinki, Hyperion Robotics is a company specializing in construction. He uses additive manufacturing to design more affordable structures, wanting to make the market more sustainable and above all, more automated. To do this, it relies on KUKA robots on which it mounts an extruder capable of depositing Hyperion Robotics material. It is a special concrete mix that uses a reduced amount of cement thanks to recycled waste components. He has also designed his own software that allows him to work with any robot. In terms of applications, the Finnish company has already built decorative elements, structures imitating coral reefs and energy infrastructures.

branch technology

This company combines additive manufacturing, prefabrication and large-scale digital technology. Thanks to their patented technology, it allows the team of designers and architects to imagine, compose and finally build these structures that were previously impossible with traditional construction methods. An example of a project they have done is building a 3D printed pavilion in which they used KUKA robotic technology. Combining robots with 3D printing allowed the architects and designers of the Gould Turnes Group they collaborated with to tackle not only the construction of the final structure, but also the design process from start to finish. The 3D printing process applied to KUKA robots is a great combination as it enables the production of precise, lightweight and economical components from a variety of materials.
