AIM3D Expands Applications of Universal Pellet Extruders in 3D Printing

The company AIM3D has introduced new developments in 3D pellet extrusion. With the launch of universally applicable screw extruders for third-party providers, the application spectrum of additive manufacturing is expanding. The universal pellet extruders can be used in large-format 3D printing systems as well as in process combinations with CNC or robotic systems. Additionally, they are suitable for coating, joining, and deposition processes.

Since 2017, AIM3D has been focusing on pellet extrusion technology, which differs from conventional FDM printing methods by processing cost-effective granulates instead of filaments. The company’s CEM extruders are known for their versatility in material processing and can handle plastics, metals, and ceramics. This technology not only offers economic advantages due to lower material costs but also improves the mechanical properties of printed components.

Daniel Selck, CSO of AIM3D: “Our proven CEM extruders are characterized by material diversity, robustness, and reproducibility. A key advantage of using polymer granulates is the cost benefit in material procurement compared to filament-based 3D printing, as well as the improved mechanical properties. The transfer of CEM technology through application-specific, standalone extruders as universal pellet extruders opens up a variety of new application areas for third-party providers.”

The latest developments include the CEM E2 and CEM E3 extruder models, which are used in AIM3D’s ExAM 255 and ExAM 510 3D printers. These extruders currently achieve build rates of 150 cm³ per hour, with planned increases to up to 600 cm³ per hour. This enables processing volumes of between 1,000 and 4,000 kg per year, further strengthening the industrial application of this technology.

A key feature of CEM extruders is their ability to process high-performance polymers such as ULTEM 9085, known for its high-temperature resistance and mechanical strength. Tensile tests according to DIN EN ISO 527-2 demonstrate high process stability, comparable to injection molding. This makes the technology particularly attractive for industries such as aerospace, automotive, and mechanical engineering.

Thanks to the modularity of CEM extruders, specific adaptations to various industrial applications can be made. The expansion of use cases to large-scale 3D printing, hybrid manufacturing processes, and coating technologies highlights the potential of universal pellet extruders as a flexible tool for industry.
