The company Compound Dynamics has introduced the RM40 Series, a new large-format 3D printer designed primarily for industrial applications. Since September 2024, the device has been delivered to customers and offers a significantly expanded build volume of 1524 mm x 1524 mm x 1050 mm compared to its predecessor, the RM30 Series.
The RM40 Series builds on the proven technology of the RM30 Series, combining pellet extrusion with traditional filament processing. Its construction features a welded semi-monocoque steel frame, profiled linear guides, and a high-precision Yaskawa motion control system, achieving CNC-like accuracy in the Fused Filament Fabrication (FFF) process. Despite the increase in build volume to 2.25 cubic meters, the printer remains enclosed in a heated chamber.
“The RM40 Series represents a significant development in large-format 3D printing technology,” said President Jared Wesenick. “By successfully scaling up our proven RM30 platform while implementing crucial engineering improvements, we’re enabling manufacturers to tackle projects that were previously only available on open format printers.”
The RM40 is seen as an alternative to conventional manufacturing methods, particularly in industries such as mold and tool making, automotive production, and industrial manufacturing.
Technical advancements focus on mechanical precision and temperature management. The RM40 features a four-motor Z-axis system to ensure stable guidance of large print objects, as well as a dual extrusion unit with a Dyze Pulsar™ pellet extruder and an MHZ 2.0 filament system. Its integrated liquid cooling system ensures thermal stability, while the heated print bed can reach up to 150°C. The enclosed build chamber can maintain a passive temperature of 60°C, with an optional heating system increasing it to 85°C. “I think this machine is a great fit for the pattern and mold making industries, as well as engineering prototypes,” Jared Wesenick added.
With a maximum travel speed of 350 mm/s and the ability to print large components as a single piece, the RM40 reduces assembly effort and enhances the structural integrity of printed parts. The price range for the printer is between $240,000 and $310,000, depending on configuration and features.
