Compound Dynamics Launches RM40 Series, Setting New Standards in Enclosed Large Format 3D Printing

Compound Dynamics has announced the launch of its RM40 Series large format enclosed 3D printer, marking a significant advancement in industrial additive manufacturing capabilities. The new printer, which began shipping to customers in September 2024, features an expansive build volume of 1524mm x 1524mm x 1050mm, more than doubling the capacity of its predecessor.

The RM40 Series 3D printers build upon the legacy of the RM30 Series, a large format 3D printer which uses both pellet and filament extrusion to create high-quality parts. The RM40 Series retains the same high-end features that made the RM30 Series stand out, including a semi-monocoque welded steel frame, profiled linear rails, and Yaskawa motion control, delivering CNC-like precision that is rare in FFF 3D printing. Expanding on this foundation, the RM40 Series enlarges the build volume to 2.25 cubic meters while maintaining the enclosed, 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 new 3D printer incorporates several significant technological advancements, including a sophisticated four-motor Z-axis system that ensures precise control and stability for large-scale prints. The system's dual extrusion capability, featuring a Dyze Pulsar™ pellet extruder alongside an MHZ 2.0 2.85mm filament system, provides unprecedented material flexibility for industrial applications.

Temperature management, a critical factor in large-format printing, receives particular attention in the RM40's design. The system features comprehensive liquid cooling for all motors and extruders, a high-temperature tempered glass print surface capable of reaching 150°C, and an enclosed build chamber maintaining up to 60°C passively, with optional heating to 85°C available.

Key Features of the RM40 Series:

• 524mm x 1524mm x 1050mm build volume

• Dual extrusion capability with optional copy mode

• On-board pellet drying and hopper systems

• Travel speeds up to 350mm per second

• Robust construction for rigid and stable printing

  
  

The RM40 Series is particularly valuable for industries requiring large-scale components, such as mold and pattern making, automotive manufacturing and industrial equipment production. Its ability to print large parts as single pieces eliminates the need for assembly of multiple smaller components, improving both efficiency and structural integrity. 

Available in various configurations to meet specific manufacturing needs, the RM40 Series is priced from $240,000 to $310,000, reflecting its position as a premium industrial manufacturing solution.

“I think this machine is a great fit for the pattern and mold making industries, as well as engineering prototypes,” Jared Wesenick added.
