Compound Dynamics’ RM40 Series of large-format enclosed 3D printers offers an expansive build volume of 1,524 × 1,524 × 1,050 mm, more than doubling the capacity of its predecessor. The RM40 Series is well suited for industries requiring large-scale components, such as mold and pattern making, engineering prototypes, automotive manufacturing and industrial equipment production.

This 3D printer use both pellet and filament extrusion to create high-quality parts, including molding prototypes, which can accelerate R&D processes and optimize moldmaking operations.

The series includes a semimonocoque welded steel frame, profiled linear rails and Yaskawa motion control to deliver CNC-like precision, which is not always available in fused filament fabrication (FFF) 3D printing. The RM40 Series also includes an enlarged build volume of 2.25 m² while maintaining an enclosed, heated chamber.

By scaling up its RM30 platform while implementing key engineering improvements, the company says this printer enables manufacturers to tackle projects that were previously only available on open format printers.

The printer incorporates several technological advancements, including a four-motor Z-axis system that ensures precise control and stability for large-scale prints. The system’s dual-extrusion capability includes a Dyze Pulsar pellet extruder alongside an MHZ 2.0 2.85mm filament system to provide material flexibility for industrial applications and an optional copy mode.

Temperature management has also been addressed as the system features comprehensive liquid cooling for all motors and extruders. It also offers 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.

The system also includes onboard pellet drying and hopper systems, travel speeds up to 350 mm/sec. and a robust construction for rigid and stable printing. Its ability to print large parts as single pieces eliminates the need for assembly of multiple smaller components, improving both efficiency and structural quality.
