In rural communities across the country, entrepreneurs are building technologies that are changing industries far beyond their own zip codes. Massive Dimension, a CORI Innovation Fund portfolio company based in Barre, Vermont, is a powerful example.

Massive Dimension designs and manufactures high-performance pellet extrusion systems for large-format, commercial 3D printing. The extruder is the part of the system that feeds, melts, and precisely deposits material to create a printed object. In other words, the company builds the technology that helps industrial 3D printers produce large, functional parts — everything from molds and prototypes to furniture, tooling, and end-use components.

Building the tools behind industrial 3D printing

This spring, Massive Dimension took a major step forward on the national additive manufacturing stage with the launch of its new MDX10 LFAM Extruder. Unlike the desktop 3D printers many people are familiar with, large-format additive manufacturing is built for production environments. These systems are designed to print bigger parts faster, using materials that can meet the needs of manufacturers, researchers, and integrators.

That is where Massive Dimension’s technology comes in.

The company’s extruders use resin pellets rather than traditional filament — the spool-fed plastic strand commonly used in many 3D printers. This is an important distinction for manufacturing because pellet-based extrusion can support higher throughput, lower material costs, and a broader range of processable materials. It also opens the door for more flexible, efficient, and scalable production — especially for companies working with large parts or specialized polymers.

The new product debuted at RAPID + TCT 2026 in Boston — one of North America’s leading industrial 3D printing events.

A new extruder designed for where the market is going

The newly launched MDX10 represents a ground-up evolution of Massive Dimension’s proven MD-Series. It is lighter, simpler, and more adaptable, designed to expand the range of applications where pellet extrusion can be deployed across both robotic and gantry-based manufacturing systems.

The MDX10 is 25% lighter than its predecessor and built with 40% fewer parts. That reduction in weight and complexity is significant. A lighter extruder can be used with a wider range of lower-payload industrial robots and collaborative robots, helping manufacturers reduce total integration costs while maintaining the productivity benefits of pellet extrusion.

The simplified architecture also makes the system easier to maintain on the factory floor. Fewer parts can mean fewer failure points, easier access for troubleshooting, and less downtime for operators.

As Massive Dimension Founder and CTO Tyler McNaney put it: “The MDX is not just an iteration. It’s a reset. We removed complexity and reduced weight to create a more capable and more adaptable extrusion system, built for where the market is going.”

That reset includes a series of performance improvements: lower power consumption, improved nozzle clearance for tighter geometries, servo-driven precision for more consistent material control, upgraded heating for improved melt stability, and multiple hot-swappable screw configurations to support a wide range of materials from PLA to high-performance polymers.

Together, these improvements make the MDX10 more than a new product. They position Massive Dimension to meet a growing market need: large-format additive manufacturing systems that are easier to integrate, more adaptable across platforms, and better suited for real production environments.

Bringing Massive Dimension technology to the BigRep ONE platform

Massive Dimension also announced a new partnership with BigRep, a global company known for large-format 3D printing systems. Through the partnership, BigRep is integrating Massive Dimension’s pellet extrusion technology into its BigRep ONE platform.

This partnership is a strong signal of market validation for Massive Dimension. BigRep’s ONE platform is well recognized in the large-format 3D printing space, and integrating Massive Dimension’s technology expands what the platform can do for manufacturers. The combined system is designed to support applications where speed, material flexibility, and cost efficiency matter, including furniture, molds, and functional prototypes.

The two companies demonstrated the integrated system at RAPID + TCT, showcasing its performance capabilities, and are targeting commercial availability by the end of 2026.

A rural company competing on a global stage

Massive Dimension is a great example of what the CORI Innovation Fund was built to support: scalable, technology-enabled companies growing from rural communities, creating quality jobs, and competing in the industries shaping the future.

Its momentum signals what is possible when rural entrepreneurs are not left out of emerging sectors like advanced manufacturing — and why investment in rural companies matters. Too often, promising startups outside major metro areas are overlooked by traditional venture capital simply because of where they are located. Massive Dimension shows what can happen when that gap begins to close.

From Barre, Vermont, to manufacturing floors around the world, Massive Dimension is proving that rural tech companies can innovate, compete, and scale in the industries shaping the next economy.
