Integration of Continuous Carbon Fiber Additive Manufacturing Systems

Stratasys Ltd. is expanding its additive manufacturing technology portfolio through the acquisition of Markforged, Inc. from Nano Dimension. The transaction, valued at $42.5 million, integrates Fused Filament Fabrication (FFF) and continuous carbon fiber technologies into the existing manufacturing infrastructure. This operational expansion targets industrial sectors requiring lightweight, high-strength production-ready components, specifically within aerospace, defense, automotive, and industrial manufacturing.

Fused Filament Fabrication and Composite Integration
The technical architecture of the newly acquired systems connects hardware, proprietary material science, and operational software. A core engineering feature of this platform is its continuous carbon fiber reinforcement capability. By embedding continuous strands of carbon fiber during the polymer extrusion process, the system produces composite parts that exhibit higher mechanical strength and lower weight compared to standard thermoplastic FFF methods. This specific material property is required for replacing traditional metal components in weight-sensitive structural applications.

Engineering Applications in Aerospace and Defense
The integration of continuous carbon fiber manufacturing processes supports mission-critical applications within regulated industrial environments. In aerospace and defense sectors, the technology is utilized for manufacturing tooling, fixtures, ground support equipment, and specific end-use production parts. The automated production of these high-performance composites provides an alternative to conventional subtractive manufacturing, improving supply-chain agility and reducing lead times for complex assemblies.

"Additive manufacturing continues to replace traditional manufacturing for high-requirement production applications," stated Dr. Yoav Zeif, Chief Executive Officer of Stratasys. He noted that integrating these composite systems and software platforms directly addresses industrial requirements where mechanical performance, supply-chain resilience, and scalability are essential operational parameters.

Software Architecture and Distributed Manufacturing
Beyond hardware, the technological integration includes specialized software platforms developed for remote production environments and distributed manufacturing workflows. The software infrastructure provides advanced features such as process simulation, part inspection, and security-focused operations. These digital tools enable manufacturing engineers to optimize print parameters automatically, manage part inventory digitally, and maintain the strict quality control standards required in defense manufacturing.

High-Performance Polymers and Material Extrusion
The acquired FFF platforms support a diverse range of high-performance polymer and metal filaments. While the metal binder jetting product line remains with Nano Dimension, the integration of advanced filament extrusion processes broadens the material capabilities available for industrial users. This expanded material portfolio enables manufacturers to match specific mechanical, thermal, and chemical resistance properties to the operational requirements of end-use applications across multiple sectors. The financial and operational consolidation, representing approximately $70 million in 2025 revenue for the acquired assets, is expected to close in the second half of 2026, subject to regulatory approvals.

Additional Context: Technical Specifications and Competitive Benchmarking
Continuous carbon fiber additive manufacturing differentiates itself from short-fiber filled thermoplastics by laying down uninterrupted structural fibers, which significantly increases tensile strength along the toolpath. Within the industrial additive manufacturing sector, this process is frequently benchmarked against automated tape laying (ATL) and selective laser sintering (SLS) of composites. While SLS offers isotropic properties using short fibers, continuous fiber FFF provides highly directional, anisotropic strength that closely mirrors the mechanical behavior of machined aluminum. Consequently, technical evaluation of these systems generally focuses on fiber volume fraction, layer adhesion strength, and dimensional accuracy when assessing suitability for load-bearing industrial fixtures.
