Formes et Volumes chose robotic LFAM to produce composite lamination tools for aerospace image

Caracol partnered with Formes et Volumes to design and manufacture a large-scale composite lamination tool for aerospace production — combining robotic LFAM, fiber-reinforced thermoplastics, and hybrid manufacturing in a single, integrated workflow.

The component is already deployed in an active industrial environment, validating both process reliability and real-world performance. Built with the Heron AM turnkey platform, this project demonstrates what’s possible when monolithic design meets advanced additive manufacturing at scale.

The problem with conventional aerospace tooling

Composite lamination tooling in aerospace has long been constrained by slow, complex processes: multi-part assemblies, extensive CNC machining, and compounding tolerance risks. At large geometries, these issues don’t just persist, they amplify.

Multi-component assemblies increase misalignment risk. Long machining cycles stretch lead times. Logistics and tooling complexity drive up costs. The result is a production model that struggles to keep pace with the demands of modern aerospace programs.

Robotic LFAM changes the equation. By printing directly to near-net-shape geometry, it eliminates assembly steps, reduces cumulative tolerances, and unlocks design freedom that conventional manufacturing simply can’t match.

Manufacturing approach: hybrid workflow, monolithic result

The lamination tool was produced leveraging Caracol’s Heron AM system with a high-flow (HF) extruder, purpose-built for robotic LFAM with high deposition rates and consistent mechanical output.

The manufacturing strategy is hybrid by design:

  • Robotic LFAM produces the near-net-shape geometry with precise robotic control and repeatable process parameters
  • CNC machining delivers the final dimensional accuracy and surface quality
  • Autoclave post-processing ensures the thermal performance required for aerospace composite lamination

The output is a fully monolithic structure with no assembly joints, improved structural integrity, and long-term dimensional stability under demanding operating conditions.

The impact across the production chain and future development

Moving from conventional tooling to robotic LFAM via Heron AM delivered quantifiable gains at every stage:

  • 50% reduction in lead time
  • 30% reduction in production costs
  • 50% reduction in material waste
  • 50% reduction in part weight

Beyond the numbers, the monolithic architecture eliminates assembly-driven failure modes, a critical advantage where structural integrity and repeatability are non-negotiable. Large-format 3D printing also enables engineers to optimize internal geometries and mass distribution directly in the digital design phase, unconstrained by traditional manufacturing limits.

This project with Formes et Volumes is proof point for a broader shift in aerospace production. As robotic LFAM matures alongside hybrid manufacturing workflows, platforms like Heron AM are enabling more agile, on-demand production models, reducing dependency on long supply chains and legacy tooling infrastructure.
