Home-Caracol and Formes et Volumes Enhance Aerospace Composite Tooling
Italian 3D printer manufacturerCaracolhas partnered with French manufacturerFormes et Volumesto produce a large-scale composite lamination tool for aerospace using robotic large-format additive manufacturing, combining fiber-reinforced thermoplastics and hybrid post-processing in a single integrated workflow.
Built on the Heron AM platform and already deployed in an active production environment, the project delivers a fully monolithic structure that cuts lead times by 50% and production costs by 30% compared to conventional tooling approaches.
Large-scale composite lamination tools have historically been among the most demanding components to produce in aerospace manufacturing. Traditional approaches rely on multi-part assemblies, extended CNC machining cycles, and tight tolerance stacking, challenges that become more pronounced as part geometry grows. Each additional component introduces new alignment risks, and lead times stretch accordingly, putting pressure on programs that increasingly require faster turnaround and leaner supply chains. Caracol’s Heron AM platform offers an alternative path.
A Lamination Tool Built for Active Production
The component was built using the Heron AM system equipped with a high-flow extruder, purpose-built for robotic LFAM applications requiring high deposition rates and consistent mechanical output. The material selected was polycarbonate reinforced with 20% carbon fiber, chosen for its structural rigidity and low weight. The finished tool measures 2,200 × 2,200 × 600 mm, weighs 180 kg, and was printed in approximately 19 hours, a timeline that would be difficult to match through traditional fabrication at equivalent scale.
The production workflow is hybrid in nature: robotic LFAM establishes the core geometry, CNC machining brings the part to final dimensional tolerances and surface specification, and autoclave post-processing conditions the component for the thermal demands of composite lamination. The result is a fully monolithic structure with no assembly interfaces, removing a category of failure mode that conventional multi-part tooling cannot eliminate.
Measurable Gains Across the Production Chain
The shift to robotic LFAM produced results across multiple performance dimensions: lead time cut by half, production costs down 30%, and both material waste and part weight reduced by 50%.
Beyond the headline figures, the monolithic architecture offers structural advantages that compound over time. Without assembly joints, the tool maintains dimensional stability across repeated use cycles, a meaningful factor where tooling accuracy directly influences the quality of finished composite parts.
