Additive Engineering Solutions produces 32-foot CNC mill fixture using LFAM with CFRP and GFRP

Additive Engineering Solutions (AES) has produced a 32-foot CNC mill fixture using large-format additive manufacturing (LFAM) with carbon fiber- and glass fiber-reinforced polymers, machined to ±0.010-inch profile tolerances. The tooling, highlighted at CAMX 2026, targets composite layup, forming, and assembly applications. AES demonstrated the fixture as part of its broader LFAM tooling portfolio, which includes patterns for composite layup molds, forming dies, and assembly jigs. The company uses pellet-fed extrusion systems to deposit reinforced thermoplastics, then post-machines the near-net shape to final tolerances.

This development underscores the growing industrial acceptance of LFAM for large-scale tooling, particularly in aerospace and automotive composite manufacturing. The 32-foot fixture addresses a persistent gap in the market: traditional CNC mill fixtures of this size require weeks of lead time and significant material waste from subtractive machining of aluminum or steel billets. AES’s approach, using CFRP and GFRP pellets, reduces both cost and cycle time while maintaining dimensional accuracy sufficient for composite layup tooling. The achievement aligns with the broader trend of AM moving from prototyping into production tooling, where the value proposition is clear-lower upfront investment, faster iteration, and reduced material waste-without requiring the qualification burden of serial production parts.

For buyers evaluating LFAM tooling, the key takeaway is that AES has demonstrated repeatable accuracy at a scale that competes with traditional machined fixtures. The ±0.010-inch tolerance is not exceptional for CNC machining, but it is notable for a 32-foot additively manufactured part. The practical next step for AES is to build a track record of delivery reliability and surface finish consistency across multiple customers and part geometries. For end users, this is a viable option for low-volume, large-format tooling where lead time and cost are the primary constraints.
