Moi Composites Unveils the Hybrid Fabrication Platform: Revolutionizing Large Format Additive Manufacturing for Thermoset Composites
Introduction to the Hybrid Fabrication Platform (HFP) Series
In a landmark announcement, Moi Composites, a pioneer in composite materials manufacturing, has commenced commercial production of its groundbreaking Hybrid Fabrication Platform (HFP) series. This industrial-grade system is poised to transform large format additive manufacturing (LFAM) specifically tailored for thermoset composites. After extensive R&D spanning hardware engineering, advanced software development, and cutting-edge materials science, the HFP series seamlessly integrates short fiber manufacturing (SFM) technology with precision milling capabilities within a versatile modular digital platform.
This integration strikes an optimal balance between unprecedented design freedom, superior material performance, and enhanced process efficiency—critical factors for industrial-scale applications. By converging thermoset composite deposition and subtractive precision machining in a unified environment, the HFP eliminates the inefficiencies of traditional multi-equipment serial workflows, which often lead to prolonged lead times, increased costs, and cumulative error propagation in composite production pipelines.
Core Components: The S18 SFM Printhead and Modular Adaptability
At the heart of the HFP series lies the newly developed S18 SFM printhead, engineered for both comprehensive system integration and standalone modular operation. This flexibility allows seamless adaptation to existing robotic production units, enabling manufacturers to upgrade legacy systems without overhauling entire setups. The SFM process leverages robotic arms to deposit next-generation reinforced thermoset materials laden with high short fiber content. These materials deliver exceptional mechanical properties—such as high tensile strength, impact resistance, and fatigue endurance—coupled with superior molding precision.
Scientifically, short fiber reinforcement in thermosets enhances isotropic properties compared to continuous fiber methods, reducing anisotropy while maintaining high fiber volume fractions (often exceeding 30-40%). The deposition mechanism involves precise extrusion of fiber-resin mixtures, where the short fibers (typically 1-5 mm in length) align during flow to optimize load transfer, as governed by shear-induced orientation models in rheology.
Visitors to Formnext 2025 will witness a live printing demonstration featuring the sG+A1134 glass fiber reinforced vinyl ester system. This material formulation excels in rigidity (modulus >20 GPa), thermal stability (up to 150°C continuous service), and chemical resistance, making it ideal for demanding environments like aerospace tooling and marine components.
Technical Advantages of SFM Technology in the HFP Series
The HFP series, powered by SFM technology, introduces revolutionary advancements in large-scale composite manufacturing. Key highlights include:
Ultra-High Deposition Rates and Precision Control
The platform’s fast-curing resin system achieves deposition rates of up to 180 mm/second, facilitating high-speed continuous printing without compromising precision. This is enabled by photopolymerization or dual-cure chemistries that trigger rapid cross-linking upon deposition, minimizing flow distortion. Thermodynamically, the exothermic curing reaction is tightly controlled via embedded thermal sensors and feedback loops, ensuring layer-to-layer adhesion strengths exceeding 90% of bulk material values.
Zero-Waste Manufacturing Workflow
A hallmark of the HFP is its zero material waste paradigm: material deposition occurs exclusively in targeted areas, while precision milling removes only superficial traces from prior layers. This subtractive-additive hybrid approach contrasts sharply with traditional LFAM, where oversized prints demand extensive post-machining. Quantitatively, waste reduction approaches 100%, aligning with circular economy principles by minimizing scrap and energy consumption.
Support-Free Printing for Complex Geometries
Rapid curing and algorithmic path planning enable support-free printing, allowing single-step fabrication of intricate geometric structures, overhangs, and undercuts. Finite element analysis (FEA)-driven toolpath optimization predicts deformation risks, leveraging the viscoelastic properties of partially cured thermosets to self-support during buildup. This capability unlocks designs previously infeasible in composites, such as lattice cores or conformal cooling channels in molds.
Material Stability and Operational Simplicity
SFM and continuous fiber manufacturing (CFM) materials from Moi Composites demonstrate outstanding long-term stability, with room-temperature shelf lives of up to 12 months sans pre-drying. This is attributable to stabilized resin formulations incorporating radical scavengers and moisture barriers, obviating the need for controlled humidity environments. Such attributes streamline supply chain logistics, reduce operational overhead, and enhance scalability for high-volume production.
These innovations reinforce Moi Composites’ mission to deliver scalable, high-performance composite manufacturing for near-net-shape parts, requiring minimal finishing margins. The workflow is particularly adept at rapid prototyping and production of high-performance molds, tooling, and functional end-use parts, offering a fast, sustainable, and agile alternative to autoclave-based or resin transfer molding (RTM) processes.
Sustainability and Industrial Impact
From an environmental standpoint, the HFP series minimizes embodied carbon through efficient material use and energy-lean curing (no ovens required). Lifecycle assessments (LCAs) would likely show 40-60% reductions in emissions compared to conventional thermoset processing, driven by localized deposition and recycling potential of uncured scraps.
