Technology & Products
Key Products
["EXF-12 - Large-format pellet-type 3D printer with FANUC controller, housed in 12-foot container with maximum build dimensions of 1700×1300×1020mm","REX-BUTLER - Collaborative robot-based 3D printer featuring multi-axis printing capabilities with integrated cutting and forming functions","Butler Method™ - Proprietary collaborative robot-based design philosophy for large-format pellet 3D printing addressing print quality, stable operation, on-site implementation, and operational costs","BOLDGYM ACADEMY - Membership-based manufacturing training gym providing access to 3D printing systems and resources","Custom 3D Print Heads - Proprietary pellet extrusion printheads for industrial applications"]
Technological Advantage
Three core differentiators: (1) Direct pellet melting eliminates expensive filament dependency, reducing material costs by up to 90%; (2) High-speed large-scale production achieving 15kg/hour output for components up to 1700×1300×1020mm; (3) Material flexibility supporting diverse recycled and sustainable plastics including bio-based polymers, supporting Green Creative™ sustainability initiative
Differentiation
Value Proposition
Enables low-cost, high-speed production of large components (up to 1700×1300×1020mm) using inexpensive plastic pellets and recycled materials, achieving 15kg/hour output rate at dramatically reduced material costs compared to traditional filament-based 3D printers
How They Differentiate
ExtraBold differentiates through: (1) Proprietary 'Butler Method' collaborative robot-based pellet 3D printing technology with integrated multi-axis printing, cutting, and forming capabilities; (2) FANUC industrial controller integration for enterprise-grade reliability; (3) Green Creative™ initiative focused on sustainable materials including recycled plastics and bio-based polymers; (4) Direct pellet-fed technology achieving 15kg/hour output at up to 90% lower material costs; (5) Unique container-housed EXF-12 system with 1700×1300×1020mm build volume for on-site deployment
