Technology & Products
Key Products
Senju SV-04 auto-tool-change FFF 3D printer (nozzle diameters 0.4-1.8mm, build volume 380x350x400mm, up to 4 tools); MIRROR FARM print farm (120 units) for contract manufacturing; recycled filament materials; Prusa Research printer resale.
Technological Advantage
Proprietary CL (tool-change) attachment/detachment mechanism enabling automatic multi-nozzle tool changes on a single FFF machine; vertically integrated pipeline from waste-material sourcing to filament production to print-farm-scale output.
Differentiation
Value Proposition
Domestically-developed auto-tool-change FFF 3D printer (Senju SV-04) built on manufacturing know-how from decades of doll-craft production, paired with in-house recycled filament development and large-scale print-farm production capacity.
How They Differentiate
Combines traditional Japanese craft manufacturing heritage with domestically engineered auto-tool-change hardware and a circular-economy (waste-to-filament) materials strategy, rather than importing hardware.
Market & Competition
Target Customers
Manufacturers needing prototyping and low-volume/one-off production; industrial users seeking recycled-material parts (e.g. automotive scrap-material reuse).
Industry Verticals
