Technology & Products
Key Products
FDM Filaments (PLA, ABS, PETG, TPU, Silk, Wood, Carbon Fiber, Rainbow); UV Resins (Standard, Water Washable, Dental Model, Castable, High Toughness); 3D Printing Pens; Industrial-grade specialty filaments
Technological Advantage
Vertical integration of R&D and production lines allows for strict quality control over diameter tolerances (±0.02mm for filaments) and chemical stability in resins, reducing post-processing requirements for end-users.
