Our large‑size 3D printing adopts Fused Deposition Modeling (FDM) molten‑extrusion technology. Thermoplastic materials are melted inside the hot‑end nozzle and extruded layer‑by‑layer to fabricate large‑volume parts. Multiple nozzle sizes are optional to balance printing speed, surface finish and layer resolution for diverse project demands.
