Suitable for a Wide Range of Prints



Well-suited for toys, mechanical parts, and decorative objects, this nozzle handles both functional and aesthetic models with reliable consistency.

0.2mm Nozzle – Optimal Print Fineness



The smaller nozzle diameter extrudes thinner filament lines, enabling higher detail resolution and finer surface quality, especially on horizontal print surfaces where precision and smoothness are critical.
