Engineered for UltiMaker S3 and S5 2.85mm print cores, the Call3D purpose-built Ultimaker 1.75mm nozzle enables full compatibility with the global standard 1.75mm filament. Unlock thousands of specialized, engineering-grade, and composite filaments only available in 1.75mm format, while reducing material costs by 15-30% compared to scarce, expensive 2.85mm options. Enjoy universal sourcing convenience, faster melt response, sharper details, reduced oozing, and stable extrusion with flexible and abrasive materials. Designed to fit UltiMaker hot-end geometry for reliable, jam-resistant 1.75mm performance.

Stock UltiMaker 2.85mm nozzles lock you into limited, expensive, and hard-to-source 2.85mm filament. Our Ultimaker 1.75mm nozzle unlocks access to thousands of mainstream, affordable materials with faster availability and greater variety.
While full conversion requires one of three setup methods (covered in our upcoming blog), this nozzle ensures stable, high-quality 1.75mm extrusion once configured — far superior to generic nozzles that cause jamming, oozing, and poor layer quality.

Most generic 1.75mm nozzles are simply drilled-down standard nozzles — they do not match UltiMaker’s 2.85mm core geometry, leading to backflow, leaks, inconsistent extrusion, and frequent jams.

Our Ultimaker 1.75mm nozzle is engineered specifically for the UltiMaker hot end structure with optimized length, seating, and inner flow path. This eliminates gaps, improves sealing, and delivers stable, reliable 1.75mm performance that generic nozzles cannot match.
