Introducing the ZRU: 4-Head Multi-Color FDM 3D Printer

May 15, 2026 — Product Launch

We're proud to announce the launch of the WonderMaker ZRU (ZR Ultra), our new flagship FDM 3D printer featuring 4 independent print heads for true multi-color, multi-material printing.

The Problem With Traditional Multi-Color Printing

Most FDM printers achieve multi-color printing through a single nozzle that purges and switches filaments between colors. This wastes enormous amounts of filament — sometimes more material is purged than used in the actual print. It also dramatically increases print time.

Our Solution: 4 Independent Nozzles

The ZRU's 4-head system eliminates purge waste almost entirely — up to 99.9% less waste compared to single-nozzle multi-color systems. Each nozzle operates independently, depositing its own color or material exactly where needed.

With software color dithering, the ZRU can produce the perception of up to 16 colors by interlacing filament colors across layers, giving stunning visual results.
