Ultimaker’s New Metal Filament: Redefining Desktop 3D Printing with Real Metal Parts

In a breakthrough that’s reshaping the limits of desktop 3D printing, Ultimaker has launched its new Metal Expansion Kit, bringing true metal part production to its professional line of Fused Deposition Modeling (FDM) 3D printers. This innovation positions Ultimaker as the only FDM machine in the world with a complete, certified solution for metal printing—on the same platform trusted by engineers and designers globally.

Real Metal Printing. Now on Your Desktop.

Traditionally, metal 3D printing has been exclusive to large-format, high-cost systems like DMLS or SLM, with complex setup, expensive materials, and high barriers to entry. Ultimaker changes this landscape by offering a cost-effective, office-friendly solution for metal part fabrication—using standard FDM technology.

With the Ultimaker Metal Expansion Kit, users can now print in stainless steel (17-4 PH and 316L) directly from their S5 or S7 machines, turning accessible 3D printers into powerful tools for:

Functional prototypes
Tooling and fixtures
End-use mechanical components
Corrosion-resistant or high-strength applications

How It Works

The Ultimaker metal printing workflow is designed for simplicity and professional results:

Print metal-loaded filament using a compatible Ultimaker printer.
Debind and sinter the printed part through an approved post-processing partner.
Receive a fully dense, functional metal part—all without investing in high-end metal additive machines.

The kit includes:

BASF Ultrafuse® 17-4 PH and 316L filaments
Print cores, hardened nozzles, and support materials
Access to slicing profiles in Ultimaker Cura
Integration with debinding/sintering services via BASF’s network

What Makes Ultimaker Unique?

Ultimaker is the first and only company to offer a certified, end-to-end metal FDM workflow that combines:

Trusted desktop printers (Ultimaker S5 / S7)
Advanced material science from BASF
Seamless software integration (Ultimaker Cura)
Commercial post-processing partnerships

This plug-and-play approach democratizes access to metal printing without compromising quality or safety. It’s a game-changer for:

Engineering departments needing quick-turn metal parts
R&D teams testing prototypes under real-world conditions
Manufacturers building low-volume custom tooling or jigs

Benefits of Ultimaker Metal Printing

✅ Lower cost of entry vs. industrial metal printers
✅ Compact and safe for office or lab environments
✅ Material flexibility — print plastic and metal on the same machine
✅ Easy integration with established debinding and sintering workflows
✅ High strength and durability with genuine stainless steel parts

A New Era of Possibility

Ultimaker’s metal filament offering represents a bold leap forward in the world of accessible 3D manufacturing. By merging material innovation, intelligent software, and hardware versatility, Ultimaker now empowers users to do what was once impossible: print real metal parts, affordably and efficiently—on the same FDM printer they already trust.

This is not just an upgrade. It’s a revolution.
