No tooling, no long lead times, just strong, accurate metal parts straight from your printer.
Compatible with the Markforged Metal X system, steel filament enables you to produce functional stainless parts in-house. Whether you're replacing machined components or prototyping for production, this filament delivers consistent performance.
What Is Steel Filament For?
Steel filament is designed for engineers, manufacturers and R&D teams who need dependable metal components for real-world use. With outstanding mechanical properties and surface finish, it’s ideal for structural parts, tooling, and end-use components.
Popular applications include:
• Functional prototypes that mirror final metal parts
• Production tools, jigs and fixtures built to last
• Replacement components with tight tolerances
• Wear-resistant parts for automotive and industrial settings
Steel filament is commonly available in stainless steel variants like 17-4 PH, which offers high strength and corrosion resistance, and H13 tool steel, known for hardness and thermal durability.
Why Choose Steel Filament?
Steel filament gives you the freedom to create parts traditionally reserved for CNC machining or casting. With additive manufacturing, complex geometries are easy, iteration is fast, and costs stay down.
Here’s what makes steel filament a standout option:
• Exceptional part strength with industrial-grade finishes
• Reduced production costs for one-offs and small batches
• Design flexibility for complex, internal features
• Faster turnaround without outsourcing or delays
• Reliable printing with the Markforged Metal X workflow
