Why Cold Metal Fusion

A production-focused approach to metal additive manufacturing.

Repeatable by Design

Cold Metal Fusion is built on mature SLS printing and sintering workflows, delivering consistent results from build to build without constant parameter turning or outcome uncertainty.

Designed to Scale

CMF supports batch-based production with predictable throughput, making it suitable for mid to high volume manufacturing - not just prototyping or one off parts.

Production-Grade Materials

From titanium to stainless steels and nickel-based superalloys, Cold Metal Fusion supports a growing range of alloys used in industrial, energy, and defense applications.

Great Economics

Lower system costs, 100% material utilization, and scalable throughout enable Cold Metal Fusion to achieve meaningful cost advantages over legacy manufacturing methods.

The Cold Metal Fusion Process

From powder to dense metal parts in three controlled steps

Print

SLS printing at (50° C) sinters the polymer bound metal feedstock to produce robust green parts. 100% of non-sintered powder is fully recycled - no refresh required.

Debind

Green parts undergo chemical debinding to remove the primary binder while preserving geometry.

Sinter

Brown parts are loaded into a vacuum furnace, where the remaining stage 2 binder is removed before the metal feedstock is sintered into its final form.

Predictable Dimensional Accuracy

Uniform, Isotropic Shrink - By Design

Dimensional accuracy is not a "nice to have" in metal additive. For most OEMs, it's the gating factor between prototyping and real production. This is where Cold Metal Fusion (CMF) is fundamentally different.

CMF parts shrink isotropically during de-binding and sintering. That means the geometry scales down evenly in all directions, rather than warping, drifting, or distorting unpredictably.

The result is parts that come out of the furnace where you expect them to be - without guesswork, excessive offsets, or iterative tuning.

Applications Built for Production

Cold Metal Fusion enables cost-effective metal parts across demanding industrial applications.
