With Cold Metal Fusion (CMF) technology and the qualification of the Sinterit Lisa X platform, manufacturers can now explore metal 3D printing without investing in traditional metal printers, using a polymer SLS system instead.
This development represents a major shift toward accessible, scalable metal manufacturing.
ColdMetalFusion (CMF) is a sinter-based metal additive manufacturing technology developed by Headmade Materials.
Unlike laser-based metal printing technologies, CMF separates the process into two clear stages:
1️⃣ Green Part Printing
Metal feedstock containing metal powder and a thermoplastic binder is printed on a polymer SLS system.
Only the binding powder is melted during printing at low temperatures below ~80°C while the metal powder remains solid.
2️⃣ Debinding & Sintering
The printed green parts are debound then processed in a furnace, where the binder is removed and metal particles fuse into a dense, fully metallic component.
Key difference:
Metal properties are achieved during sintering, not during printing.
CMF feedstocks are engineered to work specifically on polymer powder bed fusion (SLS) platforms.
During the printing process:
This enables:
The result is a simpler, more flexible metal AM workflow compared to conventional metal printing.
Headmade Materials has officially qualified the Sinterit Lisa X for printing CMF metal feedstocks.
This qualification confirms that:
It’s an important milestone toward making metal additive manufacturing more accessible to manufacturers who already use or plan to adopt SLS technology.
