Cold Metal Fusion Material and Production Services
What is Cold Metal Fusion?
Cold Metal Fusion (CMF) is an advanced manufacturing process that combines the flexibility of additive manufacturing with the strength and durability of metal parts. This process uses a unique combination of metal powder and polymer binding agents, which are selectively fused layer by layer to create high-strength metal components. The result is a process that not only delivers the same quality as traditional methods but also offers increased design freedom, faster production times, and reduced material waste.

Precision and Accuracy
CMF technology allows for the production of intricate and complex geometries with high precision, meeting the most stringent quality standards.
Material Efficiency
The additive nature of CMF reduces material waste, making it a more sustainable option compared to traditional subtractive manufacturing methods.
Affordable Pricing
With CMF, you can achieve designs that would be impossible or prohibitively expensive with conventional manufacturing techniques.
Speed
CMF enables faster production cycles, reducing lead times and accelerating your time-to-market.
Titanium (Ti6Al4v)
Renowned for its exceptional strength-to-weight ratio, titanium also offers superior corrosion resistance and biocompatibility. This makes it an ideal choice for applications in the aerospace and medical fields. The Ti6Al4V alloy (Grade 5) is the most widely used titanium alloy worldwide.
Stainless Steel 316L
One of the most popular metals globally, Stainless Steel 316L is commonly used for mechanical components requiring high corrosion resistance. This material is suited for operations up to 842°F (450°C) and is easily weldable, making it perfect for demanding applications.
Stainless Steel 17-4PH
A stainless and hardenable alloy that combines excellent mechanical properties with outstanding corrosion resistance. Stainless Steel 17-4PH is typically employed in industrial settings where both strength and corrosion resistance are critical.
The best of both worlds
Material spectrum of powder metallurgy
By integrating metal powder into our highly functional binder system, all metals in powder metallurgy are available for additive processing.
Up to 90% lower part costs
Low system and operating costs as well as a significantly higher part output result in up to 90% lower part costs.
High green part stability
Our high green part stability enables easy post-processing like turning, joining, milling or drilling. This is an enormous advantage, especially for alloys that are difficult to process.
Full reusability of the feedstock
Not processed feedstock can be fully reused.
8x higher part output
Processing our feedstock on SLS systems enables a high part output, which allows real series production for the first time.
Metal parts with familiar characteristics
In addition to a density of up to 99.9%, our metal parts also have the same properties as those from other powder metallurgical processes.
Reliable and widespread machinery
SLS systems, debinding systems and sintering furnaces are reliable, widespread and easy to maintain. And in addition to the established providers, our process also runs on SLS entry-level machines.
40x higher part output within reach
Developments in the SLS-technology, especially diode lasers, will bring significant productivity leaps.
Answers to Frequently Asked Questions
Not at this time, CADmore specializes in providing cold metal fusion (CMF) powder and providing insight on the CMF process.
None. All showcased parts were successfully produced on the first attempt.
Green parts have sufficient strength to withstand water blasting at pressures around 40 psi.
No. Although both use Selective Laser Sintering (SLS) technology, Cold Metal Fusion involves entirely different chemical and physical processes.
Cold Metal Fusion provides higher density compared to traditional binder jet processes.
Cold Metal Fusion Powder is compatible with a wide range of machines, including those equipped with CO₂ lasers, fiber lasers, or even 5-watt diode lasers. Parts printed in the green state can be shipped to CADmore for sintering and post-processing services.
The material combines pure Ti6Al4V powder with a proprietary polymer binder, giving it a safer handling profile compared to conventional titanium feedstocks. This binder also simplifies post-processing and helps maintain powder integrity during printing. As a result, you get the benefits of metal 3D printing—like creating robust, lightweight titanium parts—without many of the usual storage and safety headaches.
Cold Metal Fusion relies on uniform shrinkage during sintering to achieve consistent dimensional accuracy. Even for heavier parts—like a 1 lb (0.43 kg) titanium build—you’ll see precise results as long as you account for the known shrink factor in your design. This makes it possible to produce substantial titanium components without the warping or inconsistencies that can occur in other processes.
If you already have an SLS machine, you’re most of the way there. By using a compatible titanium feedstock designed for Cold Metal Fusion, you can print your own green parts in-house. After you’ve created the green parts, partnering with a CMF service provider for post-processing—sintering, finishing, and final checks—ensures professional results without a significant additional investment in new hardware.
