Alex Huebner joins HAMR for the Summer!

We are excited the news has finally been revealed that Neighborhood 91 is bringing in FormAlloy Technologies, Inc. newest machine, the X5R, which will be housed at HAMR!

The power of cold spray is clear. The underlying science of its bonding? Not so clear...

Did you know that cold spray was traditionally used for coatings and repairs? Cold spray coatings typically exhibit lower porosity and oxide content compared to traditional thermal spray methods.

The success of cold spray deposition hinges on exceeding a 'critical velocity' for the powder particles. This critical velocity isn't a fixed number; it varies significantly depending on the feedstock material, particle size, and the substrate material. For instance, softer metals like aluminum will generally have a lower critical velocity compared to harder materials like titanium or nickel superalloys. Passing this number is key to the success of cold spray! However, these relationships are complex, and to this day there is not a consensus on a predictive model for critical velocity.

Leading up to Cold Spray Action Team conference next week, we'll be providing a new cold spray factoid each day!

HAMR Industries had the honor touring the Steel City Spark Cell innovation officers through our space. The officers also got to tour Metal Powder Works.

Scalability is one of the biggest advantages of Cold Spray Additive Manufacturing (CSAM). With our WarpSPEE3D system, we can build components up to 40 kg and Ø1m x 0.7m in a single print—at impressive speeds of up to 6 kg/hr! From quick-turnaround parts produced in minutes to large-scale builds completed in hours, CSAM offers unmatched flexibility across a broad range of materials.

In case you missed it at MILAM 2025, HAMR and Freemelt AB showed off some recent AM tungsten builds!

TBCs are utilized in high temperature environments, such as gas turbine engines, to insulate from the high heat loads and can withstand large temperature differentials - over several hundred degrees Celsius, while the thickness of a little more than a human hair!

In February, HAMR ventured to MILAM 2025 and was able to show off some large builds, including this one which was teased at the start of the new year! Stay tuned for the full assembly!

As 2024 comes to a close, we reflect on another year of success and growth. We are very proud of what our small team is able to accomplish.

As the year ends and the crew gets ready for MILAM 2025, we have started the process of making a large assembly of parts all made with CSAM.

Wishing you and your loved ones a joyful and festive holiday season. Here's to a bright and exciting 2025 ahead!
