An inside look at the properties of metal powder feedstock that can change the dynamics of the 3D printing process. José A. Muñiz-Lerma, Head of Applications R&D at Equispheres shares insights gleaned from his time as a post-doc at McGill University through to today: https://equispheres.com/spheres-make-all-the-difference

👀 Can you spot the difference?

On the left is a microstructure from a print with our non-explosible NExP-1 AlSi10Mg, and on the right is our Performance AlSi10Mg powder.

Don't let the shadows fool you! If you muttered to yourself "those look the same with slightly different lighting" you've got the right idea! So why show this oh so similar side by side? Because it highlights that NExP-1 provides the same, high quality prints as our Performance powder - but with the added benefit of improved safety.

The difference you DON'T see might be the most valuable one we offer.

How will it work in our process? That's often the first question from manufacturers evaluating materials.

For most major LPBF systems including EOS, Aconity3D, 3D Systems, and TRUMPF, we can provide validated parameter sets that enable our engineered aluminum powders to achieve up to 3x faster build rates than traditional powders.

We do not have a one-size-fits-all approach. Our applications engineering team will analyze your specific:
• Machine model and configuration
• Layer thickness requirements
• Surface finish specifications
• Mechanical property targets
• Part geometry complexity

Drawing on our experience with automotive and aerospace manufacturers, we've developed optimized parameter sets that have reduced qualification time by months while improving part consistency and reducing costs by up to 80%.

If you're upgrading powder to better support production applications, our team will help you implement the precise parameters needed to unlock your machine's full potential.

Switching to NExP-1 non-explosible aluminum media for Additive Manufacturing (AM) will have a ripple effect throughout your organization. Your operators will thank you for it. Part designers will thank you for it. Your safety team will thank you for it.

NExP-1 is less hazardous to store and handle, and it makes equipment clean-up quicker and easier. But it retains all the best properties of a high-performance AlSi10Mg aluminum powder: uniformity, faster printing and consistent mechanical properties.

This purpose-built, innovative material reduces the risk associated with day-to-day handling of aluminum powder and makes aluminum AM readily available for production at any scale. No compromise required.

Localized, point-of-need production. Building spare parts on-site or on-board. These are just a few of the projected growth areas for metal Additive Manufacturing (AM).

Now that there’s a safer option for aluminum powder (our non-explosible NExP-1), we're starting to see more use of metal AM outside of traditional manufacturing settings. What's next?

Adsorption is the tendency for a material (molecules, ions, atoms or other particles) to attract a gas or liquid and have it gather on its surface as a thin layer or film. It's a common phenomenon and can make it challenging to work with materials that have high adsorption characteristics attracting undesirable materials into the mix!

A common problem with metal powders has been the thickness of the oxide layer. While a thicker oxide layer results in poor mechanical properties in the final manufactured part, a powder with thinner oxide layers tends to adsorb water, which also has a negative impact on part performance.

However, Equispheres’ powders have both a thin oxide layer and low water adsorption — a direct result of the superior morphology of our powder.

Independent lab testing by McGill University has shown that Equispheres’ powders have an oxide layer half as thick as its competitors, but with one-third the water adsorption.

The result is less powder preparation prior to printing and superior product performance.

Just one more way print material characteristically tuned and purpose-built for metal additive manufacturing makes a difference!

Have you avoided aluminum powder for safety reasons? There are many variables when choosing a particular print material for additive manufacturing, but if the storage and handling concerns of aluminum powder knocked it out of consideration, you can now put it back on the list.

Equispheres offers a safer alternative: NExP-1 aluminum powder. Non-explosible and non-combustible under standard test conditions, it gives manufacturers an option that reduces:

⬇️ the hazards related to handling metal powder;
⬇️ upfront facility investment related to explosion-proofing;
⬇️ ongoing handling/process expenses.

That’s a wrap on RAPID + TCT 2026. It was a great week in Boston.

Plenty of strong conversations, an excellent presentation from Evan Butler-Jones, and an exciting award win alongside Martinrea International.

Thanks to everyone who stopped by the booth, joined the session, and took time to connect with the team. We’re leaving RAPID with even more energy for what’s ahead.

Big moment at RAPID + TCT last night.

We’re proud to share that the Martinrea International Inc. Integrated Passive Cooling project, developed in partnership with Equispheres, won the TCT Automotive & Rail Application Award.

This project shows what can happen when advanced materials, process development, and part design come together. The AM e-motor housing integrated two-phase passive cooling through aluminum v***r chamber structures enabled by a 3D-printed porous wick.

The result:
• 60% reduction in pressure drop
• 39°C winding temperature decrease

A big thank you to the Martinrea team for the collaboration on this project. It’s exciting to see work like this recognized.

If you’re at RAPID + TCT Event, come see us at Booth 1201 today or tomorrow.
