Xometry 择幂科技帮助将 AcubeSAT 从原型打造为可发射的纳米卫星

We designed it with maximum strength-to-weight efficiency in mind, combining tight tolerances with complex geometry. Since producing a part this precise was beyond our in-house capabilities, we relied on external manufacturing to bring it to life. Working with Xometry’s digital manufacturing platform proved to be a practical solution. The ordering process was simple, and the part was delivered exactly to spec, which helped us stay on schedule and move forward with system integration.

We can’t imagine any other partner who could have been able to deliver the parts in time to allow us to launch the product and exhibit it at Formnext.

For the physical prototype, I selected Selective Laser Sintering (SLS) using PA12 nylon. This combination offered the durability and dimensional accuracy I needed, while being light enough to preserve the model’s integrity and strong enough to handle repeated use. I ordered the parts through Xometry’s on-demand manufacturing service, which allowed me to test my designs without investing in a printer or tooling—a crucial advantage when working with small volumes and evolving prototypes.

We came up with three different prototypes and then around May we ordered all of the aluminum parts and expensive cameras. For the prototyping, Overwatch relied on two in-house 3D printers and Xometry.

Xometry has always given us exactly what we needed. We’ve received parts with holes in the right places, with the right finish, and on time. Even having a user-friendly website, with options laid out in a logical way, translates to a faster turnaround time for us.

We used it to fabricate our canister design out of nylon and plated it with copper and nickel to ensure air tightness. In school we’ve all learned how to use 3D printing, but we always use plastics or acrylics, basic materials. Working with Xometry really expanded our horizons when it came to using materials like nylon, copper plating, and nickel. These are materials we’d never worked with before, and that was really cool to see.
