ROBOZE 3D Prints CubeSat 3U Structure for Italian Space Manufacturer NESST

ROBOZE Helps NESST Srl 3D Print a CubeSat 3U Structure

ROBOZE has supplied its Argo 500 3D printing systems to NESST Srl, an Italian aerospace and defense manufacturer, for the production of a CubeSat 3U structural body. The project marks another step in the Italian company's push to bring additive manufacturing into certified space hardware.

NESST Srl, based in Italy, specializes in precision mechanical components for aerospace, defense, and satellite applications. For this project, the company turned to ROBOZE's large-format, high-temperature 3D printing platforms to produce the structural frame that holds a CubeSat 3U satellite together.

Why 3D Printing for Satellite Structures

Traditional satellite structure manufacturing relies on CNC-machined aluminum or titanium billets. The process is slow, expensive, and generates significant material waste. 3D printing offers an alternative: parts come out close to final geometry, material usage drops, and design changes can be made in software rather than on the shop floor.

For small satellites like CubeSats, every gram counts. A lighter structure means more payload mass or a smaller launch vehicle. ROBOZE's carbon-fiber-reinforced PEEK and PEI (ULTEM) printing capabilities are particularly relevant here. Those materials meet flame, smoke, and toxicity requirements for spacecraft interiors and survive the vibration and thermal cycling of launch.

ROBOZE's Role in Parameter Optimization

According to TCT Magazine, which first reported the project, ROBOZE supported NESST Srl during the testing phase by helping define optimal 3D printing parameters. That support matters. PEEK and PEI print at temperatures that push most desktop machines to their limits. Bed temperatures above 160 degrees Celsius and nozzle temperatures above 380 degrees Celsius are standard for these materials, and consistent interlayer bonding is critical for structural integrity.

ROBOZE's Argo 500 platform features a closed, temperature-controlled build chamber and a high-flow hotend capable of handling both PEEK and PEI. The company has positioned the Argo line specifically for industrial and aerospace customers who need repeatable, certifiable parts rather than one-off prototypes.

CubeSat 3U Standard

A CubeSat 3U measures roughly 10 by 10 by 30 centimeters. It is one of the most common small satellite form factors in use today. Universities, startups, and national space agencies all launch CubeSats for technology demonstration, Earth observation, and communications research. The structural body of a CubeSat must survive launch vibration, maintain dimensional stability in orbit, and protect internal electronics from thermal extremes.

NESST Srl's use of additive manufacturing for this application signals growing confidence in 3D printed space hardware. Several years ago, the idea of a 3D printed satellite structure would have required extensive material testing and regulatory justification. Today, the aerospace industry is actively incorporating AM parts into flight hardware.

What It Means for Small-Batch Space Hardware

The NESST Srl project is also worth watching from a supply chain angle. Satellite programs often require low production volumes, sometimes just a handful of units. Traditional manufacturing setups for aluminum or titanium parts involve expensive tooling and long lead times. 3D printing removes that constraint. A design can be finalized, printed, tested, and revised in weeks rather than months.

ROBOZE has been steadily building its aerospace credentials. The company's Italian roots and focus on high-performance thermoplastics position it well in the European space supply chain, where organizations like ESA and the Italian Space Agency actively seek domestic manufacturing partners.

The Bigger Picture

This project fits into a broader trend: space hardware manufacturers are treating 3D printing as a standard tool rather than an experimental one. From rocket engine components to satellite brackets to full satellite bus structures, additive manufacturing is earning its place on the flight hardware manifest. ROBOZE's involvement with NESST Srl is one concrete example of that shift.
