Prime towers are supposed to be boring. This one accidentally taught us something.

We were running a Cu29 test when we noticed something we were not actually testing for.

Bridging. With an all-metal filament.

Those silver lines in the photo are Cu29 hanging unsupported between two points.
For anyone outside 3D printing, bridging is when the printer extrudes material across an open gap with nothing underneath it. With normal polymer filament, you can tune for it.

With Cu29, we expected this to be much harder.

Cu29 is molten metal coming out of an FDM nozzle, with very low viscosity compared with a thermoplastic. We assumed getting clean unsupported spans would take some serious printer tuning.

Instead, our prime tower started doing it on its own.

It is not perfect, and we are not calling this a finished bridging specification yet. But seeing free-hanging Cu29 spans show up during an unrelated test was one of those “well, that’s interesting” moments.

Sometimes the best R&D results are the ones you weren’t looking for.
Now we get to see how far we can push it.

, do you think we’re flexible enough yet? 😂

We were messing around with one of our Cu29 breadboard test prints and I bent it just to see how far it would go.

Turns out, pretty far.

The conductive pathways are printed directly with Kupros Cu29, our all-metal, conductive filament, and the whole electronic structure can flex right along with the polymer.

No copper tape. No conductive ink added afterward. No rigid PCB sitting on top of it.
Just 3D printed electronics bending with the part.

And honestly, this was not even supposed to be a flexibility demo. I was just curious what would happen.

Now I want to see how far we can push it.

Turn your 3D printer into an electronics factory.

This isn’t a rendering or a roadmap. We printed every one of these.

Antennas. Embedded wiring. Sensors. Induction coils. Flexible electronics. Strain gauges. Circuit features. Electronic components built directly into the print.

All using Kupros Cu29, our all-metal, conductive filament for FDM/FFF.

No plating. No sintering. No curing. No post-processing just to make the conductive features work.

The goal is pretty simple: print the structure and the electronics in the same build.
That’s what we mean by turning a 3D printer into an electronics factory.

It is the component.

This is a 3D printed induction coil, created directly inside an FDM part using Cu29.

No separate copper coil.
No wiring harness.
No component mounted afterward.

The geometry printed into the structure becomes the passive electronic component itself.

That is the part of 3D printed electronics I think changes everything.

Print the passive electronics. Embed the active electronics. Build the system as one part.

09/17/2026

What if your 3D printed part could monitor its own structural health throughout its service life?

This is a 3D printed strain gauge made with Cu29, integrated directly into an FDM part.

By monitoring changes in strain over time, embedded sensors like this could help track deformation, fatigue, damage, and structural condition without adding a separate sensor package.

Print the structure. Build the sensing into it.

This is an all-metal, conductive filament printing directly from a standard FDM printer.

Not ink.
Not paste.
Not conductive polymer.

Metal. Printed like filament.

Cu29 is the first of its kind, opening the door to printing circuits, antennas, sensors, power paths, and embedded electronics directly into 3D printed parts.

No sintering. No curing. No post-processing.

This is what 3D printed electronics is starting to look like.

This is FDM moving into electronics manufacturing.

Kupros has developed a patent-pending process for embedding electronic components directly into 3D printed parts themselves using our all-metal filament formulation.

That means structure, conductive pathways, and electronics can be manufactured as one integrated system.

The same process can extend into exotic polymers, ceramics, and mission-specific energetic applications.

Fewer parts. Less assembly. More capability built directly into the structure.

These are the structural arms from our 3D printed CubeSat mock-up.

The silver lines are Cu29 conductors embedded directly into the arms.

The idea is simple: instead of routing a separate wiring harness through the spacecraft, make the structure itself carry power.

Because Cu29 can support high-voltage and high-current applications, these embedded conductors can function as power buses built directly into the part.

That means fewer wires.
Fewer connectors.
Fewer separate components.
Less assembly.

And more of the electrical system becomes part of the structure itself.

We are demonstrating it here with a CubeSat, but the same concept applies to drones, robotics, aerospace systems, and other platforms where SWaP matters.

This is the direction we see additive manufacturing going.

Not just printing the structure.

Printing the electrical architecture into it.

09/06/2026

Sometimes scale says more than a datasheet.

That line next to the tip of the pen is a 3D printed Cu29 conductive trace.

And it is not sitting on a rigid board. The substrate is flexible.

That combination matters.

Fine conductive features.
Flexible geometries.
Standard FDM manufacturing.
Electronics that can begin conforming to the shape of the part instead of forcing the part to conform to the electronics.

We are continuing to push how small, flexible, and integrated we can make these printed electrical features.

For drones, spacecraft, defense systems, wearables, sensors, robotics, and other applications where size and geometry matter, that opens up some very different design possibilities.

The pen is there for scale.

The trace is the interesting part.

09/01/2026

This CubeSat mock-up is really about one thing: SWaP.

Size. Weight. Power.

Instead of treating the wiring harness as a separate system that has to be routed, secured, connected, and maintained, we’re embedding the power buses directly into the structural arms of the CubeSat.

That means fewer wires, fewer connectors, fewer separate components, and more of the electrical architecture becoming part of the structure itself.

The other piece we’re demonstrating here is resolution.

The Cu29 traces can be printed fine enough to align directly with microcontroller pins and other electronic components, allowing components to be soldered directly to the printed conductor.

So now the structure can start doing more than carrying load.

It can carry power.
It can carry signals.
It can become part of the electronics system itself.

That is where additive manufacturing starts changing spacecraft architecture, not just spacecraft geometry.
