WHAT IF 3D PRINTERS WERE OPEN AND FLEXIBLE?

← Swipe to explore branches →

We didn't want to build just another 3D printer. We wanted to build an instrument of curiosity.

3D Printers Were Enclosed

At the time, 3D printers were closed systems. Literally and figuratively.

They were boxes—enclosed, proprietary, single-purpose. If something broke, you couldn't fix it yourself. You had to send it back to the manufacturer and wait for a replacement part. The internals were hidden.

What if 3D printers were open? What if they weren't proprietary? What if they were more open?

Nothing Hidden

We thought, what if we didn't hide anything? What if every screw was visible, every wire was accessible, every component was understandable?
No proprietary brackets. No prescribed use cases. No right answer.
Just an open platform and your imagination.

From Concept to Reality

What if it was more than just a 3D printer?

What if it was an Instrument?

3D printers normally extrude plastic layer by layer, but at their core they’re really just precise machines that move back and forth, up and down. So why limit them to only extruding? What if the toolhead was modular? What if you could take it off and replace it with a rotary tool? What if the printer could print on an array of materials beyond the build plate?
What if you could take the extruder off and hand the robot a pen? What if you replaced the extruder with a spindle? What if you could put fabric on the build platform and print directly onto it?
Questions we asked
We obsessed over the quality because if people are going to modify and push our tool, it has to be built to withstand that exploration.

Built To Last

All-metal construction. Aerospace-grade aluminum and premium carbon steel. No plastic structural components that would flex or fail.

Million-motion cables. We tested them. Actually tested them—over one million motions. They're rated for thousands of hours of reliable operation because your experiments shouldn't be limited by our shortcuts.

Silent Trinamic stepper drivers. Four of them. Near-silent operation. Big ideas don't have to be loud.

The Spin N Select Knob. Perfectly knurled. Tactile. Satisfying. We went through seven prototypes to get it right. Because starting a print should feel good.

Buildini Built Like An Instrument

How Customers Used the Buildini

What an Instrument Taught Us

We started with a question: What if 3D printers were open and flexible? We learned:
Proprietary Systems Create Dependency

Proprietary Systems Create Dependency

True flexibility means people don't need our permission to experiment.

Transparency Invites Innovation

Transparency Invites Innovation

When every component is visible and accessible, users understand how it works. Understanding breeds modification. Modification breeds discovery. Discovery breeds applications you never designed for.

Quality Enables Exploration

Quality Enables Exploration

Cheap components would have limited experimentation. Million-motion cables, aerospace aluminum, silent drivers—quality isn't luxury when people are pushing your tool in unexpected directions. It's infrastructure for discovery.

The Buildini proved that 3D printers don't have to be appliances. They can be instruments. And instruments invite questions, not answers.

The Buildini led to bigger questions.

What Came Next

Watching people push the Buildini taught us what mattered: precision motion, build quality, and radical openness.

Those insights led us to ask a bigger question: What if we could print furniture?

The Progress printer—our large-scale furniture printer—evolved from everything the Buildini taught us. Same philosophy of openness. Same obsession with quality. Just... bigger.

The Buildini was the question that led to bigger questions.

There's no right way to use an instrument. Just your way.

Interested in Tools That Invite Questions?

The Buildini taught us that openness isn't just a feature—it's a philosophy. That philosophy continues to shape everything we build.
We built an open instrument. Users taught us what it could be. Those lessons led us to ask: What else can we build?
