  1. 3D-Printed Living Material with CO₂ Capture

    • Researchers at ETH Zurich developed a printable hydrogel containing cyanobacteria – photosynthetic microbes that take in CO₂ and convert it into biomass and mineral carbonates.
    • That material can be shaped (printed) and then continues “growing” / binding CO₂ over time. However, it’s not quite “printing with carbon vapor” in the sense of using ambient CO₂ as the direct material for building solid parts. It’s more biologically assisted sequestration within a structural matrix.

  2. 3D-Concrete Printing with CO₂ Injection

    • At Nanyang Technological University (NTU), scientists have developed a 3D concrete printing method that injects CO₂ (and steam) into the concrete mix as it’s printed. The CO₂ reacts chemically and becomes locked in the concrete, thus both building structure and sequestering carbon.
    • This is promising and closer to what you described. But note: the CO₂ is captured elsewhere or from industrial byproducts, then injected. It’s not passively drawn from ambient air in large amounts. Also, the material is concrete, not fine detailed polymer or composite structures.

  3. Resin that Captures CO₂ During Use

    • A company called 3Dresyn developed a resin “3Dresyn CDC1” for SLA/DLP/LCD printing. This resin formulation contains hydrated lime, which absorbs CO₂ from air and then forms calcium carbonate (limestone) as it cures.
    • So here the printing material itself has a function of absorbing CO₂ during its life / curing. But again: it doesn’t manufacture itself from atmospheric vapor alone; it’s just a material additive/feature.

  4. Other Carbon Capture + Utilization / DAC + Conversion Research

    • There are many projects in direct air capture (DAC), converting CO₂ into useful chemicals, fuels, or polymers. Some of these are early stage. But turning ambient CO₂ directly into usable filament or structural material suitable for high resolution 3D printing, in a self-contained printer, is not something I found real world evidence for.
    • For example, “Direct Air Electrowinning” is a process in research that captures CO₂ from air and converts it electrochemically into chemicals.

Open Challenges & What Would Be Needed

To have a printer that “prints material using carbon vapor from the atmosphere,” you would need to integrate several difficult technologies:

  • Efficient direct air capture (DAC): getting CO₂ from ambient air at a scale, with low energy overhead. Air is ~0.04% CO₂, so capturing enough for material needs is tough.

  • Conversion chemistry: Once you have CO₂, need to convert it into a usable form (polymer monomers, carbonate binders, etc.). That often requires catalysts, energy (heat, electricity, light), and/ or additional reagents.

  • Material formation / deposition: The form you produce (resin, concrete mix, filament, etc.) must be compatible with 3D printing, and have the right mechanical / structural properties.

  • Energy efficiency & sustainability: The process mustn’t consume more energy or create more emissions than it saves, or else it loses the benefit.

  • Cost & scaling: Making all the above feasible, affordable, durable etc.

Conclusion — Is “Atmosphere Carbon 3D Printer” Viable Today?

  • Not yet as a mature commercial product — I didn’t find proof of a printer that literally uses only carbon vapor from the ambient air, performs all capture + conversion + printing in one machine, and produces finished objects comparable to normal 3D printed parts.

  • Parts of it are happening — materials that absorb CO₂, concrete that locks CO₂, living materials, etc. So the idea is in active R&D and could become viable in some form.
