Biology,
Manufactured.

Printr Bio engineers cells and materials together, so living systems can run inside real hardware without destroying it, or being destroyed by it.

Our first system is a closed-loop perfusion platform designed for stable operation where living tissue meets synthetic hardware.

Bioloop

Codename · subject to change

A closed-loop platform that keeps living tissue oxygenated, fed and stable for long runs, with a defined output port for whatever it’s feeding.

Where living tissue meets synthetic hardware, the interface often becomes the limiting factor. BioLoop co-designs the living and mechanical components to reduce interface-driven failure and extend stable operation.

[02] InterfacePB-INT / Mechanical + living

Both sides of the surface.

Every living system running on hardware hits the same wall: the interface where the two touch. Adsorption, activation and fouling accumulate until performance falls away.

We co-design the biological and mechanical interface rather than optimizing either side in isolation.

[03] ApplicationsPB-APP / Where the loop connects

Where the loop connects first.

APP-01Lead

Ex vivo organ perfusion

Keeping organs viable outside the body, on a circuit engineered to work with living tissue instead of against it.

APP-02Target

Organoid culture

Continuous supply for organoids that grow larger, live longer and behave more consistently, run after run.

APP-03Target

Biocompute

Living processors need life support that runs for months and a surface that doesn’t foul the electrodes. Both are unsolved.

[--] ProcessPB-MFG / Cell to circuit

  1. Engineer

    Co-design cells and materials as a single system.

  2. Expand

  4. Run

    Sustain the living system in a closed loop.

  5. Verify

    Check every batch against spec before it ships.
