Biopixlar is a completely new type of bioprinter with the unique capability to position cells in three dimensions with high resolution and precision without the use of bioink.

Based on innovative Fluicell technology, Biopixlar is capable of generating detailed, multi-cellular biological tissues, directly in cell culture media.

Biopixlar is all-in-one discovery platform that will help researchers around the globe to build biological tissues for drug development, disease understanding and regenerative medicine research.

  • Single-cell resolution

Design your biological tissue by printing down to the level of individual cells.

  • High-precision and reproducibility

Structure your biological tissue by precisely controlling the spatial deposition of your living cells and benefit from high reproducibility across replicates.

  • >95 % cell viability

The printing process is optimized to minimize the shear forces on the cell sample, achieving very high cell viability (cell viability was tested across multiple cell lines).

  • Multi-cellular models

Compose your biological tissue by printing up to three different cell types from the same print-head. By changing the printhead, new cell types can be printed.

  • Real-time monitoring

Follow your printing process in real-time with the fully integrated multi-color fluorescence imaging setup.

  • Ideal for valuable cell sources

Biopixlar is designed for handling scarce and valuable cell sources such as stem cells, primary cells and patient biopsies.


The Biopixlar platform consists of a bioprinter, a software, a gamepad, all situated on an optical table.

The platform contains:

1- Bioprinter

The bioprinter includes a micromanipulator arm and a motorized stage that let you precisely position the printhead and the sample. The printhead, based on innovative Fluicell microfluidic technology, is capable of printing several different cell types. The consumable printhead is made from a medical-grade elastomer and includes wells for containing cell suspension, reactant solutions and for collecting waste. The holder is a sophisticated pressure manifold that ensures a closed system, connecting the microfluidic printhead with a precision pressure controller.

The onboard multi-color fluorescence imaging setup allows real-time monitoring of your printing process and post-print analysis. The Biopixlar bioprinter additionally includes built-in environmental air-flow control, printhead heating, illumination of both the full chamber and the surrounding of the printing area, and optional UV light sterilization.

2- Software with gamepad interface

The Biopixlar software enables easy configuration of the bioprinting process and intuitive use of the bioprinter. Through the software, positioning of the printhead can be controlled, as well as cell type, deposition mode, and printing rate. The environmental controls can also be adjusted.

Biopixlar has the capability of bringing complex geometries in an automated or manual manner. The gamepad interface brings an entirely new way to experience bioprinting by putting full control of the process in the palm of your hand. With the gamepad, you have the ability to e.g. position the printhead, and deposit cells with the press of a button. A graphical user interface is also included for design of simple 2D structures.


With our microfluidic technology, the printhead enables direct cell patterning and printing, ranging from arrays of single cells to complex multi-cellular motifs.

Advance your science with relevant models

Biopixlar is designed for:

  • Producing  human-like tissue replicas
  • Understanding of specific diseases
  • Testing of drug compounds
  • Translating new therapies and technologies to patient

Luiz E. Bertassoni, DDS PhD,
Center for Regenerative Medicine and Department of Biomedical Engineering at OHSU School of Medicine:

“Function in the human body is dependent upon the close interaction of several million cells organized on microscale patterns in three-dimensions (3D). While the field of 3D bioprinting has enabled patterning of cells and biological materials with microscale precision, existing methods have been virtually unable to replicate the true complexity of native human tissues and organs. That is because, human tissues, by definition, have complex microscale morphologies and variable cellular compositions, and the spatial distribution of cells at the single cellular level is what determines function, and virtually no bioprinter has been able to achieve that.  

Fluicell’s technology is the first of its kind to enable single-cell resolution bioprinting with precision, speed and reproducible accuracy, even in 3D, in a way that was not possible before. This technology certainly provides a new tool for tissue engineers and biologists to mimic the complex geometric patterns and multi-cellular microenvironments that are characteristic to native human organs, and is important stepping stone for the field.”
