Bioprinting and 3D Printing

Detailed overview of innovation with sample startups and prominent university research


What it is

Bioprinting and 3D printing with bio-based materials are revolutionizing manufacturing, offering a sustainable and innovative approach to creating complex structures and functional products. Bioprinting specifically refers to the 3D printing of living cells and biomaterials to create biological structures like tissues and organs. More broadly, 3D printing with bio-based materials utilizes renewable resources like plant-based polymers, algae extracts, and even fungal mycelium to fabricate a range of objects, from packaging to building components. This technology offers a compelling solution to reduce the environmental impact of traditional manufacturing, enabling on-demand production, minimizing waste, and utilizing renewable resources.

Impact on climate action

Bioprinting and 3D printing of bio-based materials offer a sustainable alternative to conventional manufacturing, reducing reliance on fossil fuels and minimizing carbon emissions. By enabling the production of biodegradable products and structures, this innovation promotes circular economy principles and contributes to mitigating climate change.

Underlying
Technology

  • 3D Printing Technologies: Bioprinting and 3D printing with bio-based materials utilize various 3D printing technologies, including:
    • Extrusion-Based Printing: A bio-based material, often in a paste or gel form, is extruded through a nozzle layer by layer to build a 3D object.
    • Vat Polymerization: A liquid photopolymer resin, containing bio-based components, is selectively cured by a light source, layer by layer, to form a 3D object.
    • Powder Bed Fusion: A laser or electron beam selectively melts and fuses powdered bio-based material, layer by layer, to create a solid object.
  • Bio-Ink Development: Bioprinting requires the development of specialized “bio-inks” that contain living cells, biomaterials, and growth factors. These bio-inks must be carefully formulated to support cell viability and functionality during the printing process and subsequent tissue development.
  • Material Science and Engineering: Optimizing the printability, mechanical properties, and biocompatibility of bio-based materials for 3D printing requires expertise in material science and engineering.
