3D Bioprinting: Market Trends and Innovations

3D bioprinting has significant potential in tissue engineering, the artificial development of tissues and organs for implantation, and the creation of tissue and organ models for pharmaceutical and toxicological research.1 This article explores recent innovations that have advanced the 3D bioprinting field.

What is 3D Bioprinting?

The rapid advancement of 3D bioprinting technology has revolutionized surgery, medicine, and dentistry. It allows for the creation of customized artificial implants and prosthetics tailored to individual patient preferences or specific surgical requirements.2

Tissue and organ damage is a major medical issue arising from aging, illness, trauma, and genetic conditions. Organ transplants from living or deceased donors have been the primary treatment, but there is a severe shortage of donor organs, exacerbated by the increasing number of recipients.

Organ transplants often face rejection by the recipient’s body. Researchers have turned to 3D bioprinting, which uses a patient’s genetic material to generate replacement organs. This personalized approach reduces the risk of rejection and eliminates the need for lifelong immunosuppressive medications.3

Moreover, bioprinting technologies support personalized medicine by manufacturing 3D organ cultures for various purposes. These cultures are crucial in drug development and toxicity testing, allowing researchers to observe tissue and disease formation and progression in controlled environments.4

Among the many advantages of 3D bioprinting, reproducing the complexities of body physiology in vitro is particularly promising. This capability opens new horizons for personalized medicine, enabling more customized implants and better drugs for individual patients.5

Current Market Trends in 3D Bioprinting

In the past five years, innovative 3D printing technology has led to the emergence of 3D bioprinting. The market size is estimated at 2 billion U. S. dollars.6 Recent technological innovations have significantly reduced the time required for bioprinting tissues and organs, leading to substantial revenue growth.

The research and commercial sectors have become significantly interested in 3D bioprinting, with substantial global investments. Market specialists expect a nearly 12 % increase in market value.

According to the “Technology Foresight Tool,” the number of 3D bioprinting patents has grown significantly from 2015 to 2023, totaling 2,868. Additionally, 24 new companies joined the patent race last year, bringing the total to 121 companies, indicating a growing focus and investment in advancing bioprinting technologies.

Key Innovations Shaping the Future of 3D Bioprinting

The University of Wisconsin–Madison has created the first 3D brain tissue that can grow and function like natural brain tissue. This discovery provides hope for treatments for neurological and neurodevelopmental disorders, including Alzheimer’s and Parkinson’s diseases.8

L’Oréal’s Advanced Research team, in collaboration with the University of Oregon, has developed an artificial skin model closely matching human skin using 3D bioprinting.9 This innovation involved using melt electro-writing (MEW) to produce plastic scaffolds that mimic the extracellular matrix of natural skin.

3D bioprinting is also proving to be crucial in cancer research, playing a key role in combating dangerous diseases.

Challenges Limiting Wider Adoption

Selecting optimal biological materials that will not trigger immune rejection is crucial in 3D bioprinting. However, finding the right bioinks and scaffold materials remains challenging. Ensuring the survival and adjustment of embedded cells during the bioprinting process is essential, but this does not always happen, leading to damage and delays.

The created structures must remain stable and interact safely with surrounding tissues to avoid infection. Efforts are ongoing to ensure these structures are biocompatible, stable, and long-lasting.10 Public awareness and education are needed to address ethical concerns and confusion regarding bio-printed tissues.

The Future of 3D Bioprinting

The impact of 3D bioprinting technology on medicine and surgery is profound.

Recently, 4D printing has gained attention for its ability to create objects that reshape themselves, particularly shape-memory materials. These techniques offer applications in neural regeneration, drug screening, and disease modeling. They also hold promise for personalized diagnostics and precise therapeutic approaches for conditions like brain cancers.11

The potential of 3D to 6D printing offers exciting opportunities, marking a significant advancement in the field and fully unlocking the potential of bioprinting technology.
