The Geneva Foundation and the Uniformed Services University (USU) 4D Bio3 Program, in support of the U.S. Military, recently completed a pilot project involving the biofabrication of medical products in an austere military environment, with the goal of advancing future nextgeneration treatments for the Nation’s deployed warfighters. Advances in 3D printing and biofabrication have the potential to provide unprecedented benefits for the warfighter, including perhaps the direct repair or replacement of damaged tissues. This is especially powerful when achieved in austere conditions; warfighters injured in the field could have personalized health solutions immediately fabricated onsite.
The 4-Dimensional Bioprinting, Biofabrication, and Biomanufacturing Program (4D Bio3) is a federally funded program that advances the development and application of advanced bioprinting, biofabrication, and biomanufacturing technologies for research pursuant to Department of Defense (DoD) priorities and, ultimately, for translation to clinical medical defense care and training solutions. 4D Bio3 currently has several programmatic efforts in motion, one of which involves the recently accomplished advanced 3D printing activities in a forward-deployed desert environment. This initiative is part of the 4D Bio3 Fabrication in Austere Environments (Fab AE) Program and supports a proof-of-concept project demonstrating the feasibility of 3D printing a wide range of personalized health care products in remote geographic locations, notably austere environments.
This successful pilot project represents a multi-disciplinary collaboration which included nScrypt and RoosterBio,Inc. nScrypt’s bioprinter, called the Austere BioAssembly Tool (ABAT™), is a lightweight and ruggedized bioprinter that was custom designed by nScrypt based on their 3D printer experiences with the BioFabrication Facility on the International Space Station. The ABAT™ provides 3D printing solutions with a wide range of materials, including polymers, electronic components, and biologics.
Along with the printer, basic supplies and raw materials were transported to the austere environment, including RoosterBio’s Ready To Print (RTP) human mesenchymal stem/stromal cells (hMSCs); a first-of-its-kind product that was designed to radically simplify and standardize the most complex and labor intensive aspects of bioprinting. This technology enables austere printing in a resource-limited setting as these are the only cells that allow for same-day bioprinting capabilities. The forward-deployed printing project led onsite by LTC Jason Barnhill of the United States Military Academy West Point, Department of Chemistry and Life Science, resulted in the following biofabrication achievements:
- 3D printing of #3 scalpel handle and hemostat: The scalpel can fit a standard surgical blade and can be readily used and manipulated. The hemostat, a surgical tool used to control bleeding during surgery, is capable of gripping objects and can be locked in place to hold tissue or other medical implements. Individually, each surgical tool was printed within 1.5 hours. All printed surgical tools were capable of being steam sterilized onsite, reducing the chance of infection for practical use.
- 3D printing of bioactive bandages: These bandages were fabricated in a two-step process involving printing a hydrogel layer containing antibiotics over a flexible structural layer; all of which printed within five minutes. This design provides for slow release of antibiotics from the bandage into the wound site, resulting in prolonged bacterial suppression over several days. The bacterial suppression timeline and actual bandage design based on CT data can be tailored to fit need-based scenarios by altering antibiotic concentration and bioprinting parameters.
- 3D printing of a surgical model of T9 vertebrae: This model is based on de-identified image obtained from medical scans. A print-ready data file was electronically provided with the ABAT™ to the undisclosed location. Though not capable of patient implantation, this printed model will aid surgeons onsite in visualizing musculoskeletal injuries and determining the best course of medical intervention.
3D bioprinting of a meniscus: The bioprinted meniscus was comprised of live MSCs and a hydrogel scaffold. The RoosterBio RTP human bone marrow-derived hMSCs were taken directly from freezer to printer without the need for a dedicated cell culture environment. The file for the meniscus print was transmitted directly from a stateside facility to the remote environment, where it was printed on location. This is the first demonstration of cyber manufacturing being used whereby complex designs are transmittable to remote austere location for production.
This pilot project is a first step toward manufacturing health care products onsite potentially for treatment of battlefield injuries and medical conditions, shifting logistical needs from complete final products to material building blocks. Resulting military benefits include the potential to drastically reduce traditional supply chain and logistical challenges and costs of transporting medical supplies and related items providing both time and cost savings to the U.S. Military in resource limited settings. Perhaps equally important is the ability of 3D printing to provide personalized products to meet individualized warfighter needs.
