3DN: 3DBiotech is actively involved in projects related to regenerative medicine. Could you elaborate on these initiatives?

Within the vast spectrum of possibilities that bioprinting offers in the exciting field of regenerative medicine, our initial strategic approach is concentrated on the dental sector. This is a deliberate choice, as the dental sector is where we hold a leadership position and possess a robust foundation that allows us to effectively introduce and integrate novel technologies and advanced procedures. This focused approach specifically involves applying regenerative medicine principles to the critical areas of bone tissue and gingival mucosa regeneration. These two areas represent significant challenges in modern dentistry. For instance, low bone density often complicates or even prevents the successful placement of dental implants, impacting numerous patients. Concurrently, the retraction or loss of gum tissue, frequently caused by various pathologies, can lead to severe aesthetic concerns and significant health problems for individuals. By addressing these issues with bioprinting-based regenerative solutions, we aim to dramatically improve patient outcomes, restore natural function, and enhance quality of life, solidifying our commitment to advancing personalized dental care.

3DN: You currently offer your 3D BIOLOGIC MOD-101 bioprinter. Could you provide more details about its technologies and the biomaterials it supports?

Our 3D BIOLOGIC MOD-101 bioprinter is nearing the final stages of development, with us meticulously refining the last details and functionalities of the prototype before its commercial launch. This device is engineered to incorporate many of the sophisticated features typically found in high-tech, top-tier models within this advanced field.

This strategic approach is designed to facilitate its rapid adoption by a broad range of stakeholders and researchers keenly interested in leveraging this powerful technology for their work. Regarding biological materials, our bioprinter boasts extensive versatility, covering the entire spectrum of materials relevant to bioprinting applications. This includes both traditional thermoplastic materials such as PLA (Polylactic Acid), PLC (Poly(L-lactide-co-caprolactone)), and high-performance polymers like PEEK (Polyether Ether Ketone), which are valued for their mechanical properties and biocompatibility. Furthermore, it excels with various biomaterials available in hydrogel formats, including natural components like collagen and chitosan, as well as nanocellulose and alginate. This comprehensive material compatibility ensures that we can effectively supply our users with all the necessary resources and options to meet the diverse and evolving requirements of their groundbreaking research and developmental projects.

3DN: In your expert opinion, what are the most significant benefits of tissue bioprinting for personalized medicine?

The primary and perhaps most transformative advantage that tissue bioprinting brings to personalized medicine is its ability to mitigate or entirely prevent the risk of rejection once a bioprinted biological structure has been implanted into a patient. This is because the structures can often be created using the patient’s own cells, leading to the body recognizing the implant as “self” rather than a foreign object, thereby circumventing adverse immunological responses that are common with traditional transplants. Beyond this crucial benefit, bioprinting empowers us with unparalleled design capabilities through CAD (Computer-Aided Design) software. This allows us to meticulously design and construct biological structures that are astonishingly similar, in both form and function, to those created naturally by the human body. The ability to build these complex biological tissues and organs *ex vivo* (outside the human body) offers a controlled environment for their development. Furthermore, this technology facilitates the achievement of a highly homogeneous distribution and precise alignment of cells within the newly created tissue, factors that are absolutely vital for the successful integration, functionality, and long-term viability of the engineered tissue once implanted. This level of customization and control is simply unattainable through conventional medical approaches.

3DN: How do you envision the future of additive manufacturing within the medical sector?

I believe that additive manufacturing already holds a substantial and growing presence within the medical sector here in Spain, and its future is poised for even greater expansion, particularly with the anticipated widespread implementation of bioprinting technologies in our hospitals and clinics. However, for this vision to fully materialize, we still have several stages to navigate, including regulatory approvals, infrastructure development, and comprehensive training. At 3DBiotech, we are keenly aware that our long-term vision must be forward-thinking, guiding us towards an innovative future, yet without losing sight of our present realities and immediate opportunities. This dual focus is crucial. That’s precisely why we are concurrently developing two projects with immediate, practical applications that are already making a tangible impact on the use of additive manufacturing within the medical and hospital sectors across Spain.
