Bioprinting. Bioprinting continues to dominate the conversation with advancements in reproductive medicine, organ-scale tissue engineering, and sustainable biomaterials. At the University of Nevada Reno School of Medicine, researchers have successfully bioprinted a uterus. This achievement, led by Professor Heather Birkin, is the result of nearly a decade of work. The model replicates the human uterus at the end of pregnancy, enabling drug testing for preterm labor without the need for human subjects. The team is now developing personalized versions tailored to specific risk factors, aiming to revolutionize treatments for preterm births. This work, published in October 2025, marks a significant step toward personalized reproductive health care. In Europe, the ENLIGHT project is working on bioprinting a functional pancreas. This €3.6 million euros initiative, supported by institutions like ETH Zurich, EPFL, and AstraZeneca, uses Rousselo's X Pure Gelatin Bioinks to create living pancreatic models for diabetes drug testing. Key innovations include a suspension medium that eliminates temperature control requirements, volumetric bioprinting that cures in under a minute, and cell-laden gels that remain viable for up to 21 days. The project's long-term goal is to develop patient-specific tissues using stem cells, potentially transforming organ transplantation. Berlin-Boston-based Cellbricks therapeutics raised 10 million euros to advance vascularized adipose tissue implants. These implants, which include built-in blood vessel networks, address the historically challenging problem of vascularization in tissue engineering. Targeting applications like soft tissue repair and breast reconstruction, this innovation offers a biological alternative to synthetic implants. The funding, supported by Silicon Roundabout Ventures and Germany's SPRIND, will help bring these implants closer to clinical trials. Singapore has also taken a leadership role in bioprinting with the publication of a national biofabrication roadmap. This comprehensive review highlights the use of sustainable biomaterials, such as hair keratin and fish collagen, and advanced technologies like 3D bioprinting. A standout feature of the roadmap is the focus on waste streams as inputs for clinical grade biomaterials, promoting a circular bioeconomy model. In Japan, Topin Holdings has developed a bioink platform to 3D print marbled cultured meat. Using collagen microfibers, this method replicates realistic fat marbling in meat, with potential applications extending to personalized medicine. This innovation, developed in collaboration with Osaka University, recently won a National Research Award, signaling its significance in both food production and medical fields.

FDA clearances and surgical implants. March was a strong month for FDA clearances, with new devices moving into operating rooms and advancing patient care. Spinal elements received FDA 510K clearance for the Ventana AALIF, an additively manufactured titanium spinal implant. Its hinged structure maximizes bone graft volume while reducing implant density, improving load sharing and lowering subsidence risk. The first clinical cases have already been performed at Texas Spine Consultants and the Spine Institute of Arizona, marking a significant milestone for titanium additive manufacturing in spinal surgery. A new review in Curious explored the design of 3D printed lumbar interbody cages. The review covered materials like peak and porous metals, as well as emerging innovations such as bioactive coatings. These advancements aim to improve biomechanics and patient outcomes in spinal surgery. 3D systems achieved full EUMDR certification for its next dent-jetted denture solution. Following its U.S. launch in 2025, the company plans to enter the European market by summer 2026. With 180 million denture wearers worldwide and a $400 million potential recurring materials revenue, this product has the potential to transform the dental industry.

Oncology and Cancer Research. 3D printing is also making significant contributions to oncology, particularly in cancer research and surgical precision. Cairn Surgical filed a de novo 510K submission with the FDA for its breast cancer locator. This 3D printed surgical guide addresses a critical issue. Conventional imaging often underestimates tumor size, leading to incomplete tumor removal and repeat surgeries. Cairn's system uses supine MRI to create a patient-specific guide, providing surgeons with precise tumor dimensions and locations. Clinical data shows a 94% negative margin rate, with full trial results expected to be presented at the American Society of Breast Surgeons in April. Rice University has developed Atlas, a 3D printed platform for studying cancer metastasis. This system uses superhydrophobic microwell arrays to generate scalable cancer cell clusters that replicate bloodstream conditions. Researchers discovered that cancer-associated fibroblasts shield metastatic clusters from blood flow stress. This finding could lead to new treatments targeting these fibroblasts to prevent metastasis with commercialization efforts underway through a startup called Bionnostic.

Robotics and Advanced Manufacturing. Cutting-edge developments in robotics and advanced manufacturing are pushing the boundaries of 3D printing technology. Leiden University has created microrobots that swim without brains, sensors, or software. These five micrometer-long robots navigate obstacles and steer away from each other through their flexible, chain-like shape. Potential applications include targeted drug delivery and minimally invasive procedures at cellular scales. The University of Central Florida received a DARPA grant to develop AI-powered quality control for additive manufacturing. This machine learning model predicts defects and mechanical performance, replacing costly and destructive testing cycles for titanium parts. With potential applications in aerospace, healthcare, and automotive industries, this innovation could significantly reduce production costs. UNIST has demonstrated droplet-based volumetric 3D printing for cereal production. This method uses photocurable resin cured within suspended droplets, enabling the production of 10 different objects in just 10 minutes. An AI framework ensures real-time shape detection, making this technology a potential game changer for continuous manufacturing. Boston Microfabrication launched the MicroArch S150, a high-resolution 3D printer designed for microfluidics, drug delivery devices, and surgical tools. This system offers sub-25 micrometer resolution, setting a new standard for precision at the micro scale.
