Top 1: University of Michigan Develops Software to Reduce Warping in Metal 3D Printing
One of the most persistent and significant challenges in metal 3D printing, particularly with processes like Laser Powder Bed Fusion (LPBF), is the phenomenon of part warping. This undesirable deformation occurs due to the extreme thermal gradients and residual stresses inherent in the layer-by-layer melting and solidification process. As metal powder is melted by a laser and then rapidly cools, differential contraction across the part can lead to internal stresses that cause the material to bend or distort, compromising dimensional accuracy and mechanical integrity. For industries where precision is paramount, such as aerospace, automotive, and biomedical, warping can render expensive parts unusable, leading to material waste, increased production costs, and extended lead times. Addressing this issue is crucial for the wider adoption and reliability of metal additive manufacturing.
In a significant step forward, researchers at the University of Michigan have unveiled a novel solution designed to mitigate this prevalent problem. Led by Chinedum Okwudire, an Associate Professor of Mechanical Engineering, the team has developed an innovative thermal-model-based software. This sophisticated program doesn’t just identify potential warping; it actively directs the printer’s lasers to follow an optimal scanning sequence. By strategically controlling the laser’s path and timing, the software aims to manage heat distribution more effectively during the printing process, thereby minimizing the thermal stresses that cause warpage. This intelligent approach promises to enhance the quality and reliability of metal 3D printed parts, making additive manufacturing a more robust and predictable process for high-value applications. The implications for critical components in advanced industries are immense, offering the potential for more consistent production and reduced post-processing efforts.

Top 2: FabRx is Pioneering Personalized 3D Printed Medicine
The concept of personalized medicine, tailoring medical treatment to the individual characteristics of each patient, is rapidly transforming healthcare. At the forefront of this revolution is 3D printing, offering unprecedented capabilities to create drugs designed for specific patient needs. In our recent 3D Interview, we had the privilege of speaking with Alvaro Goyanes, Co-Founder & CEO of FabRx, a company dedicated to advancing drug printing technologies. He shed light on the immense importance of these innovations for the future of pharmaceuticals and patient care. Traditional drug manufacturing often adheres to a “one-size-fits-all” approach, which may not be ideal for all patients, especially those with complex conditions, unique metabolisms, or those requiring multiple medications.
3D printed medicine addresses these limitations by allowing for precise control over dosage, drug combinations, and release profiles within a single pill. This technology enables the creation of “polypills” containing multiple active pharmaceutical ingredients, potentially improving patient adherence and simplifying complex medication regimens. Furthermore, 3D printing can produce drugs with novel geometries or textures, which can influence how the drug dissolves and is absorbed in the body, optimizing therapeutic effects. Alvaro detailed how FabRx is leveraging these capabilities to develop truly personalized medications, moving beyond the standard tablet to offer customized treatments. This level of customization can revolutionize care for vulnerable populations, such as pediatric patients who often require precise, smaller doses, or geriatric patients who might benefit from multi-drug pills to manage chronic conditions. The potential for on-demand drug manufacturing in hospitals or pharmacies could also reduce logistical complexities and improve access to specific medications. FabRx’s pioneering work is not just an academic exercise; it’s a tangible step towards a future where medicines are as unique as the individuals who take them, promising improved efficacy and fewer side effects.

Top 3: BCN3D Creates an Anatomically Correct Heart Using FDM Technology and TPU
The application of 3D printing in healthcare extends far beyond drug development, playing an increasingly vital role in medical education, surgical planning, and patient-specific treatments. One of the most impactful uses is the creation of anatomically accurate models, which provide an invaluable tool for students and seasoned surgeons alike to study complex human anatomy and practice intricate procedures before entering the operating room. These tangible models offer a level of detail and tactile feedback that traditional 2D images or virtual simulations cannot fully replicate, enhancing comprehension and preparedness. The ability to hold and manipulate a physical representation of a patient’s organ or a specific anatomical structure significantly aids in understanding complex pathologies and planning the most effective surgical approach.
While advanced 3D printing technologies often come to mind for such intricate medical models, BCN3D impressively demonstrates the capabilities of more accessible FDM (Fused Deposition Modeling) 3D printers and flexible materials. Their project showcases an anatomically correct heart printed using Thermoplastic Polyurethane (TPU) – specifically, 95A TPU – and BVOH (Butenediol Vinyl Alcohol Copolymer) for soluble supports. The choice of TPU is strategic: its flexibility mimics the soft tissues of organs, providing realistic haptic feedback crucial for surgical training. Furthermore, FDM technology, known for its cost-effectiveness and widespread availability, makes this type of medical model more accessible to institutions and smaller healthcare providers. The use of BVOH as a support material is also critical; being water-soluble, it can be easily washed away, leaving behind a clean, intricate model without damaging delicate internal structures like ventricles and chambers. This allows for the creation of highly detailed and functional models where the internal anatomy is perfectly preserved and visible. The resulting heart model vividly displays all the ventricles and chambers, offering an unparalleled learning and planning aid. This project underscores the versatility and growing impact of FDM 3D printing in advancing medical understanding and improving patient outcomes globally.
