Researchers at MIT have successfully created durable, interlocking glass bricks using 3D printing technology. These reusable bricks, which can withstand loads similar to concrete blocks, offer a promising sustainable alternative for future construction.

The engineers behind this innovation aim to promote a circular construction process by using recycled glass. The glass can be reshaped or repurposed at the end of a building’s life cycle, significantly reducing waste. In the future, these 3D-printed glass blocks could be used for building facades or interior walls, offering an eco-friendly substitute for traditional concrete.

Until now, printing living tissue constructs required specialized and expensive bioprinters. However, researchers from the Centre for Applied Tissue Engineering and Regenerative Medicine (CANTER) at Munich University of Applied Sciences have found a way to modify a simple, commercially available 3D printer to create biological structures at the touch of a button. This breakthrough opens up the field of bioprinting to smaller laboratories that previously couldn’t afford the specialized equipment.

Benedikt Kaufmann, a research associate at CANTER, led the team that developed this cost-effective solution. By modifying a standard 3D printer, they overcame a significant challenge in bioprinting: maintaining the right conditions for temperature and humidity. Using heating foils and water-soaked cellulose, the team achieved a stable environment of 37°C and over 90% humidity, crucial for printing biomaterials. The process takes place on a translucent glass platform, allowing for detailed microscopic examination of the printed structures.

Researchers at the University of Minnesota have developed a groundbreaking adaptive 3D printing system that can autonomously recognize and position randomly distributed organisms with precision. This innovative technology, a first of its kind, offers substantial benefits in fields such as bioimaging, cybernetics, cryopreservation, and the integration of living organisms into technical devices. The research findings, recently published in Advanced Science, have already led to a pending patent for the technology.

How the System Works

The system operates by detecting organisms, whether they are stationary, enclosed in droplets, or in motion, and accurately positioning them in designated locations. It employs a pick-and-place method that leverages real-time visual and spatial data to identify and safely place the organisms. This level of precision and adaptability is a significant improvement over traditional methods, which require manual intervention. Manual handling is not only time-consuming but can also result in inconsistent outcomes. The new system streamlines this process, reducing the time required for these tasks while ensuring consistent and reliable results.

At the University of Maine, a groundbreaking solution to the housing crisis is taking shape—literally. One of the world’s largest 3D printers is now using sawdust from the state’s lumber industry to create cozy, sustainable wooden cabins. This innovative approach aims to address Maine’s pressing need for affordable housing while promoting faster and more environmentally friendly construction methods.

The housing shortage in Maine mirrors a nationwide crisis, with an estimated 80,000 new homes needed over the next five years to meet growing demand. While traditional construction methods struggle to keep up, the technicians at the University of Maine’s Advanced Structures & Composites Center (ASCC) believe their cutting-edge technology can make a significant impact. The ASCC’s 3D printer, recognized by Guinness World Records as the world’s largest prototype polymer 3D printer, can produce a 600-square-foot house—96 feet long, 36 feet wide, and 18 feet tall—entirely out of bio-based materials at an astonishing rate of 500 pounds per hour.

The process of creating 3D-printed, patient-specific implants begins with a thorough clinical assessment to identify the unique needs of each patient. Advanced imaging techniques, such as X-rays and CT scans, are utilized to gather detailed anatomical data, which is then converted into a digital 3D model using specialized software. This digital model is sent to a 3D printer, where rigorous quality control measures ensure the implant is manufactured with precision and accuracy.

The implant is custom-designed to fit the patient perfectly, ensuring optimal functionality and comfort. The use of 3D printing allows for the replication of complex structures and intricate details that would be challenging to achieve with traditional manufacturing methods. This precise production process ensures that the implant meets the highest standards, leading to a successful surgical outcome and a swift recovery for the patient.

Engineers at the University of California, San Diego, have developed a groundbreaking 3D printing method that could significantly advance sustainable and environmentally friendly manufacturing. The innovative technique, detailed in Nature Communications, utilizes a polymer ink and a saltwater solution to create solid structures with remarkable simplicity.

The process revolves around a liquid polymer solution known as poly(N-isopropylacrylamide), or PNIPAM. When this ink is extruded through a needle into a calcium chloride salt solution, it immediately solidifies upon contact. This rapid transformation is driven by a phenomenon known as the “salting-out effect,” where the salt ions attract water molecules away from the polymer solution. The removal of water causes the hydrophobic polymer chains in the PNIPAM ink to densely aggregate, forming a solid structure.

Lung diseases claim millions of lives globally each year, with limited treatment options and inadequate animal models for research. Now, researchers have made a significant advancement by developing a mucus-based bioink for 3D printing lung tissue, as detailed in a study published in ACS Applied Bio Materials. This innovation holds promise for better understanding and treating chronic lung conditions.

While lung transplants offer a lifeline to some, the shortage of donor organs limits this option. Medications and treatments can manage symptoms of diseases like chronic obstructive pulmonary disease (COPD) and cystic fibrosis, but no cure exists. Traditional research methods using rodents often fall short in accurately replicating human pulmonary diseases and predicting drug safety and efficacy. In response, bioengineers are turning to lab-grown lung tissue, aiming to create more precise models or potential implant materials.
