Scientists at Nanyang Technological University, Singapore (NTU Singapore) have pioneered a 3D concrete printing method that captures and stores carbon dioxide, marking a major step toward reducing the construction industry’s environmental footprint.

The innovative technique offers a promising solution to mitigate cement’s massive carbon emissions.

The process works by integrating CO₂ and steam—byproducts of industrial processes—into the concrete mix during 3D printing. As the material is printed, CO₂ reacts with components in the concrete, forming a solid, stable compound that remains locked within the structure.

Engineers at Johns Hopkins University have developed a new printing technique that solves for the fundamental weakness between the layers created during 3D printing. New printing technique allows them to precisely control interfaces between voxels, the three-dimensional counterparts to pixels, and how they function.

A 21-year-old Edmontonian is developing a 3D printer designed to take soil from the moon and convert it into essential equipment for astronauts.

Madison Feehan, CEO and founder of Space Copy, said she realized that 3D printing could substantially reduce the significant cost and logistic hurdles of sending astronauts back to the moon during her five years as a contract worker for NASA.

Radio Active’s Min Dhariwal spoke with Feehan this week to learn more about her research.

Yongcui Mi has developed a new technology that enables real-time shaping and control of laser beams for laser welding and directed energy deposition using laser and wire. The innovation is based on the same mirror technology used in advanced telescopes for astronomy.

In a few years, this new technology could lead to more efficient and reliable ways of using high-power lasers for welding and directed energy deposition with laser and wire. The manufacturing industry could benefit from new opportunities to build more robust processes that meet stringent quality standards.

“We are the first to use deformable mirror technology for this application. The mirror optics can handle multi-kilowatt laser power, and with the help of computer vision and AI, the laser beam can be shaped in real time to adapt to variations in joint gaps,” explains Yongcui, a newly minted Ph.D. in Production technology from University West.

Electrostatic discharge (ESD) protection is a significant concern in the chemical and electronics industries. In electronics, ESD often causes integrated circuit failures due to rapid voltage and current discharges from charged objects, such as human fingers or tools.

With the help of 3D printing techniques, researchers at Lawrence Livermore National Laboratory (LLNL) are “packaging” electronics with printable elastomeric silicone foams to provide both mechanical and electrical protection of sensitive components. Without suitable protection, substantial equipment and component failures may occur, leading to increased costs and potential workplace injuries. The team’s research is featured in ACS Applied Materials & Interfaces.

3D printing is a rapidly growing manufacturing method that enables the production of cellular foams with customizable pore architectures to achieve compressive mechanical properties that can be tailored to minimize permanent deformation by evenly distributing stress throughout the printed architecture.

Researchers at the University of Twente, Netherlands, have made an advancement in bioprinting technology that could transform how we create vascularized tissues. Their innovative bioink, recently featured in Advanced Healthcare Materials, introduces a way to precisely guide the growth and organization of tiny blood vessels within 3D-bioprinted tissues. The tiny blood vessels mimic the intricate networks found in the human body.

3D-printed organs have the potential to revolutionize medicine by providing solutions for organ failure, and tissue damage and developing new therapies. But a major challenge is ensuring these printed tissues receive enough nutrients and oxygen, which is critical for their survival and function. Without blood vessels, these tissues can’t efficiently obtain nutrients or remove waste, limiting their effectiveness. Therefore, the ability to 3D-bioprint blood vessels is a crucial advancement.

Tissue engineers could already position blood vessels during the bioprinting process, but these vessels often remodel unpredictably when cultured in the lab or implanted in the body, reducing the effectiveness of the engineered tissue. The programmable bioink developed by the University of Twente team addresses this issue by providing dynamic control over vessel growth and remodeling over time. This opens new possibilities for creating engineered tissues with long-term functionality and adaptability.

Biomedical engineers from the University of Melbourne have invented a 3D printing system, or bioprinter, capable of fabricating structures that closely mimic the diverse tissues in the human body, from soft brain tissue to harder materials like cartilage and bone.

This cutting-edge technology offers cancer researchers an advanced tool for replicating specific organs and tissues, significantly improving the potential to predict and develop new pharmaceutical therapies. This would pave the way for more advanced and ethical drug discovery by reducing the need for animal testing.

Head of the Collins BioMicrosystems Laboratory at the University of Melbourne, Associate Professor David Collins said: In addition to drastically improving print speed, our approach enables a degree of cell positioning within printed tissues. Incorrect cell positioning is a big reason most 3D bioprinters fail to produce structures that accurately represent human tissue.
