Researchers at the University of New Mexico’s Gerald May Department of Civil, Construction, and Environmental Engineering have developed an innovative material that could transform the future of construction and infrastructure maintenance. The material, a self-reinforced ultra-ductile cementitious substance, was designed specifically for 3D printing concrete structures, offering enhanced resilience and reduced reliance on traditional reinforcement methods. This breakthrough is poised to make concrete structures stronger, more flexible, and more durable—ultimately improving the lifespan and cost-effectiveness of public infrastructure.

Traditional construction processes often involve heavy machinery, steel beams, and manual labor, which can be expensive and dangerous. Additionally, maintaining concrete structures is an ongoing challenge due to the material’s brittleness and tendency to crack under tension. Even reinforced concrete, which is commonly used for buildings, bridges, and sidewalks, requires continuous repairs.

A research team from the National Institute for Materials Science (NIMS) has achieved a significant advancement in heat-resistant steel by using laser powder bed fusion (LPBF)—a type of metal 3D printing.

The team fabricated test specimens and subjected them to creep testing for up to 10,000 hours, revealing that LPBF significantly extended the creep life of the material, achieving at least a 10-fold increase compared to steel produced through traditional heat-treatment processes. These groundbreaking findings are detailed in the journal Additive Manufacturing.

LPBF is an additive manufacturing technique where metal powder is deposited and selectively melted layer by layer using a high-powered laser, eventually forming solid 3D metal components. Unlike conventional manufacturing methods, LPBF can create complex shapes with more precision, and it has seen applications across various industries. However, ensuring that LPBF-produced materials can withstand high-temperature, high-pressure environments over extended periods is crucial, especially for safety-critical applications like thermal power plants.

In an exciting breakthrough, researchers at Empa have developed a 3D-printed, biodegradable fungal battery that generates electricity in a completely unique way—by “feeding” on nutrients rather than being charged. This innovative technology has the potential to power sensors for agricultural applications or research in remote areas. Once its job is done, the battery digests itself from the inside, making it completely non-toxic and environmentally friendly. The study, which details this novel development, was published in ACS Sustainable Chemistry & Engineering.

Fungi, a diverse group of organisms more closely related to animals than plants, are already known for their wide range of uses—from providing food and medicine to producing pathogens. Now, Empa researchers have unlocked a new capability: fungi that generate electricity. This achievement is the result of a three-year research project led by scientists at Empa’s Cellulose and Wood Materials Laboratory.

In a groundbreaking development, researchers have harnessed the power of low-cost FDM 3D printing technology to create scaffolds that closely mimic the mineral properties of natural bone tissue. By combining poly(lactic-co-glycolic acid) (PLGA) with hydroxyapatite (HA), they’ve created a base structure that offers a realistic environment for bone research. This innovative method significantly lowers the barrier to entry for labs, as it eliminates the need for expensive bioprinters traditionally required for such work.

While high-end bioprinters can cost hundreds of thousands of dollars, this new technique shows that even inexpensive desktop 3D printers can be used to produce functional scaffolds that are suitable for complex biomedical research. This democratization of technology could allow a wider range of labs, especially those with limited funding, to engage in advanced bone tissue research.
