US scientists develop 3D printing method that could reshape body armor
Researchers at The University of Texas at Austin and Sandia National Laboratories have developed a novel 3D printing technique called Crystallinity Regulation in Additive Fabrication of Thermoplastics (CRAFT). This method enables the creation of 3D objects with varying mechanical and optical properties—such as hardness and transparency—at the pixel level using a single, inexpensive material, cyclooctene resin. By precisely controlling light intensity during printing, the team can manipulate the molecular order of the material as it solidifies, allowing different parts of an object to have distinct textures and properties within a single piece. For example, they successfully printed a realistic human hand model that mimics the textures of skin, ligaments, tendons, and bone, offering a superior alternative to cadavers for medical training. CRAFT’s ability to produce seamless transitions between hard and soft regions addresses a common limitation in existing multi-material 3D printing, which often suffers from weak bonding at joints. Beyond medical applications, the technique

Researchers at Oak Ridge National Laboratory (ORNL) have developed a novel extrusion system for large-scale 3D printing that merges multiple smaller extruders into a single high-output material stream using specially engineered nozzles. This innovation overcomes a key tradeoff in extrusion-based additive manufacturing: large extruders provide high volume but reduce precision and add weight, while smaller extruders offer control but lack scalability. ORNL’s modular system allows users to activate or deactivate extruders as needed, scaling output without sacrificing accuracy or increasing the mechanical burden on motion systems. A standout feature of the technology is its ability to print multiple materials simultaneously within a single extrusion bead, eliminating the need for tool changes or separate print passes. This is achieved through patent-pending aluminum bronze nozzle blocks with Y-shaped internal channels that merge molten polymer streams, improving bead quality and doubling material flow. Additionally, a proprietary nozzle design enables core-and-sheath bead structures, combining different polymers to enhance mechanical properties and interlayer adhesion, addressing common

The UK has made a significant advancement toward its goal of operating a prototype fusion power plant by 2040 through the launch of DIADEM, a research initiative focused on overcoming a major materials engineering challenge. Fusion reactors require components that can withstand extreme heat—up to 3,000°C—and intense magnetic fields. Tungsten and copper are ideal materials for these conditions due to tungsten’s high melting point and copper’s excellent heat conduction. However, their vastly different melting points and thermal expansion rates have made traditional joining methods like welding or casting ineffective, often resulting in cracks or separation. DIADEM, led by the University of Nottingham’s Centre for Additive Manufacturing, is addressing this by using Multi-Metal Laser Powder Bed Fusion (MM-LPBF), an advanced 3D printing technique that simultaneously fabricates tungsten-copper components from the ground up. This process creates “metamaterials” with a smooth microscopic transition between the two metals, eliminating weak seams and improving durability. This breakthrough not only advances

Researchers at Virginia Tech have developed a novel 3D-printed smart composite that enables traditionally brittle ceramics to bend, absorb energy, and endure heavy mechanical loads without cracking. Led by Associate Professor Hang Yu, the team embedded tiny shape-memory ceramic particles into metal using a solid-state additive friction stir deposition (AFSC) process, which fuses materials below their melting point under intense pressure. This approach produces a strong, defect-free composite that can undergo stress-induced phase transformations to dissipate energy, allowing the material to withstand tension, bending, and compression while maintaining full density in bulk form. This breakthrough overcomes a longstanding challenge in materials science, as shape-memory ceramics previously only functioned at microscopic scales due to their tendency to fracture when produced in bulk. The new composite’s multifunctionality and scalability open up promising applications across defense, aerospace, infrastructure, and high-performance sporting equipment, such as vibration damping in golf club shafts. Supported by the National Science Foundation and the US Army Research Laboratory, the research highlights

Scientists at Idaho National Laboratory (INL) are pioneering a novel approach to nuclear fuel design by drawing inspiration from nature’s mathematics, specifically triply periodic minimal surfaces (TPMS). These complex, repeating lattice structures, found naturally in butterfly wings and sea urchin shells, offer highly efficient geometries that can enhance heat transfer in nuclear fuel. INL’s concept, called the Intertwined Nuclear Fuel Lattice for Uprated heat eXchange (INFLUX), replaces traditional solid cylindrical fuel rods with a TPMS-based lattice. This design increases surface area contact with coolant, enabling more efficient heat removal and potentially leading to safer, more compact, and higher-performing nuclear reactors. Recent laboratory tests involving 3D-printed electrically conductive models of the INFLUX lattice demonstrated that the TPMS geometry transfers heat about three times more efficiently than conventional fuel rods. This improvement could allow for thinner fuel, lower operating temperatures, and reduced thermal stress, enhancing reactor performance and economics. Manufacturing challenges remain due

Researchers at Oregon State University have developed a sustainable, clay-based 3D-printable construction material designed to address both environmental and speed challenges in building. Traditional cement production is a major contributor to global CO2 emissions and requires a lengthy curing time of up to 28 days. The new material uses frontal polymerization with an acrylamide-based binder, allowing it to cure instantly as it is printed. This rapid curing enables the construction of multilayer walls and freestanding structures immediately, reaching residential concrete strength (over 17 megapascals) within three days—significantly faster than conventional concrete. The eco-friendly composite is made primarily from soil, hemp fibers, sand, and biochar, a carbon-rich byproduct that helps sequester carbon, thereby reducing the carbon footprint compared to traditional cement. This innovation is particularly promising for rapid shelter construction in disaster-stricken areas, where speed and sustainability are critical. While current costs are higher than standard concrete, the research team aims to reduce expenses and

Researchers at the University of Toronto Engineering have developed a novel lightweight and extremely strong metal matrix composite capable of withstanding temperatures up to 932°F (500°C), making it highly promising for aerospace and other high-performance applications. The material mimics the structure of reinforced concrete on a microscopic scale, featuring a titanium alloy mesh acting as "rebar" surrounded by a matrix composed of aluminum, silicon, magnesium, and embedded alumina and silicon nanoprecipitates. This design, enabled by additive manufacturing and micro-casting techniques, allows precise control over the composite’s microstructure, resulting in exceptional strength and thermal resistance. Testing revealed that the composite exhibits a yield strength of around 700 megapascals at room temperature—significantly higher than typical aluminum matrices—and maintains 300 to 400 megapascals at 500°C, compared to just 5 megapascals for conventional aluminum alloys. This performance rivals medium-range steels but at roughly one-third the weight, addressing a critical limitation of aluminum alloys

The article discusses Alloy Enterprises, a startup addressing the escalating cooling challenges posed by increasingly power-hungry AI data center racks. Nvidia recently revealed that future GPU racks, expected in 2027, could consume up to 600 kilowatts of electricity—nearly double the capacity of some fast EV chargers. This surge in power density creates significant heat dissipation issues, especially for peripheral chips like memory and networking hardware, which account for about 20% of a server’s cooling load but currently lack effective cooling solutions. Alloy Enterprises has developed a novel cooling technology using stacks of copper sheets bonded through a process called diffusion bonding or "stack forging," producing seamless, solid metal cold plates that can fit into tight spaces and withstand high liquid cooling pressures. Unlike conventional machined cold plates, which are assembled from separate halves and prone to leaks at seams, Alloy’s stack forging method creates single-block copper plates with no seams and superior structural integrity. This process also allows for finer features—down to 50 mic

Researchers at the Fraunhofer Cluster of Excellence Programmable Materials (CPM) have developed a novel finger joint made from a single piece of programmable metamaterial, called the ProFi (Programmable Multistable Finger) project. This motor-less finger can lock into four stable positions without the need for screws, hinges, or multiple interconnected parts, simplifying the design of hand prostheses and robotic grippers. The finger bends along one axis in 30-degree increments, enabling distinct gripping, resting, or gesturing positions. The design was validated through finite element method simulations to ensure durability and stiffness, and was produced using additive manufacturing techniques like Fused Deposition Modeling and Selective Laser Sintering, allowing for easier customization and assembly-free fabrication. The key innovation lies in the integration of bistable unit cells—elastic beams that snap between stable states without continuous force—within the joint’s internal structure. Using specialized software (ProgMatCode), researchers optimized these cells to create a passive multistable mechanism

OpenVCAD is a new open-source software tool developed at the University of Colorado Boulder that revolutionizes multi-material 3D design by enabling engineers to create objects with smooth material gradients through code-driven precision. Unlike traditional CAD tools that define only an object’s outer boundaries and assume a single interior material, OpenVCAD allows users to assign complex mathematical functions to represent spatially varying materials within a 3D object. This capability simplifies the design of gradient objects—such as shoe soles transitioning from firm to soft—by letting users update designs through small code changes rather than redrawing entire models. Created in the Matter Assembly Computation Lab under Assistant Professor Robert MacCurdy and developed by PhD student Charles Wade, OpenVCAD supports multi-material printing with up to five materials simultaneously and has demonstrated versatility across various 3D printers. Its applications extend beyond academia to fields like medical modeling, soft robotics, and structural engineering, where it can help create lifelike anatomical models, flexible robotic actuators, and

Researchers at EPFL have developed a novel 3D printing method that creates ultra-strong metal and ceramic materials by growing them inside a water-based hydrogel scaffold. Unlike traditional approaches that harden resin pre-infused with metal precursors using light, this technique first prints a simple hydrogel structure, which is then infused repeatedly with metal salts and chemically converted into metal-containing nanoparticles. This post-printing material infusion allows for high metal concentrations and results in dense, intricate architectures with significantly improved mechanical properties. The new materials can withstand pressures up to 20 times greater than those produced by previous methods while exhibiting only about 20% shrinkage compared to the typical 60-90%. The team demonstrated the method’s versatility by fabricating complex gyroid lattice structures from iron, silver, and copper, which are strong yet lightweight. This approach is promising for advanced applications requiring complex 3D architectures that combine strength and low weight, such as sensors, biomedical devices, and energy conversion or storage technologies.

Researchers at MIT have developed a novel printable aluminum alloy that is reportedly five times stronger than traditionally manufactured aluminum and can withstand high temperatures. Using a machine learning (ML)-based approach combined with simulations, the team evaluated only 40 possible material compositions—significantly fewer than the over one million combinations typically required—to identify an optimal mix of aluminum and other elements. This alloy exhibits a high volume fraction of small precipitates, which contribute to its enhanced strength, surpassing previous benchmarks including the wrought Al 7075 alloy. The new alloy, produced via 3D printing rather than conventional casting, benefits from rapid solidification that prevents precipitate growth, resulting in superior mechanical properties. After aging at 400 °C for eight hours, the alloy achieves a tensile strength of 395 MPa at room temperature, about 50% stronger than the best-known printable aluminum alloys. The researchers envision applications in lightweight, temperature-resistant components such as jet engine fan blades—traditionally made from heavier and more expensive

Researchers at the US Department of Energy’s Argonne National Laboratory have conducted studies on 3D-printed stainless steels to support the development of next-generation nuclear reactor components. Using laser powder bed fusion (LPBF), an additive manufacturing technique, they produced samples of two key alloys: 316H, a conventional stainless steel used in reactors, and Alloy 709 (A709), a newer alloy designed for advanced nuclear applications. The LPBF process creates unique microstructural features due to rapid heating and cooling, including numerous dislocations that can both strengthen the steel and increase its susceptibility to fracture. Heat treatments are applied to relieve stress by allowing atomic rearrangement, but some dislocations may be retained to enhance performance. The studies revealed significant differences between 3D-printed and conventionally wrought steels, particularly in how the printed materials respond to heat treatments. For 316H, experiments using advanced microscopy and in situ X-ray diffraction showed that nano oxides—common defects in 3D-printed

A research team led by Jonathan David Blutinger, PhD, has achieved a significant breakthrough in 3D-printed food by creating a 14-ingredient, three-course meal using multi-wavelength laser cooking. This novel technique employs multiple laser wavelengths to precisely control the texture of printed foods during the printing process, addressing one of the biggest challenges in 3D food printing—replicating the texture of traditionally cooked meals. Unlike conventional ovens or stovetops that apply heat unevenly, lasers deliver targeted energy bursts at shallow depths, enabling fine-tuning of elasticity, firmness, and chewiness across different layers of the food. The team tested blue, near-infrared, and mid-infrared lasers on Graham cracker dough and found that laser cooking could achieve peak elasticity at mid-strain levels, surpassing the texture quality of oven-baked samples. By modulating laser exposure frequency, they engineered the internal structure of the dough with precision. This advancement allowed them to produce the most complex

Researchers in China have developed a novel 3D printable bio-active glass scaffold that shows promise as a bone replacement material. Unlike traditional glass, which is brittle and difficult to shape safely for medical use, this new bio-glass combines silica particles with calcium and phosphate ions to form a printable gel. This gel can be hardened at a relatively low temperature (1,300°F), avoiding the toxic plasticizers and extreme heat (above 2,000°F) typically required in glass 3D printing. In animal tests involving rabbit skull repair, the bio-glass scaffold supported sustained bone cell growth over eight weeks, outperforming plain silica glass and nearly matching a leading commercial dental bone substitute in durability.

Engineers at the Royal Melbourne Institute of Technology (RMIT) have developed a new 3D-printed titanium alloy that is about one-third cheaper and stronger than the current industry standard, such as Ti-6Al-4V. This cost reduction is achieved by replacing the expensive element vanadium with more accessible, lower-cost materials. The new alloy also overcomes a common issue in 3D-printed metals by avoiding the formation of columnar microstructures, resulting in a uniform grain structure that enhances both strength and ductility. These improvements address key challenges that have hindered the widespread adoption of 3D-printed titanium in aerospace and medical device industries. The research introduces a novel framework for designing metallic alloys tailored specifically for additive manufacturing, moving beyond legacy alloys that limit the potential of 3D printing.
